At least part of the problem is that my encode is using a Mega 2560 Arduino, which has 5 external interrupts while the Nano and Uno only have two. Near the top of my code (line 120) are: #define

So, I've been trying to get my Arduino UNO to read a rotary encoder. And have been having zero success (beyond a clean compilation). I'm using the Rotary library from?brianlow on GitHub (

Good afternoon all. I've finally got a Bitx40 on the air! Another local ham had acquired a Raduino version and decided he had too many projects to get it going so he sold it to me for just under

I checked my work and found a wrong connection on my part.? I fixed the connection and the circuit now works as described, reducing the PTT pop and noise on initial transmit. ? I did not experience

Look how I connected mine in the post before the one you posted my audio was bad till I changed the input to the AGC circuit I also dropped the audio gain of the audio amp between pins 1,8 there's a

hey, that is a very nice picture of the bitx40 break down! - f

I'm just getting started with Diptrace, so this is the best I can do right now. All of the electrolytic capacitors are 330uF 16V and all the rest are 0.1uF disk ceramics. I separated out J1's 12V in

I think that I had the VK3YE AGC installed correctly, but the audio output had the high tones clipped off, and there was a motorboating sound with the audio that I could hear. I could understand, but

Do you mean pin 7, not pin 1?

Hi, The LM386 has no inhibit control so we have to find different solutions, if possible. As Jerry reported "Dumping 12v into the bypass pin of the LM386 to quiet it down is a bit unorthodox". If you

I had a lot of fun showing off the BitX40 at this local ham fest at the WCARES table. I did it just as an excited advocate of this fun and quirky little radio, and also to rehearse for presenting it

p.s. this is NOT npota or national parks on the air

Going to head out to the park today with the Bitx and my FT-891 will be on 40m psk and ssb as well as 20m ssb and psk if I can setup the laptop. ? ?73 ?? David ??? N8DAH
