Instead of a totally vertical antenna suspend a full size one wavelength loop for both TX and RX. orientated in the desired direction.
A brilliant idea.
A full size loop for 630m, i assume you mean a vertical loop, has a diameter of 200m. I suggest to use this rotor: http://img520.imageshack.us/img520/7206/motorzv4.= jpg :-)


73, Stefan



If I had a large tower available like the one described I would not have a problem either on TX or RX

Hi Holger,

Thanks for the information/update! Nice to know that they are proceeding and they obviously know what to do :-)

The idea with the VHF link is very good but maybe they only need to detune the TX antenna to get much better results. This can be done by a RX/TX relais (22k (ish) resistor across that). Will they try that? Maybe they can reduce the needed efforts... Using Twente SDR is of course another idea for a separated RX but it may be to far during the time the band is still closed or to copy weak local stations...

Unfortunately i am not in Heidelberg this weekend :-(

73, Stefan/DK7FC

For example, they will also use a better receiver (now R&S EK70) plus a specially designed rx/tx filter, a 472 kHz receiving loop and a second (10km separated) receiving station, linked via VHF.=C2=A0

Please listen for them = on 473,500 kHz for any cq calls. They will also use 472,500 kHz temporarily but rather like to keep this one free for other users. QSX on other frequencies (e.g. between 501 and 503 kHz or even cross-band 80m) will be announced.=C2=A0
