Mike, KM0T (EN13vc) and I worked on 24 GHz snow scatter at around noon
today. My grid was EN34fs, Scott County Towers, a distance of 175.5 miles, or
274.2 km. Mike and I have been trying the EN34/EN13 path for several months
and had yet to hear each other until today. After months of listening to
hiss, it sure was nice to hear Mikes CW signal !
There was snow between us, but no snow on my end. Temperature was 20
degrees F with no wind. We found each other on 10gigs with good S9 signals which
helped to line up dishes on 24 GHz. The bearing on 10 GHz was somewhat
broad, sometimes typical of rain scattter. I started to beacon on 24 GHz and
Mike found me pretty quickly .... signals on 24 GHz were not strong, above the
noise, and with no tone; definitely scatter, much like aurora signals ....
what I like to call a very nice CW contact. We did tried SSB and we could
tell that there was a signal there, but it could not be read. FM resulted in no
detection at all.
Following this I drove to EN25xb, the site by Howard Lake, but by the time I
got there the snow had moved on. Although EN25xb is actually a few miles
closer, condx on 10 GHz to Mike's were not very good with only S3 like signals
and with nothing at all heard on 24 GHz. We also tried a skewed path to a
heavier area of snow fall, but signals on 10 GHz were very weak.
We have tried EN34 to EN13 on 24 GHz via rain scatter before with no luck to
date, but perhaps snow scatter has some advantages at 24 GHz. Both Mike
and I are running about 4 watts and 19" dishes
