Dave,
There are plans afoot to be able to offer a bare PCB for the NA SO2R box.
Long time readers of this reflector will scoff at this, because I've been
saying this for over a year. We had a small run (5 pieces) of boards back
in 1997 which wound up going to W4AN, K3MM, N4AR, K9TM and K8CC (now at
W8MJ). The board worked perfectly - as W4AN said "You can't tell its in
the line on your SSB signal". However, it used chassis-mounted connectors
which made for a lot of hand-wiring. One goal of the new design is to use
all PC-mount connectors which will speed up assembly time.
K9TM and I have been brainstorming the new configuration, and have a new
configuration going on paper. Here are connectors we're thinking of:
Function Connector
----------------------------------- ---------------
Radio audio in, headphone audio out 1/8 mini stereo
Radio PTT out, PTT in RCA phono
Radio mic out, mic in 1/8 mini mono
Radio key out, key in RCA phono
Paddle in 1/4 stereo
LPT in ribbon cable to DB-25
If anyone has any suggestions, now is the time. Since I gave away my
original box, I now have new impetus to make this project happen before the
fall.
I know WX0B is planning to offer a SO2R box. Although he claims NA
compatibility, I've not seen any details. Its likely this will be an
expensive box - not that Jay is a crook, its just that low volume niche
products like this are expensive to make. While building your own takes
time, there might be a lot of $$$ to save.
