This schematic makes no sense to me, so I had to find other examples of this circuit online along with an explanation. It seems that you have drawn a very crude type of FM receiver that is found on numerous other sites. The RF circuit comprising Q1 and Q2 form an oscillator that operates in the FM broadcast range of frequencies depending on the tuned circuit of L1 and C1. There is an error that will prevent it from functioning, however, and that is that the base of Q2 must also be connected to the left of R1 for DC bias. I understand that FM detection is achieved due to the junction capacitance of the transistors and this particular configuration. I anticipate that it is a rather poor FM demodulator, and it will have rather poor performance as a receiver, but at least the parts count is minimal. Perhaps others can chime in with more direct experience of this receiver.View attachment 117750
This is my schematic for the fm receiver and demodulator, I will edit the transmitter soon. I was also thinking of only having +5V...
this might be a job where a cheap SDR dongle would be useful... using an FM receiver, with the transmitter outside the limits of the FM band will be difficult to tell if the oscillator is working. a scanner radio might take a long time to scan through the whole range where the oscillator might be working. an SDR dongle would show you a 2Mhz chunk of spectrum at a time, meaning you can find the oscillator a lot faster.You've discovered that working at higher frequencies does tend to require some specialized test gear, but most of that can be avoided by simply doing your best to estimate values to get close enough.
