I have been looking all over the internet for a dds vfo that has bcd outputs that I can use to switch in band pass filters for each band
that the vfo is tuned to. I dont know how to make my own pic code to make one do what I want it to do.
I am modifying a Juma RX1 receiver. The receiver only covers 40 meters and down but I want more coverage.
I removed the original dds vfo and replaced it with one from N3ZI and it is a exact match physicaly to mount above the receiver board.
It works like a champ and covers all bands but It only has one bit that I can switch so It will only switch two band pass filters. I put a rather big band pass filter in for 20 meters from KitsAndParts and was realy surprised of how well it worked. I was also able to pick up some 15 meter signals but rather weak for an obvious reason.
I have a band pass filter kit on the way from Kess K5BCQ www.qsl.net/k5bcq/Kits/Kits.html
that I will use in the small radio, so instead of using a seperate bcd switch, I sure would like to have a VFO that has band switching output that I can use. So, any one out there have a good source to what I am looking for?
I know I can make my own, but would rather use what is out there, life is short and dont want to spend that time playing around designing something.
