My goal is to integrate a fm receiver to the stack. I have found many projects on the web using tda7000 ic for receiving broadcast fm radio. i don't know enough to know if modifying this circuit would work. Can i just adjust the LC to match for the 144.39Mhz. any help constructing a small fm receiver for that frequency would be appreciated. I also assume i will need some kind of AF amp before inputting into the argent radio shield.
TDA7000 input frequency rating is upto 110MHz only. I also doubt the VFO would be stable enough for
narrowband FM and you have no solution for SSB with that chip AFAICT.
Thanks I know cheap radios are out there but it’s not about the money. Looking to learn and I only need fm receive capability for this project. Found documentation on mc3363 that looks like it could be possible???
Looks pretty capable, but all the support components like tuned circuits and filters and crystals make for
a complex build that requires RF alignment with suitable testgear - its not an out-of-the-box solution
unless someone already does a 2m module using it.
