Hi John, Probably quite right about trying a lower band.
Because this is a wide bandwidth mode, I did some testing today to see how well (or not) my ICOM 756 Pro 2 passes tones at various audio frequencies and I discovered that it does not do very well with the lower tones. I moved a PSK31 tone around and compared the power output meter from around 100 Hz to 3000 Hz. The power level drops off quite a bit once you get much below 1000 Hz, although it seems to work fairly well as high as 2800 Hz. I have the rig set for the widest possible passband and using the rear DIN connector. The drop off could be due to the interface transformers, but I am not sure. Has anyone else tried determining their effective audio passband with a given rig and interface? What kind of result did you get? 73, Rick, KV9U John Bradley wrote: > > Rick you and I would be better on 40M later, VE5MU is still on Q25 > GPM is on ALE400, both on 14109 > > > > John > > VE5MU > > > > > >
