I believe this is the test results.

Interesting. Thanks for posting.

It is easy to get mired in the minutia of the FCC rules and find that key rulemakings and deadlines are not apparent. This archived page from the FCC rules 'splains the FCC narrowbanding deadline which passed back on January 1, 2013. From that date forward, 25 KHz operation on the Part 90 VHF UHF bands ceased to be permitted.
"After January 1, 2013, licensees not operating at 12.5 KHz efficiency will be in violation of the Commission's rules and could be subject to FCC enforcement action, which may include admonishment, monetary fines, or loss of license."

Should note that bandwidths an excess of 12.5 kHz can be applied for if used for data application.

Oh Wow, I didn't mean to embark so deeply on this subject--
.
,,,,,,but at the outset, this Johnson PPL of mine is not exactly the off-the-shelf Johnson PPL of yore. Anyone familiar with what lies beneath the radio's cover knows that there are certain little Pots that can be 'tweak'd", mods that can be easily preformed- that will easily drop a transmitter into the new narrow-band requirements....
.
That said, I go back to my original, somewhat rhetorical question.... Is once Type Accepted always Type Accepted?... Let me throw out this hypothetical--
.
Lets say I have an old GE tube boat anchor.... let's say, its on high band VHF. It was originally type accepted for Part 90--- Now, this nameless FCC licensed gnome turns down the deviation to make it fall within the new narrow band regulations- maybe add a audio filter here and there..... it looks compliant on my - ahh-- the Gnomes 'scope--- is it still Part 90 acceptable? On the the boat anchor's receiver such signals may sound weaker than 3.2 beer, but the receiver isn't the issue here. If it looks clean and legal on an external (FCC) monitor; is it not still legal under Part 90, -- frequency tolerances etc. all in limits,,,. all that aside.
.
This kind of attitude doesn't making selling new radios easier, but I would love to hear other's opinions on this- fact based or otherwise...citing sources??.... Remembering, I ask'd it (semi) rhetorically..... I really don't want to call the FCC.... I have this certain reputation...oh well.........

If the type certification didn't include the emissions designator that would work.

Its more simple- I've had it for years, it works great around my ranch, -- not to mention I hate being told to get rid of something perfectly useful. It must seem like I'm on a crusade here- well, hardly--
But I can see the heads shaking slowly as people turn and walk away, mumbling--
.
"What IS her problem?!"..... "get another radio, for crying out loud!"

It is not legal to modify an old boat anchor for narrowband (even though this can be successfully done with no problems) unless it has been FCC certified operating under those parameters. Now, having said that, if you have about 10-12K dollars laying around, you COULD send the boat anchor in to a independent FCC test lab. Be ready to do a lot of work (you'll need to produce modified service manuals, etc) but it can be done to obtain a new legal FCC cert. Is it worth it? Probably not.
Back in the day, Motorola used to make narrowband conversion kits for their radius line radios. Also, during the previous "narrowbanding" many MANY years ago, radios could be modified BUT there was a special sticker that needed to be affixed stating it was modified. Not the case today.
The new generation doesn't know the cold end of a soldering iron, but can write code to bust an ATM. Not sure anymore which is a more useful skill.
Ha, funny you mention that about the new generation. I just had this conversation today with a coworker of mine. It is sad, but true.
Anywho, to the poster who asked about modifying boat anchors, what once COULD be done relatively easily is no longer the case, legally.
