AA5PR/R contest roving plans
I'm heading northeast for the upcoming contest next weekend. As usual, 6/2/432, 100/100/50 W, gain antennas.
Cell service at all sites looks marginal, so I plan to send updates via Slack NMVHF when

Re: ARRL September VHF contest
I'm thinking I might try DM76/85/86 (near the convergence) next month, if I can figure out stuff like where I would sleep and what I would eat. If I do that, I too would love to work

Re: ARRL September VHF contest
At one time there was a rather large, ominous, and fairly lengthy and specific No Trespassing sign at the gate, which, oddly enough, was left open every time when I was there. If I recall correctly,

Using k7fry.com/grid/
DM74CX59LK : I have operated from this spot 2-3 times. If you need more space to put up antennas you might be able to go slightly further east beyond the gate on

Re: ARRL September VHF contest
The website has some great rover location suggestions.

The DM76 location sounds excellent.

Re: ARRL September VHF contest
Does anyone know a good portable set up location for either of those two grids. We could possibly deploy 2 meter and 432 beams and a 6 meter dipole from one of these grids.

ARRL September VHF contest
We're about 3 1/2 weeks out from the September contest. I'm hoping I can talk someone into visiting both DM74 & DM76 with 6M and WSJT capability (just in case..). Of course, we can work on 2, 222 &

If our sun had spots this size, The MUF for F2 propagation would probably extend to 500MHz or so! - Duffey

Re: FT8 performance (or, lack of) on 432
John, sometimes one signal, sometimes 2. I'm familiar with what aircraft look like on 432 beacons and this is sure what I remember. Good idea about FT4. The guys I couldn't work were NOT weak - FT4

Re: FT8 performance (or, lack of) on 432
Do you see just one (shifting) FT8 signal on 432, or more than one? I'm wondering if you also see a stationary signal. If it's aircraft, I'd also expect that it would eventually disappear, or

Re: FT8 performance (or, lack of) on 432
Well, there is a major E-W flight path between you and Phoenix.I guess you probably have planes on that path one way or another every 10 minutes or so. If you look at the slope of the frequency shift

FT8 performance (or, lack of) on 432
So far, the 222+ contest has convinced me (or, I have rediscovered) that FT8 on 432 is unusable on paths with lots of Doppler shifted multi-path, such as my paths to DEN and PHX. These paths are

Re: CQ WW VHF Result
Like just about everybody, I experienced rapid fading throughout the contest that made most of the FT8 QSOs a real struggle. Or not complete at all. Many others have suggested that getting ops off

Half the battle was just keeping equipment and operator cool enough to get through the weekend. The only major failure was the battery booster, which popped under the stress Saturday

All-in-all it was a wretched weekend for rovering in S.E. Colorado.
But, there were several bright spots -- among them was working two

John, AA5PR/R -- twice on 2M CW from each
