My only comment is that the ones I have heard seem to consistently drift 1 to 2 Hz during a 2 minute WSPR transmission. So if you wanted to use one for something like slow DFCW on LF, you would proba

Of course it could be the transceiver drifting, but curiously all I have been aware of so far moved in the same direction and approximately the same amount... who knows. Paul

Saw the writeup in QST and immediately noticed the receive two-tone, third-order IMD at 2 kHz spacing is 60 dB and at 75 kHz spacing is only 74 dB! Good luck with that if you've got strong signals at

Ouch! Having operated on 160m and the HF bands for several years using a receiver that comes in at about -63 dB on 2 kHz spacing third-order IMD I would never again buy something with that kind of re

Those IMD figures don't in themselves say enough to say whether it is good or bad. Firstly, that quoted paragraph doesn't give the input levels at which IMPs were 60 [75dB] down.   It is more usual t

Andy Maybe I can shed further light on my comments ... The ARRL receiver measurement system was developed by Wes Hayward of Tektronics back in the mid 70's and has been used with minor changes since.

Hello Andy, -125MDS means that noise is at -125dBm,not at -128dBm. You feed a signal of a sig gen into the receiver and adjust its level until a RMS AF voltmeter at the receiver's AF output shows an
