[UPDATE: Thank you for the assistance! See procedure below.]
You may recall that I’m evaluating the X5105 on loan from Radioddity. Overall, I’ve been pretty impressed with this budget transceiver when I’ve taken it to the field.
I need a mystery solved though: How in the heck does one set up and use CW memory keying–?
The owner’s manual has been no help and I actually feel like it’s referencing an earlier firmware version.
In fact, from what I gather reading the earliest manual, it used to be super simple to both record and play back CW memory keyer messages. There were three memories labeled RE1, RE2, and RE3 that you could activate with three of the four quick menu buttons under the display. I would love that sort of accessibility, but I gather it’s no longer an option.
I’ve yet to find an explanation for using CW memory keying in the current version of the X5105 firmware.
Please comment if you could describe the procedure or point me to documentation that explains it. I could really use your guidance! Thank you in advance!
Update: How to use X5105 CW Memory Keying
Many thanks to Gary (KE2YK) and many others for the following procedure:
To configure the 10 CW memory messages:
Go to Menu 3 by pressing the MENU button until 3 appears beneath the power meter on the display.
Hit MSG
Select MSG number with VFO (Tuning Knob)
Press the EDIT button
Scroll through letters / numbers with the VFO and hit INS for each selection
When letter/number selections are complete, press SAVE
Repeat for each custom message and when done, hit QUIT
To play the preset messages:
Go to Menu 5 by pressing the MENU button until 5 appears beneath the power meter on the display.
Select DIGI
Select CWDEM from mode choices (leftmost button in menu 5) by pressing the button until CWDEM appears
Repeatedly hit MSG to select specific message number
Press PTT on body of rig or perhaps press PTT on mic. This will send the selected message one time.
To exit, hit MENU for other menu selections
No doubt, for CW memory playback, this is cumbersome. In fact, if Xiegu doesn’t update the firmware with an easier way to initiate playback (as they had in the original firmware version), I see that I’ll only use memory position 1 for calling CQ. I wouldn’t want to go through the trouble of selecting a different message for playback in the field and in the middle of an exchange. That’s just too clunky to be practical.
I’ve sent a note to Xiegu about this. With any luck, perhaps they’ll improve the firmware for easier operation.
Thank you again, readers for sorting out the mystery!
Thank you for sharing this, Pete! Sadly, I was unable to attend live due to my schedule, so am very happy to see these excellent presentations. I do hope that things will be normal next year and FDIM will happen in person again. If you attend the Hamvention, I strongly encourage you to also take in FDIM–it is always an amazing event.
When I pack all of my radio gear in a field kit that is compact enough to fit in a small day pack, it forces me to only take the essentials. This, in turn, makes for a quick deployment and pack-up.
I think this is one of the reasons I find Summits On The Air so appealing.
On Tuesday, May 18, 2021, I had a hankering to fit in a hike and, of course, play radio. I also wanted the option to fit in two activations, so needed a simple and short hike to minimize time.
Tuttle Educational State Forest (K-4861)
I decided to head to Tuttle Educational State Forest–one of my favorite accessible POTA sites–because their two mile loop trail was just what the doctor ordered. In fact, I knew exactly where I wanted to set up on the trail.
Tuttle is rarely busy–especially on a Tuesday afternoon.
I arrived on site and, as I was pulling my backpack out of the car, I was greeted by one of the Tuttle park rangers. He was incredibly nice and provided me with even more ideas of places to set up in the future along the trail and trail extensions. We must have chatted for 15-20 minutes–he had a number of questions about amateur radio and I never miss an opportunity to be an ambassador for both ham radio and POTA/WWFF.
The hike was amazing and, besides park rangers, I had the entire site to myself. About 1.5 miles into the hike, I found the spot I earmarked for this activation: a little open area with three wood benches on the side of the path.
This particular deployment reminded me how thankful I am that I discovered the Arborist Throw Line last year. I had the PackTenna deployed in three minutes.
It was so…effortless.
I decided to take the Xiegu X5105 out for another activation. Radioddity sent this to me on loan for a full evaluation and review. The previous day, I activated the Blue Ridge Parkway with the X5105. I wanted to see how many activations I could accomplish off of one charge of the X5105’s internal battery, so after the BRP activation, I didn’t re-charge the battery.
As insurance at Tuttle, I brought along my trusty QRP Ranger LiFePo4 battery pack and hooked it up to the X5105. If the X5105’s internal battery died on me, it would be easy to simply turn on the QRP Ranger’s power switch and hop right back on the air.
I started one of my real-time, real-life activation videos (see below), then called CQ on 40 meters.
Maybe that quick antenna deployment was foreshadowing the activation, because in the span of 13 minutes, I logged 11 stations all on 40 meters.
I was very pleased to work P2P (Park To Park) contacts my friends Steve (KC5F) and Scott (KN3A). Thanks, guys, for hunting me!
Here’s my log:
I didn’t even move up to 30 or 20 meters after working the string of contacts on 40 meters because Tuttle is far from being a rare site and I wanted to fit in one more activation that afternoon.
The X5105’s internal battery easily powered the rig for the entire activation (perhaps a total time of 15 minutes). I suppose I’ll have to take it to yet another park on this same charge!
Packing up was nearly as quick as deployment. I owe thanks to one of my YouTube Channel subscribers for suggesting that I pack the Arborist Throw Line pouch by winding figure eight bundles of line on my hand (much like I do with antenna wire) and stuffing them in the pouch one bunch at a time. This saved me a lot of time.
While the portable throw line pouch isn’t as quick to pack as the throw line cube, this method made it a cinch! I can’t find who originally made the suggestion, but I’m grateful–thank you!
During my loop hike, I snapped a few photos (click to enlarge):
Well hello there, little fella’!
I’m most grateful to the late Ms. Tuttle for leaving this amazing park for all to enjoy. Her legacy protects this land for all future generations.
When you’re doing a park or summit activation, don’t forget to stop and take in a good dose of nature and the outdoors.
It does us all a world of good.
More X5105 thoughts
This second activation had me warming up a bit more to the X5105. I do like its size, and I think it’s a good rig for CW ops.
CW operation is very pleasant, actually, and keying feels natural. I was impressed that the battery held for a second activation, even though this was a very short one.
Again, I think the internal speaker audio leaves a bit to be desired–I dislike the audio splatter I hear at higher volumes–but for $550? It’s really hard to be critical.
During this activation, I still hadn’t learned how to program CW memory keying. A YouTube subscriber recently described the process and it seems overly cumbersome and much more complicated than it was in an earlier firmware version. I’m going to contact Xiegu about this. Unless I’m missing something, it really holds the radio back from being pretty stellar on CW for the field op.
Readers, if you own the X5105 and can describe the best way to use CW memory keying, please comment with directions! I’d really appreciate it!
Thank you
Thank you once again for reading through this field report and perhaps watching the activation video.
I’d also like to thank the readers and subscribers who’ve recently supported me on Patreon and via PayPal. I am humbled and honored.
Thomas, my MFJ 1984MP arrived today so looking forward to using a resonant antenna with my 705 but also have the LDG Z-100Plus tuner as a back up.
I’ve seen many antennas that have a winder built in allowing the user to wind in a figure eight fashion. It might help keep the kinks down.
I have fashioned a cord winder for the MFJ 1984 EFHW Antenna. It is a winder made for electrical drop cords and comes in a 3 pack at Lowe’s. Very inexpensive solution for adding it to the MFJ antenna with a couple of zip ties. I’m set to go works some POTA with an efficient antenna. Thanks for your videos deploying the MFJ antenna in the field.
Thank you for sharing this tip, Max! I like how you can so easily secure the antenna to the extension cord winder with cable ties.
Looks like our Prayers have been answer! 160 – 10, 5 Watts, single side band using a new transmitting technique , no more DSB!
All for 80 bucks (includes 3 band modules)
The v. III version debuts a novel firmware scheme for our Si5351A/MS5351M VFO which allows a move away from DSB transmission to SSB, by a new process we are calling AFP-FSK (Audio Frequency Processed-FSK).
Many thanks to Don (W7SSB) who notes that the TX-500 has now received CE certification. Lab599’s European distributor, PileUpDX has posted the following message on their website:
We are happy to announce that the long process with CE certification of the TX-500 transceiver from Lab599 has finally been completed. This week the notified body contracted to do testing and evaluation issued their certificate proving that the TX-500 meets the requirements to be sold on the EU market.
Now the next step is to complete the necessary documentation and marking including CE labelling of the radio itself and its packaging. Meanwhile the production of the first batch of transceivers for the EU market is ongoing and estimated to be completed in middle of June. If everything goes according to plan we should be able to start fill first batch preorders sometime during the end of June or beginning of July.
If you are in the first batch of deliveries and have not prepaid your TX-500 we will shortly contact you with payment information.
I’ve gotten so many messages from readers and viewers in the EU and UK who have been eagerly awaiting TX-500 availability.
While this doesn’t mean immediate availability–obviously with an estimated first batch shipping end of June or early July 2021–it’s my understanding that CE certification has been a frustratingly slow process due to C-19 and a complete bottleneck for the manufacturer and distributor.
I learn a lot about a radio the first time I take it to the field. I’m not sure if it’s because being out of the shack helps me give it my full attention, or if it’s because field conditions vary and this allows me to see how flexible and adaptable the radio is.
On Monday (May 17, 2021), I was eager to hit the field with a new-to-me radio.
The previous week I didn’t log even one park or summit activation. Typically I’d hit at least two. There were a couple of reasons for this…
First, we had a fuel shortage in western NC and I didn’t want to burn any extra fuel for activations knowing we had some important family errands that week.
Secondly, I needed to hunker down and finish a number of projects I’d been working on including a lengthy two-part field radio kit feature for The Spectrum Monitor magazine, and a new in-depth TX-500 review for RadCom. FYI: Part one of my feature for TSM will appear as the cover article in the June 2021 issue.
We also had a number of family projects to sort out. So a week at home perfectly timed with the fuel shortage.
The new radio
I collect reader and viewer suggestions and when I see that there’s a radio or product, in particular, folks would like to see tested, I try to obtain one.
One of the most requested radios lately has been the Xiegu X5105.
A number of readers have asked me to obtain an X5105 and take it to the field. Many are considering purchasing this (incredibly) affordable full-featured QRP transceiver, others own it, love it, and want to see how I like it compared with my other radios.
Last year, I came very close to purchasing the X5105 for review, but opted for the Xiegu G90 instead (here’s my review of the G90).
Even though the X5105 is only $550 US, I really didn’t want to make a purchase at this point because I’m budgeting for a new MacBook, new video camera, and I just purchased the TX-500.
So I reached out to Radioddity who is a sponsor over at the SWLing Post. I’d been in touch with Radioddity a lot as of late because I’ve been evaluating and testing the Xiegu GSOC for the past few months. They lent me the GSOC (and a G90 because I sold after my review) and I was in the process of packing up both units to send back to them.
I asked if they could lend me an X5105 for a few weeks. They were quite happy to do so and dispatched one in short order.
A clear relationship
Side story…
Back when I decided to place ads on the SWLing Post and QRPer.com, I worried about any inherent conflicts of interest. I read magazines that review products and can tell that they’re being gentle in their criticism because there’s a two page ad of the product immediately following the review. I don’t like that.
This conflict is something that’s almost inevitable with any radio publication that grows to the point of needing monetization to support it.
I made a few Golden Rules up front:
1.) I would only place radio-relevant ads on my sites. Period.
2.) My ads and sponsorships would be hand-picked and by invite only. I choose who can be a sponsor.
3.) I’m up-front with sponsors that my reviews call it like it is. If they send me product to review, I will give it an honest evaluation based on real-life use. If I don’t like it or can’t recommend one of their products, I’ll let my community know.
I’ve lost a couple of sponsors over Golden Rule #3 over the years. I’m okay with that because I’d rather not allow an advertiser on my site that can’t take customer criticism.
I invited Radioddity to be a sponsor of the SWLing Post last year after I had some positive interactions with them.
The Xiegu GSOC
Radioddity sent me the new GSOC to review in November 2020. I discovered in short order that the GSOC had some major issues and, frankly, I didn’t like it and certainly couldn’t recommend it. I communicated my concerns about this product with detailed notes and suggestions for improvement. I was open and honest about the GSOC on the SWLing Post (read the thread here).
Radioddity not only embraced my criticisms but sent them to the manufacturer and thanked me.
Impressive.
Blue Ridge Parkway (K-3378)
But back to the activation!
So on Monday, May 17, I had an errand in town that took me right past the Blue Ridge Parkway Folk Arts Center. The detour to do an activation was maybe two minutes, so there was no “fuel-shortage” guilt! 🙂
Also, I had a good hour to burn before I needed to go home and pack for a quick trip to visit my folks.
I deployed the PackTenna 9:1 random wire antenna specifically because I wanted to see how easily the X5105’s internal ATU could match it.
I hopped on 40 meters first, hit the ATU button and it quickly found a 1:1 match–good sign!
This turned out to be a pretty easy and simple activation.
I started calling CQ and within 12 minutes I logged 11 stations.
I moved up to 20 meters knowing it would be a tougher band, but worked one more station–KG5OWB at K-0756–pretty quickly.
I was quite happy with logging 12 stations in short order. A nice contrast to recent activations where conditions were so poor it’s been a struggle to get even 10 contacts within an hour.
I would have stayed on the air longer but (as I mention in the video) I wasted a good 20-25 minutes waiting on the landscape crew to finish mowing on/around the site before I set up my station. I didn’t want to be in their way.
Here’s my log sheet from the POTA website:
Video
Of course, I made one of my real-time, real-life videos of the entire activation. I’ve quite a long preamble in this one, so if you’re interested in skipping straight to the on-the-air time, go to 16:24.
X5105 initial thoughts?
So far, I like the X5105. It certainly accomplishes its goal of being an all-in-one “shack in a box.”
I performed this activation only using the X5105 internal battery. In addition, the ATU worked perfectly with the random wire antenna.
I like the size–it’s much smaller than I imagined. It’s also fairly lightweight.
It feels rugged, too–I wouldn’t be concerned about it getting easily damaged in the field.
The speaker works pretty well, but if the volume level is pushed too hard, it starts to splatter. I wish it could handle a little more volume before the splattering kicks in.
The ergonomics are pretty good. It didn’t take long to sort out how to use most of the functions.
One area for improvement? The owner’s manual. It’s poorly written and (frankly) reads as if it was rushed to print.
For example, I wanted to set up CW memory keying prior to hitting the field. Unfortunately, the owner’s manual was no help.
There’s actually a dedicated page regarding CW memory keying, but the first thing it does is reference a different section of the manual (without giving a page number). I followed the procedure, but it didn’t work. In fact, it didn’t make sense as it seemed lead me down the path of digital mode macros. I think the manual may be referencing a procedure before the last firmware update (which, it appears, changed the menu structure significantly).
If you can help guide me through setting up CW memory keying, please comment! I’m sure it’s a simple process, but I haven’t sorted it out yet.
Overall, though? I see why the X5105 is so popular. It appears to compete with a loaded Elecraft KX2. It’s a bit larger, heavier, and less “refined” but it’s also half the price of a loaded KX2.
I also think it’s a great radio for CW operators. The keying feels natural and responsive. It uses relays instead of pin diode switching, so QSK includes a little relay clicking. I don’t find it to be too loud, though.
I’ll be taking the X5105 out again very soon. I’ve got it for 6 weeks, so it will get plenty of park and summit time. If you own the X5105, I’d love to hear your comments on this portable rig.
On the morning of May 10, 2021, I had a hankering to head to the Blue Ridge Parkway for a quick park activation.
I had a particular spot in mind–one that’s only two miles or so from my QTH as the crow flies. The only wrinkle in my plan was that we were expecting rain all morning and at our house we were in thick fog and light, steady rain.
Normally when I have these conditions, I look for a sheltered site, but I thought it might be a great time to take out the TX-500 since it’s weather-resistant. Why not, right?
I packed the lab599 Discovery TX-500, my Chameleon MPAS 2.0 vertical, and my Elecraft T1 antenna tuner to pair the two. I also brought along some rain gear.
Although the activation site is close to home as the crow flies, it actually takes about 30 minutes to drive there. By the time I reached the site, the skies were mostly clear and the sun was shining! This time of year, it reminds me of living in the UK: if you don’t like the weather, just wait five minutes.
This was very much a road side activation. The spot I chose isn’t an overlook–although it did provide amazing views–it was simple a pull-off.
This is where antennas like the MPAS 2.0 are so useful: they are self-supporting and very quick to deploy. Since I was set up right off the road, I also appreciate using verticals rather than wire antennas since the antenna and throw line aren’t in the way of others who might choose to park in the same pull-off. I can easily deploy the counterpoise and feedline so that it’s out of the way.
As with most park activations, I started on 40 meters CW and only operated 5 watts.
I quickly racked up five contacts on 40 meters, then the band fell silent.
I moved up to 30, then 20, down to 80, back to 60 and 40 again.
About 30 minutes had passed since I was last on 40 meters, so new hunters were checking the bands. I snagged a total of seven more contacts in about eleven minutes.
Obviously, 40 meters was the only band open that morning!
A quick note about 80 meters
I get a lot of questions from readers and YouTube subscribers about my use of the 80 meter band during the daytime.
I go into more detail about this in the video, but contrary to what many think, 80 meters can be a very useful daytime band for POTA activators.
While it’s true that you’re not going to work DX on 80 meters during the daylight hours (else, highly unlikely), you can still work local and regional stations.
Keep in mind that POTA, WWFF, and SOTA activations aren’t about working DX. DX is fun and perhaps a personal goal, but it has nothing to do with success in achieving a valid activation.
Basically, any contacts–DX or local–will get you what is needed for a valid activation.
If, like me, you live in a part of the country where there are a concentration of park and summit hunters/chasers within a daytime 80 meter footprint, then hop on that band and give it a go!
I’m not sure how useful this might be for activations in sparsely populated areas like Montana or the Dakotas, for example, but along the east and west coast, 80 meters is your friend.
At this particular activation, I didn’t didn’t employ an efficient antenna for 80 meters. While I’ve made numerous 80 meter contacts on the CHA MPAS 2.0 in the past, it’s just not physically large enough to be efficient on that band. The CHA Emcomm III Portable or another long wire antenna would have provided better results. But I knew that 40 meters and possibly 30 meters would be my best bet that day, so the MPAS 2.0 was a great choice.
Again: don’t forget about 80 meters. It’s helped me snag many an activation!
Video
Here’s my real-time, leal-life, no-edit video of the entire activation:
You might hear an audio pop when I’m keying on the TX-500. This is happening because I have the audio gain cranked up all the way for the video. While the speaker/mic can get quite loud, when I’ve got it located so far from the camera mic, I run it at 100% volume to be heard. I recently changed my CW T/R recovery time from 100ms to 400s which eliminated most of the audio popping.
Thank you for reading this field report! I hope you’re getting an opportunity to take your radios outdoors this week!
By request, I’ve just posted another transceiver comparison video. This time, we take a look at the lab599 Discovery TX-500 and Icom IC-705 to determine which radio might better suit your needs.
As I mention in the video, I see these portable QRP radios as being in two different classes:
the TX-500 for operators who want the most rugged, efficient, and weather-resistant general coverage transceiver currently on the market and
the IC-705 for operators who want the most feature-packed high-performance portable transceiver on the market
Both radios are excellent options for hams who, like me, prefer playing radio outdoors.
As I mentioned in the video, I knew I’d forget some important points while making the live recording. Here are some extra notes I wish I would have included:
SSB operation: Both radios have excellent features for the SSB operator including EQ settings for both transmit and receive which is a major plus for a QRP radio. I wouldn’t make a purchase decision based on SSB operation–both are excellent.
CW operation: CW operators will be pleased with both rigs. It’s important to note, though, that the TX-500 doesn’t have full break-in QSK like the IC-705. The TX-500 has at minimum a 100ms recovery time after keying a character. That’s a quick recovery, but not fast enough so that an operator can hear between characters formed; especially at high speeds. The IC-705 has full break-in QSK and it sounds great. Note that both the TX-500 and IC-705 use relays, not pin diode switching, so you can hear relays clicking inside the radio, but both are pretty quiet.
Protecting the IC-705: There are a number of IC-705 3rd party cages appearing on the market. These can be used to help protect the IC-705 in the field. Numerous readers and YouTube channel viewers have recommended the IC-705 Carry Cage by Peovi. From what I’ve seen, it looks to be the best of the bunch, but it doesn’t do a lot to protect the lower back portion of the radio–the part of the chassis that meets a surface. I feel like it’s not quite what I’d want, thus hard to justify $135 for it. Other aluminum and 3D printed cages seem to add too much bulk to the radio or obstruct some of the most common connection points on the sides (antenna, key, ATU control cable, speaker/mic, etc.).
TX-500 connectors and cables: The TX-500 uses GX12 mm connectors that are widely used in aviation, commercial and military applications. They’re easy to find online, but the price per each with shipping is typically around $7.00-8.00 US. You get a better deal if you buy in bulk, but often bulk packages of 5 or more are of the same pin count/configuration. W2ENY has posted a number of accessory cables, spare connectors and even a military-style handset on his eBay store and website. The Icom IC-705 uses more standard 1/8″ and smaller two and three conductor plugs.
Receiver Performance: Based on Rob Sherwood’s receiver test data table, the IC-705 has a performance edge over the TX-500. In the field, this difference is not noticeable. Indeed, both radios have very respectable numbers. If I had to choose one radio over the other if operating in a CW contest, for example, I’d give slight preference to the IC-705. I’ve used the TX-500 during a CW contest before, however, and found it did a brilliant job blocking tightly-spaced signals–click here to watch the short video.
As I was packing up my radio gear at the last activation I posted (click here for that field report), I paused to make a quick video and talk about my rucksack, my accessories pouches, and a winder I like to use with the MFJ-1984LP antenna.
Here are the products I mentioned:
GoRuck GR1 USA
This is one of my favorite rucksacks for SOTA activations. I like the fact that it’s low-profile, structured, and feels great on the back even during extended hiking sessions.
It’s also insanely rugged, weatherproof, and (frankly) over-engineered.
My GR1 was made in the USA by GoRuck. This company specializes in packs that are essentially designed to be used and abused. They’re all backed by a lifetime warranty. You pay for this kind of quality, though.
I purchased mine perhaps 3 years ago during a closeout sale on this particular color variant. When combined with my educator’s discount I think I paid around $210-220 US for it.
I originally bought it because I’m a huge fan of one-bag travel (read an article where I mention this on the SWLing Post). I discovered that the GR1 meets most airline regulations as a “personal carry on.” This means even with discount airlines and regional “puddle jumper” aircraft, I know I can always take it on board and never need to check it. I can easily travel one or two weeks out of this pack.
The TX-500, clipboard, and my logging pads all tuck away nicely in the GR1’s slip-in rucking plate pocket.
But in the field, the GR1 has the perfect amount of capacity for any of my QRP transceivers along with antennas, ATU, cables, and other accessories.
Being a one-bag traveller (and certified pack geek) I’m also a massive fan of US pack designer and manufacturer, Tom Bihn.
I have a number of their packs, pouches, and organizers.
Without a doubt, one of my favorite TB items is the Travel Tray. It’s a brilliant concept: take this with you on a trip, open it up as a tray in your hotel room, and place all of your valuables in it. By doing this, you don’t have to search your room for your watch, keys, wallet, glasses, phone, etc. When you leave the room, all of those easy-to-lose items will be in one place. If you’re in a rush to catch a flight, grab the whole pack by the drawstring, secure it, and throw it in your carry on! It’s a simple, genius little sack/tray!
I also use these to organize radio accessories in my field pack. For example, I have one now dedicated to the TX-500. In the Travel Tray, I store all of the TX-500 adapters and cords, the speaker mic, a set of CW Morse Pocket paddles, a PackTenna EFHW, some RG-316, and a 3 aH LiFePo4 battery. I even carry a spare Muji notepad in it in case I forget my logging pad. With this little bag and the TX-500, I have everything I need to hit the air!
Note that I much prefer the large TB Travel Tray. My wife has both a large and small travel tray, but I find that the small one is just a little too small for most everything I wish to put in it. The large one’s outer diameter is large enough that you can also store a short coil of RG-58 coaxial cable/feed line in it.
I love these so much, I purchased two more this week: one in black and one in coyote.
Thingiverse Wire Winder
This particular winder is red because that’s the filament my daughters had loaded in the printer at the time!
Before we purchased a 3D printer (an Ender 3 Pro) I would make wire winders out of anything I could find. With a 3D printer, however, it’s so easy to make a winder sized perfectly for your application.
You may have seen winders in various colors in my video field reports–they all come from a simple project file on Thingiverse.
This winder is super easy to print and to enlarge or shrink. If you don’t have a 3D printer, likely someone you know does! Ask them to print this for you. They’re incredible useful.
