QRP Head 2 Head Episode 11: Penntek TR-35 

Fantastic! KX1 light! A feature only the Baogfengs have caught onto :D

I really love my TR-35, but I just don't use it enough. I will have to take with me again on my next trip

I always enjoy the head 2 head episodes! 73, Patrick KF4LMZ

I am sure I got one of the last one’s available. I am building the kit right now along with KO4TFE. My concern is finding a lightweight case to accommodate those knobs. I like the 3D case you have for the KX1 , would be a great option for the tr-35. Great review!

Finished my TR-35 build over the long weekend(vid up later this week) Can't wait to put in on the air!

Thanks for the thourough and fair review of the TR-35. Like most of us, I have several CW field radios, and none of them are perfect. There's always a compromise somewhere. Your criticisms are on target, and are things I have noted as well. In balance, I still like the TR-35 mostlly because I find it a pleasure to use. It has great audio, both transmit and receive, and the controls are easy to use. By the way, the sidetone frequency does not bother me, in fact my DX-10 is still using default 700 hz as well. Regarding the key speed settings, John uses an analog potentiometer voltage divider to an a/d port on the processor. It could probably be calibrated by selecting some resistors to get the display to match the actual speed, but in use, I'm aware of it, and I set the speed appropriately. The keying glitches you were getting are also a result of the key speed circuitry. I've found that it's possible to set the knob "between" speed steps, and if you do, the keyer is glitchy. It's probably one of the things I least like about the radio. Thanks again for giving it a good look. It's funny that it conincided with John's retirement announcement, that wasn't known by us when we planned this radio loan. 73, Brian n1bs

I made a video on actual key speed measurements, and the TR-45L the same - actual key speed is about 10% higher than the displayed key speed.

I really hate this channel. You and your excellent reviews and conclusions. Why am I looking at the Penntek website right now? I know getting a KX1 is basically impossible.
