I'm new with the SDR and a think there is a problem.
Equipment: SDR-100 + ATU + 100W PA + 2m XVTR
When i check the receive frequency it changes from time to time. The difference to a reference transceiver is up to -120kHz and it's not possible to calibrate over this wide range.
Please have anyone an idea what's going wrong????
