When experimenting with BPF I noticed the receiver module will receive a station transmitting at 15.4MHz when tuned to an LO of 1.03MHz. Of course only when using a well tuned BPF to get rid of the noise or transmissions at lower frequencies and at a 20 dB lower level. Seems to be the 15th harmonic. Its seems also possible to receive at the 5th harmonic of the LO
Is this to be expected?
Could that also work on higher frequencies? I did not yet try BPF above 15MHz.
Would be nice if this can work with a LO of 9.667MHz to receive 2m band
Or is a substantially reduced sensitivity to be expected?
I will give it a try anyway
