Hope audio is a bit better now. I changed some audio components (chokes) in the TX which is the reason for the test.

1500 No one - Johnny Moped - Audio is fine now.  Carrier a bit off frequency.
1503 TX Off

How much juice is coming out of your TX?

Thanks... strangely enough your signal on 7700 khz was allowing for short distance skip over the UK, while I am in Radio Merlin's skip zone on the lower 6305 khz.  Sporadic E layer? The mysteries of the ionosphere.
