hi Telamon:
how would you characterize these RX340 specs?
IP3: 5-kHz -53 dBm, 20-kHz +4 dBm
The 5 KHz number is not very good. The 20 KHz number is not bad. In
practice you might think I would have a problem listening to a weak
station with a strong station on the next channel over but I haven't
noticed it.
phase noise: -113 dBc/Hz
It would be nice if it was -120 down but it appears to be low enough
because the receiver noise floor can be 1uV.
ultimate rejection: 70 dB
It is supposed to be at least 70 dB but depending on how you use the
radio it is actually much greater so the ultimate selectivity is better
than this number makes it look.
