Re: Do the XD-V75 ALWAYS have 14 free channels ALL OVER the world?

The short answer to the question that heads this discussion is "Yes", Jon...
...Provided you insert the critical word "license", ...14 license free channels all over the world.
In commenting I feel that I should first point out that I've no association with, nor particular loyalty to Line 6, (click the pink avatar for more details of my background) so anything I write here is the opinion of a Line 6 "fan" who now bases most of his location work on nine of their 2.4 GHz wireless systems.
So it's my opinion that, as clever as Line 6 undoubtedly are, maybe the "always available" claim they made in the past was just a bit too clever !
Always available ? ...Definitely. Usable ? ...Er, ...aah, ...um, ...probably 95 to 99% of the time, ...but not always !
To the "Danish Disaster". (I really feel for you. I get a knot in the stomach just thinking about having to suddenly re-rig everyone back to cables...)
In my experience, there's simply no way the crowd's (or band's, for that matter) cellphones or anybody's walkie-talkies could generate the six-channel "swamping" that you've reported.
Nor do I think Denmark's in any way to blame.
I'm almost certain that you had the misfortune to locate your G30 systems really close to (within, I'm guessing, about 10 metres of) a constant source of 2.4Ghz radiation, such as
- An in-house wireless data feed (such as are used for remote control of security systems, display systems, lighting and/or distributed audio) and/or
- A microwave link and/or
- An internal WiFi network base station and/or
- A wireless router.
Now for the really, really good news...
The purchase of just one XD-V75 system includes a complete, easy to operate "toolbox" for managing R.F. spectrum, including that occupied by your existing Relay gear.
So, should you ever be unlucky enough to again have a "Denmark situation", the V75 receiver's front-panel would not only immediately flag the potential problem, but would also facilitate a range of solutions, be they physical, (relocation) or electronic (re-tuning to channels shown to be free).
(It's important to note that you'd need to run the V75's "RF1" frequencies whenever you employ G30's in the same venue.)
And YES, I've found that that my eight XD-V70's (upgraded to V75 firmware) and my one V75 perform superbly all over the world, from Tasmania to Turkey.
I hope, however, that this conversation has somewhat reduced the overall urgency, ...in that, on arrival, you'd now conduct an immediate search for 2.4GHz "bandit" antennae, before the dreaded "Danish Red Light Syndrome" re-appears.
