PSAT2 VHF awoke from an 8 Mo slumber on 26 Apr 2021. We have no idea why. Its telemetry looks fine. Volts between 6.2 and 7.0 volts (5 NiCds). Exterior temps between -18 and +22 C. See http://aprs.org/psat2.html
PSAT2 will NOT be in APRS mode but a brand new experimental mode for DTMF uplink and VOICE downlink. So you preload your grid and callsign into a 16 digit DTMF memory in your radio and when the satellite hears this it will assign a QSO number and QSL the grid by voice and then also generate an APRS packet for collection by APRS operators. There is even a way to send back a DTMF QSL so you can make it a 2-way DTMF. contact.
Successful DTMF grids and messages will appear on a special URL on the PSAT2 page (above). To QSL, you key in that stations 2 digit QSL number and then dump your pre-loaded QSL DTMF message..
Since this is the first time this transponder is on the air and because a DTMF uplink takes maybe 4 seconds, we dont want the uplink saturated by a bunch of newbeees initially until we see if it actually works. So read the docs and be sure you know what you are doing.

Good news Bob !
It is possible to add PSAT2 (or NO-104) to https://www.amsat.org/status/index.php page ?
An other good idea would be to put satellites names in alphabetical order to facilitate find them on the list

NO-104 is there in the drop-down list under "Submit Report". Satellites drop off the chart when there are no observations reported for a week.

Thank Bob,
So using the DTMF callsign encoder I send *1320 632780 2277 # *(Grid FN20) (Call N3CRT) (decimal key code)#
I get a QSO number via the digitalker reply. I hear someone else get a digitalker reply QSO number and I want to QSL to that station. So I send B(2 digit QSO number of the other station) then 40 (QSL) 632780 (my call) 1320 (my grid) or are the last 4 supposed to be my decimal key code? 2277? I'm only hung up on this last part before giving it a go. "Then the remaining *CCCCCCxxxx* finish off the transmission with the full encoded callsign as in the grid format.."
is the xxxx my decimal key code, or my grid? I am guessing that the CCCCCC call sign wont make sense to the decoder without the decimal key code.

yes, * No spaces in the DTMF string. And yes, your keycode is required. Im not sure what the "B(2" typo is in your email?

So you preload your grid and callsign into a 16 digit DTMF memory in your radio and when the satellite hears this it will assign a QSO number and QSL the grid by voice and then also generate an APRS packet for collection by APRS operators. There is even a way to send back a DTMF QSL so you can make it a 2-way DTMF. contact.
Successful DTMF grids and messages will appear on a special URL on the PSAT2 page (above). To QSL, you key in that stations 2 digit QSL number and then dump your pre-loaded QSL DTMF message..
Since this is the first time this transponder is on the air and because a DTMF uplink takes maybe 4 seconds, we dont want the uplink saturated by a bunch of newbeees initially until we see if it actually works. So read the docs and be sure you know what you are doing.
There is a user operating manual available on the PSAT2 web page: http://aprs.org/psat2.html

Thanks for clarifying that.
My B(2... was my attempt to reference the 2 digit QSO number of the other station. So my QSO QSL reply to another stations QSO number 13 would look like this:
B13406327802277#
Is there a problem with timing or timeout of the satellite receiving the string of DTMF if I were to try to hand enter the B13 and send, then kick over to my DTMF memory to send the stored QSL reply for the rest of the string 406327802277# ?

yes,
- No spaces in the DTMF string.
And yes, your keycode is required. Im not sure what the "B(2" typo is in your email?

So using the DTMF callsign encoder I send *1320 632780 2277 # *(Grid FN20) (Call N3CRT) (decimal key code)#
I get a QSO number via the digitalker reply. I hear someone else get a digitalker reply QSO number and I want to QSL
to that station.
So I send B(2 digit QSO number of the other station) then 40 (QSL)
632780 (my call) 1320 (my grid) or are the last 4 supposed to be my decimal key code? 2277?
I'm only hung up on this last part before giving it a go. "Then the
remaining CCCCCCxxxx finish off the transmission with the full encoded callsign as in the grid format.."
is the xxxx my decimal key code, or my grid? I am guessing that the
CCCCCC call sign wont make sense to the decoder without the decimal key code.

PSAT2 VHF awoke from an 8 Mo slumber on 26 Apr 2021. We have no idea
why. Its telemetry looks fine. Volts between 6.2 and 7.0 volts (5 NiCds). Exterior temps between -18 and +22 C.
See http://aprs.org/psat2.html
PSAT2 will NOT be in APRS mode but a brand new experimental mode for DTMF uplink and VOICE downlink. So you preload your grid and callsign into a 16 digit DTMF memory in your radio and when the satellite hears this it will assign a QSO number and QSL the grid by voice and then
also generate an APRS packet for collection by APRS operators. There is even a way to send back a DTMF QSL so you can make it a 2-way DTMF. contact.
