Mr. Farhan, I had a moment where the IF gain was so forceful that the waterfall had turned entirely red; this was during that period when the raspberry pi digital board would shut down when transmitti

I got one for a BITX40 from HF Signals last year and I believe they are still listed. I was told to let them know it was for a BITX40. I just looked and they are listed at $45. 73, Justin B KI5GKD

Mark, You are on the right track. All you are trying to do is hack the code so the si5351 VFO mimics what the old analog VFO does. You could get a generic VFO, perhaps from QRP Labs, and ask it to tun

Hi all (and particularly Allard Munters PE1NWL if you are monitoring!) I would like to add a Raduino to my original BITX20a (built from the QRPkits.com kit). I have obtained a PCB for the original BIT

I have made a video showcasing the easy bitx through hole and smt kit . Hope you would like building one . Link below for my you tube video https://youtu.be/xDZ6nd90W44 Please comment and subscribe to

Many thanks Curt - as you say, going back to first principles provided the answer! I’m gonna try using the LC VFO as a first outing, but if I find it a struggle to operate may replace with a PLL. To d

Correction to my message above - low end VFO frequency is currently around 3.087MHz - missed a zero out on my original post - apologies!

We have uploaded the Easy Bitx Version 2 docs. The coils data is the same for both versions easy bitx version 1 and version 2. The easy bitx version 2 audio amp is mounted on the front panel board wit

Hi Kelly Glad you got working to your satisfaction. A 386 might only put out a half of a watt. I have the bfo set for the sound that I hear the best. It isn't the most even type of sound level but it

#bitx20

Kelly, Yeah, you are right about a powered speaker as I have found that the stock volume is a bit lacking and if turned all the way up starts either clipping or distorting. 73, Justin KI5GKD

Evan, thanks again!! I appreciate the help! Kelly KD5AJ

Yes i understand the settings saved pertain only to that board. I will get back with my results later today. i will save a screen shot on the 7300 or my other sdr's. Will let you know Very appreciativ

Hmm, Sounds like something was wrong with the board's original mic amp circuit. I can't imagine they are all like that. Good you got it fixed, but it would be interesting to know what the original pro

I think you missed what the man is saying. He's working with the original bitx20 kit that was around before the Raduino and uses an FLL board with a PIC and LCD display. The FLL also supplies stabiliz

That did the trick! Just made my first contact on FT8 with the uBITX! Thank you.

Gary, Is it possible to remove the Raduino and display from the case and connect to the USB port on your computer without the mainboard? The Raduino should powerup and the display should show the norm

I've RFed an Arduino Uno in the past and scrambled it. Had to reprogram it and it was fine afterward. Give it a try rewriting it. When I RFed the Uno some of the functions were still working, just not
