Re: [amsat-bb] PSK-1 and P3DT Program not working

[Robert Rice <rcrice@xxxxxxxxxxxxxx>]

Check the following:

1.  Set the PSK-1's RS232 speed to 1200 baud.  With telemtry coming in at 400
baud, 1200 is more than fast enough.  There have been reports that PSK-1s set to
9600 have been unreliable.  I wonder whether this is related to the firmware
version.  Which firmware version do you have?

2.  Are you sure that the PSK-1 is set for 400 baud telemetry?  I made THAT
mistake myself.  No hardware mods are necessary, just set the PSK-1 to 400 baud
telemetry mode.

3.  Can you see the PSK-1's menu like below?

4. Do you have a signal that is at least an "S" unit or two?  Below about S2, I
get very erratic results?

5.  Make sure that you are looking at something other than a "D" blaock, it is
all gibberish since it is a memory dump.  You have to wait for other kinds of
blocks to see anything interesting.  Leave it on for a while and see what you
get.  After 10 or 15 minutes you should see something in P3T.

6.  I am putting together a FAQ for these issues.  If you get your problem sorted
out, drop me a line.  I'll add your solution to the list.  I've just started
this, so there is not much there yet.   http://ao40.homestead.com
