Hartwig 0 Posted July 15, 2007 Report Share Posted July 15, 2007 (edited) I got two brandnew identical Airwave TX612 modules which perfrom very well, but I got one problem: They have different sensitivity on their video input. While using the same receiver I get a little less than 1Vpp with the first module and about 1.1Vpp with the second. I heard rumors that the video level sensitivity of the modules can be adjusted using a little pot located inside the "sardine can". Does anybody know if this is correct, and if so, how to locate that pot? I don't want to screw up the precious thing by destroying a factory set parameter. On the picture, which I attached, you see the TX module with its upper lid taken away, so you can see the two pots that I discovered. The upper one, located at the upper left corner of the picture, is also accessable through a hole in the lid. Any help will be greatly appreciated! Thanks a lot in advance, Cheers, Hartwig Edited July 15, 2007 by Hartwig Quote Link to post Share on other sites
Mr.RC-Cam 129 Posted July 15, 2007 Report Share Posted July 15, 2007 Video level is at the lower left corner. Quote Link to post Share on other sites
Hartwig 0 Posted July 15, 2007 Author Report Share Posted July 15, 2007 (edited) Ah, great! Thanks! Do you have an idea what the other pot in the upper left corner is for? I actually supposed it would be this one because it's accessable from the outside Cheers, Hartwig Edited July 15, 2007 by Hartwig Quote Link to post Share on other sites
Mr.RC-Cam 129 Posted July 16, 2007 Report Share Posted July 16, 2007 It's for the freq Synth PLL. Quote Link to post Share on other sites
Hartwig 0 Posted July 16, 2007 Author Report Share Posted July 16, 2007 Is there any way to determine if the pot of the frequ Synth PLL is still correctly adjusted? I'm not sure if I accidently touched the wrong pot today and turned it back into its previous position... How does this pot affect the PLL? Quote Link to post Share on other sites
