I made a short video of a vintage Realistic TRC-422a from the late 1970s listening to incoming skip on channel 13. Hear anyone you know?  This radio featured both ceramic and crystal IF filters. The adjacent channel selectivity listed in the owners manual is 80db @ 10 kHz! The actual receiver performance shows a better than average ability to reject bleedover compared to most CB radios. The receiver is located near Charleston, South Carolina. www.youtube.com/watch?v=8T1G1Mbweq0Night Ranger |

Back in the day, most of us poo-poo'ed radios like the TRC421 and 422, for the simple reason that they were the first batch of radios with "unmodifiable" PLL's. Back then, the primary measure of a radio's worth was how far it could be modified to move. Radios like the TRC-457/458, and the Lafayette Telsat SSB-140 were highly regarded in that department. It's a shame really, some of those "unmovable" radios (like the TRC-451), performed very well otherwise on the legal channels, but were never considered due to PLL restrictions. Since the object of focus has shifted, some of those originally ignored radios have been rediscovered for the sound designs that they had. |

I actually recorded about two hours worth of video gate, but after the last transmission on the video I uploaded Pennsylvania faded out. I'll turn the camera on again if I hear Pennsylvania coming in this weekend. Night Ranger/South Carolina 116 on sideband |
