BTW, here's a link to a web site done by a DC comm's lawyer. Yes, he has the 'disclaimers' not to use it as 'legal advice', but you can beturbut it's right. <http://www.narrowbandinglaw.com/faqs.html> It's the second last question. There is a link in the answer to the FCC order involved, but of course it's filled with typical legal-ese...
One thing I am not sure about-I do remember now that there was a narrowband only version of the TK-x20 mobiles, along with a few other Kenwoods of that vintage-the model number had an 'N' on the end. I don't remember a TKR version, but there may have been. Those should of course be fine, because they started life NB. Also rx's are not an issue. Narrowbanding, say, an MII rx is fine, since the FCC doesn't care about rx's. It's only tx's that need to be properly type accepted.
