SUCCI-R Rig control, CW and PTT

Bought one of these as my Microham cw keyer is a bit bulky and expensive for portable operation. I planned to use my K2 from the car for CQWW CW 2013 using the call MM3T. I have in the past experienced QRM from using USB to serial cables. The SUCCI-R uses a noise filter on the serial link and opto-isolators on the CW and PTT lines to keep noise to a minimum. Cables are simple to make up (same as cw keyer). My location was picked for it's proximity to the sea and height above it. Being very remote I had no QRM so could give the SUCCI-R a good hammering in the contest. After 10 hours of contesting with 400w and a vertical antenna right next to the car, I realised that the SUCCI-R had just worked with no noise, lock ups, corrupted keying or odd buffering that I have experienced with other interfaces. Just brilliant and I can highly recommend it. It's very well put together and required no extra driver Polava when connected to a windows 7 laptop. Work seamlessly with Wintest contest logging software.
