Photos of a new Xiegu G106 HF transceiver [updated]

12 Comments

A friend who works in the amateur radio industry has shared the following photos and given me permission to post them.

These are images of the Xiegu G106 HF transceiver (click to enlarge):

As a field operator, one thing I noticed immediately are the protrusions around the faceplate that protect the encoder and what I assume in a multi-function knob. The form-factor seems to be roughly that of the Xiegu G90 (even smaller) with a backlit LCD display that resembles the Xiegu X5105 (only, again, much smaller).

I’m assured this isn’t vaporware, and I have to assume we’ll learn a lot more about the G106 soon.

The front panel is incredibly simple, so I must assume it’ll reply on menus for filter control, etc.

I have no other details at this point. When I learn more about the Xiegu G106, I’ll post updates here on QRPer.com.

Xiegu G1M replacement

Update (17 May 2022): I’ve just learned that the Xiegu G106 is the replacement for the Xiegu G1M . It’s sports 6 bands [actually, it might be more according to this update] has 5 watts of output power, and, of course, is SDR based like other Xiegu products. I’ve also learned it can receive wide band FM (hence the FM broadcast band image above).

Icom drops hints about the SHF-P1 controller prototype/concept

19 Comments

Yesterday, Icom posted the following teaser and image above on Twitter in advance of the 2022 Hamvention:

Are you ready for Dayton Hamvention 2022? Something new and exciting is on the horizon, visit us in building 2 from Friday, May 20 through Sunday, May 22.

At first, I was scratching my head because the product image (at the top of the page) looks like an IC-705, but the frequency displayed is 5.780 GHz.  Then I remembered mention of Icom’s SHF (Super High Frequency) Band Challenge some months ago.

I looked up the SHF Project page on Icom Japan’s website and found the details.

Basically, Icom seems to be repurposing the IC-705 platform to be used as a controller for the SHF transceiver. Why not? The IC-705 has fantastic ergonomics and a brilliant spectrum display.

In order to mitigate line losses, the SHF transceiver/RF module is designed to be mounted directly on a tower at the antenna and controlled remotely via a LAN cable. Here’s a simple diagram from Icom’s news release:

Here’s what the SHF RF module looks like:

Icom will have the new SHF-P1 controller prototype on display at the 2022 Hamvention:

I think it’s pretty cool that Icom’s working on a 2.4 GHz/5.6 GHz project even during these challenging times for manufacturers. I’ve never even tinkered in these frequency ranges, but I think it would be a lot of fun to explore.

Dale’s solution for enhanced CW field ergonomics

Many thanks to Dale (N3HXZ) who shares the following guest post:

Ergonomics of Operating CW in the Field

by Dale (N3HXZ)

About a year ago I started getting active in Parks On The Air (POTA) and Summits On The Air (SOTA). I had always been an avid hiker and backpacker, and though I am getting up there in years (recently retired!) these amateur radio opportunities were just the medicine I needed to rekindle my passion for the outdoors and amateur radio.

Thanks to Thomas (K4SWL) and his blog post and videos I was able to quickly come up to speed on the basics and get out into the field for CW activations.  I quickly discovered that operating CW in the field is quite different from operating at home. The creature comforts of a good chair, a level and spacious operating table, and isolation from the weather makes for a great experience in the shack, but is not available in the field, especially if you are backpacking to your destination. My early activations were sitting on a rock, or the ground, and using only a clip board to mount my rig (Elecraft KX2), locate my CW paddle, and place a notepad to record QSO’s.

While simple, this operating setup poses problems. Attaining and maintaining a flat workspace is tough in the field in order to keep things from shifting or falling off the clipboard, especially if you are not firmly seated. There is not enough space to set your wrist in order to steady your CW operating, and the notebook pages can flap in the wind, or the wind can blow your logbook clear off the table while operating. I realized I needed to upgrade my mobile station! Continue reading Dale’s solution for enhanced CW field ergonomics →

Why I’m skipping Hamvention this year

16 Comments

I made a tough choice a few weeks ago.

Since last year, I’ve been planning to attend the 2022 Hamvention and the Four Days In May (FDIM) evenings.

Hamvention weekend is one of the big highlights of my year and–until the pandemic–I hadn’t missed a single on in more than a decade.

I was really looking forward to this year if for no other reason than to connect with friends I only see at Hamvention.

My buddy Eric (WD8RIF), his son Miles (KD8KNC), and sometimes our good friend Mike (K8RAT) attend Hamvention together. We split accommodation, car pool, and fit in park activations before, during, and after. We also fit in an annual pilgrimage to the USAF museum. It’s incredibly fun.

As fun as Hamvention is–which is insanely fun–I realized that it was going to be a pricey 3-4 night excursion when I already have some pretty epic, much-anticipated travels planned this summer with my family.

Since I had literally no items on my Hamvention shopping list (Eric didn’t either) and since I wanted to funnel all of my travel monies into the amazingness that awaits us this summer, I had a hard time justifying the costs of the trip.

So I reached out to Eric who, turns out, was feeling much the same way.

We hatched an alternate plan that ended up winning us over. Continue reading Why I’m skipping Hamvention this year →

3D printed side rails and cover for the Venus SW-3B

12 Comments

Many thanks to Rick (K8BMA) who writes:

I’ve had a SW-3B for a couple of years now. Even use it in the ham shack.

I also have a KX2. From packing the KX2 around, I have noticed problems with the main tuning encoder, probably from having weight up against it. I pack it in one of the bags they sell.

Recently, I came across 3D printed end plates, cover and, STL files for the SW-3B. My son, a packaging engineer printed off a set of these parts at work for me.

Just what you need for yours. I also found a similar cover for the KX2. Next on my list.

Enjoy your posts.

73, Rick K8BMA

Thank you so much for sharing this, Rick! I believe you printed KN6EZE’s side panels and cover that are available on Thingiverse. I am definitely planning to print some of these as well. One reader noted that the encoder is a bit of a weak point on the SW-3B and it should be protected in transport if possible. 

I’ve been thinking about grabbing some KX2 side rails and Lexan cover from this company. Then again, I reckon I could also simply print some!

Thank you for the tip!

QRP POTA at Fort Dobbs: No antenna? No problem!

14 Comments

I’m a pretty organized field radio guy if I do say so myself.

In all of the hundreds of field activations I’ve attempted since the days of the National Parks On The Air (NPOTA) program, I’ve only arrived on site two or three times and discovered I was missing a key component of my field kit.  Out of those times, only once do I remember that the missing component prevented my activation (it was hard to power my radio without a battery and power cable). The other times, I was able to improvise.

As I mentioned in this two-parter series, I tend to build two different types of field kits:

  • one that’s fully self-contained (like the MTR-3B kit),
  • or one that’s modular, where component families (transceiver, antenna, power, etc) are in their own packs and can be moved from pack to pack.

I always prefer having dedicated field kits, but they’re pricey because they require a dedicated antenna, battery, radio, key/mic, earphones, pack, connectors, and sometimes even their own throw line.

I assemble modular kits around a particular radio and antenna system prior to leaving the QTH to go on an activation. I have a method for doing this which prevents me from leaving stuff behind.

Save this time…

On Thursday, April 7, 2022, before leaving the house for a quick overnight trip, I grabbed my SOTA pack and disconnected my Elecraft KX3 from the KXPA100 amp in the shack.

My pre-side rails KX3 in the shack.

My KX3 is used a lot in the shack–along with the Mission RGO One and Ten-Tec Argonaut V–it’s one of my staple rigs at the QTH. I didn’t think I would have time to complete an activation on this quick trip, but if I did, I wanted to use the KX3. I also grabbed one of my pouches that contained a 12V battery, distribution panel, and power cord.

Also inside the pack was my Elecraft KX2 kit. It was in there from a previous activation, so I just left it in the bag.

When a window of opportunity for a quick activation opened on Friday, April 8, 2022, I grabbed it. I didn’t have time to go far afield, so I chose to activate the closest park to where I was running errands that day.

Fort Dobbs State Historic Site (K-6839)

As I was driving to the site on I-40, it dawned on my that I might have forgotten to pack an antenna.

Not a good feeling, but I was only 10 minutes from the park, so there was no turning back.

You see, a couple days beforehand, I did a bit of an antenna inventory at the QTH–I took all of my antennas out of their packs, checked them over carefully for any damage or fault points and  made notes.

I normally keep a 20M EFHW antenna in my KX2 field kit, but I remembered that also I removed it during the inventory.

Once I arrived at Fort Dobbs, I opened my SOTA pack and confirmed that I had no antenna. Not a one.

I kept a clear head and realized that if I wanted to complete the activation, I needed to do one of two things:

  1. Search the car in case, somehow, I had a spare antenna floating around in there. Unlikely, but I’d feel like a fool if I aborted an activation with an antenna in the car.
  2. Go to a nearby hardware or dollar store and find some cheap wire.  The KX3 has a brilliant internal ATU to match pretty much any wire I connect to it.

So, I searched the car. Continue reading QRP POTA at Fort Dobbs: No antenna? No problem! →

Which to choose? The Venus SW-3B or the Penntek TR-35?

34 Comments

Many thanks to Pat (N0HR) who shared following question in a comment:

Thomas

I simply love your videos – both your impressions of the gear and the activations themselves. Great stuff.

I’m curious – now that you’ve played with both the SW-3B and the Penntek TR-35, which is the favorite? Seems like they’re both roughly in the same price range.

Thanks for your fantastic channel and website

73,
Pat N0HR

Thank you for the kind words, Pat, and great question! Several people have asked me variations of this very question recently.

I like both radios, so I’ll frame this in a way that might help others make a purchase decision.

Spoiler alert: You really can’t go wrong with either radio and I feel it’s more a question of operator preferences. Continue reading Which to choose? The Venus SW-3B or the Penntek TR-35? →

Dale’s 3D printed portable transceiver knee board

13 Comments

Many thanks to Dale (W7HLO) who writes:

Hello Thomas,

My wife decided this winter that she would like to see me playing radio outdoors rather than in the shack during the summer months so graciously purchased a KX2 for me for Christmas. During the long wait for it to arrive I think I read most everything on your blog about 3 times. I noticed in several of your postings that you were using a folding lap desk designed and printed by CarolAnne N0RNM.

Her design inspired me so I designed a copy cat of sorts. I wanted mine to be slightly larger so it ended up being 8.5” wide and 14” high when unfolded. 8.5 X 7 when folded up. Like CarolAnne’s it has the same recessed area to attach a sticky pad and I added cutouts in which to put a leg strap.

Now if the weather would only improve so I can go do my first SOTA and POTA activations.

If anyone would like to print one of these lap boards for themselves I have put the files up here: https://www.thingiverse.com/thing:5320260

Dale / W7HLO

Very cool, Dale! I love it. 

And, wow! Your wife purchased you a KX2 for Christmas? She’s a keeper indeed! 🙂

By the way, loads of people have asked me about the N0RNM kneeboard and I believe within the next couple of months it may be available for purchase. This would be convenient, of course, for those without a 3D printer at home.

I’ll certainly post an announcement here on QRPer.com when it available. 

Again, Dale, thank you for sharing your project!

Our radio astronomy weekend at PARI

19 Comments

Something you may not know about me: I’m a bit of a radio astronomy nut.

We’re pretty lucky here in western North Carolina to live within a reasonable drive of the Pisgah Astronomical Research Institute (PARI).

PARI started out life as a NASA tracking station during the Apollo era, then eventually became a Department of Defense facility. In the 1990s, the DOD left the site and a non-profit was formed to turn the observatory into an educational and research institute. They’ve a number of radio  telescopes and even a few optical telescopes. They’re also home to the Astronomical Photographic Data Archive and a number of other projects.

My family–including my then very young daughters–volunteered at PARI for quite a few years. We were actively involved in their Sci Girls program, I’ve given presentations about SDRs and HF at a couple of their monthly events, we volunteered during their massive solar eclipse gathering, and even hosted a weekend SWL DXpedition in 2015.

The campus is simply amazing.

Due to funding, staff and programs were downsized starting around 2019 and we lost touch during the Covid era when the campus was locked down.

This past weekend, PARI held an open house, though, and it was incredibly fun heading back to the campus and reconnecting with a few of our friends there.

My daughter and I snapped some random photos. I discovered them this morning and thought I’d share them in case there are other radio astronomy nuts out there in the QRPer community (click to enlarge these):

When my daughters were only eight years old, they were allowed to steer the 26 meter dish in the photo directly above. I wasn’t a bit jealous at all! No, not me! ?

As QRP as I am, I absolutely love gazing at these massive radio telescopes. Perhaps it’s because I know they’re working some serious weak signal DX and peering into our past to unveil some mind-blowing science!

My first POTA activation with the Mountain Topper MTR-4B V2

12 Comments

As you might have noticed from past field reports, I’m a big fan of the LnR Precision Mountain Topper MTR-3B. It’s a wee CW-only transceiver that is almost perfectly designed for summit and park activating. It’s so lightweight and compact, you barely notice it in your backpack.

Thing is, the MTR-3B is no longer produced and I’m not sure if it ever will be again, but Steve Weber (KD1JB) hasn’t stopped making iterative improvements to the Mountain Topper design and LnR hasn’t stopped producing them.

In late 2020, LnR introduced the new MTR-4B which replaced the MTR-3B and added a few extra features that many of us had been asking for including:

  • Easy access to sidetone volume control (with a dielectric screwdriver)
  • A built-in SWR meter
  • A wider voltage range and higher output power (up to 5 watts)
  • And the 80 meter band in addition to 40, 30, and 20 meters

The MTR-4B also has an attractive red gloss chassis.

And the right and left sides of the chassis even protrude a bit to better protect the front panel buttons and switches when the unit is flipped over on its face. Nice touch!

Generosity

One of the great things about being me is I am often at the receiving end of incredibly generous people who like supporting what I do.

QRPer.com is a pure labor of love and I’d do what I do without any compensation, but it’s an honor when anyone goes out of their way to thank or support me.

Seriously: the kindness I feel here restores my faith in humanity.

In January, a reader (who wishes to remain anonymous) approached me with a deal I simply couldn’t refuse. He is a very seasoned and accomplished field operator but has only recently been upping his CW game. I believe as a reward to himself for starting CW activations later this year, he told me he wished to order a new MTR-4B.

What he proposed was to purchase the radio from LnR and have it drop-shipped to me. He wanted me to have the opportunity to review this little radio and log field time with it as well. He told me I could use it for months before shipping it to him and not to worry about it getting scratched or showing other signs of field use.

Wow.

I loved this idea because, as a reviewer, it isn’t financially viable to buy each and every radio I would like to review. I do like asking manufacturers for loaner radios, but LnR is a small manufacturer and make these units to order. I know them quite well and they simply don’t have extra loaner units lying around the shop–much like new automobiles these day, each one produced is already spoken for.

I accepted his offer with gratitude. I looked forward to getting my hands on the MTR-4B!

But that wasn’t all: this kind reader has actually been sending me coffee fund contributions that will add up to half the price of a new MTR-4B should I decide to purchase and add one to my own field radio arsenal! I tried, but I couldn’t talk him out of it.

So there you go. I’m so incredibly grateful.

Delivery

As LnR Precision states on their website, there’s roughly a 6-8 week lead time on the MTR-4B. I took delivery of this unit in early March.

As with all LnR Precision products, it was packed amazingly well.

I wasn’t sure what to expect in terms of size, but the MTR-3B is only slightly bulkier than the MTR-3B (indeed, in my activation video below, I compare the two).

I love the hotrod red paint job!

This unit arrived during what turned out to be a crazy time for me–one where there was nearly a four week period with no field activations. That’s how crazy!

I did play with the MTR-4B in the shack, however, during that time and logged numerous POTA, WWFF, and SOTA activators. I even had a couple of 80 meter rag chews.

Many field ops were surprised that the MTR-4B didn’t use the forth band position for 17 or 15 meters and I tend to agree. In the field, efficient 80 meter antennas are a bit bulky for the likes of a summit activator. Then again, when in the shack or for extended camping trips? I find 80 meters a brilliant band for evening rag chews and late night DXing.

Not sure how much I’ll use 80M in the field, but I do appreciate this additional band!

Of course, the MTR-4B is built for playing radio outdoors and that’s exactly what I had in store for it on April 13, 2022. Continue reading My first POTA activation with the Mountain Topper MTR-4B V2 →
