[RTTY] MMTTY & Icom IC735 Linkage

You might try making a "Y" connector at the speaker output and hook that up
to your computer. I used to run a FT-840 on RTTY and it had an af output in
the back, but it wasn't enough to do the job properly.
Also, on the MMTTY setup, you need to have the program setup for AFSK or
FSK, whichever mode you are going to use. I would imagine that the IC735 is
set up for AFSK.
Also, there is an option to setup the input and output volume of the
program. Go to option/setup sound card input/output. Also, you need to
click on the volume control on the computer and see where the volume is set
there. Sometimes that is set to "mute" and it won't work right either.
Good luck and hope to work you on RTTY.

Subject: [RTTY] MMTTY & Icom IC735 Linkage
I'm new to this list, so apologies if this subject has been covered
I'm also new to the world of RTTY, please be gentle! ;-)
I've downloaded the latest version of MMTTY, and plan to use it with my Icom
IC735. If my 'toe dipping' into RTTY gets me hooked, I plan to buy a
suitable interface, but I thought that I'd try a simplistic method first, to
whet my appetite.
The software loads nicely without a problem. I can't get the laptop to
communicate with the rig, but I'm not too bothered about that aspect, as
such. I've made a connection cable to go between ACC1 on the 735, to the
appropriate sockets on the laptop.
With quite an amount of volume from the rig, certainly more than can be
tolerated on speaker, I can get reasonable decoding on the laptop. I had
thought that the audio was a 'constant' output which was independent of the
volume control - but maybe not? No amount of output from the laptop
activates the VOX on the rig, so I'm assuming that the ACC1 Socket does not
tie-in with the VOX. With the TX button depressed to force the rig into
transmit, the rig still gives no RF output. I've checked the RF gain, MIC
gain and cable connections. The rig works perfectly with the microphone.
My next port of call is utilising the microphone socket to give the required
connectivity - has anyone had some prior experience of this please? Is it a
simple case of wiring a suitable plug or is there anything I should be aware
Thanks for any assistance!
