LF, Hello!

Thanks for reporting me too Mal!

The new message includes full callsign in QRSS3 to enable ID reception for t=
hose
seeing my dashes. Will run like this if the PSU doesn't overheat.

I did not expect results like this with such a low ERP, hence the step-by-st=
ep
perfection of the system. Thanks to all that have picked up the challenge!
