Hi Jay,

We still have no success in Jnue so if we want to get a full call=20
detection in each month we have to find a suitable days soon.

Well, all right about the DST stuff. However you know i simply like=20
transmitting so i usually do not care about the condx. From time to time=20
there is a surprise een in "bad" conds. Like yesterday! 4X1RF temporary=20
started his grabber in Haifa and to my surprise we got very good results=20
over that 2850km distance. About 25 dB S/N, see=20

Sure, crossing the pond is another story. Let's do it in the coming days =
:-)

BTW what about your TX? Are you ready for a transmission?
