Re: Can't upload to Raduino / warranty issue
Well, I finally received a reply from hfsigs yesterday. They recommended I join this group and seek answers. Haha. I had told them in the original email I'd joined the BITX20 group on groups.io and

Re: BITX40 - convert to 20 meters
I will have a blog post up by the end of the week detailing how I turned my bitx40 into a dual bander. Right now it's 40/80 using only a second BPF, but the next mod will be to add a second LPF and

Re: Struggling with tuning clicks and birdie sounds
Simple: Minimize the LCD writes and you will be fine. I implemented a s-meter bar in a raduino like project (https://github.com/pavelmc/arduino-arcs) and oh boy... it was a mess in the RF spectrum

BITX40 - convert to 20 meters
Are there any designs out for modifying (replacing) the LPF and Bandpass Filters on the BITX40 so that it will work on 20 meters? Somewhere I saw something that said 20 Meter mods were on the way.

Re: Bitx40 Transmit Problem
You will become a guru in not time! I presume that you are reading 0.9 amps not milliamps. 900mA is too much by itself without shouting into the mic. Possible final blown, assuming you are getting

Re: Struggling with tuning clicks and birdie sounds
Hi I had also very loud buzz and tuning clicks at start. Replace your 56 ohm resistor with inductor. First inductor i tried was too small (from old computer mobo), so nothing happened. The second one

Re: VU2ESE Agc circuit
Jerry, I forgot to mention. The LDRs seen to have a peak response (to light) at around 550nm which is red LED light wavelenght, so a plain old red LED is good.

Re: VU2ESE Agc circuit
Jerry, The LDRs that you are looking for are the ones with the lowest ON (ie; lit-up bright resistance) resistance. The Bitx volume control pot is a 10k unit so if you are going to shunt the audio
