[UK-CONTEST] QRP

[Ken Eastty]

My MFJ-249 produces about +25dBm - 300mW. It's not too surprising that this can be heard some distance away.
I remember hearing a tale that one of the amateurs on the staff of Brentwood (Essex) GPO HF receiving station
(now QRT) worked the USA one night shift using a BC221, also not too surprising as the antenna
used would either have been a Rhombic or Franklin array.
'Dummy' loads have also been known to radiate too, I believe the 20kW TX at Ongar radio HF on the London  - New York HF circuit once ran all night on the (un-screened carbon filament) dummy load, the story at the time was that no one noticed!
I also remember Ernie G3ERN(long SK) working the USA with a single(OC71?)transistor TX on 160M.

  ? I wonder if anybody has a DX record for a QRP QSO using an MFJ antenna analyser?
I was tuning my top band dipole with the MFJ and was told that my radiated signal from it
was S-9 plus 20 db about 3 miles away at a friend's house. Carrying this further, I then managed
to "QSO" another friend about 8 miles way at about S-6, followed closely by yet another with a
signal report of about S-6 around 18 miles away.

? So, be careful when using your MFJ, you never know who is listening!

Oh yes, a superb method of keying was simple hand capacitance on the tuning, producing a

somewhat chirpy note, but readable!?


?Can anybody beat this record?? It reminded me of my leg-pull in the late fifties, when I managed
to give Pat G3IOR a ZL0 on 20m CW by keying my Heathkit GDO, loosely coupled into my end
fed zepp.
