It's not programmed right. You can probably find more intelligible programming instructions on Google. Their manuals are not great.

SOURCE: Some bands OK some not. No transmit, no readout on some.

its the problem of the frequency range its getting blocked  at particular location.these can be solved by two options 1)first try changing the location of the unit from one corner to another corner.that should help to catch the frequency again if its getting blocked at particular location.this happens many times.but if changing the locan does not make any difference.then  2) get checked that the antenna of the unit is not catching the required frequency for the unit.so change the antenna also connect this external antenna  as mentioned 50 ω (it comes wioth SMA Connector) that helps in catchinf the frequency. you will get this at radio shack website. this will help. ----------------------------- also in the unit there is a component which controls the frequency called microprocessor if that goes weak the unit slowly slowly stops receving the accurate signals and only the noise comes.so the micro processor in located internally in the left side.its a green and black colour mini chip circuit board.many times opening the unit and removing and cleaning the microprocessor and refitting it solves the problem but this is 50 --- 50 chance. this all has to be checked what mentioned. thank you for using fixya.

Baofeng UV5RA WILL NOT TRANSMIT


First, it's illegal to use that radio in the FRS bands. Also many of the Baofeng radios have very "dirty" output (spurs, frequency drift, bad modulation, etc). Your best bet is probably to buy another radio. With these radios about 3 of 10 I've tested have been bad.

Baofen UV5 RA wont transmit


Baofeng manuals are notoriously hard to read/interpret. Check on Google. Several people have created better instructions.

Why can't i listen to aircraft pilots & tower on my Uniden bearcat BC60XLT-1? Our airband frequency here is 108-137 mhz.


Your scanner does not receive frequencies between 54 and 137 MHz, and there's nothing you can do to enable reception in that block. Your only option is to purchase a scanner with air band coverage. Here are the reception ranges of the BC-60XLT-1:

29.0-29.7 MHz 10 Meter Amateur Band
29.7-50 MHz VHF Low Band
50-54 MHz 6 Meter Amateur Band
137-144 MHz Military Land Mobile
144-148 MHz 2 Meter Amateur Band
148-174 MHz VHF High Band
Above bands in 5 kHz steps
406-420 MHz Federal Government
420-450 MHz 70 cm Amateur Band
450-470 MHz UHF Standard Band
470-512 MHz UHF "T" Band
Above bands in 12.5 kHz steps

How do i get expanded freqs on my ft1802 yaesu tranceiver


The FT-1802 is a 50 watt 2 meter FM transceiver. It can transmit anywhere between 144 - 148 Mhz (the FM portion) of the 2 meter ham band. It can receive anywhere between 136 - 174 Mhz without any modifications. There is a modification to enable transmit "out of band" below:

http://www.ham.dmz.ro/yaesu/ft-1802-extended-transmit-modification.php

There are few details about the results of this mod - typically these provide for transmitting on frequencies outside (above, below or both) of the 2 meter ham band. Transmitting outside of the ham band without a proper license for the frequencies in the U.S. is a violation of FCC rules.

Gtl dx will not transmit below 26.955


First off, the 200 GTL DX is a 10 meter radio. Running it on 11 meters (CB) is illegal, as it is not FCC type accepted. If you go below 26.965 mhz, you are outside of the 11 meter band, and operating illegally.12 meters does not start until 24.930, so ultimately, the freq's between 24.930 and 26.965 mhz are restricted even to a licensed amateur radio operator.

Commercial radio model


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.
