Hi,
Just finished my Ultimate3 transmitter, using it in 40 meters frequency 7040180.
The frequency is derived from a GPS receiver. Looks like I am within +-1Hz
I am looking for other stations on 40 meter with high accuracy.
the ones I know are :
DL1FX tx only linked to DCF77 on 7040123
K9AN rx+tx with GPSDO tx on 7040170
are there any other stations on 40 meters with high frequency accuracy?
