Question about Two-Way Radios

1 Answer

VHF Radios I am wondering whether you can use 2 VHF radios through a single antenna. If you do... If one is transmitting from the Bridge, can the one in the Crew Mess hear both sides of the transmission? We have limited space on the mast so this is the reason for sharing antennas. Any advice gratefully accepted Thanks Richard

Hi,

Technically no. The reason is the receiver end would be overloaded with the signal from whichever is transmitting specially if on the same frequency. This could only be done if the frequencies of the two radios are largely apart and a duplexer/cavity filter is used. An alternative is to have a small local repeater, a single common antenna for both receive and transmit and a row of cavity filters. A low power portable anywhere in the vessel would be electronically repeated by the repeater to be received by any low power portable again anywhere in the vessel.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Check your antennas, use the standard antenna for best range. Also check your programming to be certain you are programmed to match one another identically, and the radio is set to high power. Check your batteries to make certain they are not bad or low. And lastly, hold your radio upright, perpendicular to the ground when transmitting for best range.

I have 4 vertex VH-160 radios, two of them have stopped transmitting, all have been dowlaoded witht he same frequencies. Batteries are good. Whe transmit buton is pushed, the is one beep then nothing. ...


The VX 160's may have bad oscillators. It is not user repairable. The simple thing to check are the antennas. Vertex radios are very susceptible to broken antennas and will not transmit. This is true of Uhf and Vhf. Replace one and try it on all the radios. Never transmit without a antenna. It can cause the PA in the radios to fail.

Looking for a 21" antenna for a Motorola SP10


There are custom made antennas for portables. But the better solution is by eradiostore, use a mag mount.1) custom portable antenna, expensive.2) Motorola adaptor to BNC to longer antenna (portable, car type or base station).
3) NO power increase, not only are those frequencies designed for low power the board inside the radio cannot handle the heat and is not changeable or adjustable.

Vhf 340 walkie-talkie radio you cannot transmit but you can receive effectively. I open the radio but no sign of any burn.I try the radio in all the channels is the same response. thanks. we use them in...


You may have a bad antenna. What happens is a lot of guys carry their radios around by the antenna, inside the connection to the antenna is weak and can crack at the solder joint, thus opening up the antenna circuit and prevent you from transmitting any power out. Our Motorola hand helds have this problem, they are weak at the antenna connector and guys swing them around by the antenna end up breaking them.
Your next problem is that if the radios have been used often enough with a faulty antenna circuit, your final amplifiers are probably toast from transmitting into an open antenna circuit, causing all the power to be reflected back into the radio and burning out the final amplifiers

Looking to build a two way radio system.


You will have to have a vehiclular repeater that is in another band than the mobile so if your portable hand held radios are on UHF then I would advise a VHF high band repeater set up.
It will have to be a cross band setup meaning it will recieve UHF and transmit on VHF and also the opposite direction.
It will have to be programmed with CTCSS or PL of some kind to avoid interference and don't forget it will need to be FCC licensed for those frequencies if it is in the Business band.
Some mobile radios can be wired up through a mini controller and run that way if it is compatible.

VHF transmit power


Hi, It is not typical but neither is there a problem with the radio. Transmit Power output is loosely dependent on the: 1. Frequency or channel you are transmitting. Normally, Marine Band VHF are calibrated for max (25 in your radio) at Ch16 or 156.800Mhz; 2. If the SWR of the antenna is not a flat 1.0, power tends to go down; 3. After some time, the TX side of the radio needs to be re-calibrated; 4. Power Supply - some radios will push max output only when powered with 13.8 and tends to go down when used with 12 volts. Hope this be of some help/idea. Post back should you need additional information. Good luck and kind regards.
