[Dx4win] MMTTY

[Larry Gauthier]

Bill (et al),

No, you do not need a TU - although MMTTY requires a single-transistor
circuit for keying the rig from serial port of the computer (MMTTY uses an
identical single transistor circuit that DX4WIN uses for PSK keying.

My installation runs DX4WIN with CW and PSK, and interfaces to MMTTY for
RTTY. All of this can be done in a single computer with a single sound
card - but since either DX4WIN/PSK or MMTTY/RTTY must "control" the sound
card, you obviously cannot have the DX4WIN PSK window open at the same time
you have the MMTTY software program running. You will get a message "Error
starting the soundcard: Device already allocated.". Since I never run RTTY
and PSK simultaneously (?) I do not see this as a disadvantage.

After two years of running MMTTY and four years of using DX4WIN, I have
managed to get the two working together in a way that best matches my needs
(your mileage may vary...).

1. FOR EVERYDAY RTTY RAG-CHEWING, I run DX4WIN and MMTTY as separate
programs. This means that I rely on the macros in MMTTY [which are more
plentiful and full-featured than those in DX4WIN] for my QSOs, and then
manually enter the data into DX4WIN for logging  - and simply live with the
inconvenience of manually recording the QSO info in the log. With this
configuration -- without any changes, adjustments, or plugging/unplugging --
I can switch between SSB, RTTY, PSK and CW modes. Also, by controlling the
RTTY QSO from within MMTTY, I have a much more pleasant "keyboard"
experience - with typeahead buffers, backspace/delete keys, and other
benefits.

2. FOR RTTY CONTESTING, I do not want to duplicate-enter data between MMTTY
and DX4WIN- I want high speed operation with a limited set of RTTY macros in
DX4WIN controlling the QSOs. To accomplish this, I cross-connect the two
programs inside one computer using the MixW null modem freeware that allows
two programs to talk to each other in/out a pair of phantom serial ports. A
disadvantage of this arrangement is that the keyboard functions
(backspace/delete, especially) from DX4WIN are a little funky - but as long
as you are only sending short bursts of messages and macro-controlled
transmissions, who cares? The big advantage is speed and simplicity -
logging, contest counts, duplicate callsigns, and macros are all driven from
one program - DX4WIN. In this configuration, MMTTY is used as a "background"
RTTY engine.

NOTE: The MixW null modem freeware only works on Windows 2000 and XP. If you
are running an older operating system you will need to have two spare "real"
serial ports to make MMTTY and DX4WIN talk to each other, using a null modem
cable (plus a third serial port for rig keying from MMTTY).

Finally - I have documented this configuration in a couple of files that
describe all the settings and the macro strings that I use. Send me an email
and I will gladly forward them to you.
