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

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!

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!
