OpenGD77

Many external mikes are wired with the microphone ground connection connected to the PTT pin (Outer of the 3.5mm Jack). The PTT pin is connected to ground (outer of 2.5mm jack) when either the external or internal PTT is pressed. So the external microphone is only connected when the PTT is pressed....

YesI did see them, but my PTT is not triggered by RF and the audio only fed through only when keeping the PTT switch closed.
Also one of my GD-77 is connected to an external antenna with same symptom and the symtom is same on < 50mW RF with the antenna on the radio.

Hi folks, Has anybody come across this problem? External mic connected PTT latch enabled Pushing thr PTT either on the radio or external mic and release it => GD-77 transmitting but audio is not fed through to the mic amp (no audio on TX signal, no modulation bar) Repressing and holding the PTT or k...

Awesome,thanks
Sorry could have tried VFO mode but I don't use it therefore it dosen't come into my mind....

I downgraded to 1,60 and green short revert to zones.

Hi

Thank you very much for you effort

I notied that short press green leads to options.
At 1.60 it leads to zones which IHMO was more convenient.

Ah, this is great, thanks Mike.
I even like the double press organe, as I have one of my GDs in the car on the dashbord in the base stand, where it is musch easier to press on the top key than on front keys (usng the thump and one finger)

Hi Mike, Thanks. Wasn't it possible to return the long press up arrow in channnel mode to scrolling again, rahter than start scanning? I haven't had time to dive into it yet. So this build is just an update with the latest bug fixes and general code changes. This week I should be able to take a loo...
