I’m facing this problem: I have a Skytraxx 2.0 (GPS variometer for paraglider) and a Puxing PX-888 VHF ham radio.
When the variometer emits sounds, it triggers the radio whatever the squelch setting is set on.
A quick video of the problem:
While I’m doubtful about the CE certification of this very cheap Chinese radio (a CE sticker is present in the battery tray but doesn’t mean much…).
So, as I’m not planning to change neither the radio or the variometer, I came along with this fix: put aluminum foil inside the variometer case.
Very easy to do, juste make sure the aluminium touches the usb connector when you close it and everything else is well insulated (pin with kapton tape, etc..).
Now the same test with the aluminium shield:
Much better: can use for competitions now, with the mini solar vario leBipBip.
It even seems to improve the time to fix, usualy took 5min and now about 1-2min.
