[Yaesu] VX-5R speaker/mic pin out

[Robert Meier]

Mike,

> Can anyone give me the pin-out of the 4 conductor speaker/mic plug for the
> VX-5R HT?

   tip 1 speaker (+)
       2 TTL bidirectional data (+)
       3 Mic/PTT (+)
shield 4 ground (spkr -, mic -)

speaker: 16ohm
mic:	 electret in parallel with 1nF and in parallel with 2.2K 
ptt:	 normally open in series with mic



I'm looking for an inexpensive TTL to/from RS-232 level converter with
screw or mini/micro connections that I can use with a VX-5R and other
programmable equipment.
