A couple of comments related to this discussion. #1) I'd be surprised if the cost per unit of certifying a radio for the FCC adds more than a dollar to the unit cost. Based on this site (and others), the cost of getting a radio certified looks like it is usually under $5000 #2) As to the difference between two, otherwise identical, radios. One being Part95E certified, the other Part 15 or Part90. My guess is the only difference is operational limitations to conform to the Part95E rules. I really doubt there is any difference in the actual transmitter or receiver circuitry. So, If my second comment is accurate, and the two radios discussed in this topic are truly identical (other than changes to comply with Part95E). there is no way anyone listening could possibly know if you were on a Luiton LT-590 or a Midland XMT400. YMMV
