Review on Surecom SR-112 Cross Band Radio Simplex Repeater Controller with K Plug 46-K Cable for Kenwood, PUXING, WOUXUN, QUANSHENG - by Mcbazel by Sean Patel

I bought this to install a simplex repeater and so far it has worked great. I had some problems with it in the beginning, but it worked in the end. Make sure you read and understand the instructions before attempting to set it up. I initially had some issues with not repeating or recording messages. If the connected radio volume is found to be too low, it will not record or repeat. It has a great standby battery, but I haven't used it much to see how long the battery lasts during use.
