|
Hi.
I have a Yaesu VXA-100 and the Yaesu external headset adapter cable. The standard PTT switch (which works fine with other radios & intercoms) does not work on this handheld/cable combination. It does not trigger tx.
Is anyone out there using a Yaesu handheld radio with an external PTT?
Do you have a wiring diagram that shows how to hook in an external PTT?
Thanks.

Bob,
Yaesu tends to use standard connectors, so the pinout diagram for their standard 8 pin microphone connection should work in your case. Luckily, Yaesu makes ham radios as well, so several ham sites have pinout diagrams for their radios. Try this link. The 8 pin diagram is the second entry in the table of contents. Hope this helps.

These people may have to info or what you need, Bob.

I've been running
a Yaesu vxa-100 for many years in my current ride but I cannot
remember exactly how I got the PTT to work. There are only three inputs to
handheld though, antenna, external power and the Headset adapter line
wherein I think you'd find the PTT attach point. I think the PTT line just went
from the adapter to the switch and then to ground. They've got the headset
adapter thing for $44 but may part with the info only if you've got the plug etc.
By the way, my old vxa-100 is the aviator PILOT model with VOR capability
so they said. What Yaesu did not tell it's customers is that the VOR
capability only works from a vehicle in a stationary postition. Kripes.
When we bitched vehemently to their head office in California, they advised
that an acceptable solution would be to take the unit back to where you bought
it and upgrade (at your own cost) to the next higher model. Hmmm.....

I am using the VXA-700 and it has its own screw in micro connector that goes
from the radio into an RCA coupler/splitter, which then goes into a FlyteCom
mixer box, and then to a separate push to talk.
My two cents worth.
It would not work with other set ups, or with Dave Clark helmets, only the
Fcom set up.
