I was wondering if any of the Hams out there have any knowledge of the modifications required (to the Swan 500) to allow the VX-2 to work CW "break in" with my Swan 500.
I am sure it can be done, but if no specifics arrive you might compare your 500 schematic with the 500C schematic and concentrate on connections to the VOX socket. I suspect something might be connected there on the 500C that was not there on the 500, but I don't have a 500 schematic to compare. I am curious about the parts connected to pin 5 that also connect to the keying line.
Here is 500C infornation including the schematic at the end. http://gmcotton.com/Ham_Radio/MISC%20Ma ... Manual.pdf
