While I agree completely with the point you are making - that 2.4GHz has congestion issues - systems that don't operate in that band aren't ever going to be budget. Economies of scale - that's why all the budget UHF is still channel 70. And I didn't know that digital systems were available in Ch38 - I know of systems using 1.9GHz, and that might be a better bet. 2.4GHz will still be where all the cheaper stuff goes, though. Interesting that this Trantec seems to be specific frequency, rather than the Line6, which I think is frequency-hopping? That's going to make the Trantec rather vulnerable, I would have thought.
