SR-112 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. 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, but 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. Major Features - 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 -19.2 KHz sample rate for excellent voice clarity -Operates from 14500 3.7V Li-ion or external 5-24 V DC supply -build-in rechargeable Lithium-ion battery support 72 hours long life operation -User to change the DTMF remote control password by radio -User set the Repeater Operates On/Off by DTMF -Audio output adjustable in hardware and by remote command -Audio in Level display -Auto Battery level display (20%~100%) -Provides audio Input level display ( for adj. best sound ) -Provides signal roger beep setting -DTMF signal display -Works with most popular CB,FRS, PMR, Amateur radios, Mobile Radio (optional of Cable) -1 year warranty on complete unit, 5 years on flash memory Manual Wholesale Quotation Shopping If you have related videos, please share with us, please contact us

CB RADIO Citizens band radio (also known as CB radio), used in many countries, is a land mobile radio system, a system allowing short-distance person-to-person bidirectional voice communication between individuals, using two way radios operating on 40 channels near 27 MHz (11 m) in the high frequency (a.k.a. shortwave) band. Citizens band is distinct from other personal radio service allocations such as FRS, GMRS, MURS, UHF CB and the Amateur Radio Service ("ham" radio). In many countries, CB operation does not require a license, and (unlike amateur radio) it may be used for business or personal communications.

SW-111 Designed to indicate the condition of any 50 ohm antenna and coax for cbs, 10 watts and 100 watts switches, forward and reverse switches, radio and antenna connectors on the back function analog meter compact antenna and coax test device.　 Features: 3 function analog meter Indicates the condition of a 50 ohm antenna and coax used for CB operation Tests for SWR or relative power 10 watt and 100 watt switches Forward and reverse switches Manual Wholesale Quotation Shopping Brand SURECOM Model SW-111 SWR :1:1 to 3:1 RF Power : 0-10WATT / 0-100WATT Frequency : 27-30MHz (CB radio Band) Impedance : 52 ohms Item Weight 120g Product Dimensions 84(W)X 59(H) X52(D)mm Package include : 1x SURECOM SW-111 SWR /POWER METER 1x English Manual INSTALLATION: 1 Turn off the transmitter and disconnect the coaxial cable from the antenna at the output. 2 Connect the connector “TRANS” to the transmitter output and “ANT” to the antenna connector. 3 Set the slide switch to “SWR” and “FWD”. Turn "SET & FS ADJ" counterclockwise almost at least 4 Turn on the transmitter, turn “SET & FS ADJ” to full scale, “SET” position on the meter. 5 Then set the FWD / REF slider to “REF” and read the meter scale. The meter will give the SWR reading directly. 6 MEASURE SWR: A ratio of 1:1 is the ideal combination. Adjustments to the antenna system should be made so that the SWR is as low as possible. A SWR of 1.5 is considered satisfactory, taking into account line losses and slight mismatch. The operator is directed to numerous articles in radio magazines and books dealing with various methods of matching different types of antennas. 7 The power required for the operation of the SWR bridge depends on the frequency; about 5 watts 27 MHz or above. 8 MEASURE POWER FWD: Set the slide switch (SWR, PWR) to the POWER position and set the range slide switch (FWD, REF) to 10 watts or 100 watts position, whichever is appropriate. 9 When the TX of the transmitter is turned on, the needle of the meter deviates. Read the amount of deflection on the upper scale. If the range switch was set to the 100 watt range, the value is multiplied by 10. 10 For an accurate power reading, the SW111 should be used on circuits with SWR values up to 1.5. The meter will accurately decrease if the SWR value exceeds 1.5 11 Always turn off the meter when removing it from the circuit. NEVER disconnect the “ANT” connector during transmission. The voltage generated can damage the transmitter. If you have related videos, please share with us, please contact us

SE-01 The SE-01 PTT button activates computer software that communicates to the phone or tablet and activates the PTT of the PoC App. directly. The SE-01 PTT works just like a normal PTT, push to talk and release to listen. There is no battery to charge and the SE-01 does not add any battery drain to your phone or tablet (the SE-01 has a small disposable battery you can easily change, but it will last from 1 to 2 years so it is very inexpensive to operate.) Using the SE-01 is super easy! Select 'External PTT' in your PoC App (not every PTT App supports external PTT, so check first.) Plug in the SE-01, and simply press the PTT to start talking. There is nothing to pair, nothing to charge. Couldn't be much easier Features: POC Audio Accessory Solution For Zello App on iOS and Android. Ear for hygeine & all-day comfort. Noise Reduction Knowles Microphone. Front Facing PTT Button. Designed & Engineered in the HONGKONG This is our NEWEST invention for our customers wanting to use PTT apps on cell phones and tablets. Most cell phones and tablets do not support any kind of external Push-to-Talk (PTT) function on their accessory plugs,so users have either had to use the device screen or Bluetooth to make the PTT work. Sometimes it's not easy to push a PTT on the device screen, and Bluetooth can be inconvenient since it needs pairing, battery charging, etc. The SE-01 PTT solves this problem by having the computer software inside! (like phone calling, music playing, photo taking, etc.) Manual Wholesale Quotation Shopping Package Include: 1x SE-01 PTT Controller with Mic 1x 3.5mm MONO Earpiece Set-up wired accessories for Zello Android Depending on the Android device, you may need to disable Google Play Music under applications to prevent the headset hook from bringing up music. If you're using one of the Zello recommended accessories that function as a push-to-talk device, log into your management console and go to Settings > Android > "Enable Use specialized wired PTT speaker-mic or headset" and save. 1. Connect the accessory to your mobile device 2. Open Zello "Options" > "Push-to-talk button" 3. Select "Add Button" on the top right. You'll get a prompt asking you to press the desired button and it will be added as a "Headset hook". 4. Make sure the button is set to "Toggle mode" and that "Handle headset button when in the background" is enabled. Even though it's set to toggle mode, the accessory will work as a push-to-talk mode if it's listed as push-to-talk from the website. If you're using a device not listed, it will most likely only work as Toggle mode. iPhone/iPod/iPad Although Zello does have the option to map a headset hook from an Apple headset, it is not often reliable. Zello does not have the control to maintain the headset hook for PTT control, so the headset button will may sometimes trigger music. To prevent this from happening, make sure you don't have a music app in the background while using Zello. Connect your headset to your iPhone and then follow these steps: 1. Set push to talk button "Action" to "Toggle". (Zello menu>Options>Push To Talk button>Action>Toggle). 2. Make sure you have enabled "Headset/remote control" enabled. 3. Go to Audio settings and make sure you have "Mix with other audio" turned Off (Zello menu > Options > Audio > Mix with other audio > Off ).
