I've had a rangevideo receiver & transmitter (both no longer for sale on the site) for just about a year, and have used both some but always been very careful to keep them dry and protected from trouble.
Everything worked great yesterday....
But today when I turned it all on to show a friend, all I could get on my feed was garbage! Later at home with some poking around, it seems that something has happened to whatever thing handles the channel separation inside the RX. All RV units ship to work on channel 1 (910mhz), and that's what has worked over the last year.. except today, I could only get garbage on 1 and parts of a picture on channel 2 (980mhz).
If I use my patch antenna and keep the tx within 4 feet, I can get an ok picture, with some artifacts. The whip needs to be much closer. Compare this to a few days before, when I was out 2500 feet without issues...
Incidentally, the separators on that channel switch feel pretty weak, like the little cams that lock it into each position have given up a bit. Which is interesting because I've never really moved them more than twice, ever.
Here's video of some bad radio:
Here's what it looked like before this mess (for this, a direct cable connection is used):
The $65 + shipping RV is asking for the only receiver they carry now is way out of my budget, unless I get rid of my plans for the tricopter, which would be quite unfortunate.
I'm pretty handy with a soldering iron... or if it's not fixable, can anyone suggest a new RX that works with my existing patch & 900mhz TX?
I should mention that I've tried powering the vRx with two separate 3S lipos (both full) and a 12v 500ma wall adaptor. The vTX rig has been powered through a 3S and an 800ma wall adaptor. Directly connecting the rig to the recorder reveals a perfect picture. I've tried a normal whip & a +3dbi on the vtx & receiver. Also a patch on the Rx. The videos are shot with my last known working configuration, a +3 on the vtx and the patch on the vrx. The units were are about 5 feet apart during the videos (uploading now).
