- In this episode, we are going to ramble about why in the world did I buy this SureCom SR-112 Simplex Repeater (see more here: radiotech.diy3dtech.com/sureco... )! DId I lose my mind or was this a good buy, well I am going to share to share with what I was thinking!
Description & Specs:
The SR-112 is a multi-function voice recorder device that connects to virtually any handheld, base, or mobile radio. It features exceptional voice recording quality and higher capacity than any other comparable device on the market.
The SR-112 s voice mail function operates like a telephone answering machine, allowing users to record messages for later retrieval. Up to 3 incoming messages can be recorded, total recording message up to 180sec
A simplex repeater records incoming transmissions and re-transmits them on the same frequency. This has the effect of doubling the time required to transmit a message, while a traditional repeater typically costs thousands of dollars and might be semi-portable at best.
A simplex repeater can be set up with a single handheld radio and operated from batteries. This makes it perfect for disaster response, home or campground use, and any place where radio range needs to be extended but the cost and complexity of a traditional repeater can’t be justified.Auto message send system 15/30/45 minutes setting
3 of message box for record - Auto Message send out at 15/30/45mins -Up to 180 seconds total recording time -DTMF remote control for all functions

It's not only useful for on-frequency range testing, I've used it to test harmonic range testing. I walk 50-100 yards away, transmit on 145.600 on one radio and listen to 291.2 on another radio (the harmonic). Lo and behold, the Quansheng UV-K5 (which is hooked up to the Surecom) sends my harmonic loud and clear up to about 100 yards, with no obstructions other than a fence. So the UV-K5 is dirty, but not so dirty that I'd avoid using it.
cant you make it a duplex repeater by making the radio do tdr?
What is the different using this simplex repeater vs a duplex repeater box where u need 2 radios. Is there a different on performance
Is there an adapter for rj45 so i can use it with a base station
Will it work while charging? Does it work with FRMS radios? What is a good roof mount antenna for the repeater?
Very interesting piece of technology 👍
Great video , can it be used on gmrs midland mxt 115 mobile
hi, a question, how many kilometers of gain did you gain with the surecom?
Great concept for “self-testing” range & coverage tests.
They should build them right into the radios I heard the UV5R can be programmed to send SR112 remote codes. Will try it, next.
Good repiter
