Good news Bob !

It is possible to add PSAT2 (or NO-104) to page ?

An other good idea would be to put satellites names in alphabetical order to facilitate find them on the list

Asunto: [AMSAT-BB] PSAT2 VHF Awakes


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.



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.

There is a user operating manual available on the PSAT2 web page:

Another time change occurs for us tonight; we'll be at GMT-9 for a couple days, and that gets in the way of making the AO-91 pass at 28/1952Z. In the very off chance that I can make that one, we should be in CK08 at the time. Later on, I'll try to make passes on CAS-4A/B, AO-7/CW, XW-2F, and RS-44/CW in the 29/0130-0333Z time frame; we should be in BK98 then. A little later, we'll cross into BK88 hopefully in time for the 29/0506Z pass. 73/Jim, ND9M
