Has anyone any idea as to what might be causing this ? Not all signals are decoding.
50 Hz hum on the audio?
Yup, you've got some signal repeating at what looks very, very close to a 50Hz interval. Given your G0 call prefix the most likely culprit is strong 50Hz hum on your audio.
How are you coupling audio into your computer for digital decoding? Are you using a rig audio to PC interface with transformer isolation?
Thanks to you both for your input. I'm using a SignaLink USB interface. Have increased RF and keeping RX audio at 40%. This seems to have resolved the problem.
