Hi All,

I have been reviewing decoding issues threads here as I just completed my qcx transceiver? and installed? firmware 1.0.0d.? The little rig checks out fine except for WSPR beacon mode.

Basically,I am seeing issues with stations not being able to decode? beacon frames.? Only a couple of stations can decode the signal when I've tested on air.? When using my Ultimate 3 WSPR transmitter (300mw), I get over a dozen stations that are decoding.

I set up a local receiver and attempted to decode the WSPR signal from the qcx xcvr.? I had very little luck and only able to decode once or twice.? I then connected the GPS module to see if it changed the symptoms which it did not.

I decided to look at the signals with "Argo" to see how the shifts look, see below for results.?

What controls WSPR shifts?? I assume that shift control is in software and hardware does not come into play, is that a correct assumption? Has anyone else looked at the WSPR signals??
