This is a short review of the new Penntek TR-45L 5-band, 5-watt, CW QRP transceiver produced by WA3RNC. We take a look at the physical characteristics, and the completely menu-less operation of the rig. Such a fun transceiver to operate! Production expected to begin for factory wired/aligned units in early 2023, to be followed by kit availability shortly after that. For more information, visit the product webpage:

This is hitting the hearts and minds of all the analog guys just with a touch of spice of digital. The tactile feel of knobs and switches, and for those who love the ability to fine tune, and adjust to galore .

The TR-45 Lite is beautiful. Love the look and that it's not menu driven; love the meter, the 16X2 display, and the layout of knobs and switches. Brings back the joy of being a novice licensed ham back in the 60's.

Looking at that radio makes me want to smile. I suspect what you have is a prototype. It looks like something a ham would build out of old parts from the scrap bin. The meter looks like it came off an R390. My guess this is what the designer was after. A retro garage look radio, but still, great performance.

I love my KX2 and KX3, they aren’t going anywhere, but it’s always nice to have another. And the fact that there are separate key and paddle jacks is huge, I am so spoiled with my KX2 and KX3. I usually run a paddle and a straight key /p when activating a summit or park, the key let’s me slow down and or make an SKCC call. Thanks for the video. W1ND

Thank you for an in depth review! The rig looks nice and sounds nice as well. Although, my love is still QCX mini, and taking into account price tag you can build 5 of one band QCX mini's and will still have a budget for a key or another band. I understand that the QRP is a different world, but the reviewed rig assembled is almost the same price as Icom IC-718, if I am not mistaken. I would choose 718 + extra CW filter. But it is only me.

I have been trying to learn CW on and off for decades but always failed. At some point I feel like I almost might be ready to try on the air but then I get so nervous that everything falls apart and I lose track. Then years pass until I get reminded of how much fun it seems to be to be proficient in it, and I restart practicing. It seems like a continuous wave. I'm sure I would be really bad in the beginning, and it seems really intimidating to start a qso with someone who would probably just get annoyed by my mistakes.
@w2aew
@w2aew Год назад
I felt the same way. I learned CW over 40 years ago the *wrong* way (at very slow speed and memorizing dit-dah patterns, which forces a lookup table approach). About 25 years ago, I re-entereed CW and started to break the mental translation habit and was able to upgrade my license. Then, ignored CW for another 20 years or so. Jumped back in a few years ago. With regular practice (and encouragement from fellow hams), gradually got better and more confidence. I'm still only about 15-18 wpm, but this is plenty fast for most. And, CW is full of good/kind operators that are willing to slow down or space things out to help - so don't worry about making mistakes - we all do! And, it's all fine....

We were all new once. I like chatting with new CW folks. What broke the code for me was meeting a friend on air everyday. About 3-4 months for 1/2 hour. That was enough time for 3-4 exchanges of info. I got close to head copy by the time life got too busy and I was too lazy to get up in the am. . .
@cwqrpportable
@cwqrpportable Год назад
Don’t give up. Try to find someone you can hook up with on a regular basis to exchange very slow CW. I was fortunate to find such a fellow ham; he was patient and dedicated. After a few months of regular Qso’s, my confidence increased as did my cw proficiency. In my 35 years as a ham, I’ve only ever heard one fellow ham complain about a newbie’s cw. The vast majority of hams are patient. You can do it. I relearned CW 20 yrs ago and have never looked back. I’m now 95% CW. Good luck!
@wtmayhew
@wtmayhew Год назад
The first transceiver I had was a used Heathkit HW-16 CW transceiver in 1974. There is no motivator to learning operate CW as when CW is your only option for getting on the air. I’m rusty on CW now, but it doesn’t take too long to get back in the groove though I may not be too fast. I still remember my first QSO when someone a couple of towns over answered my CQ on 40m. The other operator realized I was a novice (literally the license I had) and was quite accommodating. This Penntek looks like a nice little transceiver, not complicated to operate, no need to dig through menus to make adjustments. Quite often the qualitative matters more than the quantitative. The Penntek looks like a great option for Parks on the Air or similar portable work. If you’ve never done CW work, you’ll be surprised at how well you can get out with even just a few Watts into a reasonable antenna. The other advantage is that CW with the narrow filter in is much less fatiguing for listening because there is not constant audio hash blasting your ears.
