Re: AO-51 L/U Mode



For clarification, is the fading on the uplink or downlink signal? There would be no explanation (that I can see) for any difference in the downlink, but remember the uplink is on a different antenna for L than for V. The same antenna seems to have some spin fade on S, in my personal observations/opinion. So...it wouldn't surprise me if it exhibited some periodic fades on L too...

PS My L module was installed last month, and I finally picked up a L antenna....maybe I'll be QRV soon.

GM All and Happy Holidays,

Geen enjoying the L/U mode on AO-51 and just a short report.

Worked W2XB (Don), WI2W (Steve), N8BBQ (Ed), K5HGH (Bob Nice IC-910H and
Directive Antennas for 1.2 GHZ) and WA4IVM missed his name.

Bob noted that the signal was fading in and out even under high power in the
L/U mode.  I noticed the same here in Montana on stations I worked (Strong
then faded then Strong).  Sat is not is normal consistant strong down link
as in V/U.

This is just a note for Mike (KE4AZN AO-51 controller - Tks for L/U Mode
Mike).

Anyway its still a challange and fun.  I have been able to work with just a
12 turn helix and 1 watt at 1300 Km and 5 watts at 2800 km so the receiver
is doing its job.

Picture of my 1.2 GHZ antenna by Directive at:

Cheers all will be on next pass...
