"So far I have just run on 30 meters running WSPR nothing seem amiss and it seems to be a most excellent version of PowerSDR."
The your radio probably calibrated IK and there is no need to worry. If the antenna is connected and there is a nearby strong signal, it can adversely affect the RX image calibration. It is a best practice to disconnect it, but not a requirements. -Tim -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Steven L Hess Sent: Saturday, February 19, 2011 6:01 PM To: [email protected] Subject: Re: [FlexEdge] PowerSDR(TM) v2.0.19 RC1 install auto calibration on startup? How much trouble will having an Antenna connected cause? As I was un-aware I needed to disconnect the Antenna and one was connected. Just like having the radio set to 48k and running the RX image calibration and having it asking for 96k. It ran at 48k. It was not in the release notes. So far I have just run on 30 meters running WSPR nothing seem amiss and it seems to be a most excellent version of PowerSDR.
