LC circuits are not that selective, a Q of a hundred might be about the best you can hope for with a -6db bandwidth of 150 Khz at 15 Mhz. So its going to need several tuned circuits well shielded from each other, but its possible.

WebThere are better designs for signal stability, lower noise, etc., but this simple oscillator will get you started. If you wish to “trim” the crystal’s frequency to an exact value, an adjustable capacitor of 50 to 100 pF in series with the crystal will do the job.

WebThe traditional filter transceiver shares one or more crystal filters between the receive and transmit modes. I wanted to avoid the compromises and complexities of filter switching, so I decided to use separate filters for each function.
