Re: LF: WSPR-15 this weekend

[N1BUG <paul@n1bug.com>]

Hi Stefan,

Yes now I remember something was said about the DCF sidebands last
winter but I could not remember it exactly. I will go to .620 for
tonight. Thank you!

What I plan tonight is one WSPR-15 TX period beginning at the start
of the hour, 00 minutes. Then WSPR-2 TX at 18, 22, and 26 minute
periods. The other half hour will be receive only, giving me a
chance to listen on both the even and odd WSPR-15 slots.

I can very easily change this to repeat the same TX pattern in the
other half hour but this leaves no WSPR-15 RX periods here. Let's
see how tonight goes. I welcome any suggestions about what will be
most helpful to promote the WSPR-15 mode... split the time between
TX and RX, or TX more? I would like to keep some WSPR-2 TX periods.

This little PA will handle 100% duty cycle but I am concerned about
that antenna system resistance decrease I see during every TX cycle.
It's really quite a big change during the WSPR-15 transmissions. I
must investigate this.

73,
Paul
