Q: Will this work with the Yaesu FTA-550 Handheld ?
A: Yes, this will work with the headset adapter supplied with the FTA-550.
Q: Will this work with a vertex standard handheld transceiver?
A: Yes, this will work with the headset adapter that is used for the Vertex handhelds.
Q: Will this work with Sigtronics Trans com II?
A: Yes, this will work fine with your intercom.
Q: Is the Pilot USA 50 PTT compatible with my new D/C H10-13.4 Head Set? My radio is IC-A22 Hand-Held. What is the length of wire as I use it on the control stick.
A: Yes, this is compatible with the H10-13.4, but not with the IC-A22. I would recommend the Icom Push-To-Talk (PTT) for use with the IC-A22 transceiver. You can then use the headset adapter (OPC-499) that came with the radio to connect your H10-13.4 and Icom PTT directly to the radio.
Q: what size plug is on the male and female end of this push to talk?
A: The plug is a PJ-068 plug (described here) which is .206 inch / 5.25mm. The female is a S830 jack.
Q: Will this PTT work with ASA, DC, and Boz headsets?
A: This will work with any headset that has the dual plug connection (PJ-068/PJ-055B) for fixed wing.
Q: Will this work with Vertex 710 transceiver?
A: Yes it will.
Q: Can I use this PTT with an Icom A5 radio ? Thanks
A: This PTT would not work with your Icom IC-A5 transceiver. You would need to use Icom's Push-to-Talk.
