With V9 repeater hot selling in many countries and markets, we received a lot of questions from our customers. V9 repeater is easy enough to use and install, compared with other repeater base stations. There are some after-sales issues that many customers are concerned about. Let’s take a look at these issues and resolve them today.
FAQ of V9 Repeater
Q1: Can V9 Mobile repeaters be connected so that multiple devices can work together?
A: V9 is a portable analog repeater so it can’t work with each other by a network. If you need to connect many repeaters, we suggest you use V9D digital repeater or another base repeaters with higher output power.
Q2: My V9 transmitter is noisy. Why?
A: First, please check if the antenna matches the V9 frequency band? Please note that V9 distinguishes between UHF and VHF. Then, is the antenna and V9 repeater in good contact? Second, please check if there is other signal interference near by? Third, please adjust the squelch level to an intermediate value. Fourth, please try to use another environment. Fifth, if you are using the GMRS frequency band, please check whether the wide and narrow bands match. The factory setting of V9 GMRS is the narrow-band.
Q3: What frequency range can V9 support?
A: V9 repeater can be customized 136-174Mhz or 400-470Mhz.
Q4: Does V9 have a dual standby function?
A: The V9 repeater does not have the dual standby function. The repeater currently does not have the multi-frequency forwarding and multi-standby functions.
Q5: What are the power requirements for V9?
A: The output voltage of V9 repeater is DC 12V, the current is 5A, and the voltage can be used in DC12-24V.
Q6: Does the V9 repeater come with a battery?
A: The V9 original repeater doesn’t include the battery.
Q7: What is the offset support of V9 repeater?
A: V9 repeater supports 5-12Mhz offset.
Q8: What is the standby current of V9 repeater?
A: The standby current of V9 repeater is 90mA.
Q9: Can I customize low frequency for TX, and high frequency for RX?
A: For the repeater, it is best to set high TX frequency and Low RX frequency. It is also possible to set low frequency for TX, and high frequency for RX, but the output power will be reduced accordingly.
Q10: Can I only customize the frequency of the duplexer to change the frequency of V9
A: Yes, it is ok, you can use new duplexer to change the frequency of V9.
Q11: What is the connector type of V9 repeater?
A: V9 repeater is UHF/SL16/PL259(F/K Female).
Q12: How many DCS and CTCSS codes does the V9 repeater have?
A: The V9 repeater has 50DCS and 210 CTCSS codes.
Q13: Do you have a Power Amplifier for V9, which can extend the power of V9?
A: Sorry, we don’t have a power amplifier for V9 repeater.
Q14: Can V9 work without a duplexer?
A: The V9 repeater can indeed remove the duplexer and use dual antennas for transmission and reception. But V9 is a mini turntable, and the built-in duplexer is used to install it most simply. If you don’t use a duplexer, use 2 antennas. And the height of the antenna must have a 5-meter drop. We don’t recommend you to do this. But if you are a ham, and want to explore, you can have a try.
Q15: Can two encrypted radios communicate with each other through V9 repeater?
A: Two encrypted radios can communicate with each other through V9 repeater, the sound quality will be reduced a bit.
Q16: What do the two blank lines mean in Embedded Message in V9 programming software?
A: This is for remarks, such as writing the date of manufacture.
Q17: How far can the V9 repeater increase the call distance?
A: The distance depends on the height of the antenna and the environment in which it is used.
As we tested, we used two 10w cameras to test. The relay was in the middle. The diameter of the two cameras was 16 kilometers. The distance between the camera and the relay was 8 kilometers. At that time, the height of our antenna was 27 meters.
