Hello Jay,

OK, i am limited in power and time so we just have to try what is=20
possible. If Tony/EI8JK will receive anything, it would be a new record=20
in distance, even into your direction. Maybe we will get some=20
informations if the ODX is stepwise increasing... Not sure if the=20
Dreamers Band can be compared to the Alpha reception since the Alphas=20
are several transmitters (for one frequency, e.g. 11904 Hz) on several=20
locations, as far as i know.

Be optimistic, that's maybe the best we have learned this year so far ;-)

> What modes / times / frequency / power  will you be transmitting?

As usual i will plan DFCW-600. It is best viewed in 4.5 mHz FFT (about)=20
and 1 minute per pixel. After that i want to transmit a stable carrier,=20
maybe 30 minutes or 40. The best is, if you make a recording within=20
SpecLab! That would be very(!)interesting for me and others since your=20
RX situation seems to be very impressive!
The frequency will be 8970 Hz, as usual. I am awaiting my second GPS=20
module. Ebay says it is already shipped (Hongkong) on 9th Oct but still=20
not here. If it will be here until saturday i can transmit GPS synchron!=
=20
But the DDS VFO isn't bad i thing, as long as i can prevent strong=20
temperature drifts.
I want (as usual) apply the full power that the generator can give,=20
means about 600 W, maybe 650 W. This may result in 50 mW ERP!

If there is enough time without rain and wind, i will transmit on 6470=20
Hz as well, same mode and power.

If the wind is strong and stable i will perhaps roll out the 100m kite ant=
enna and will switch them in series, i.e. trying a 300m vertical.
