Re: LF: TXing 2200m WSPR

Hi Paul,

Congrats to your first transmission!

How do you couple the PA output to the antenna? Are you using an 
isolating ferrite transformer? Without knowing your problem in detail, 
this is the first thing i would suggest to use! Separate the antenna 
earth from the shack earth by such a transformer.
