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

Set the radio transceiver to transmit and read the scale orresponding to the Power range selected (10W, or 100W) VSWR MEASUREMENT Step 1 1. Set the Blue botton switch to the ‘SWR set’ position.Set the Red switch to the ‘SET SWR’ position. 2. Set the radio transceiver to transmit mode. 3. Slowly turn the CAL Control Knob clockwise until the meter point is at the ‘ CAL ’ position. This should be full scale. Step 2 Set the Red botton switch to the ‘SWR’ position while transmitting. The meter will now indicate the SWR ratio. CAUTION 1. Since the meter movement is very sensitive, avoid excessive vibration or mechanical shock to the unit. 2. The absolute maximumpower that should be applied to the meter is 100W. Also observe maximumpower inputs of 10W when unsing the lower ranges. 3.

SS-11 The SS-11 Field Strength Meter is ideal for reading relative field strength from your antenna. It is a compact unit that fits in the palm of your hand and can be taken anywhere. The best part of using it is that you now can tell if your antenna is radiating or not by simply holding the unit near your antenna and adjusting the sensitivity. Also, by taking measurements, you can find out relatively how strong your antenna field is. Operation The SS-11 Field Strength Meter is very simple to use. It requires no power because your antenna field provides the power necessary to run the meter. Simply raise the single whip antenna on your unit, stand several feet away, and adjust the sensitivity knob on the front, it’s that easy. You want to ensure that the whip antenna is parallel with the polarity of the antenna you are reading. Now you can read the relative field strength of your antenna.

Small size, easy to carry, size: 75 x 100 x 64mm (excluding the raised antenna part) Instructions for use: Before use, please rotate the "amplitude adjustment" to the left most end. The length of the antenna to be pulled depends on the frequency of the test. It is better to have 1/4 wave as much as possible. The handheld walkie-talkie is about one meter away from the field strength meter. Don't be too close! In order to avoid the signal is too strong to burn the field strength meter! Then press the walkie-talkie PTT button to make the walkie-talkie enter the launch state. At this time, the pointer of the field strength meter should have a signal indication. The stronger the signal, the greater the indication! Amplitude adjustment: If the field strength indicator indicates that the maximum range is exceeded, the "amplitude adjustment" can be adjusted to let the pointer indicate the appropriate position. Method for testing the maximum gain point of an antenna 1. In order to change the frequency conveniently and quickly, you should use the keyboard to set the frequency walkie-talkie manually. 2. Link the walkie-talkie and antenna feeders, place the field strength meter near the antenna (depending on the environment), place it within the vertical radiation angle of the antenna as much as possible, and the antenna planning method is best. 3. Set the frequency of the walkie-talkie, press the launch button, observe the meter reading, and register the meter reading. Then set the walkie-talkie to other frequency points, let the walkie-talkie enter the launch state again, observe the meter reading and then compare the readings of each frequency point! You can know the best frequency/segment of the antenna under test! A typical field-strength meter is shown in Figure 1. This is a simple passive (unpowered) circuit in which radio frequency energy is intercepted by the antenna, rectified to DC, and then used to directly drive the meter. The maximum sensitivity of this circuit is based primarily on several factors: The gain of the antenna: How much of the signal is actually intercepted. The sensitivity of the meter movement being used. The nature of the diodes being used. If you have related videos, please share with us, please contact us
