MAD Activity on September 1st and 2nd

We have set up at YMCA in EM48sq at early hour today - my 10GHz station was operational at 5:45am this morning. Reason for this early setup was a "sked" with Garth W0GR on 10GHz. Garth copies the WB9PNU/B beacon signals with significant strength almost every morning, so we wanted to try while remnants of the tropical storm ISAAC were still in the area. EM38 would be new grid for me on 10GHz.

Rain Scatter conditions

I was hoping for Rain Scatter, but all the usable storms went North out of Garth's reach. The only one remaining didn't have much reflectivity and was moving North, behind a line of trees from my point of view.

However, we have set up close to Marine Ave. at the YMCA entrance. Jim KK0JIM came to participate. Note the orange flashing light in the middle of the picture at its bottom:


Well, we didn't work Garth, although we have heard his beacon from time to time. Signal was very weak and never lasted long enough to copy even a single character in morse code. Just a few beeps and elevated noise. Not good.

Sudden burst of wind finally turned the antenna over and everything landed on the road. This has never happened before, but I have never set up with that umbrella in windy weather. Anyway, here comes a solution that I will be using from now on:


We gave up Garth at approx. 7:30 and moved to the usual location in the YMCA parking lot to try with Ron KO0Z. Signals were not as strong as usual, but we made it, both CW and SSB between 8:05 and 8:25 this morning. Signals were coming from azimuth 19deg. while direct line between us was 33deg. Signal takeoff angle was approx. 15deg. Signal was showing signs of Rain Scatter distortion. Distance 65 miles.

This was new grid for Ron KO0Z and first QSO on 10GHz ever for Jim KK0JIM who also celebrated his birthday today! Congratulations and thanks for all your help, Jim!

Packed up and returned home after that.

Tried one more time on Sunday 09/02 in the morning, right before SLAMS breakfast meeting. Rainy weather, no luck, despite setting up across the road from the YMCA entrance. We have to bribe Mr. Hepburn for better propagation next time ...

Very inconvenient rain ...

Note my car parked across the street 
AND 
the tripod anchored by the heavy battery!

Garth was unable to copy the WB9PNU/B beacon on 10GHz this morning, not even on Spectran. Too much water in the air .. and Garth reported heavy groubd fog in his area. Well, next time ...

  1. Great idea of using the battery to help anchor down the tripod. It was great working you and Jim.

  2. Oh it works .. the battery hangs about 1 inch above ground. Tripod feels very stable with that. Many microwavers use batteries or even bags with stones .. I have learned the hard way.
