I will leave mine on overnight, although it would
be a miracle if you made it this far on my mediocre set up.
I might also lay some wire out and make an "earth
antenna" too.
I'm reasonably new to the group, just
re-registered, although I did lurk in the background last winter.
The intention is to get myself a better setup for
the winter months and build myself a transmitter for 136 and maybe have some fun
along the way.
Station location is fairly close to Mizen Head, the
opposite end of Ireland to Finbarr (extreme SW), in IO51DN.
In the meantime I will continue to
"lurk"

Folks,
Well I need to do an estimate of ERP with the
"earth antenna", so will try to measure this in the coming days. Jusging by
reports so far the system is about 6-10dB down on my top loaded vertical
antenna. The power from the transverter is 5W still but with the vertical the
ERP was only around 1mW (calculated and measured). So, at a first guess, the
ERP is probably around 200uW but perhaps with directivity because of the loop
action.
Rik, I could run it overnight tonight if you like to see who
can copy me. Anyone else willing and able to listen overnight tonight
please?

3 watts into my 600 meter 70' vertical gets me easy CW

watts CW in daylight with that Earth Electrode antenna, then you know it
works damn good.
