All: Next week I'm going to propose a club build of the BITX40. However, I plan on using the Mega2560 Pro Mini and a TFT display. I've looked on the site and it appears that just buying the board at

Hello Don, By checking that the audio amplifier is working you have already started back tracking the circuit. Have you got a RF probe or oscilloscope etc. for RF voltage measurements ? If not make a

Nice and inspiring video & I liked the Heil PR-0 thanks

All: I took the Raduino source code and tried to compile it under the Arduino IDE 1.8.1 and it would not compile. I traced it to the fact that I was using a newer version of the Si5351 library. I knew

Do you have any photos of the connectors you're talking about? Roy WA0YMH

Hi Jerry That's good to know that others reached the same conclusions that I did. In the QRP Labs kits I am using only 32-bit arithmetic for all the Si5351A computations. There is one place where

AF6TC tonight with analog BitX40. TX to CA. Always a thrill but the ears on the other end are a very important part. 72, Bob KI0G
