I guess it depends on what you call 'tinny' audio.
To me, the true definition of "tinny" is when the Corps went from 3/4 PUs to Gama Goats. From an ordinary gas, 4X4, PU, that did the job, to a 4-wheel steering, diesel, 6X6, POS.
Come on ole timers, remember those amphibious turds that couldn't get you to the enlisted club? I remember one time we crossed a river to get to the gals. Next morning it wasn't just the Gama Goats that had the drip.
Sorry, since I'm retired, I use my PSR-800 and my time for disaster clean up. With the right antenna, this radio is a real workhorse. Cuz I never know where I'll be, the location based programming is as sweet as 2 funny boys with lock jaw.
