  1. 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.

    Newly Purchased ICOM FR4000

    NOTE: RG-400u is NOT the same type of cable as LMR-400 or DX-400. RG-400u is a smaller diameter, double-shielded cable, the size of RG-58u, for use as jumpers in a repeater system, or internal radio connections where signal leakage would be a problem. LMR400 from TImes Microwave and its clone, the DX400 cable from DX Engineering is a larger cable, the size of RG-8u, that is supposedly rated for use up into the 400 MHz range with low-loss. It has its uses, and can be great for a GMRS base station, but not a repeater where it has to transmit and receive at the same time - that is where the trouble starts. RG-400u, and its larger cousin RG-214u are Mil-Spec double-shielded, silver plated cables, specifically designed so that the signals between two closely-ran cables will not cross-talk into one another. That's what you need is a repeater system.

    GMRS-50X1 Features Review

    Downs bought the 1225, for substantially less than that and without the cable. The Kenwwood is better in terms of finding the proper software. Also has more channels. For your use, either is good but the Motorola is more compact and maybe a little simpler to operate. But if you do get a Motorola, it's probably best to pay a shop the $25 or so to program it, or buy it from a shop (used-radios.com for example) that will program it for you.
