While on the subject of PC RTTY this is the interface that I use going between laptop and 106, or some of the bigger systems at home and Harris radios. Now days use a Dovetron modem connected to the big Harris setup and that’s all balanced audio from the home QTH but at this time cheating and using the Toughbook, interface and GRC-106 in the field but hope to be getting a UGC-74 and MD-520 together over the winter and take mechanical teletype show on the road this spring.

I have used MITTY 1.68 on a Panasonic Toughbook for some time now, uses the regular PC audio card, the RTS for controlling the transmitter and will do any shift including 850 Hz. That’s the set up I use for running RTTY from the mutt with the 106 like at Gilbert.

It’s a free ware program and can be easily set up and used. I am using it in the field running an old laptop and windows XP.

Gang,

Is there any PC software that supports the military (?) standard some of our guys are running on the air?
