Check this out if you have a Garmin GTR 200 or 200B com radio

Keith Klos All Messages By This Member #90104 The GTR200 and 200B has the ability to configure one of the 2 soft keys to work as a PTT button in case your one on the stick fails. I guess I knew this when I first got the radio but didn't configure it until I started looking at my little "micro switch" on the stick for PTT. I realized if that fails, I might have a problem transmitting. It is VERY easy to configure that soft key as a PTT function. Just go to the configure menu (access by powering up while pushing the small knob on the right side). Select "soft key configuration" and select PTT and then go "back" and then shut down the radio and power back up. Since the little PTT switch on my sticks just grounds a wire, I am guessing if it failed in the grounded mode then the soft key would not work and all we would get is a notice of a "stuck mic". But if it failed open then the soft key would work great. I hardly ever use those soft keys so this was a no brainer for me. Just thought I would let everyone know that it is a nice function should you need it. ? Keith
David Lamphere All Messages By This Member #90105 开云体育 I actually had a stuck (to ground) PTT problem! Couldn’t use the passenger PTT - the TX is stuck on. Solution? Pull the fuse/breaker for the radio and grab your portable hand held radio (if you have one) and use that.

Keith Klos All Messages By This Member #90106 Dave, Yup that is the only solution that I can think of if it fails in the TX? mode.? ?I tried to protect that wire from chafing in any areas where the stick moves (wire comes up through the stick) but I am sure it could happen. thanks Keith
Karl Wittnebel All Messages By This Member #90107 The 200b is great and the intercom works well and if you pair it with an aera 660 it will preload frequencies into standby from the map touchscreen toggle quoted message Show quoted text On Thu, Mar 27, 2025, 07:04 Keith Klos via <kloskeith=[email protected]> wrote: Dave, Yup that is the only solution that I can think of if it fails in the TX? mode.? ?I tried to protect that wire from chafing in any areas where the stick moves (wire comes up through the stick) but I am sure it could happen. thanks Keith
Brian Bird All Messages By This Member #90108 Maybe carry a pair of dikes with you in case the push button sticks, you could snip the wires. toggle quoted message Show quoted text On Thu, Mar 27, 2025 at 5:08?PM Karl Wittnebel via <dr.wittnebel=[email protected]> wrote: The 200b is great and the intercom works well and if you pair it with an aera 660 it will preload frequencies into standby from the map touchscreen On Thu, Mar 27, 2025, 07:04 Keith Klos via <kloskeith=[email protected]> wrote: Dave, Yup that is the only solution that I can think of if it fails in the TX? mode.? ?I tried to protect that wire from chafing in any areas where the stick moves (wire comes up through the stick) but I am sure it could happen. thanks Keith

tim mikus All Messages By This Member #90110 FYI, the GTR200(B) has a stuck mic feature, it will return to receive mode after a 35 second transmit and give you a stuck mic key warning after which you can use the programmed soft key to transmit normally.
Keith Klos All Messages By This Member #90111 Tim, Thanks-so if your mic switch on your stick grounds out,? the GTR20(B) will "bypass" that mic connection (after 35 sec) and just allow you to use the soft key?? Wow that is great.? Makes perfect sense and I wouldn't think that it would be hard for Garmin to do via internal software.? Just make the mic wire pins on the connector "inactive" when a stuck mike occurs and revert to the internal soft key.? ?Very clever.? Not everybody has access to clip the mic wires in flight in the case of a stuck mic.? ? I am impressed. ? Thanks for sending that info Keith
Keith Klos All Messages By This Member #90112 Tim, I just looked at my manual for the GTR200 and GTR200B.? I appears that my GTR200 also does what you described.? ?I can't believe I overlooked that feature. ? Thanks again.
