Hoping to do some testing this evening at 477.695 kHz after a rebuild of the TX. A bigger PSU gives me around 150W DC input so that should be good for a few extra dB. Hoping to see if the anomaly bet

Some interruptions to the signal, a problem with the tx and I've had to drop down to a lower power. Next complete message starts 20:00. -- Paul Nicholson --

Thanks Markus, much appreciated. A good decode of a weak signal. Maybe tomorrow I'll try again with higher power so that anomaly will show up more clearly if still present. PA was misbehaving tonight

Hi Markus, Thank-you for taking a look. The propagation indicies, DST, carrier frequency and SWR all look good so I wonder what the problem is. 73 Joe VO1NA Sorry Joe, not the faintest trace here on

Hello Joe, We are stuck in the aftermath of another geomagnetic storm and T/A propagation is rather poor. Nonetheless, your signal made it. See attachment. There is also another signal at 22:45 UTC t

Hello Joe, Propagation was worse at the start but picked up after 04.30 UTC for a short time. At its strongest, the carrier was 8 dB above the band noise in a 10 Hz bandwidth and easy to copy by ear.
