I think the PTT delay culprit has been found! I had previously checked my
WL Ports setting to make sure the radio PTT was set to Off so there wouldn't
be a conflict between software and hardware PTT. After reading through
Don's comments I reread Joe W4TV's comments below in reply to my first query
about the PTT delay. As I was in the middle of two different contests, the
SPDX and the BARTG 75, I didn't give the Joe's note the thorough reading and
thought it deserved. However, upon further review...
Joe refers to XMMT.ocx as "... asserting PTT on Winkey (all mode PTT)" and
ended that I could check it "...by temporarily setting the WriteLog port to
'None' in Router's Ports tab." At first I thought Joe was talking about the
FSK port assignment for WL in the router Ports tab, but then it struck me he
may have meant the Winkey port assignment setting. So I set my Winkey port,
which is normally COM4, to none and changed the TU type back to XMMT.ocx and
reset up the MMTTY settings. Ta Da - no PTT delay with the Winkey (all mode
PTT) port disabled! Just to check I reset the Winkey port back to COM4 and
when sending with XMMT.ocx the delay is back.
So apparently the secret for those of us who use the microHAM router and
Winkey is to disable the Winkey port setting when running the XMMT.ocx
interface. I will create a new router preset, WriteLog XMMT, which will
feature the Winkey port set to none. Should I want to revert back to using
the MMTTY plug-in I can just select my normal WriteLog preset and the Winkey
port will again be defined for COM4.
Thanks to both Don and Joe steering me in the right direction - AGAIN!

While testing WriteLog on my laptop after installing hardware PTT via the
ACC connector on the back of my TS870, I noticed a delay in PTT. I found
that I had forgotten to disable PTT via radio control after enabling
hardware PTT.
It's been well documented that using both hardware and software PTT will
cause problems with PTT and delay is one of those problems. I don't know if
this could be the source of your delay, but it should be checked. Once I
disabled PTT via radio control, all worked normally. If you are connected
for hardware PTT, go to the Setup menu in the WriteLog window, and select
Ports. Make sure Comm PTT is set to NO on the port connected for your radio.
In the BARTG Sprint 75, I used 2Tone as the main window for both radios and
used hardware generated FSK. Despite the blue characters going out ahead of
what was actually sent, this setup worked very well. I didn't use my laptop
because it doesn't have any legacy COM ports, only a USB to serial adapter.
I have 5 legacy COM ports on this PC. Two were used for radio control and
two were connected to transistor interfaces for FSK and PTT. There was
absolutely no delay in PTT.

I see no difference in PTT lead/tail times with either the SM6SRW
MMTTY plugin for Writelog or WriteLog's XMMT.ocx support.
What are your WinKey Lead/Lag times in Router? WriteLog's XMMT.ocx
support will assert PTT on Winkey (all mode PTT) while MMTTY is
asserting PTT on DTR of the FSK port.
You can check to see if it is the all mode PTT by temporarily setting
the WriteLog port to 'None' in Router's Ports tab.

Hi All
I played as well in the SPDX RTTY contest (as part of VE3FJB) and I can
support the observations of Gary regarding PTT delays. It is quite
noticeable.
I am running writelog 11.11c, both 2Tone & MMTTY through XMMT.ocx, and a
Flex 3000 connected through DDutil. We just upgraded to 11.xx version of
Writelog prior to this contest and we were using this as a shakedown
contest.
Prior to the changes, we were running a version 10.xx Writelog with the
MMTTY plugin. No delays in PTT and it was snappy with the Flex / DDUtil
combo.
Based on this info, I did notice in the contest that some stations I
communicated with had longer turn around times - quite noticeable - and it
does make one ponder were they using Writelog?
Please view my feedback as constructive. Writelog is a super great
program. We are not straying. We did make some 300 contacts in SPDX in a
mostly search and pounce operation.

I've been struggling to make a few QSOs in the SPDX RTTY contest and band
conditions are simply awful. However, it is providing a bit of a test bed
for
the new XMMT.ocx interface. I've been noticing two things on transmit.
One,
in the main Rttyrite screen that prints in blue italics text, my macro
messages print erratically. Sometimes they print out character by
character,
as with the MMTTY plug-in, other times the entire macro dumps onto the
screen
as soon as the F key is pressed, and still other times I see part of the
macro
print to screen, then a slight pause and then the rest of the macro dumps
onto
the screen. Both of my clone windows, one with 2Tone the other with
MMTTY,
print the macros correctly character by character. I don't know what the
problem is with the main Rttyrite screen, but it seems to be sending ok
despite the weird appearance.
On another note, I use the microHAM MKII keyer and router software with
my FSK
setup. It seems to me by ear that both the PTT lead and tail are longer
than
what I'm used to hearing with the MMTTY plug-in. The PTT tail seems
particularly long and I've tried adjusting that setting on the PTT tab in
router to no avail. Is there something in XMMT.ocx that is causing this?
Anyone else notice it or just me? I think I will reinstall the MMTTY
plug-in
and see if that makes a difference.
