They were great radios in the day, but not broad banded. Mine was tuned to 440-450 ham freq’s. Worked great. But every year when the fair came to town, I’d be on their 468 freq’s working in the parking lot. The fair didn’t have enough radios to go around, so we were told to use our radios. But it’d be pretty deaf at 468, so I’d retune it. Simple, & took a minute. After the fair leaves town, retune back to ham freq’s. I told a buddy who worked for Motorola in Plantation, so I met him there on a Saturday, & we went to his work station where he retuned it to work well at 440, & 468. It was a compromise, but seemed to work OK on both. Today with the newer radios doing the entire UHF band, I won’t even waste money buying a battery for the radios I still have. Oh, the volume, & channel knobs have disintegrated into a white dust years ago.
