Joe and Bob,
I decided to chop things up to see what was inside. I found a
surprising result:
The microphone wire is a two-conductor wire, consisting of a single
insulated conductor and a shield. At the microphone XLR end the single
wire is connected to pin 2. At the rig end, this same wire is connected
to pin 1 of the eight pin connector. At the XLR end, the shield is
connected to pin3 and pin 1, while at the rig end, this shield goes to
pin 8. I know that audio gets to the rig with this setup, but it
clearly is not what you guys are talking about.
I see several alternatives:
1. Remove the shield connection to pin 3 at the XLR; leave pin 2 connected.
2. Remove the shield connection to pin 1 at the XLR; leave pin 2 connected.
3. Get a new cable with two or three conductors inside a shield and
still use only pins 1 and 2 at the XLR, using only conductors, not
shield.
4. Get a new cable with two or three conductors inside a shield and
still use only pins 3 and 2 at the XLR, using only conductors, not
shield.
Alternatives 3 and 4 leave me the choice of connecting the shield only
at the microphone end, or not, depending upon what works best at
reducing RFI.
I think that this exhausts the alternatives, so if one or both of you
can give me a shove in a single direction, I may be able to row out the
rest of the way by myself.
I gently patched things back together so I can meet my 2000Z sched, but
I await further instructions, O Masters of the Universe.
Your obdt. svt,
Jan, KX2A
