Spaces dont show up well in email. yes, a 5 letter call has to have a space as the 6th letter of the call plus the space that separates the call from "sez". A four letter call has to have two (+ the one for separating the "sez" Bob

Just to clarify, by right padded, you mean spaces after the call sign, Correct: (K7TEJ sez)? Rick Tejera

A new feature has been enabled for the Voice Synthesizer on PSAT2
in addition to DTMF grid and DTMF messaging to voice. Now the voice
synthesizer is also listening for APRS-to-Voice messages as well.
Here is how to use it
Remain on the 145.980 uplink and 145.825 downlink for DTMF
Using an APRS radio, send an APRS message to PSAT-SAY
Begin the first 10 chars of the message with CCCCCC sez
Followed by the text to be spoken.
CCCCCC is your callsign right-padded with spaces.
The satellite should ACK the packet uplink and then speak the text.
You can tell if APRS-to-Voice is enabled if this 1 bit is on: XXXX0010.
Usually the DTMF bits are also enabled so the telemetry will usually
show as 11010010.
To do both DTMF and APRS-to-Voice at the same time, the Basic Stamp
processor has to check both the DTMF decoder and the packet decoder
and so there is a finite chance that a perfectly good uplink might be missed
So, just try again.
See http://aprs.org/psat2.html
Tomorrow I will add this feature to the users manual and post it.
Enjoy, Bob, WB4APR
