It's a "Snake Radio Custom". In my opinion, a clueless "screwdriver expert". Keep in mind Marc, the SSB power control in these radios is useless and no longer functional when the ALC transistor has been clipped out for "Maximum Swing" or whatever. ..and Jesse, If it were a clean 100, or even 500 Watts at 27 MHz, it would in no way harm the Motorola UHF front-end, however this thing with its un-filtered chinese-made amp slab is very likely going to be grossly dirty on the spectrum, so no promises. The only thing I can promise you is that no oscilloscopes, or spectrum analyzers, or professional technicians were used in the tuning of this "Super" radio. Quote from "the snake" himself from forums.radioreference.com: "I am old school and I tune and align the radios buy ear and my pep meter and my bird wattmeter and my signal generator and DB meter for receiver peak settings . I have had people take radio`s that I have done to other shops with all the spectrum analyzers and scopes netc etc put my radio on there equiptment and it was right on the money." Sure, I'll bet. I ran a CB shop in Salina Kansas back in the 80s and early 90s, and I have seen and repaired thousands of these butcher-shop customs. These days it is even worse with the influx of cheap Chinese and Italian MOSFET amp modules. If you are really worried about your UHF being overloaded, use one of these filters between the output of your CB amp, and your CB antenna: https://www.dxengineering.com/parts/mfj-704 That will filter out anything above 40 MHz to protect your other VHF and UHF radios, and prevent interfering with other services. It's a pricey accessory, but it might be worth if for you, and it will certainly handle all of the power you will be able to throw at it. Be sure to use a high-grade RG-214 coax jumper between the amp output and this filter. OK, now that I have upset everyone, I'll sign off for the day.
