In both cases, we will experience truncation of the tail end of audio xmsn because PTT break causes Hermes to end xmsn before the audio completes. A feature is needed that will add a delay between PTT break seen by Hermes and the ending of xmsn by Hermes.<br>

The "Enable PTT Delay" check box actually functions exactly as
described in the hint/tooltip of the check box: "Check this box to
delay PTT OUT line after releasing PTT in".<br>
<br>
Unfortunately for your application, it is referring to the "PTT
OUT line", which is normally attached to an external device such as
an amplifier. "PTT OUT Line" is available via the RCA jack on the
ANAN-100/ANAN-100D rear panel and on Accessory Port DB25-1. <br>
<br>
I set my test delay to 1200ms and can confirm PTT OUT remains
activated for about that time period after I release PTT IN.
Unfortunately, as soon as I release PTT IN, mic audio/modulation is
no longer applied to the SSB signal, as you observed.<br>

<div>I've done some testing looking at transmitted audio
waveforms recorded off a second receiver and finding that
the "Enable PTT Delay" control under General-Options of PSDR
is NOT functioning. I've dialed in multiple hundred msec
delay and there is no change in the amount of audio being
truncated at the end of a xmsn.<br>
<br>
</div>
Has anybody gotten this to work with Hermes or otherwise
tested it?<br>

<div>Okay, I just found the "Enable PTT Delay" control
in PowerSDR (duh). <br>

sorry for the bandwidth but perhaps other dummies can
learn something<br>

<div>After participating in the CQ WW SSB
contest this weekend with a Hermes based SDR
that has only recently come into the shack, I
now realize the end of every xmsn of mine was
clipped off. When I released PTT, the audio
stream hadn't yet completed due to latency
(duh). I received a comment to this effect
during the contest and when I review a few of
the soundclips I recorded, it's painfully
evident. <br>
<br>
</div>
<div>Assuming the latency is inherent in the
Hermes architecture, I would think there needs
to be an option in the Hermes firmware to
delay the break (tail end or release) of PTT.
The option could be enabled by PowerSDR, as
well as setting the amount of delay either
manually or automatically by internal latency
calculation.<br>
