Yes Frank, See if the spurs change with bias, be gentle with the adjustment and keep watching the ammeter! Raj

At K1 pin 12 add two diodes parallel but opposite polarity to ground. You can do that at K3 pin 14 alternatively. Raj

ROTFL! Doc Jack you are a gem, I have your book too! Raj, vu2zap

It should work, I have not tried it.. sitting on the farm with some coffee buyers from Holy Island in UK.. Farhan has made provision for separate supply for the final. Raj

Jeff, Doug is probably correct. There is no real programming needed. You will just be uploading a new program ("Sketch") into the NANO. The real programming has already been done. This is about the

As long as the RFI from the guy around the block is off I will be on this weekend. Always up for a QSO during the week as well.

Several folks have joined the Discord chat https://discord.gg/CrHvWFc. Perhaps we can use this for time and frequency coordination for the QSO night?

Not sure if I'll be able to get on at 3PM EST (2000UTC) this week, bit I'll try. -- John - WA2FZW

Jeffrey, When you use the word programming do you mean writing and or modifying code or are you using the word programming to mean loading a sketch onto the arduino?

Thank You Marco, I will read the Wiki tomorrow morning. My old eyes are getting tired tonight. I appreciate your suggestions and guidance on programing. Lots to learn! 73 de Jeff K9JP

I may be wrong, but Q90 is a transmit stage and is isolated from the rx path by C80. ?The ring diode mixer (D1 & D2) essentially are reverse diode pair acrosd the input to T2 secondary offering a

You can also find a wealth of info in the WIKI: /g/BITX20/wiki/Raduino-Topics There is a topic on installing the IDE and the libraries. Good luck, Marco - KG5PRT
