Perhaps they're just using the RCA shells as a handy cover for the capsule.=
I just measured one at about 8 or 9mm across. I know the EM172s are about =

If you can twist the pre attached wires to your cable then it should be qui=
te safe to solder them as well. It's only when you get close to the capsule=
that you need to be quick.=0D
=0D
You need to be very careful not to put any strain on the pre attached wires=
, as they're thin and can break off. I had to take the plunge and re solder=
one of mine.=0D

I initially used a cheap 3.5mm-3.5mm cable I had lying around after cutting=
one plug off, but found that it wasn't well shielded. I started a thread a=
while back to try to work out why I was getting bands of harmonics on my s=
pectrograms. The source was the Sony M10's display, made very obvious becau=
se I initially had it too close to the mics.=0D
=0D
But even a metre away, the bands were still faintly visible. After I replac=
ed it with thick braided cable and plugs with metal shells, it was fixed. I=
suspect the interference may have been entering the cable near the plug at=
the recorder end, or maybe even via the probably unshielded wires inside t=
he plug itself.=0D

David, I ordered the mic capsules from Frogloggers, and while the Primo sit=
e does not show those caps as wired, they came that way. Either Primo does=
that, or Gene, but either way, I plan on using the existing wires so as to=
avoid having to solder the caps themselves at all! That's why I was aski=
ng about just twist wiring...if I can avoid solder altogether, given I've N=
EVER soldered anything before(and which may be my issue with my other mics)=
I will. On another list, there are several references to glueing mic cap=
s to plugs(RCA in this case, but there were a couple of other references to=
gluing). I'm wondering if you could just twist wire the mic cap wires to=
the wires of the cable, and glue over them for strength. If they are alre=
ady twisted, that should not effect conductivity and it might be a better w=
ay then soldering for a complete rookie such as myself! I may try that...=
I can always just cut the wires shorter and star again if it=0D
does not work=0D

I use 3.5mm plugs and sockets for recording bat detectors becaues that=0D
is how they are wired. I use 10 metre extension leads rather then=0D
permanently long leads but the problem is that these plugs and RCA=0D
plugs can easily pull out. The answer with a junction on an extension=0D
lead is to tie a half knot at the joins so the plugs pull togeher=0D
rather than apart.=0D
=0D
If you use long leads for stereo or two track like my bat detectors=0D
you can get a bit of cross-talk from a combined cable. I either use=0D
individually screened conductors or figure-8 twin screened cable.=0D

My soldering tip again - use extra flux when soldering delicate=0D
components and you can do the joint almost instantly. Most components=0D
allow for a second or two soldering time.=0D
