    I decoded 'ONT when I was on the vertical, but not on the loop, even though he's twice as close to me. I decoded 'RF when I was on the loop, but not on the vertical. Hopefully I'll score a small-ish drive-on base in Belton and be able to go up on the hill by the water tower southwest of me and give it a go. Alternatively, I can go to the park out near the Cedar Hill transmitter sites during the work week and see what I can hear.

    Good morning gentleman. Running WSPR this morning (as I did yesterday and
    last night), but seeing no traces this morning!

    Have drizzle and fog here ATTM (6:50 AM CDT) and theorize the atmosphere is
    not giving us much in the way of 'ducting' via tropospheric refraction.

    Open to theories on this - yesterday as the rain band moved through KD6RF
    and myself also saw a loss of 'path' - no spots - until the rain passed, allowing
    the lower atmosphere, the troposphere to 're-stratify' a bit and refract some
    2m RF energy.

    73 and will be on 2m WSPR the balance of today, per plan.

    PS. Equipment setup here is a gain vertical antenna (an old KLM) and IC-910H radio.

    PPS. Just saw first trace from KD6RF at 1154z 06:54 CDT Monday

    I left my receiver running overnight and while I am at work -- I'll fire up the TX when i get home tonight. There was some ducting this AM -- I was hearing the Greenville TX repeater very well from Cedar Hill and was able to key it up.

    You may find this useful -

    Around here, the Mountainlake APRS map is pretty accurate, but it misses the activity in Gulf. There is, indeed, a tropo path from here in southern MN to Michigan most days.

    I hope you succeed in drumming up more WSPR activity around the Gulf Coast - the tropo scatter in that region seems to be pretty prevalent, and it would be interesting to see it. I've observed it while driving around the Gulf on I-10, listening to FM repeaters, so weak signal stuff should be that much better.

    Version 7 of what? I see only version 2.12 for WSPR or did I miss something?

    Thanks for your time.

    Interesting coupla days!

    I suspect if everybody was on horiz polarization (which, as I understand, has a bit of an advantage for low angle propagation), then we really should start racking up the spots.

    In California, I/we did a bit of cross-polarization testing. I was surprised to find that polarization was pretty much retained, even over hill and over dale. I had expected polarization to get all jumbled over the 100 mile paths, but it still had a good roughly 10 dB or better preference for the same polaization at TX and RX.

    And of course gain antenna, esp at the long distyance end (Richmind) could make a big difference :) 10 or 12 dB gain there, and it might keep the energy off of the near-by high-Doppler Aircraft, and might shine it on the mid-path Aircraft that would give us a high reliability ACS link. Just like the KC6KGE link in Calif.

    I will be getting a better antenna setup here as well, and get it up higher than the crummy 12 ft it's at now - as we know, elevation makes HUGE difference in low-angle gain.

    Anyway, thanks all, and hope to see everyone again next week.

    Noticing some good prop.
    Just turned on my station. 20 watts into 2 phased loops at 30'

    Sure looks like you're in there, 80 Hz below band edge....
    It won't take much to start getting decodes here - I will gain a good 5 or 6 dB just with change in antenna height. Maybe next week I get to work on ham stuff.

    Sure thing Rob. You'll have to find a copy somewhere, but V7 allowed you to exchange reports etc similar to JT65/9.

    Oh, and please folks, don't leave your WSPR transmitter unattended!
