Talkabout MH230R does not Receive or Transmit on channel, can just Transmit (only clicks when Recieve) when programmed 2 channels higher (i.e. all radios on 5-3, one is on 7-3)


Strange. Could it be any of the radios are from different countries? The channels are not worldwide. For instance, Canadian radios are on different frequencies than USA radios. They look identical.

Need a service manual need to modify a MR f55 radio to transmit on 161.600 mhz can you help?


Hello,
You want to be able to transmit to the Coast Station on this frequency I assume. The Coast Guard monitors channel 16 at all times. This would be the primary channel in the United States. Your radio is VHF Marine Radio and has a built in frequency range of 156.050 MHz to 163.275 MHz. There is no need for a modification. This is a duplex frequency. What that means is you will transmit on one frequency and receive on another, while on channel 20. You will not need to transmit on 161.600. Turn your radio to channel 20. When you transmit, you will transmit on 157.000. And when the Port responds to you your radio will automatically receive their signal on 161.600. So if you are trying to figure out how to communicate with the port authorities then for that frequency turn your radio to channel 20 and you will be able to communicate with them.

Regards, Tony

I jus was wondering, can the cb radio and the handheld radio transmit on the same channel? Im a security officer and im interested in purchase a cb radio so we can use it at work but i dont know if its...


CB radios and hand-held CB radios can operate on the same channel and be in contact with each other. Other hand-held radios do not operate on the same frequencies and even though they may have channel numbers the channels have different frequencies and will not operate to CB radios.

NO TRANSMIT ON ANY BAND...


the sulution to the problem is simple, you call cobra and tell them you need part# 010-133 Description TRD-16HHF-CA TRANS RD16HHF1. This part costs only $10.00 not including shipping, It's the transistor for the output stage of the amplifier and is a known problem with the radio... It's simple to replace and only takes a very few minutes.. This will fix the problem and get your radio up and running again.

No transmitting with Raymarine Ray45VHF


Hi,

Re your queries:
1. how to memorize channels?
The channels are pre-programmed that a channel number corresponds to a frequency setting. Ex. Ch16 is 156.800 . If for some reasons some channels are missing, perhaps your best course of action is to reset the unit to factory default, that way everything would be back to  normal. Master reset is performed by pressing the 16PLUS button while powering the radio. The LCD will display "CL" indicating that the memory has been cleared.
If you  want to memorize a certain channel/frequency, you can only store it as a replacement for 16PLUS assignment. Ex. Instead of Ch16 as your priority/emergency channel you want say Ch14 (156.700), you can do this by pressing the up/down key till your desired channel; press & hold the 16PLUS key for 3 seconds or until you hear the confirmation beep that your desired channel has been memorized in the memory as the new 16PLUS.

2. Why I cannot transmit?
There could be 2 possible reasons:
2.1 You are transmitting on a channel that has been assigned as receive only. Examples are the weather channels, Channels 1,2,3,  also 70,75,76, and possibly others.
2.2 Your TX module/circuitry has a problem. More often it is the finals that gets burned.

3. When i use the PTT Channel 16 is automatically set ?
The mic has an identical 16PLUS button (similar to the radio's front panel). If you pressed the PTT switch on the side and the radio switches to Ch16 (as if you pressed the 16PLUS button on the front) then you have a wiring problem from the mic to the radio. Possibly a shorted or open connection.  It is also possible that you have a break in the small PCB (in some versions) inside the microphone.

The user's manual can provide a more detailed instruction.  It is available at the RayMarine website and the link is >
http://www.raymarine.com/SubmittedFiles/Handbooks/Legacy_Handbooks/communications/RAY45MANUAL.pdf

Hope this be of some help/idea. Post back how things turns up or should you need further information.

Good luck and kind regards.

Lost channels in a galaxy 66v cb radio


as far as the transmit frequency changing while you have the mic keyed this is normal, the transmit frequency is a little different than the receive, as far as the lost channels go you need to check the galaxy website and check to see if thier is any fixes listed. if none is listed then you can send the tech's a e-mail and tell them your problem and they will advise you on what to do.
