my audio

One of my main interests in ham radio is to get the best audio out of the 3khz bandwidth and a very clean tx signal .
First of all, many thanks to my friends Andrea (9H1TT) and Peter (HB9UQX), which are supporting me with endless patience 🙂

For all ham’s which are using one of the big Acom’s or a Alpin 200, check how to disable EBS (electronic bias system). Maybe it is affecting the modulation, so best to turn it off.
