Hello.
I've bought my unit from bangood. It was about 1/2 year ago - but I was able to test it only recently.
Anyway.
My setup:
EZUHF radio
1.2 video
skylark tiny osd

photos of video system (just in case): https://imgur.com/gallery/Pi8ry
I've flashed latest firmware from official website.
Wiring is 100% correct.
1) GPS signal is weak no matter what I do
I've tried with video Tx/Rx on and off. I was waiting for like 30 min - but the result is the same - 0 satellites.
I've tried 5.8 video - same result.
I have not tested it outside yet, but I've tried to put it onto balcony - same result. And as an example - naza finds GPS in my apartments very quickly.
Q: Any ideas what should I do b4 ordering new GPS unit?
2) RSSI readings.
I've turned Link Quality on CH8 in immersionRCtoools settings.
Calibration was successful.
It works but in a strange manner.
When I turn transmitter off RSSI 1st drops to 53% and after a tiny pause - about 1/2 - 1 sec it goes to 0.
Q: Is it normal?
