I guess anything's possible... but I'm not buying that answer so quickly.

It sounds like you're telling us the module is getting almost HOT to the touch, and
everything works fine until it gets hot, but then it starts flaking out, until the
module cools off for a few minutes... and then everything is fine again.
Then, after a bit, once the module is hot again, it starts flaking out again.

If that's an accurate assessment, I wouldn't put too much stock in their answer, just yet.

Definitely find another brand receiver to verify against...
but it seems that if there were any incompatibility issues, they'd show up
whether the module itself was cold, hot, or anywhere in between.


Better yet... if you know a HAM operator, with a spectrum analyzer, let him
take a look at this thing, to see what's going on with it, when it heats up.


Clarification: If Hitec is saying not to use this system with specific receivers, then you
should certainly choose a different receiver. I'm just saying, "if it acts differently,
according to how "hot" or "cool" the module is, then it sounds like you have other issues.
