Hi Toni,
Thanks about the weblink. Yes, 1 W ERP can be done with a QRP TX,
supplied by a 9V block battery ;-)
BTW i just remembered your call from some HF QSOs i think. Do you have
a digital logbook? Probably it was on 30/40/80/160m but somehow your
call isn't strange to me :-) If so, your CW must be above 60 BPM and so
i want to do a fast QSO with you! This dream isn't realized so far
since most LF CW OPs are rather seldom QRQ OPs :-)

Hi Stefan
Thank you for the info.
The site we will use is Sottens, where the last
medium wave broadcast transmitter in Switzerland was shut down Dec. 31.
last year.
I will probably not have to put a Kilowatt of LF into the 125m mast to
get 1WERP, hi. Here some pics
from the site.
I'm looking forward to have a QSO with you in good old CW.

Hi Tony,
We haven't had QSO before but i am looking forward with interest to
your LF activity and hope to be QRV as well. I am using a 100m or 300m
vertical antenna and i am QRV in regularly CW. You will hear my signal!
:-)
I've used an ordinary 50 Ohm attenuator of 14 dB just to prevent
overloading my 706 as i used a 100m vertical recently. But the AF
signal levels were poor so don't forget your headphones, as i did ;-) I
will try a 50 Ohm band filter in the next test to prevent overloading
by stations at 153 kHz and 129 kHz and all outside the band...
Good luck!

Hi Mal
Thank you for the response. So I will take my attenuator box to the
site, connect the mast to the RX and see what happens. It will be
difficult to get a receiving antenna far away enough, and I hope we
will not get to much QRM from the line running up the mast for the
lights, or from something else. But I will have a lot of help there.
Ham engineers and operators. May be some of them will get the LF virus
and get in my footsteps. Soon I'll be back with more news about this
event and I'm looking forward with pleasure for our next CW QSO.
Digital modes are not on the plan - maybe QRSS3 if there is a need for.

BTW. For those who speak German: I will report about the event on my
Blog: www.funkperlen.wordpress.com
