BAOFENG SAYS THAT WILL WORK. For how long, that is a question that all of us want to know. Thinking quality and dureablity by the price, most of us have reservations that radios that cost so little will hold up. I have yaesus, kenwoods, and Baofengs. I have had no problems with the Baofengs, they have held up, easy to program and inexpensive compared to other radios.. If thje "experiment fails, the componets will be useable again. I don't see a controller, something that id's and switchs the radios from transmit to receive. Baofeng has those starting at $24.00. I am not sure they have an id'er. The radios should hold up though the transmit radio will be going for longer periods of time as compared to an individual using the radio. If you are going with a vertical antenna separation, you don't needf a cavity, but a single antenna, you will need a cavity. I would think $300 or higher for a set of cavities. Then you will have coax. Todays prices an investiment in copper. I expect a Baofengaccountant will some day run to the head office and say, "we are missing a decimal place, the radio should cost this much"..
