Hi Alan,I've seen some drift that was -3 or -4. Anything to be concerned about?Stan,
It looks like the IC-7300 does drift some. I tried with my TS-590SG and
the drift shows as 0 on almost every station that reported hearing me.
The TS-590SG does have the optional TCXO.
I've thought about making a WSPR transmitter using an Arduino UNO with a
GPS module for the time and an AD9850 DDS. Something like this

doesn't look quite right though. Will have to see if it works when I get
the Skylab GPS module.
