Onderwerp: LF: Re: Testing WSPR-15 on 630m
Oh, the PA seems to be damaged. This may come from the rain which
detunes the antenna and rises the PA losses. Furthermore it is a 15
minute "key-down" transmission and some of the thermal time constants
seem to be well below 15 minutes ;-)
I will have to repair the PA. Back on air in 1 hour or so.
