If you're still getting loud squelch noise but do not receive on any channel, you must check the RF from the antenna to the audio stage(not included). There must be more than just one RF stage in this radio. Let me know what you find.

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.

Ok! well i deffinitally know what the problem is. You need to play with the clarifier, i think all the way to the left is a "course and fine tune" knob. This is generally for use when talking on SSB. but may affect AM if its way off.

The clarifier lets you slide on the freq. some radios will go a full channel some will only go a little or above the center of the channel. You need to play with the clarifier, you probably need to turn the course a lot, untill the audio is almost clear on the channel you want to talk on, than use the fine to tune it in so it sounds like they are sitting right next to you.

what you should do is buy a Frequency counter, you got a nice radio, so the freq. counter wouldent hurt. lets say you want to be on channel 19. you would turn the clarifiers untill i read 27.1850 That would put you right on the money

1 why would you change the finals?? Have you checked you antenna? How are your SWR's? Crappy antenna's cause a lot of problems.

Use an external meter to see what the SWR is, and see what the output is PEP. If its low, then there is something wrong. If it is High, change the mic and turn up the dynamic all the way.

Next. Have you been messing around in there?? Tryin to get more wattage? You turned VR4? If you thought you were turning it up by turning it all the way to the right, you turned it all the way down. Turn it all the way to the left.

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.

My JHP 500 Tranceiver will receive but not transmit, any Idea's


It may have been PLL instead of PPL. If so, that stands for Phase-Locked Loop, and is the circuit that the transmitter needs to generate the desired frequency to transmit on. That being the case, there's no user remedy and the unit must be serviced by a qualified radio shop.

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

Cant transmit out


Not really enough info to help you, but you MUST check the SWR of your antenna system. I've seen many cases where the antenna studs were incorrectly installed, shorting the antennas to ground. Also, make sure the Dynamike control on the CB radio is turned fully clockwise.

Cobra 19 DX IV CB Radio Gets no signal at all


my only idea is the frequency that Canadians transmit/recieve on is different than us down south (in the USA). I know Europe and the UK use a different frequency range so my guess is that Canada uses a different radio frequency range than the U.S. making you unable to communicate with fellow radio users. You may be able to search the frequency range for Canada vs. the U.S. and see if there's a difference. Hope this helps...and again, it's just a thought.
