1 Watt to 9el Tonna

I'm getting some very strange decodes, so I'm not quite sure what's going on.

I'll let it run for a while, tx on 144.489,469 MHz.

Dave, G0DJA and I had a go with WSPR on 23cm today.

Dave transmitted today & I listened.

We only tried a few transmit cycles. I received good strong traces with little drift and with rx well time-synched.

On 4m, Brian's signals from Liverpool way often show doppler reflections & distortion, but decodes are reliable.

On 23cm there were similar doppler effects on Daves' signals with one trace showing significant reflections + or - 80Hz either side of the transmission. The signal also looked to be wider bandwidth, but this might be a side effect of Daves strong local signal.

None of the packets decoded.

Thanks for the suggestion of GB3RAL Graham. Unfortunately I can't hear it! I can't hear GB3MCB most of the time either.

GB3ANG 70.020 reads 70.019,89 so 110 Hz low on the dial.
GB3CFG 70.027 reads 70.027,75 so 750 Hz up on the dial.

So no consistent shift and so I don't trust the accuracy of the beacon frequencies.

I'll try 28.028,80 as my dial freq for WSPR today & see if I can spot you & Brian again.

This hasn't worked so far.

I'm pretty sure the clock is pretty well synchronised and the antenna and transverter are working pretty well. The WSPR software worked fine on 10m with sensible-looking decodes.

The problem may be that my rx frequency is off. I'm having a problem checking this as the only beacon I've heard recently is GB3ANG.

With the FT-817 rx dial freq at 28,019,160 Hz (transverted from 70MHz band), Spectran shows ANG at 650 Hz. So adding those, I get 70,019,810 Hz for ANG's freq on my rx. It's advertised as being on 70,020,000 Hz, so I'm reading 190 Hz low on the receiver. Enough of a shift to miss the WSPR band.

I have found some other beacons, but I haven't identified them.

I'll leave WSPR listening on 4m this evening (Fri-23-Jul-10), 190 Hz low and see what it finds.

I'm exploring WSPR for the first time. This is also my first attempt at a digital mode besides morse code. I'm not clear what the maximum spottable frequency is.
I'm using my old Dell lap-top running Win98SE with an FT-817.
I intend to try 6m, 4m & 2m with WSPR. I would like to try 70cm & 23cm.
