Re: LF: EbNaut Tx and PTT function (Wish list)

[Markus Vester <markusvester@aol.com>]

Hi Paul,

no joy yet: it looks like the PTT output simply reflects the inverse keying, i.e. "DTR, RTS=PTT" behaves the same way as "DTR-RTS".

BTW There's another small oddity, also present in previous versions: On a machine which is running local time (CET), pressing e.g. "Next Min" and "Prepare"  automatically enters the correct next UTC Minute into the time field, but produces the message "Start time already gone".  When I manually advance the UTC field one hour (i.e to the next CET minute), it starts ok. This issue does not show up on another machine running in UTC timezone.

Best 73,
Markus (DF6NM)

Added.  Version 0.9 of ebnaut-tx

  http://abelian.org/ebnaut/software_ms.shtml

Completely untested because I don't have PC to hand with a Windows emulator and a COM port.

Give it a try and hope for the best.  The PTT should come
on during 'test' mode, should come on 2 seconds before the start of each transmission, and should go off immediately after the last symbol.

If the next repeat starts within 2 seconds of the end of the previous repeat, the PTT should stay on.
