[WriteLog] Writelog RTTY-->Remote Rig-->K3/0

[Ron Lodewyck]

I am trying to use Writelog with MMTTY to operate FSK RTTY via remote 
using the Remote Rig RRC units and the Elecraft K3/0 to K3.  I have the 
K3/0 Control, K3 Remote, notebook computer connected via hardware COM 5 
to Control RRC COM1 and the RRC 1258 MkIIs units working fine on SSB and 
CW.

I also have MMTTY standalone working OK with the following setting:
TX-->PTT&FSK -COM9 (which is my COMFSK port as seen in Win 7 Device 
Manager)
Radio Command -->PORT = NONE, DTR/RTS PTT checked
When I click TX on MMTTY's Main Panel, the K3 transmits FSK generated 
RTTY AOK.
when I click TXOFF, the K3 returns to receive as expected.

So far,so good.

When I open the RTTY window in Writelog and select
MMTTY as the TU Type,
COM 9 (recall this is COMFSK) under 'Port',
and, under Setup-->Ports, COM 5 (a hardware COM port out of my laptop) 
as the Elecraft K3 port,

I get the radio frequency and mode displayed OK, but the PTT and FSK 
keying are both flaky.  By that I mean sometimes I can key the 
transmitter, sometimes not.  Usually it keys the TX on but won't return 
to Receive.  The typed text might send a few characters OK, then stop 
and send a steady carrier and then, after 10 or 15 seconds (sometimes) 
it continues sending what is in the typing ahead buffer.  I can almost 
never get the radio to return to Receive by typing Alt-K (keyboard 
typing on/off toggle) and I have to hit ESC -several times.   Sometimes 
I have to close the RTTY window completely to return to Receive mode. 
And a couple of times I had to actually power down the K3/0 and K3 to 
get out of transmit.

I suspected RFI, but, recall, everything works fine with MMTTY 
standalone.  And, I turned the output power down to less than a watt and 
no change in behavior.  So I don't think this is an RFI problem.

Has anyone ever gotten Writelog to work FSK RTTY with the K3/0, K3 and 
Remote Rig? I'd very much appreciate hearing from anyone who has.  I 
suspect the problem is in the COM1 and COM2 port settings in the CONTROL 
RRC Web Server settings, but I've tried just about everything to no 
avail.  Or, possibly the problem is some combination of Writelog 
settings that I just haven't got right.

I can really use some help.  Thanks and 73,
