PSAT2 appears to be operating normally after awakening on 26 April from a 9 month sleep. All VHF and UHF functions are intact. The APRS digi is off to encourage experimentation with other modes. Such as DTMF Grids, PSK31, SSTV relay, HF voice SSB uplink, UHF FM down.
The latest Bulletin from PSAT2 on May 1 shows these callsigns have used the DTMF Gridsquare report or sent a DTMF message. The goal of this mode is to allow anyone with ANY radio to do a digital communication without having to have a specialized APRS data mode. ALl you need is a DTMF memory to store your callsign digits.

Malking a DTMF grid report is trivial from any dual band radio and requires no mode changes. ONce you have loaded your grid and callsign into a DTMF memory, all you have to do is change the VHF uplink to 145.980 and downoink on 145.825 and when the bird is in view, TX the DTMF memory and listen for the VOICE response.
You should also hear the APRS packet response and display it if the downlink is set for APRS. PSAT2 report that Grids have been captured from these stations:

Tried it tonight with the D72A and sent DTMF on VFO B. A couple of times I heard “APRS TT” or “APRS Repeat” after transmitting. Might have been a coincidence. I looked at the page and didn’t see my call listed so assume it was for someone else

I think the APRStt voice response is the 1 minute id. The APRS repeat I dont remember wha itr means...Maybe I can look it up. bob

I think you're right. Voice sounded like APRS TT and it repeated a few times - I didn’t check it once a min or not

It was pointed out that I omitted the most important part., that a monoband VHF radio is all that is needed to make a digital/voice GRID contact via PSAT2. Not a dual band as iis required for APRS.
So Here is the revised announcement.

The voice response is for other VHF DTMF users also without APRS.
You should also hear the APRS packet response that should be picked up by APRS IGates to place the DTMF report (converted to packet) to make it to the DTMF capture pages on http://aprs.org/psat2.html

Is the voice downlink on 145.980 or is it on the APRS frequency 145.825?
No luck getting in yet on DTMF from Maryland with such low passes.

Stephen I made this video some time ago ;
I hope it helps. 73

Thanks, that answers my question. So the voice is on the APRS downlink along with the data.
-Stephen
Yes, You can simply monitor 145.825 and if you ever hear the low-audio voice announcement once a ,minute "aprstt" (followed by a packet) then you know PSAT2 is in VHF DTMF mode and you can make DTMF contacts using your two DTMF memories One for sending your grid and the other for sending a QSL message to complete a contact.
If you hear someone elses grid "WB4APR grid FM19 contact number XX" then you can respond with a manually keyed "BXX" followed by the QSL DTMF mdmoery to complete the contact. Details on http://aprs.org/psat2.html
