Hi Guys

  "Live tropo" and Hepburn forecast maps show nothing, but 10Ghz and 902 signals between Gary (W0GHZ) and I were
up by at least 2 S units this morning. Nothing on the radars between us either.

  902 was good enough for FM... carrier only. Gary was full quieting on this end, modulation peaks would cause the sig to 
"noise up" almost like excessive deviation. Gary and I have not often been able to work on 902 FM. Signals exceeded 40db 
above the noise on the SoftRock IF receiver on peaks.

  On 1296 Gary was 30db above the noise on peaks. BUT he runs considerably more power on 1296 than 902. I do have a preamp on 902, but not on 1296 ... maybe I should. DEM 1296 xverter. 

  10Ghz ... very nice 22db above noise signal peaks. HOWEVER the signal sounded much better due to what I have called
"good tropo multipath". The signal was wider than normal and as a result had a very "rich" sound to it. Most mornings with
this weather we have 12-15db peaks at best and a very narrow signal.

  There was no multipath on 902 or 1296, the CW signals were very narrow in bandwidth.

  Note ... Local temp was 50deg, Humidity 62% and we had/have a screaming N wind at 17mph with stronger gusts. NOT
what one would expect to be a good tropo morning.

  I am NOT hearing EN43 or EN53 2m beacons, so 2m seems to be flat.

  A fun and interesting morning ...... I also worked K0RI in CO on 2m MS and Arliss in DN75 on 6m MS both on SSB and 
WSJT.

73 all ... Bill  K0AWU  EN37ed
