Re: GPS and RTH question

on frsky telemetry you have almost EVERY THING for an OSD/RTH system! Exact... almost! But as there's no straightforward way to add what's missing... so there's little point. introducing voice to the 9x is not straightforward. so there is little point on doing it ? If you like, go the all working a...

Re: GPS and RTH question

please note that I want the OSD system to be on the radio transmitter side... but that is me... probably most users will never even consider it. OSD is the only "thing" we can't do with that board (yet) it has to use a external chip. no worries there. its just an idea for now...

Re: Audio (voice) - Stock 9X PCB

the sound module used on the stock board always goes to 0 after the sound ends. therefor, my simple passive circuit cancels out any pop's when using an amp. I did my research and tests so it is there to be used. I'm sure I will. I don't like the internal amp of the module.

Re: Audio (voice) - Stock 9X PCB

its been said that the circuit with muting transistors does not suppress the pops and clicks. it should help but the only problem on the "pop's" side, is a half the sound module output DAC being shut-down to 0 when the sound stops. so when it powers up, the capacitor charging does make a &...
