Hi Joe,
The PSK transponder can not be switched off. It's always ON in AUTO Mode.
We have two modes:
Mode A - transmitter always on (by command) Mode B - transmitter turns on if a BPSK31 signal is present -> thats the default mode
See this example:
[PSK ON] W3ADO-5 beacon A 023 00 22 807 251 +6 W3ADO-5 beacon A 024 00 22 806 251 +8 W3ADO-5 beacon A 030 03 23 795 252 +13 W3ADO-5 beacon A 031 00 22 794 252 +13 ... W3ADO-5 beacon A 040 00 23 790 249 +16 W3ADO-5 beacon A 041 15 23 788 249 +17 W3ADO-5 . [reset] W3ADO-5 beacon A 000 12 23 797 247 +16 W3ADO-5 beacon A 001 00 23 790 249 +17 [PSK AUTO mode ON] W3ADO-5 beacon B 002 34 34 803 245 +12 W3ADO-5 beacon B 003 99 33 791 249 +15

Hi Paul,
Are your sure? Or Possibly it is the other way around? Where the PSK is what gets shut off?
Reason asking is My 10 meter side has been no problem, even 5 watts, is enough to activate her. My weak side has been the recv.
But Sunday I put together a 70 cm 9 ele beam and listened and on both passes not only was it full quieting it was FULL SCALE!!
Then at the 00Z pass this evening I was ready for transmit too.
I listened first and heard nothing, about mid way I started transmitting, and nothing at 5 watts, 20,, 50 and even 100 not once did she come awake.
Does this happen?

The power budget of the satellite is not able to sustain both the digipeater and the PSK31 transponder throughout all parts of the orbit. When the battery voltage drops below a certain threshold, the secondary mission of the satellite, the digipeater, is shut off. The primary mission, the PSK31 transponder, remains operational.
When the eclipse percentage of the orbit drops, one of the command stations will turn the digipeater on again.

NO-84 seems to have its ears turned off for the few days. Anyone know what's happening there?
