Given the current problems with AO-51, should we be listening for a signal on 435.150 Mhz? Could another downlink, such as 435.300 MHz, get switched on randomly?

There have been a few comments about having the control operators do this or that. Are you guys not listening or what. The thing has been on its last legs all summer after the last episode with the batteries and they had enough trouble trying to keep it going then.
Seriously people, get a grip. You really think they are going to try and activate other things when they can barely keep it going as is. Did you not see the post about us being lucky its even turning back on after eclipse, enjoy it while it lasts???
Some peoples kids I swear.

It's unlikely. We think the 435.150 tx is still on a very, very low power, so if you have a good station you might hear it if the battery voltage comes up enough.
This week I want to look into trying the S band transmitter. Being from a cordless phone, it may still work at the lower voltage available.
We've not given up, but patience is the order of the day.

Drew: Thanks for the info. I'll use the big antennas and switch on the preamp.
Kevin: I wasn't asking the ops team to make any changes. I was wondering if AO-51 might randomly start transmitting on a different frequency. Just searching for "signs of life." :)
