On another list it was mentioned that they use the 10 MHz band for control purposes.
They apparently are using a Small Wonder Labs QRP transceiver and the onboard microcomputer decodes CW commands.

Many thanks dear Edward Chang BX1AD , BU2AI , BX2AI , BM7FVH , BV2FP for
the nice dinner tonight in Taipei where we talk about satellites operation .
I hope to make some QSO's via sat next time .
If you go to Taiwan , search for these guys , they are fine!
Some time ago I found a muTek GLNA432e at eBay. It was inadvertently
advertised as a 144 MHz unit and was also supplied with a SBLA144e schematic. So
I'm at a loss how to troubleshoot this nonworking unit. I have searched the
net but found nothing useful. If anyone knows anything about this unit, e.g.,
transistor used or even better the schematic, please let me know. It is a
vintage well built 1983 unit with RF sense switching so I really would like
to get it up and running.
For your information,

I still have not heard of anyone copying the HF beacons on 30 and 40m. (10.147 and 7.102 MHz). I am curiouis about this because our next balloon flight will only have an HF beacon and nothing else.
I have been in the 400 mile footprint most of the morning, and have heard nothing, though it is tracking out past Nova Scotia just fine on APRS... http://aprs.fi/KD2AUC-1
