To help them understand, the "drive" and turn on are key.
When you say it sounds compressed, there are several things to consider.
One main one - to think about (how it all started), when they brought it in, was anything wrong with it and what has been done to it since then?
Palomar "Max mod" is simply an oversized part to fix a previous problem of using the undersized part to fix the problem of being the undersized part so they could sell it legally - now fixed with a bigger part.
- Similar to buying the car, them throwing away the 4-cylinder engine and dropping in a turbo;d version with a lot more spark plugs in it.
If you can understand that approach, they simply put a bigger band aid on a condition most radios face - overzealous AMC/ALC and not enough room for voltage swings because the current demands wash all those nuances away.
Flames have erupted when people start showing others how to "defeat" certain key things because they are the ones whom suffered thru the neighbor's party hut house key downs that rivaled "Worked All Neighbors" Awards -shows which were held in January, right after the Oscars - and before the Enemies - Er - Emmy awards...

"Gosh Darn It!"
But to see / hear this, means that you might have to put it back on the table and check the output network - there are one - sometimes two, caps on the tank coupling circuit from the MOSFET to the 52-MHz trap if one failed - you'll get a difficult child to play with and the SWR meter won't show any trouble because the problem is BEFORE the SWR meter (Upstream from that riser card) The SWR only shows the conditions PART itself into the outside - not before itself.

But there is also some hope in listening - but also comparing - try different power Trim levels thru the AM power control trimmer inside - then look at RF power controls and AMC/ALC - and even see if the Limiter - if it's in place - take a look around here for recent threads (86V I think) has uncovered some tweaks we aren't proud to disclose, but it does help those that want the limiter in place - just not clamping their audio.
Thinking of all the directions to take this...I'll spare you the LONG list and try and post a few smaller digestible sections so you don't turn this into a gluttony of gibberish most would have to invite interpreters over to "understand".
Bear with me...
It will be a ride - in small cars, with breaks to let the kids and old-folks use facilities...
