Hello Toni, group,
=A0
I measured the=A0HE3OM=A0signal=A041= dB down on=A0DCF39.
Distances to HE3OM (504km) and=A0DCF= 39=A0(515km) are almost identical.
This might give the US stations a cl= ue what signal strength they can expect from HE3OM and what QRSS speed Ton= y could use to be copied.

Dear Jim, Mal and LF Group

Unfortunately the tower is not nearby my house and I can't leave the= station running unattended. And the nights I can spend in Sottens are lim= ited by my health and my wife, hi. So there is no trial before, I have jus= t next Friday night.
If I take a look at the reports we got in the past two weeks from stations= 2000-3000km away (always good audible), it should be possible to span 600= 0km using QRSS10.
On the receiving side, we may be able to see stations let's say with= QRSS60. This would mean, that we could make only one or two QSO's. Ma= y be it's better to try Crossband: we transmit in QRSS10 and listen on= 80m. This would give more stations the opportunity to contact us. However, if there is a station from the East Coast we copy= in QRSS10 it would get the priority.
What do you think about this approach?

Dear Toni, LF Group,

HE3OM has the advantage of a much stronger TX signal than most Eu stations= , so I guess you have a good chance of being copied in NA on Friday night,= unless the propagation is very poor. But as you will have seen from the= activity last weekend, forward planning is always a good thing, especially where a single QSO takes hours. If pos= sible, I would suggest transmitting some beacon signals from HE3OM between= now and Friday, so that North American stations can get a good idea what= QRSS speed can be copied from your station. Also, try to receive any W/VE beacons that might be running, so= that you also know what the requirement will be in the other direction.= Finally, I have usually found reception of US stations is best just befor= e dawn here, so make sure you are not going to be busy on Saturday!

Good luck,

Cheers, Jim Moritz
