Tomorrow's forcast:

40m SSB:


20m SSB:



40m PSK31:

20m PSK31:


So... ya wanna do PSK31?  Or stick to SSB?

If we go with PSK31, I suggest that we move off the main PSK frequencies by, say, 5kHz.  Do we even have enough PSK31-capable people out there to bother trying?

How do you translate the maps?
If me in Michigan is blue or 0 to 10% that means what?
If me in Michigan is red or 90 to 100% that means what?

In the last 24 hours I got on 20 meters at home.  I've got just about the cheapest/simplest wire antenna setup imaginable running inside my attic.  Apparently it was good enough to make a "5" signal report from a QSO in Long Beach, CA.   In the next few days I'll be stringing up wire length to cover 40m as well.  I also have a decent 4:1 balun on order that'll help a bit.

The 40m wire will take a bit more planning, as I don't have 70 linear feet, so will make some "W" or "Z" shaped pattern.
Here's a crude visual of what I'm doing:



If conditions are appropriate, I hope to join you all next time.

Add a crystal to the middle and it could be a hood ornament for a German auto....

Won't be able to make this Sunday's session, as I have been given other plans.  See y'all next week!

I think I'll have better success if I take all of my equipment outside, I think I'm getting interference from "stuff" in the house.

Should have a warm Sunday coming here soon.

I will share my flu with all the 'twice a year' family at my church.

Sounds good, I think I can make it this week.

Chad, did you get your RFI problems sorted out?  I just flipped on 14.070 USB, the 20m band PSK31 frequency, and it is very busy.  Can you hear those signals?

Carl, you up for a session?

I will give it a shot and jump into chat about that time...I go to BOL for a maintenance visit today and the antenna should be dry enough.

I'm going to take my SW radio out side and turn off my inverter and any transformers not in use.
If I have any RFI problem this should fix it.
