This very well could have been it as well, never checked the antenna, it had snowed here, yesterday was nearly up to 32 degrees, might have melted some ice off the antenna. Whatever it was, it's back to normal this morning.

We tried a TRAM dual band antenna, looks just like the diamond type of setup, on UHF repeater. It worked well, we did some benchmark testing, etc. First serious ice storm we had on the hill the radome took on about 2" of ice, as did the radials. The receive sensitivity went WAY down in the dirt, noisey and not usable from just a few miles away. A trip to the hill checked out everything inside, 80 watts out to the antenna with no SWR, nothing seemed to change at all in the transmit coverage. The receiver was fine, duplexer was fine, etc. I climbed the icy tower, knocked all the ice off the radome and radials and the receive sensitivity came back. We can notice the decrease in sensitivity with as little as 1" of ice hanging on the radome...but transmit does just fine no matter what. Whatever it does, apparently it does not affect transmit and receive the same. Good Luck! Daron N7HQR Yahoo! Groups Links Yahoo!
