The Audiovox model has a lower failure rate, larger talk button, and a built in weather band radio. Neither are currently in production.== Related ==For a list of channels and frequencies you can visit our [[FRS/GMRS]] page, keeping in mind the Memorex MK1800 is FRS only. You can use the MK1800 to communicate with bubble pack FRS radios such as the [[Cobra MicroTALK PR245 2-Way Radio]]. They are compatible and the MK1800 could serve as a base station to communicate with these HT units.There are other FRS intercoms that were on the market.
