Brent’s initial impressions of the CQHAM TB-BOX

1 Comment

Many thanks to Brent (VA3YG) who writes:

Hello Thomas,

The Fedex courier just left my driveway. I ordered the CQHam TB box on Feb 29 and paid the $39 US for Expedited International shipping vs the Free Speedpack shipping from Hong Kong that promised it by June 1.  I really don’t like waiting for a parcel to arrive! Lol

I know there was some interest on your site about this product, so I thought I would write and give you some brief, first impressions.  Sadly,  I don’t have any more time to play with it until next week as I’m about to leave now to visit friends.

It arrived in 10 calendar days, well packed and everything inside survived the Fedex journey from Hong Kong to Southampton ON via Anchorage AK and Memphis TN.

No one would ever mistaken this equipment for gear made by Elecraft or Icom but it appears to work just fine. The variable capacitors are not smooth and the fit and finish is okay at best but I think, if you’re careful with it, and do your adjusting carefully, it should last you some time.

The “faux” leather case is actually quite nice and reminds me of the Yaesu FT-817 case.  As a bonus, a telescopic whip was included.

The batteries came charged and the rig showed 11.3vdc. I didn’t remove the battery tray as it didn’t want to slide out willingly and I didn’t want to force it. I’ll try that later when I have more time….

I connected my 43’ ZeroFive vertical with 30 radials to it and was able to tune from 80m right up to 10 meters with no problem.

I made a nice contact (my first phone contact in about 8 yrs) on 17 meters with a station in Biloxi.

It should be fun and it’ll give me an excuse to work the 817 again.

73 fer nw,
de Brent VA3YG

Thank you for sharing your initial impressions and the inside shots of the matching unit, Brent. We look forward to any updates you might provide as you spend more time with this field kit!

Mark discovers an affordable case for the Penntek TR-35

Many thanks to Mark (W8EWH) who writes:

Hi Thomas,

I read with interest your posts about the PENNTEK TR-35 and liked it enough to go ahead and order one for myself. I built it over a couple of weekends of occasional work, and put it on the air. I really like it.

Since I’d like to take it out on some POTA activations, I did some investigation into a case and found the following case on Amazon:

Click here to check it out on Amazon.com (affiliate link).

 

This case fits the TR-35 very nicely. See the attached photos.

There is even room for a couple of cables to be tucked away under the mesh on the lid side. The only modification I made was to add a couple of pieces of packing foam around the top and BNC side to just keep the radio from sliding around a little. But really a person preference of mine.

I thought I’d share this with you so you can share with others that have this radio and are looking for a nice hard case.

What a great tip, Mark!  Looks like it fits the TR-35 perfectly. Thank you for sharing this!

POTA RaDAR Run Final Activation: Testing the new MTR-3B field kit at Tuttle Educational State Forest

5 Comments

On January 26, 2022, I fit in multiple park activations in one day as a RaDAR (Rapid Deployment Amateur Radio) run. My hope was to activate four or five sites between 14:00 – 21:30 UTC.

Here are the field reports and videos of my first four activations:

The next park in my run (#5) was Tuttle Educational State Forest and it was the final park in this modest RaDAR run!

I packed up the gear at Johns River Game Land in a matter of three minutes, popped it all in the car, then drove 8 minutes to nearby Tuttle Educational State Forest which, at this point, almost feels like a home away from home.

Tuttle Educational State Forest (K-4861)

As I pulled into the Tuttle parking lot, I found my buddy Max (W4GZ) activating the park from his truck. It was no surprise finding Max here since I had just worked him Park-To-Park (P2P) from Johns River next door.

Max delivered some precious cargo: some more of his mom’s homemade QRP pickles!

“Them’s QRP pickles!”

Max continued to activate Tuttle from his truck while I set up my station. Continue reading POTA RaDAR Run Final Activation: Testing the new MTR-3B field kit at Tuttle Educational State Forest →

Steve is QRV in the Swiss Alps

Leave a comment

Steve (MW0SAW) and I were recently exchanging emails and he has kindly allowed me to share a few photos and details of the QRP field kit he has taken on holiday:

I’m currently in Switzerland (ski holiday)–I did bring the Venus SW-3B. I was very surprised to get 2 USA stations last weekend with 4-5 watts in the ARRL CW contest.

Only a couple of Europeans today. But it’s all fun and I did have a lovely morning ski so can’t complain lol.

My gear:

Steve
HB9/MW0SAW

Wow, Steve! I would love to be in Switzerland right about now. I’ve got a bucket list item to journey there someday (in summer months) and activate at least 10 summits. Having lived in Grenoble, the Alps always feel a bit like home.

I love how compact your setup is and obviously the K6ARK EFHW is doing the trick if you’re making contacts State side with QRP and during a contest competing with the big guns!

Hmmm…I’m now thinking I might grab a second Maxpedition Fatty Pouch. I just checked and Maxpedition still has the “buy one, get one free” deal on their website.  The link above goes to Amazon (hence the affiliate link which my site auto-converts) because pricing is typically best there, but I believe you get an even better deal at present going directly to the source; especially if one could use two pouches!

Thanks again, Steve, for sharing your field kit photos and notes!

César’s field radio kit

1 Comment

Many thanks to César (CA7OKD) who shares the following photo (click to enlarge) and description of his field radio kit:

Hi Thomas,

I share my backpack to get away anywhere, to a hill, park or beach…

    • Backpack for photographic equipment
    • Mini EF Hfkits antenna (the Balun Hfkits is missing because I lost it on a beach)
    • Coaxial M&P Hyperflex 5 with M&P connectors
    • Bottom: MFJ1899T antenna
    • Xiegu X5105, Micro, Dry Bag
    • Xiegu X6100 (perhaps the first in Chile)
    • Folding tripod stool chair

I had a very good RS-188 (McHF clone) and a uSDR; I sold them because these equipments don’t have a tuner (I like to keep the minimum).

The X5105 is a very good transceiver, the integrated tuner is wonderful.

The X6100 that fails to convince me. At least in 40 meters it is acceptable.

Greetings,
César CA7OKD

Thank you for sharing this, César! Photography backpacks in many ways are absolutely ideal for radio gear. Many allow for a great amount of flexibility in terms of adjusting internal organization. In addition, they’re very well-padded.

Interesting what you say about the X6100 compared with the X5105. I’m hoping to do a video soon focusing on the differences between these two. 

Thanks again for sharing!

Any experience using the FT-818/817 CQHAM TB-BOX?

9 Comments

Many thanks to Motters (M7TRS) who writes:

For some strange reason I stumbled across something on eBay for the FT-817/818 as I am still looking for my first HF setup.

Anyway, it’s a tuner and battery pack for a 817/818 and when I saw it I wondered if you knew about it.

[Update] And this video:

Thanks for the tip, Motters. I was not at all familiar with this pack. I do like the simplicity of the setup. 

The price is certainly right at $179 US.

There are so many FT-817/818 owners out there, I’m very curious if anyone has any experience with this particular pack and if you can report on the overall quality. Please comment!

David’s field radio kit makes use of Tom Bihn packs and pouches

10 Comments

Being the hopeless pack geek I am, when David (AG7SM) shared photos of his many Tom Bihn bags and how he packed for a recent radio outing, I asked if he’d mind if I shared them here on QRPer.com. He very kindly agreed!

The comments below are my own, but I’ve put David’s descriptions in each image caption:

Brain Bag

The Tom Bihn Brain Bag.

I’ve often considered grabbing a Tom Bihn Brain Bag in the past for one-bag travel, but frankly it’s a little roomier than I needed so overlooked it. I never thought about using it for field radio, but it makes so much sense

“The writing implements and log I’ve stuffed into the Brain Bag.”

I have used a Tom Bihn Synapse 25 for both one-bag travel and as a field radio bag.  It also has side pockets for field notes/logbooks and pens/pencils, but I think the Brain Bag accommodates them even better. Continue reading David’s field radio kit makes use of Tom Bihn packs and pouches →

My new MTR-3B Ultra-Compact Field Kit built in a Tom Bihn HLT2

12 Comments

I’m a bit obsessed with field radio kits (understatement alert).

If you don’t believe me, check out this episode of the Ham Radio Workbench podcast where they graciously allowed me to geek out about radio packs for a good two hours.

I should also note that I write, in detail, about my packing philosophy in this Anatomy of a Field Radio kit series.

There’s no cure for my pack obsession. I’m constantly in a state of assembling and testing the most efficient kits I can conjure up.

Since I rotate a fair amount of radios in my activations, the majority of my kits are modular; meaning, components like antennas, ATU’s, batteries, log/pen, and cables are packed in their own small pouches/pack. Before embarking on an activation, I simply assemble the components in a backpack along with the radio/s I might use that day. Over the years, I’ve developed a certain workflow with this process that ensures I don’t forget components or pack the wrong ones.

But by far, my favorite type of kit are those that are fully self-contained–proper grab-and-go kits that have everything I need inside to, for example, activate a summit.

Self-Contained Kits

Fully self-contained kits are reserved for the radios I use in the field most because, frankly, they’re stingy resource hogs: they  don’t share components with my other radios or kits. Continue reading My new MTR-3B Ultra-Compact Field Kit built in a Tom Bihn HLT2 →

A video tour of Scott’s Discovery TX-500 field pack

5 Comments

Many thanks to Scott (KK4Z), who shares the following comment in reply to my Discovery TX-500 field pack built around the Red Oxx Micro Manager.

Scott writes:

I finally got my bag together.

Instead of the 5.11 pack I went with my Filson Journeyman. I like the old school retro look since I am old school retro.

Here is a video on my pack using the TX-500:

I love this pack, Scott! I’ve never owned a proper waxed canvas bag, but I’ve heard so many good comments about them in terms of comfort and longevity. Like Red Oxx, the Filson brand is well known for quality products.

I like how you mounted your N0SA SOTA paddles to the clipboard so that they can be easily pivoted for transport.

I also like those POTA/QRP cheat sheets. I have those in my KX1 kit, but none of the others. I need to make some with QRP calling frequencies and the 60M channels (which I always forget in the field). Thank you for the tip!

Cutting an exercise mat to make a padded seat for the field is incredibly practical. That would also serve to pad the back of the pack and, as you point out, make sitting on wet ground much more comfortable!

At my request, Scott very kindly provided links to the gear in his field kit:

Thank you so much for sharing this, Scott!

Would you like to share a video or photo tour of your field pack?  Please contact me. I absolutely love seeing how others pack out their kits as I always learn a trick or two myself!
