KD - The WSJT-X FreqCal process should reliably get you very close unless your rig is drifting badly. You might try FreqCal at cold start, after 1 hour on receive, and after some high-duty-cycle trans

I spent early Saturday afternoon in DM55 in the Cibola National Forest south of Thoreau, NM. In the couple of hours I had there, I enjoyed the 6m opening that stretched as far east as EM64 from my loc

Actually, I'm saying the multipath you describe (time-invariant coherent interference) should not produce what you saw. If I understand the physics correctly... If you consider a signal transmitted at

If I correctly understand, you saw multiple traces offset in frequency, not time? I think many people have now seen this on 6 m (I'm among them), and it's not hard to believe the effect could be worse

I am very curious - what characteristics of these signals led you to conclude multipath was the problem? What was painfully obvious about it? Should multipath be non-reciprocal? Getting an audio recor

I'll be roving again for the contest. 6 m: 100 W + Moxon 2 m: 5-80 W (depending on amplifier behavior) + 6 el. 432: 5 W + 11 el. Any mode you would like. Saturday 1800-2000Z DM55vf 2300-0100Z DM56ug S

I stayed pretty close to home for this one: DM75 and DM74 Saturday, and DM55 Sunday. Saturday was not great, although it picked up somewhat later in the day when I was in DM74. I was happy to work a f

Perhaps the dupe fear is related to the apocalyptic warning that at least my logging software issues when I'm about to enter one? Please tell me and perhaps a few other inexperienced contesters why we

Great writeup, and I understand the concerns about FT8, but I'll reinforce what Mike says a bit with an exchange I had with another rover when I was in lonely DM83. The attempt ultimately failed becau

Yes, Saturday was grim, especially in DM83. Wickedly hot and windy. I heard a total of 3 NM stations: K5AM (sometimes strong); WB2FKO (a couple weak decodes); and AI5I, God bless him, who somehow mana

I'll be starting the contest near Roswell Saturday, and slowly working back home. 100 W + Moxon on 6 m 80 W + 6 el. yagi on 2 m 5 W + 11 el. yagi on 70 cm FT8, CW, SSB on all Approximate schedule: 6/8

I have wondered the same thing. On my antenna stack, which is not even that closely spaced, I have played it safe and disconnected the coax on the non-transmitting antennas. So far. I had a bad experi

I'll have the usual Moxon at 20+ feet, and 100 W. I've made a few random MSK144 contacts with this setup between 750 and 1600 km, without much effort. It appears we'll be at 650-700 km, which I assume

I'm leaning toward a trip to DM73/83 for the June contest. Some patience may be required, but I'd be happy to try on MS. John AA5PR

Pretty similar observations from a couple of sites in DM85/86 with very low noise, but I'd add what seemed like a decent 6 m opening to southern California Saturday evening. I came to think of 6 m as

My plan for this weekend: Saturday (NM time): DM85GX Sunday: DM86JP I have 6 m (100 W, Moxon), 2 m (80 W, 6-element yagi), 70 cm (5 W, 11-element yagi). SSB, CW, FT8, MSK144, FM. I'd be happy to try j

I'm planning on a limited rover expedition this weekend, probably to DM85 and DM86. Anyone care to suggest if there are other NM grids less likely to be active (on 6 m, 2 m, 70 cm)? My antenna setup w

Someone has already done spectral testing of similar units (link below). It's a long read, but the bottom line is that at least some of these are very likely to be (cheap!) synthesizers, with spurs an

I have been interested in similar low-cost TXCOs, but concerned about what's in the package. It would be very interesting to see an output spectrum. Given that you are probably driving a mixer that is

From what I could see, almost everyone on FT-8 was running 1.8/1.9. Because I couldn't decode them with 2.0, which I switched to a couple of weeks ago...to keep up with the meteor scatter folks, who s
