I have a fetish about reducing the number of cables. When I built my
latest SO2R box in 1996, I used six conductor cable (3 individually
shielded pairs) to provide MIC/MICgnd, PTT/PTTgnd and
HEADPHONEleft/HEADPHONEright. This single cable came from the box to the
mic jack on the front of the FT-1000Ds, with the headphone broken out with
heat shrink. This worked out really well and was very easy to deal
with. However, I gave the whole setup (box and cables) to W8MJ a year ago
because he was doing more SO2R than me. Now I wish I had it back.
Some people would rather have separate jacks for each function because then
there is a possibility of using pre-made cables. Like my friend K9TM says
- there are better things to do than make cables. This has been the
sticking point for producing a second-generation NA SO2R switching board -
its hard to reach a concensus on the connectors, particularly when PC-board
mounted connectors are desired. It will be interesting to see what Array
Solutions uses on their SO2R box.
