The one looks to be the amplifier and filter module to me. Matthew Pitts N8OHU -- Sent from my Android device with K-9 Mail. Please excuse my brevity.

Thanks Curt. Okay that’s the filter I was going to get as well. I also saw the blog where the blog suggested to increase bias voltage. I am also waiting for a similar sized heatsink too, next will

I took a look at it.? Simple, straight-forward, and most of the features I consider critical - you can do a lot with that.? If the battery test puts a small load on the battery while testing, that's

Laurent my best guess is the BFO calibration is off - shifting you passband to the high side.? possibly you might hear similar distortion on receive? try the instructions here, as required Micro-BITX

Sorry, I'll take it back. I just read that you wrote WSJTSX worked and checked the source code 38400 is correct after all. What version of flrig do you use? I mean when was it released? I think I

Hi Vic, I think you are using the wrong baud rate. Try changing to 19200 Baud - that should do the trick. The correct speed is hardwired within? KD8CECs firmware. You can change it of course, but

Hi there uBitx owners, today a ham confirmed me that my modulation was only in the treble part of the audio spectrum: no bass and (that the most annoying) no medium frequencies to hear... I wonder?

Now the one wants $140.xx for it, while the one in french is cheaper. A big difference, yes? Wayne WA2YNE

Hi Joe, The filter set that Oliver has listed above is the one that I am using. ?They used to be $50 or so which in my opinion was overpriced especially compared to what they are now. ?I mounted

Amateur radio kits for BITX units parts https://amateurradiokits.in/store/components-for-kits/ The parts are for a BITX20, but with modification can be for any band. They also sell some bare boards,

Looking at two pictures, it looks to be a NANO with a TFT, maybe touch screen? Interesting, being as I just received two NANOs, though planned to use one to make a clone of a raduino. Maybe both, in

Thanks so much for the quick replies! And thanks for the home-brew links. I'll read through those in the next couple of days. Ugly construction would be just as fun, so I'll probably go that route. I

Mitch I think that this <https://www.qrpkits.com/bitx20a.html> is the last thru-hole kit of a BITX transceiver. It should be possible to add the Arduino, Si5351a, and LCD to one of these. In earlier

Really, the large size (1206) SMD parts are not that bad to use even for a pair of 76 year old eyes, plus resistors and caps are really much less expensive than through-hole. You could also shrink the

I would LOVE a through-hole pcb + bag of parts version of the latest uBITX (how I miss the old Heathkit days...)! Is there any possibility of such a thing? All I can find are sold-out kits of older

I'd take one when they are ready to go... TNX Kris - K2FIN

I am interested too. Policarpo VA3AGP
