Dear friends, I need help..
I accidentaly burned out Si5351 chip on Raduino on my BITX 40 kit TRX. So I removed Arduino and I decided to use RTC07S DDS VFO from hambuilder.com instead.
It all turned on and I set up IF to 12MHz and it is on frequency BUT there emerged two problems:
1. My BITX is on USB modulation at all times! As you know BITX 40 shoud run on LSB as it was before with Raduino DDS.. I do not know how to correct this.. I tried to switch DDS contacts opposite to get opposite V from DDS in my thinking logic but I got too low gain to hear it.. What do you suggest?
RTC07S has a LSB and USB BFO outputs, but I switched only VFO outputs to DDS on BITX as it only gives some signal.. Does BITX has BFO outputs and can I connect RTC07S to it..I dont know..
2. I get annoying buzz signall at all times in speakers, when DDS runnig.. Hopefully this is more easy to reslove, but I had no idea at the moment...
Thanks for any solution or guidance..
Vule, E78CB
