Hi Bill, If you look on N4HY's SmugMug https://n4hy.smugmug.com/AMSAT it shows pictures of both AO-7 and AO-6 in construction. I can say from studying the pictures of both AO-6's and AO-7's battery packs from that page, that they both look identical in construction as far as i can tell from the picture. Also a quick google search turned up these frequencies: *Uplink* (MHz): 145.900-146.000 *Downlink* (MHz): 29.450- 29.550 *Beacon* (MHz): 435.100. Yes it would very cool if OSCAR 6 came back to life like its brother AO-7. Although having a repeat of AO-7 would be rare, its possible!

Very cool stuff on that SmugMug. Love the internal pictures of modules on AO-7. And yes the battery packs look very similar.
I might try and take advantage of its beacon being near another sats downlink to try and hear it on the SatNOGS network to do some checking in on it now and then. As its beacon falls near falconsat-3 70cm downlink at 435.103 Mhz. So if they happen to be over the same station at one time I can possibly catch AO-6 if it ever repeats AO-7.

Unfortunately, OSCAR 6 had a problem that required it to be constantly commanded to stay on, so even if a battery cell were to open, it wouldn’t stay on like OSCAR 7 has.
Phil Karn, KA9Q, has archived many of the early AMSAT Newsletters. The issues from 1972 on contain lots of information about OSCAR 6.

This idea sounds very interesting. Are you going to search for overlapping passes by hand and listen by ear or do you have a plan for automating the search?

Hello,
If it is of some use AO-6 tracking at: http://amsat.org.ar/pass?satx=ao-6

Thanks everyone who has replied with information so far!
Based off what Paul has said there might be no point in trying anything.
Douglas I am using a program I wrote for checking when two satellites are close to each other to search for times when they overlap.
I plan on listening to it using SatNOGS. (That is once I have my ground station working again.) Which will allow me to listen to it easily if they pass near each other by making a new observation.

Given the historical issue with AO-6 not staying on, simply listening will probably not suffice. I expect it needs to be commanded on, and be sane enough to comply, in order for us to hear anything.
But, yes, could be an interesting thing to try. AO-7's command processor was still somewhat functional, if I recall. Now we just need to figure out how to send the commands...

So even the beacon could be off (if it had power to where it could be on). Interesting as based off what I have read thats the one transmitter that could never be commanded off which means it would not make sense to be able to command it on. Unless you mean that the on board systems not transmitting because they themselves were not staying on.
