HI Guys

I wish this was problem here!!!

Here's hoping they give us the band in Canada in the new year.

Dear Warren, LF,
well your point about the winter night is perfectly understood... A fixed QRG will not be a problem for transatlantic contacts, as long as we Eu's would transmit in the lower band. Only if during the second half of your night you'd aim West, and someone from over there might want to fire up near your QRG, the two of you could end up blocking possible coast-to-coast contacts. There is also a technical answer: you could perhaps tune remotely using a relay, or even connect the additional capacitance at the input of the feedline. It may add in a bit of extra loss but not much, as only 2% of the reactance would need to be switched. Best wishes,
Markus (DF6NM)

Markus,

My antenna tuning unit is outside 100 meters away from the ham shack. I am unwilling to go out in the winter night to retune the antenna to QSY to the lower frequency segment.

Dear LF,

the passage should have said:

Taking into account the path of mutual darkness, this would mean that all stations should transmit in the UPPER band during their evenings until local midnight, and then QSY to the lower band for the rest of the night.

Sorry for the confusion.

73, Markus
