Hi Peter and all,

I suggested the Spectrum Manager at AIR to set a more robust protection level (if possible with what they are doing) but got only an answer with a request for my full address (given to them a couple of times) to send me a QSL card. A QSL card is very welcome, but I think, especially as they call it a test transmission, they should then experiment a little with the settings.

But the propagation was much better last night compared to now. Only 17.5% decoded audio and the SNR was 18.7 dB on average. It would have been about 4-6 dB better if I had remembered to set the AGC to "slow". The Channel Impulse Response was pretty awful this evening adding to the bad result.
