ow hard would it be to wire up a third-party mic to an htx-252?

tia!

------------------------
Uses the common condenser mic / 2k to ground ptt circuit.
I use mine as a NCS station and wanted to use a headset so I
drilled a hole in the rear of the mic in installed a 3/32'' jack.
this allows me to use the regular mic and when I want to use my headset i just
plug the headset into the mic and the plug for the earphone into the extspk
jack(optional). I use the RS headset 19-312
which can be had at RS on closeout for $10.00. These headset are nice because
the plugs aren't siamesed and fit many different handhelds and do vox also.The
ptt is mounted on my clipboard so I can key with my left hand and log with my
right (sitting in my easyboy).I get many comments on the great quality of my
audio.
I have a link to the schematic for the htx-252 available on request.

- just a quick question:

how hard would it be to wire up a third-party mic to an htx-252?

the htx-252 pinouts are available... AFAIK, no audio is sent to
the 'standard' mic...

oh, and i don't care about DTMF, although i do have a spare
yaesu DTMF on hand...

if anyone has done this i'd appreciate a tip or two!

tia!
This is kind of a late response to your question, but it is not too
hard to do. I built a little adapter box with a 5 pin DIN jack on one
side and a short 8 conductor cable with an 8 pin mic plug on the
other. I have 6 push button switches wired to replace the radio
control switches. I have a .22 mfd cap in series with the audio lead
to the mic. Keying is a 2.2k resistor switched from the radio side of
the cap to ground.

I have a Turner desk mic connected now, and it works. Just how well
I'm not sure. Around here no one complains unless you are totally
unintelligible. So far I haven't touched the deviation limiter pot.
