Ok, at least its not an early 1970s vintage radio with the TO-3 final. I forgot they simply changed the circuit board traces around the transistor for the newer style instead of changing the entire layout. My memory is foggy but it seems like I had the mobile version of your business band radio set up on CB at one time. I also recall having the CB base version and didn't like it for some reason, but that must have been 47 or 48 years ago.

I haven't benched it yet but when I do I'll give you what it does on the IFR. Researching the MRF8004 the spec sheet calls it a 27mhz NPN PO transistor rated at a whopping 3.5 watts.....
