POTA Field Report: Testing my CP Gear Tactical Aircrew/Pubs Bag with FT-817ND and Armoloq TPA-817 Pack Frame

7 Comments

Last year, during a Black Friday sale, I took a calculated risk and purchased a bag I hoped would accommodate my Yaesu FT-817ND that has been outfitted with an Armoloq TPA-817 Pack Frame.

CP Gear Tactical Aircrew/Pubs Bag

Rod (VA3ON) first introduced me to CP Gear Tactical–a  military pack manufacturer based in New Brunswick, Canada.

I’d had their their Aircrew/Pubs Bag with Padded Tablet Pocket on my wish list since the Ham Radio Workbench podcast episode where we talked about backpacks and pouches. CP Gear Tactical manufactures a wide variety of gear primarily for the Canadian military market. Everything is made either in Canada or the US (or both).

I contacted CP Gear Tactical shortly after outfitting my FT-817 with the TPA-817 pack frame. I measured the frame carefully and asked if the interior padded pocket (which is actually designed to hold a tablet–might fit my radio.

I never heard back from them. I could have called them, but on Black Friday, when it was on sale for 20% off and free shipping, I decided to throw caution to the wind and simply purchase it. My total price in USD was something like $62 shipped.

As soon as I opened the CP Gear pack, the first thing I did was check to see if the FT-817 with pack frame would fit in the interior pocket.

Much to my surprise, it fit it perfectly!

Indeed, it’s as if the pocket were specifically designed to accommodate the FT-817ND/TPA-817 combo.

Even the middle Velcro strap fits precisely in the middle of the radio between the pack frame side extensions. The strap holds the rig securely; once, I accidentally fumbled while holding the bag and even though it was upside down, the FT-817 remained securely inside. The strap held it in place.

The bag has loads of room inside. In fact, you can very easily transform it into a fully self-contained field radio kit.

I actually give a small tour of this pack in my activation video below, so if you’d like to see some of the exterior pockets, I would encourage you to check it out!

Zebulon B. Vance Birthplace (K-6856)

On Tuesday, April 11, 2023, I once again popped by the Vance Birthplace for a leisurely POTA activation–I thought this activation, in particular, would be a good one to test my new Aircrew/Pubs bag!

Testing my new Headrest QRP POTA Field Kit!

8 Comments

I love field radio kits.

If you’ve read my “Anatomy of a Field Kit” series, you’ve likely gathered that field kits are a bit of an obsession. [Yeah, understatement alert!]

My field kits roughly fall into two main categories: modular and fully self-contained. My modular kits are ones where components like the battery, antenna, throw line, key, and radio are in separate pouches and can easily be combined to make a complete station before I leave for an activation.

My fully self-contained kits are ones that quite literally have everything needed to perform a park or summit activation in one pouch or box. A good example that I’ve documented here is my MTR-3B field kit.

For more on this, again, check out my “Anatomy of a Field Kit” series.

Vehicle kit

If you’re a devoted park and/or summit activator, I think it’s important to keep a dedicated kit kit in your car at all times. Why?

  • It’s ready to grab for impromptu activations
  • It’s handy in case of road-side emergencies in remote areas
  • It’s always  accessible to demonstrate amateur radio to those who are curious
  • It’s always always there for those times when you hadn’t planned to play radio, but the opportunity presents itself

I always have a full radio kit in my Subaru and over the years, I’ve changed and adapted it. For the most part, though, it’s been located in the trunk/boot and lives with anything and everything else I keep back there. Sometimes, it’s in the way when we need to fill that trunk space with family items for a trip or when we’re hauling things around town. Other times, it’s floating/sliding around freely in the back.

On long family trips, I’ve been known to store radios under the floor, but it’s a true hassle to remove them because I have to remove anything in the trunk before lifting the floor.

Contraband I hid in the car during our two month Canada trip last year.

I’ve always wanted a way to store my kit in the car in a dedicated space. In the past, I’ve tried to make a kit that could fit under the driver’s seat–thinking that might be ideal–but there’s very little clearance under it and it’s difficult to remove.

Enter the BROG Headrest Pouch Kit

Before I placed my initial order for the Blue Ridge Overland Gear (BROG) Gadget Bag, I checked out other items on their website. One that immediately caught my attention was their Headrest Kit.

It consists of a Velcro panel that fits around a vehicle headrest and a pouch (or pouches) attach to it.

BROG caters to Overlanders and vehicle storage/organization is huge in that community. The headrest kit makes a lot of sense: it’s using space that’s accessible, doesn’t interfere with any passengers, is off the floor, and is otherwise underutilized!

The big questions, of course:

  1. would the pouch offer enough space to store an entire radio kit,
  2. and would the kit weight too much for the Velcro back to hold it in place?

I asked for the Headrest Pouch Kit ($47.99) to be sent with my Gadget Bag order.

BTW: Big thanks to BROG for giving me flexibility with this order. Since I had no experience with their gear, I asked that they send me a list of items and allow me to evaluate them, then pay (full price) for what I decided to keep. 

Would it work?

I knew I’d need to store a very small transceiver in this dedicated pack. A few could potentially fit the bill–namely the:

  • Mountain Topper MTR-3B
  • Venus SW-3B
  • QCX-Mini
  • TEN-TEC R4020

I eliminated the QCX-Mini from this list because it’s mono band (mine is set for 20M) plus, I really love the field kit I already designed for it. Same for the MTR-3B–the kit I built for it is now time-tested and I love it as-is. The R4020, while quite compact, is the largest in this group of wee rigs.

Coax cables I used for SOTA/POTA – A horror story

31 Comments

by Thomas (DM1TBE)

I think every portable operator thinks about their coax cables and how to use more light and flexible types. During the last few activations, I have switched from my rigid Aircell 5 to the lightweight and flexible RG316. I have bought a couple of different lengths, mainly from Chinese online sellers at AliExpress.

However, I had some hard to define issues like the vague feeling that I am not getting out as good as I should, or a changing SWR during an activation. So I thought I should check my cables before looking at other parts of my equipment.

My professional and educational background does not have anything to do with electronics, and I don’t have the equipment to measure the cable loss directly. But my goal was to check if the cables were faulty, not to measure the exact attenuation.

I have an SWR and Power meter from DJ9PK as per image below. It can measure PEP and has, according to the seller, an accuracy of +/-4 percent.   You can find more details about it here in German or here in English (Google / auto translated).

My KX3 with a CW paddle served as signal source. As large differences are easier to spot than smaller, I switched to the 10-meter band as the HF band with the highest attenuation.

I then measured a short cable with a very low loss, a 1 m / 3.3 ft RG213, which should have an attenuation of less than 0.1dB (excluding plugs).

I simply checked how much power came out at the other end of the cable. That value I have used as reference. This cable (and all others) was plugged directly between the KX3 and the power meter, no ATU involved anywhere. The power meter was set to measure PEP.

Field Report: BROG Gadget Bag Tour, New Anker Speaker, & Pairing the KX3 w/the MC-750 for Serious QRP POTA Fun!

29 Comments

On Tuesday, March 28, 2023, I packed my Elecraft KX3 and took it to the Zebulon Vance Historic Birthplace (K-6856) for a nice, relaxing, early afternoon POTA activation!

It had been a few months since I’d taken the KX3 to the field and it really does deserve some outdoor time because…well…I still think it’s one of the best HF field radios on the market.

I’m spoiled, though, because I also own a KX2 and it does 80% of what the KX3 does, is much smaller, and sports a very long-lasting internal battery. Because of this, my KX2 gets way more field time and the KX3–hooked up to a KXPA100–is my main radio in the shack.

When I make an activation video in the field, I like using a speaker rather than recording from the line out of the radio. Besides the extra post-processing, sometimes the line-out audio from left and right channels are out of phase from each other and end up cancelling each other out in YouTube videos if listening in mono. I recently learned how to fix this, but I find the whole process just adds *that* much more time to post-processing and I’m always pressed for time.

The Elecraft KX3 has a built-in speaker, but it’s pretty anemic. I almost always pair the KX3 with an external speaker to amplify the otherwise excellent KX3 audio for my activation videos.

On this particular day, I had a new speaker to try as well: an Anker Soundcore Mini. I purchased this speaker on the same day I posted Mike’s speaker search and review of the Soundcore Mini. Although I have a Sony SRS-XB12 portable speaker and love it, they’re no longer produced and the battery life isn’t quite as good as the Soundcore Mini (Anker states up to 15 hours per full charge).

This activation would give me an opportunity to really test the Anker Soundcore Mini in the field. In the end, it did a brilliant job.

I should note that I also brought my Blue Ridge Overland Gadget Bag (see above) to the field that day, so I include a little tour and overview of this pack in my activation video.

I did recently post a review of the BROG Gadget Bag here on QRPer as well.

Zebulon B. Vance Birthplace (K-6856)

As I mention in my activation videos, Vance is a small park and, unless you plan to operate from your car, there’s really only one good site to set up: in the picnic shelter. Thing is, if a school, club, or civic group is scheduled to meet that day, the picnic shelter will almost certainly be reserved for them.

Each time I activate Vance, I ask the park staff in advance if the picnic shelter is reserved and if it’s okay if I perform the activation. Fortunately, the shelter is reserved only about 20% of the time. On days when it’s reserved, I simply activate elsewhere.

On the 28th, I had the site to myself and the staff encouraged me to activate as long as I wanted to. Continue reading Field Report: BROG Gadget Bag Tour, New Anker Speaker, & Pairing the KX3 w/the MC-750 for Serious QRP POTA Fun! →

Scott builds a mobile desk for HF park-roving

Many thanks to Scott (KK4Z) who shares the following post from his blog KK4Z.com:

Necessity is the mother of invention

by Scott (KK4Z)

Plato’s Republic he said that *our need will be the real creator* or the proverb as we know it today *necessity is the mother of invention*.  Recently, my friend Thomas K4SWL acquired a Yaesu FT-891.  During his YouTube video, he expounded on how much fun he had with it. It did indeed look like fun. During this time I was pondering about doing more day activations instead of overnights.  With the cost of everything still climbing, the need to conserve becomes apparent.  I thought an FT-891 might really be a great radio for these day activations. Then reality set in.

I already have a number of projects I am working on and misc things like maybe having to replace my old 33′ push-up pole, it was not in the stars nor was there a twinkle in my wife’s eye when I mentioned it. In reality, the IC-7300 is a great radio and does everything I need to do especially in the field. I don’t need another radio, I have three 100 watt radios and three QRP radios. I still wanted an easy setup for these one-day activations. I want to drive to a park, set up in a few minutes, operate, tear-down in a couple of minutes, and head for home or another park. I also wanted to make my day activations park ranger friendly. To me, that means trying to be inconspicuous.

I have two projects planned. The first is a desk for my truck. I am making a desk to sit over the center console and front passenger seat big enough to hold my IC-7300, a laptop and a CW paddle. My plan is to secure the desk to the truck and the radio to the desk. I also wanted to make this as cheaply as possible. I used stuff I had on the property such as a half sheet of plywood and some construction lumber. The only things I had to buy were some screws and eye-bolts, about 14 dollars worth.


The plywood was cut to 24 x 38.5 inches. The length covers the center console and front seat while still allowing me to get to the heat/AC controls. I gave the corners a generous radius and I broke the edges with a router. On the underside, I used a 2 x 12 to make a spacer for the center console where the cup holder is and a leg for the other side over the passenger seat. The spacer is glued and screwed to the desktop but the leg is not attached. This is to make it easier to store. I made a socket for the leg using 2 x 2’s. It’s probably easier to look at a picture than me to try to explain. I added eye rings to the rear of the desk and use a bungee cord to secure the desk to the passenger seat. The only other thing I did, sprayed the top with polyurethane. Note. I am not a carpenter or cabinet maker. I use rough hand tools to get the job done and I am often making do with what’s on hand or what’s the cheapest way to do it.

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.

The Gabil 7350T Compact Antenna and Gabil GRA-ULT01 MK2 tripod

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.

Thanks to all the chasers.

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

11 Comments

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.

Fort Dobbs State Historic Site (K-6839)

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)

6 Comments


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

14 Comments

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

23 Comments

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!
