...Return it to the shop and never play wireless again...
As you have already found, Ruurd...
Your G50 is an absolute joy in nearly all
"normal" situations. I think you will agree that it would be a crying shame to no longer have that.
...or just not play wireless on a iron pontoon (another gig on the same spot is coming up in august..)
Successful wireless is
possible at sea. I know. I've done it many times, but never
without special preparation...
...So, if you still want
to go wireless aboard the pontoon...
...If at all possible, I feel that it would be vital
for you to do some testing on that same pontoon
before that next gig.
Rather than taking your instrument and your entire rig for that trial, I would suggest that you first develop a light weight "test kit" to carry with you.
I would do this by
- Arranging an adapter (or a series of adapters, if necessary) to get a reliable signal from your G50's output jack to either a tiny speaker or a headset or earphones and
- Experimenting until we get an equally reliable (and similarly adapted) signal from an iPod, iPad, portable radio or other media player (which would become a replacement instrument) into our G50 beltpack transmitter.
(The actual quality
of the sound from this arrangement doesn't matter, as we will only be testing for RF strength and continuous reception.)
So what we then
try is to find out what placement
of our G50 receiver gives the best reception (if any) when we are actually in the performing position aboard that pontoon.
The top row of three LEDS below your receiver's "CABLE TONE" are the main indication for this. We are trying for at least two, but preferably all three
to be lit, with the beltpack on the player. (You will probably need a friend to "stand in" as "the player", because you
will be busy moving the receiver around while listening and looking at those LEDs.)
If you place the receiver in its "normal" position on the deck, (on the "floor", next to foot-operated effects, for instance) that location may
indeed result in the pontoon's metal structure (being so close to the G50 receiver's antennae) absorbing, "earthing" or "garbling" whatever RF is coming from your beltpack, or that close positioning could even have caused the water and pontoon to combine
, effectively "making" a giant "concentrator" for whatever maritime RF is out there, "swamping" your poor little beltpack.
(Which is, sort of, what you originally thought.)
So experimenting to first find a spot that works ...and then going "back home" to figure out how to cable to and from whatever weird spot for your receiver actually gave reliable results in that "on board" test, ...is a technique that is fairly likely (in my experience) to grant "G50 freedom" at your upcoming pontoon gig.
