Steve tests the Gabil 7350T antenna, Gabil GRA-ULT01 tripod, and BaMaKeY TP-III paddles

Many thanks to Steve (MW0SAW) who shares the following field report:


Mini Field Report: Testing the Gabil 7350T and BaMaTech TP-III on a brisk SOTA activation!

by Steve (MW0SAW)

Went for an early walk/SOTA activation up Fan Fawr GW/SW-005 (734m) this morning (9/4/23). I think someone said it was supposed to be the hottest day of the year in the UK. It was about 5 deg celsius with a bitter wind chill of -2c on the summit! It’s very close to the highest peak in South Wales, Pen Y Fan (886m).

As I mentioned a couple of weeks ago in our emails, I wanted to test a new compact antenna I purchased recently, called the Gabil 7350T in the USA, and branded as the Sharman MD-3500 in the UK where I got mine. I also took the Gabil GRA-ULT01 MK2 tripod which I did purchase from the USA on Amazon.com.

Another first for the the activation was the Bamatech TP-III ultra compact paddle, Dinos were included 🙂

Starting my walk, the lovely view of the reservoir quickly disappeared and was the last view I would see ascending into the mist.

I took refuge in my Decathlon 1 man camping shelter, setting up the tripod and antenna close by.

The wind was howling and turning my back the antenna toppled over. This was quickly resolved with a tent peg on one of the tripod legs. Quick setting of the slider with the analyser got 1.2 SWR and so after a slurp of coffee, I started to call CQ on 20m CW. A nice stream of European qsos ensued with good reports (many 599), it was pleasing to hear with such a small antenna (about 8 ft). Just as the contacts were drying up, I was taken aback by a strong VK station! Always great feeling to get some dx like that but especially pleasing with this tiny antenna on its maiden voyage 🙂

I switched to 20m SSB for a few more QSOs but struggled with QRM on two frequencies. My allotted time was running low and my fingers were numb, so I packed up the HF and got the handie out to catch a few local VHF contacts.

So what can I summarise from this activation, well I can safely say I love the Gabil/Sharman antenna and Gabil tripod. They would make a really nice additional to a small go bag, they seemed to work almost as good as a full size 1/4 on 20m. Time was limited this trip and I was too cold to hang about to try more bands, but extremely pleased with the performance so far.

The Bamatech key is a pure work of art, beautifully made, sensitive and precise. Probably my best portable key to date in my collection.

POTA at Fort Dobbs: Testing a BCI filter and depleting a battery!

Friday, March 17, 2023 was a dreary, rainy day.

It was the sort of day made for reading a good book by the fireplace or…in my case…activating a park!

I don’t let rain stop me from playing radio in the field. I carry a rain fly in my car pretty much all of the time so if push comes to shove, I can create a dry space to play radio.

That said, a number of parks I frequent have large covered picnic shelters, so why not use what’s already there?

That particular Friday, I had one particular park and one particular goal in mind.

G106 + BCI Filter

As I mentioned in a post this weekend, I purchased and built a K9DP BCI Filter Kit.

If you’d like to see photos of the build, check out this post.

I built this BCI filter specifically to pair with the Xiegu G106 transceiver. Why? Because the G106 is prone to overload if you’re anywhere near an AM broadcaster.

The last time I visited Fort Dobbs State Historic Site (K-6839), a local AM broadcaster bled through the audio of the G106. I was able to complete the activation without any issues at all–in fact, it was a very successful activation (read the report here).

Still, I did feel that the receiver was a bit less sensitive due to the broadcaster overwhelming the front end of the radio.

That Friday, I wanted to pair my Xiegu G106 with the new in-line BCI filter to see if that might mitigate the interference I experienced before.

After arriving at Fort Dobbs, and before taking my gear out of the car, I made my way to the park office (in the log cabin at the end of the sidewalk above) and asked for permission to use their picnic shelter. Continue reading POTA at Fort Dobbs: Testing a BCI filter and depleting a battery!

Assembling a K9DP BCI Filter Kit (Photos)


If you own a Xiegu G106, X6100, or any other radio that is prone to overloading when in the presence of an AM broadcaster, you should consider building an in-line BCI filter!

As many of you know, I’ve been testing the Xiegu G106 over the past couple of months for a review that will be published in the May 2023 issue of The Spectrum Monitor magazine.

One criticism of the G106 is that its front-end overloads when there’s an AM broadcaster within a few miles of where you choose to operate. The Xiegu X6100 is identical in this regard.

One quick way to remedy this is to build or buy a BCI filter. We’ve mentioned in the past how you can homebrew them and I planned to do so. After checking my parts drawer, though, I realized I needed to buy a capacitor, toroids and at least one of the two BNC connectors needed if I wanted an in-line filter in a small project box.

I decided it would be much easier to simply buy a kit and, based on a tip from a reader here on QRPer.com, I purchased one from Dan (K9DP). Continue reading Assembling a K9DP BCI Filter Kit (Photos)

First look at the Blue Ridge Overland Gear Gadget Bag

In early February, Jeff (KD4VMI) sent the following message to me:

Good evening. Love your YouTube videos and QRPer posts and, from them, I know you appreciate rugged packs and gear.

I enjoy POTA, although I don’t get out as often as I’d like, but I’ve found Blue Ridge Overland Gear’s various bags and modular systems to be very handy for bundling my radios, batteries, cables, and antennas.

It’s been on my mind for some time to let you know about them (if you don’t know about them already) and I finally decided to take the time to write you. I’m not associated with them in any way, and I didn’t approach them about passing this on to you, or anything like that. I just really appreciate their gear and I think you might, too.

The BROG materials are high quality and stout, the zippers are beefy and smooth, everything is double or triple stitched and everything is modular so it can be used for just about anything, and in pretty much endless combinations with their various bags and gear.

Their products are not overly cheap, but are guaranteed for life. They’re located in Bedford, Virginia and all their things are made in the USA (I think mostly in Bedford).

I often use their tire puncture repair kit bag, for instance, to carry my FT-891, Bioenno battery, cables and mic, and PackTenna, and then strap the coax to the Molle system on the front of the bag.

They posted a YouTube video showing their gadget bag with accessory pouches for HTs, etc.

Their website is: https://www.blueridgeoverlandgear.com/.

Anyway, I appreciate all you do for our great hobby and just wanted to share this info.

Take care and all the best to you and yours…

Thank you so much for the kind words, Jeff, and for the tip about Blue Ridge Overland Gear (BROG). You’re obviously a skilled pack enabler because you had my attention by the second paragraph–!

Shortly after my exchange with Jeff, I checked out the BROG website and was really impressed with their line-up of packs and gear–all with a focus on modular organization, especially in-vehicle since it’s for Overlanding. It’s just the icing on the cake that their gear is made in the USA.

I was very curious if their Gadget Bag, in particular, would lend itself to being a modular flied radio kit pack.

Thing is, there are so many options and configurations for the Gadget Bag, I wasn’t entirely sure what to order.

Being a fellow who expects to pay a premium for rugged products, made in the USA–especially ones that carry a lifetime warranty–I was prepared for some sticker shock. Turns out, BROG pricing is pretty reasonable in comparison with other cottage industry pack manufactures.

Still, I wasn’t quite sure how easily some of my radios and gear might fit in their zippered pouches, so I reached out to BROG–mentioning QRPer and my constant search for field radio packs–and asked if I could order some packs and pouches, test them with my radio gear, then pay for what I decided to keep.  I didn’t want free gear, I just couldn’t tell based on the product images and posted dimensions what pouches and packs might fit my various radios and accessories. Also, I knew readers might ask if certain pouches and packs might fit certain radios.

The good folks at BROG kindly obliged, so I asked for the following list of items:

– QTY 1 Gadget Bag (shell) in black
– QTY 3 Large Velcro Pouches
– QTY 6 Medium Velcro Pouches
– QTY 1 Velcro Cord Keeper
– QTY 1 Medium GP Pouch
– QTY 1 Velcro Headrest
– QTY 1 Headrest Pouch Kit

Some of these items weren’t in stock, so it was a week or so later when I received notification that the package had shipped. It arrived a couple days later.

I love the feed bag style packaging, by the way.

Although you’ll start to see this field kit in upcoming activation videos, I thought I share a photo tour of this pack… Continue reading First look at the Blue Ridge Overland Gear Gadget Bag

Truly an amazing portable speaker for your favorite QRP radio

A couple weeks ago, Mike posted an article about his search for the best field-portable amplified speaker.

His top pick was the Anker Soundcore Mini.

I must say: he was spot-on!

I know Mike well enough to trust his evaluation, so I purchased an Anker Soundcore Mini quite literally as I was formatting his article for QRPer.com.

It arrived via Amazon, but I had such a busy week, I didn’t get a chance to truly test it until this weekend when I hooked it up to my Elecraft K2 in the shack. I feel like the K2 has a very decent speaker, but the Anker is even better.

This afternoon, I did a POTA activation at K-6856 and, to properly test the Anker Soundcore Mini, I paired it with my Elecraft KX3.

While the KX3 is one of the finest field radios on the market, its built-in speaker isn’t its strong suit.  The audio is pretty anemic (especially if you’re K4SWL and do real-time, real-life activation videos–!) 🙂 Truth be told, it’s one of the reasons I don’t take the KX3 to the field more often. I’d rather not do a separate audio recording (line-out) then harmonize it in post-production.

I used the Anker Soundcore Mini for the full activation and it worked beautifully. I love the audio, the size, the run time (something like 14 hours per charge, supposedly), and the overall build quality. I’ve never been disappointed with Anker products and I feel like this one is a great value at $24.99 via Amazon (affiliate link!).

Thanks so much for the suggestion, Mike!

FYI: the field report and video of this activation will be posted in three weeks or so!

POTA Audio: Mike’s search for the best field-portable amplified speaker

Many thanks to Mike (KE8PTX) who shares the following:


The search for the best portable speaker for ham radio.

Welcome to the end of my exhausting search for what maybe the best speaker for portable ham radio.

My list of requirements was short: it had to be small, amplified, and have an internal battery.

But most importantly, it had to have a AUX input.

The last requirement shortened the list very quickly. Most speakers today that have any quality of build are lacking in the old fashion AUX connection.

I tried a minimum of six speaker and even tried making one of my own. Rich sound quality was not most important factor to me. Let’s face it: we are not listening to the Beatles.

Now we are going to focus in the two that made the cut. On the bigger side was the JBL Charge 4. Rugged? Yes. Battery life? Great. Size and weight? OK. Take it from the car to the picnic table ok? Yes. Throwing in the pack for a SOTA or a long hike? Not the best choice.

Now to my #1 choice…

The Anker Soundcore Mini

  • Size is 67mm tall and 67mm dia.
  • Weight is 7.2oz
  • Case is made of aluminum all-around including the speaker grill.
  • External features are:
    • power switch,
    • USB charging port,
    • micro SD card slot,
    • and the must-have AUX port for connecting to my KX3.
  • It also has external rubberized volume control.
  • For those that may need bluetooth it has that also.

All in all, it is super rugged unit with great battery life and small for my QRP go kit. The only thing that comes in the box is the speaker and usb charging cord.

I hope my findings help others in search of a portable speaker.

Thank you for sharing this, Mike. I’m often asked about the portable speaker I use in the field. It’s a Sony SRS-XB12, but the only good source of them is eBay because they’ve been discontinued for so long.

This Anker speaker seems to be the same size and sport the same features of the Sony, at a slightly lower cost. I’ve also had very good luck with Anker products in the past (I’ve had some of their ear buds and several of their battery banks). In fact, I’ve just ordered this speaker because the battery life is also much better than that of my Sony speakers. I’ll plan to take this to the field and include it in my activation videos–I’ve give the Sony speakers to my daughters.

Thanks for sharing, Mike! 

N2HTT’s Xiegu X5105 3D-Printed Frame

Some of you might be familiar with Mike (N2HTT)’s Etsy Shop, HamGear3d.

Mike is a long-time QRPer reader/subscriber who designs 3D-printed radio frames for select QRP radios. In the past, Mike has designed frames for radios in his own collection including one for the LnR Precision LD-11, Xiegu X6100, Icom IC-705, and now the Xiegu X5105. Mike has also kindly sent me frames for many of these radios (knowing I also have them in my collection).

Mike has never asked to be plugged or promoted–in fact, the first frame he sent me was for my daughter’s radio–but I think his radio frames are functional and well-designed, so I’m happy to share info here on QRPer.com.

A couple months ago, Mike sent me a frame for the Xiegu X5105 and I realized yesterday that I never posted photos of it. 

Like his X6100 frame, the X5105 frame fits around the radio; assembly is very simple (and well-documented on his website) and it doesn’t require modifying the radio in any way. It simply friction fits around the radio and is secured, thus can also be removed quite easily. 

The frame, I’ve found, also protect the X5105 power button from accidentally being turned on in transit!

Below, I’ve posted a few photos of the Xiegu X5105 frame.

Thanks, again, Mike for sending me this radio frame. Very kind of you. Note that Mike can add your callsign to the front screen protector of the radio frame at no additional cost.

Elecraft AX1 Test Using American Radio Supply AM-801 Window Mount

Many thanks to Conrad (N2YCH) who shares the following field report:


AX1 Test using American Radio Supply AM-801 Window Mount: POTA Activation at Stuart B. McKinney Wildlife Refuge, K-0228

February 19, 2023

By: Conrad Trautmann (N2YCH)

If you’ve been reading the posts here on QRPer.com lately, you probably already know that the Elecraft AX1 has proven to be an excellent antenna for POTA activations for CW, SSB and Digital modes.

Personally, I used it for a New York City POTA rove I did at the end of 2022 and was able to activate four parks in one day all over Manhattan.

Recently, Alan, W2AEW contributed a story to QRPer.com detailing how he used a window bracket he constructed with an AX1 to do a CW park activation from his car. I’ve actually done a few digital activations from the car using the AX1, however, I used the tripod with the Elecraft tripod adapter and ran coax to it out the window and draped the counterpoise down the hood or trunk. This has worked well except for windy days where it would blow over. I was intrigued by the possibility of using the window mount and a number of the commenters to Alan’s post suggested sources for these types of mounts. I ended up ordering an AM-801 from American Radio Supply.

https://www.americanradiosupply.com/am-801-window-antenna-mount-bnc-connectors/

Since the AX1 depends on a counterpoise wire to operate properly, the first thing I did after receiving the AM-801 mount was to drill a hole in the base for a screw and a wing nut. The base is painted black, so I got my continuity meter out to double check that the screw was making a good ground, which it was. I had to bend the mount up slightly for the antenna to be vertical, since my Jeep windows don’t have much of an angle to them. I’m sure it would be just right for most cars.

My next step was to give it a try. Continue reading Elecraft AX1 Test Using American Radio Supply AM-801 Window Mount

Jim’s “WD-PT-PB” AX1/AX2 table/bench clamp mount


Many thanks to Jim (N9EET) who writes:

Thomas:

I look forward to all your videos and am enjoying how you use the Elecraft AX-1 in the field.

I have built the “WD-PT-PB” attachment for my AX-1 antenna.

That is, it is for Windy Day-Picnic Table-Park Bench use. It can be set up horizontally or vertically on the edge of a picnic table or at any angle on the back of a park bench and is a secure attachment for the AX-1 off the radio.

[I] bought the bolts straight and put them thru a random C clamp secured with a nut or wing nut and then bent one in my vise. Loosen the wing nut and angle the bolt any way I want and tighten the wing nut.

The pictures show it better than paragraphs of a description.

That’s brilliant, Jim! I love how versatile the clamp is and that it even fits in your Maxpedition pouch! No doubt, it’ll help the AX1 (or AX2, or any similar antenna) survive the windiest of deployments.

Thank you for sharing.

Elecraft’s KX2 Internal Battery Charger with RTC, the KXIBC2, is now shipping

Elecraft KX2 owners that follow Elecraft’s email discussion groups have heard that the new KX2 internal battery charger, the KXIBC2, has been tested and would soon be available for purchase.

I checked the Elecraft website this morning and the KXIBC2 has been added to the KX2 product page within the past 12 hours or so.

There are two model numbers:

  • KXIBC2-F: The “F” in the model number indicates that it will be factory installed with a new KX2 order.
  • KXIBC2: This is the part you would order if you already own a KX2 and plan to install it yourself. This one is referred to as the “Kit” version since the user installs it.

The price is $139.95 US plus shipping.

I just ordered the Kit version and paid a total of $149.30 US with shipping.

According to Elecraft, the kit version is actually very simple to install, but there’s an option to have the factory install it for you via an RMA. Elecraft notes:

Anyone with a modest amount of soldering experience should be able to do the KXIBC2 installation. Based on lots of feedback from field testers, we dramatically simplified the installation procedure. For field installation, we recommend “Method 1” (see the revision B2 instruction manual or later). There’s no need to do any disassembly other than removing and replacing the right side panel. And there are only two wires to solder. If after having a look at the instructions you feel that you’d rather let Elecraft to the job, we’ll be happy to. Simply contact [email protected] to obtain an RMA.

I’ve been looking forward to this particular KX2 upgrade.

While I don’t find removing the internal battery, charging it, then replacing it very cumbersome–I’ve literally done this hundreds of times–the new internal charger will make topping off the battery that much easier.

The KXIBC2 replaces the previous KXIO2 Real-Time-Clock optional module. If you have the KXIO2 installed, you’ll need to remove it and replace it with the KXIBC2.

The KXIBC2 retains the RTC (real-time-clock) function.

For more information about the KXIBC2 module, check out the product manual and installation guide here (PDF).
