I received my Penntek TR-45L on Friday.
Just for your info: if anyone wishes to adjust the sidetone level there is a way to do that:
TR-45L Internal Sidetone Adjustment
The sidetone level adjustment can be accessed by removing the front panel assembly from the rear case.
First, remove the six screws that secure the panel to the rear case half. Separate the panel assembly and lay it face down on the table. Be careful with the interconnecting cables.
While operating the unit, adjust the sidetone level pot (circled in red) for the level of your liking. Reassemble the panel to the case rear. You may need to squeeze hard on the corners to make the panel fit. Be careful with the dress of the internal cables.
Thank you so much for sharing this, David. This is a very simple procedure and shows, also, how WA3RNC designed the boards so that the pot is accessible without having to pull apart the two main boards!
Because I receive so many tips from readers here on QRPer, I wanted way to share them in a concise newsletter format. To that end, welcome to QRPer Notes, a collection of links to interesting stories and tips making waves in the world of radio!

Check out this short article by John (AE5X) where he uses a CW Flea transmitter and Belka-DX receiver for a QRPp POTA activation. I love what John’s done here and I think I may have to give the CW Flea a go too someday.
Here’s the video that accompanies his blog post:
We need to do a little time-travel in this short field report…
In 2022, I accumulated so many activation videos that I have a small backlog and some that got lost in the shuffle. The following activation report is one that I meant to post in November, but it got lost in the shuffle.
So let’s time-travel…
On October 20, 2022, I pulled into Tuttle Educational State Forest to enjoy quick a POTA activation with my Penntek TR-45L.
I remember now that I wanted to hold off publishing this video until John (WA3RNC) at Penntek had time to ship the bulk of the radios from his first production run of fifty units. Demand has been very high for this sweet rig and for good reason: it performs brilliantly, is fun to use, sports amazing audio, and (with its Apolloesque design) strikes the right nostalgia chord for many of us.

I had a very short window to do this activation–a maximum of 45 minutes or so. You see, I still had a good 1.5 hour drive back to the QTH and needed to pop by the post office to pick up parcels before they closed at 17:00 local.
I had planned to pair the TR-45L with my PackTenna random wire antenna and use the 45L’s Z-Match tuner, but I discovered I’d packed the PackTenna 20M EFHW instead.
No problem there as the PackTenna 20M EFHW is very efficient and (of course) resonant on 20 meters, so I needed to make sure the TR-45L’s ATU was bypassed before hopping on the air! Continue reading Pairing the Penntek TR-45L and PackTenna 20M EFHW for a Quickie POTA Activation
Many thanks to Ron (W6AZ) who notes that W2AEW has posted a review of the TR-45-L on his excellent YouTube channel:
I meant to post this video earlier when I saw that Alan published it, but forgot. Thanks for the reminder, Ron!

As I’ve mentioned in the past, I feel pretty lucky to live in an area that is flush with POTA sites. It’s not that we have numerous individual parks, but the parks we do have encompass massive portions of the area.
One park, in particular, that literally runs around and through Asheville, NC, is the Blue Ridge Parkway. When I’m in town and have a few free minutes, it’s quite easy to hit the BRP; it’s never far away. I can set up along the parkway pretty much anywhere, or go to the Visitor’s Center or Folk Art Center if I want to operate from a picnic table. In addition, the Mountains To Sea Trail runs along large portions of the parkway, so it’s very easy to hit it as well.
On Wednesday, September 28, 2022, I took my daughters to a class and had the better part of an hour to play radio. The BRP’s Folk Art Center was only a 10 minute drive from their class, so I made a beeline for the site as soon as I dropped them off.
I had the amazing Penntek TR-45L packed in my car, and decided to pair it with my Tufteln End-Fed Random Wire antenna.
