3 ms·Surely 5th is down enough dB for that not to be an issue?by setquk 8y agoSurely 5th is down enough dB for that not to be an issue?madengr 8y agoIt’s not the 5th being down. The 5th LO harmonic mixes the LTE band down to the 2m band. That’s just inherent in a Gilbert cell mixer. There is a high powered, 20 MHz wide (OFDM) signal pretty much everywhere at 715 MHz.setquk 8y agoAh gotcha. That makes sense.
