Well I did get the lead and software for the 5555 after all. What a game it was, or still is because i'm not finished yet programming it. Not used to TAR files and this is how the usb to serial driver was wrapped up on the disc. I got there in the end, more by luck than judgement and finally got the radio to talk to the computer. When I got the software to work I found I had the missing com port (3) available, whereas before com ports 1 and 2 wouldn't communicate *sigh*.
Have just entered portions of the band relevant to me, ie cw, ssb, fm simplex and the repeaters with shifts. I've tried cw at 5 khz steps and the rest at 10, leaving fine tuning to the 'clarifier' knob, which goes down to 10 hz anyway. Couldn't get all the ssb portion in the 60 channels available on one bank this way, so might spread the load over two banks. I'll leave it for now, i'm cream crackered. Play with it tomorrow.
