Any info you can provide would be helpful. Honestly, I was hoping a quick email to Immersion RC would have gotten me up to speed on these things. But, it has only been 4-days, so maybe they will respond soon.
Since the 1W Tx came from you, perhaps you can fill in some of the blanks. Have you ever noticed if the mic input is more sensitive than the average Tx? That is, if you install a Tiny-Mic on it, is it louder than usual? Also, do you have any other customers using the Oracle with the EZTracker?
Maybe there is an issue of the 2 receviers being on different audio levels, when the EzTracker can understand one, the other one may be too faint or to loud to be understood by the EzAntennaTracker.
That would certainly be a concern. Everything is suspect, so I will add it to the list. But, this problem seems more odd than that, at least at this point.
