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

Why does my mr hh300 display UL on the screen. It won't do anything but display UL. The batteries show fully charged. I worked a couple of months ago. Unplugged due to getting new flooring and


UL means "Out of Lock". The synthesizer is having a problem. This can have many causes. Did someone try to modify it for expanded channels, that is mostly what causes this. If the radio is factory original it could be the VCO, the PLL chip or the reference oscillator that is causing the problem. The reference oscillator is the easiest to check; listen on a shortwave receiver if you can hear a carrier coming from the CB at 10.240 MHz (hold the receiver antenna real close to the CB)

Do i need ariel for cobra MR F55 EU radio


? I assume you are asking if you need an ariel antenna for this radio in order to receive and transmit? if that is the case then yes you do, Any radio requires a matched antenna in order to transmit, if you were to transmit without an antenna, most of the RF energy will transfer back into the radio and over heat "burn out" the output transistors. always make sure to have a proper antenna connected before transmitting on any radio.

Is there a way to change the frequency of a specific channel?


FRS & GMRS frequencies have been preset by the governing bodies where these radios are licensed for use. They consist of Ch 1 - 14 for FRS or Family Radios Service (the new "CB" radio) and Ch 15 - 22 for GMRS or General Mobile radio Service. GMRS frequencies may be repeated 5 Mhz higher - the repeater input of channel 22 (462.750 Mhz) may be heard if close to the transmitter on Ch 22, but if a repeater has been set up to repeat signals in range on Ch 22, they would also be heard on 467.750 Mhz. The repeater will likely have one or more of the following: a high vantage point such as a hill or mountain top, may increased output power of up to 50 watts, or have an antenna with gain properties. Any one or combination of any of these benefits, will result in a significantly increased area of coverage.

FRS Frequencies Channel Frequency in MHz 1 462.5625 2 462.5875 3 462.6125 4 462.6375 5 462.6625 6 462.6875 7 462.7125 8 467.5625 9 467.5875 10 467.6125 11 467.6375 12 467.6625 13 467.6875 14 467.7125 15 462.550 16 462.575 17 462.600 18 462.625 19 462.650 20* 462.675* 21 462.700 22 462.725

It is important to note that only Ch 1 - 14 may be used without a license. Transmitting on any of the GMRS frequencies (Ch 15 - 22) shown in red in the chart above, requires an FCC license if used in the U.S.A. Other countries may or may not have laws for licensing the use of any or all these frequencies, so check before transmitting. Modifying an FRS / GMRS radio is a violation of FCC rules and if caught; can result in fines, prison or both.

If you'd like to be able to tune actual frequencies - and not be limited to specific channels, you ought to look into amateur ("ham") radio. While not in the FRS or GMRS bands, there are literally hundreds of thousands of frequencies to use once licensed. The ARRL (American Radio Relay League) has a great deal of info about ham radio.

I hope this helps & good luck! Please rate my reply - thanks!

PPT works in the lower bands (under 148 Mhz) but not 156 range


Your radio has not been modified to transmit outside of the amateur bands.

Hi dstrand, sorry you are having a problem. I will need some more info if you can. Is this radio in a base situation or mobile? Have you had any work don recently? Have you changed anything on the system? (Microphone, antenna, coax, etc)

Haave you checked your swr recently/ If yes, did you use a seperate meter or did you use one built in the radio?

Hope to hear from you soon.

Hi,

A Kenwood TM-271A is an amateur radio and therefore restricted to transmit only from 144 - 148 MHz but can receive from 136 to 174.

The TX restriction is done with a resistor (R119) which inhibits transmission outside of the 144-148 band. It is located very near a large IC (IC252).

Depending on your country's radio communications policies and/or your radio license privileges, simply removing R119 would allow transmission outside of the 144-148 MHz.

Hope this be of some help/idea. Post back should yuo need additional information.

Good luck and kind regards.
