I use the radio for paragliding and the radio is mounted on a "cockpit" in front of me when flying.
When in flight my hands are busy. I can hear the radio fine (don't need an earpiece) and I can transmit fine too (others can hear me, don't need a better/closer mic).
However transmitting can be problematic because I have to take one of my hands off the controls to press and hold the PTT button on the side of the radio.
My idea was to use a kenwood type cable and connecting a button/switch to the correct terminals so that I can put effectively the PTT switch about 50cm away from the radio where I can push and transmit without taking my hands off the controls.
If this is possible, which two terminals would I be shorting?
As a bonus question, would the UV-5R support dual PTT (A and B) like the UV82 described in the link?
Many thanks for the help
