It'll keep the repeater recording until you stop complaining. Practice a lot. Review: Low quality cable. Repeater works fine. - The repeater itself works fairly well. For a long time I thought it was broken, but it turns out the cable is just poor quality. I have a few different brands and models of radios with Kenwood style connectors, and they all need a thumb or rubber band around the radio to hold the plug firmly into the socket. I'll just have to find or build a better cable at some point. ## Features - 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 retransmits 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B014H2D2TM | | Best Sellers Rank | #2,676 in Portable FRS Two-Way Radios | | Brand | Wishring | | Built-In Media | Cable | | Color | black, white | | Compatible Devices | Baofeng, BaoJie, Kenwood, Linton, Puxing, Wouxun, Quansheng radios | | Customer Reviews | 4.0 out of 5 stars 11 Reviews | | Data Transfer Rate | 19200 bits_per_second | | Frequency Bands Supported | VHF, UHF | | Included Components | Cable | | Manufacturer | Sunkin Global Trading Company | | Mfr Part Number | SU-114915 | | Model Number | Sr 112 | | Number of Items | 1 | | Number of Packs | 1 | | Special Feature | Portable | | Special Features | Portable | | UPC | 710749699105 | | Unit Count | 1 Count | | Wireless Communication Standard | Radio Frequency | | Wireless Compability | Radio Frequency | ## Product Details - **Brand:** Wishring - **Color:** black, white - **Data Transfer Rate:** 19200 bits_per_second - **Special Feature:** Portable - **Wireless Communication Standard:** Radio Frequency ## Images ![Surecom SR-112 Cross Band Radio Simplex Repeater Controller with K Plug 46-K Cable for Kenwood PUXING WOUXUN QUANSHENG - Image 1](https://m.media-amazon.com/images/I/41IocARP1eL.jpg) ![Surecom SR-112 Cross Band Radio Simplex Repeater Controller with K Plug 46-K Cable for Kenwood PUXING WOUXUN QUANSHENG - Image 2](https://m.media-amazon.com/images/I/41Phkl2TdqL.jpg) ![Surecom SR-112 Cross Band Radio Simplex Repeater Controller with K Plug 46-K Cable for Kenwood PUXING WOUXUN QUANSHENG - Image 3](https://m.media-amazon.com/images/I/41tph3DLHWL.jpg) ![Surecom SR-112 Cross Band Radio Simplex Repeater Controller with K Plug 46-K Cable for Kenwood PUXING WOUXUN QUANSHENG - Image 4](https://m.media-amazon.com/images/I/71lWVEtXTQL.jpg) ![Surecom SR-112 Cross Band Radio Simplex Repeater Controller with K Plug 46-K Cable for Kenwood PUXING WOUXUN QUANSHENG - Image 5](https://m.media-amazon.com/images/I/41lB-IBgZVL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Don't get cut off. *by H***L on August 2, 2023* Program a CTSS code into the output frequency of your portable walkie talkie. 67 Hz will do. It'll keep the repeater recording until you stop complaining. Practice a lot. ### ⭐⭐⭐⭐ Low quality cable. Repeater works fine. *by C***S on November 21, 2025* The repeater itself works fairly well. For a long time I thought it was broken, but it turns out the cable is just poor quality. I have a few different brands and models of radios with Kenwood style connectors, and they all need a thumb or rubber band around the radio to hold the plug firmly into the socket. I'll just have to find or build a better cable at some point. ### ⭐ REVIEW UPDATE: IT IS JUNK!!! :( *by M***. on September 21, 2016* UPDATE: - After more extensive testing I had to conclude that this unit, in any and all configurations, with or without using the #1 mailbox for identification, whether it is charging or fully charged, makes no difference and keeps cutting off the transmission on its own unexpectedly without any reasons, making it completely USELESS!!! :( - Entering DTMF tones for system changes is an excruciating pain! It took dozens and dozens of trials just to put it into Sleep Mode and then back into Wake (operational) mode. - Changing the Pass-Code took approximately 70-80 trials, NO exaggeration! - With voice, I was barely able to complete a 10 second sentence, and usually got cut off within 3-4 seconds. THIS THING, AS IS, IS A PIECE OF WORTHLESS TRASH! :( =============================================== THE GOOD: - Small and ultra lightweight. - Has built-in battery. - Easy to use. - Wide range of compatibility. - Simple "poor man's repeater" solution. - Does NOT require to comply with "repeater" rules! - USB charge option. - Last message playback. - One outgoing message (for Station ID or other identification) and 2 additional voice-mailboxes. THE BAD: - Unexpectedly switches from Reception to Transmission in the middle of a talk. - DTMF codes take time to learn and figure out. SUMMARY: This tiny little thing can solve a lot of issues for many radio operators, whether it is used for simple walkie-talkies or more advanced HAM radios. You simply turn it on, connect it one of your radios, adjust the volume on that unit and then ready to go! THAT'S IT for basic operation. Of course, if you want extras, then you have them too! First of, you can and should change your passcode right away in order to avoid unauthorized access and to put the unit into SLEEP mode (stop it from transmitting) when necessary. Then of course, you can setup an outgoing message in mailbox #1, which can be your station identification (this is .... (your call-sign) and this is an automated simplex repeater system - or something). Also, if you want to leave important messages to your party, then you can use mailbox #2, and they can use mailbox #3 to reply to you without deleting each other's messages. It also has a "Repeat Last Message" function for the live repeater mode, so if you didn't quite catch the message your party said, you can play it back again. Naturally, you can activate/deactivate the unit with your radio's DTMF tone (digital dial-tone) IF your radio has it. If you're using a walkie-talkie, then this is NOT an option for you obviously. The one REALLY, and I mean, REALLY (!!!) IRRITATING thing is when this unit, just out of the blue all by itself, CUTS YOU OFF and instead of taking your transmission, it just stops and switches into sending mode, without you knowing it because there is no feedback, so the only way you know your transmission was cut off by listening back and then realizing the problem. This also affects DTMF codes, which, out of 12 trials only got through 2 times for me! I've read that others complain about the same issue, but the officials could only recommend two solutions. One; Wait till the unit fully charged up and NOT connected to the charger any more, and Two: Disable the automated station voice identification transmission from your mailbox #1. But again, that's one of the MOST important and useful feature, to have the station automatically identify itself, so you CAN hear it away and know that you're STILL within reach of your unit. But I've tested it and sorry to say that NEITHER of these ideas solve this extremely irritating problem, which makes the entire system UNRELIABLE at best! :( CONCLUSION: - If you're willing to compromise to the erroneous receive cut-off issue, then this unit is a great little simplex repeater! And the BEST part is that by law, this is NOT a repeater (!!!) and so, does NOT have to comply with the frequency limitations and restrictions of full-fledged Duplex-Repeaters and/or Cross-Band Repeaters that qualifies as a auxiliary-station with its own set of rules and technical complications (to comply with the rules). So, in the end, I give it 3 Stars for being unreliable, but still useful! :) ## Frequently Bought Together - Surecom Sr-112 Simplex Repeater Controller with Kenwood Radio Cable - Superbat UHF Male PL-259 to UHF Male PL-259 Low Loss Digital Coax UHF Jumper Cable (12" RG58) for HAM & CB Radio,Antenna Analyzer,Dummy Load,SWR Meter - Mcbazel Surecom SR-112 Cross Band Radio Simplex Repeater Controller with K Plug 46-K Cable for Kenwood PUXING WOUXUN QUANSHENG --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/73420132-surecom-sr-112-cross-band-radio-simplex-repeater-controller-k](https://www.desertcart.at/products/73420132-surecom-sr-112-cross-band-radio-simplex-repeater-controller-k) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-10-17*
