Galaxy DX 55HP stopped transmitting, but will receive. When the mic is keyed the power meter goes past max and wont transmit. Tried different mics and no difference


connect to a meter. if there is rf power on a watt meter at full wattage. then the am regulator transistor is bad. less than $5 part.

Tommy, I know why you like the radio, but I must warn you that it isn't type accepted for the amateur band. (it would be the same thing as using an amateur radio for the fire department or sheriff for emergency uses.) I have looked for the mods to change it into a 10-meter radio, and they are not to be found. My suggestion to you is to look in a recent issue of QST about building a Bluetooth (c) transceiver for your regular 10-meter radio. I had to do the same thing for my HF rig which happens to be a Yaesu FT-857D. Fire me an e-mail if you want the schematics for the box. 73 and good luck!

FT1000MP dead on 10/12 meters


Sounds like band (which encompassed CB) is locked out since transmitting on this frequency would be illegal.

I can only hear the others. When I talk they can't hear and my red anntenna keeps coming on when I push button to talk.


Assuming the antenna is mounted and grounded correctly,when you try to transmit/talk does your meter needle move to the right with your voice,if it doesn't make sure meter knob is set to receive/transmit or mod[modulate] does it move to right now,if not make sure the mic gain knob is turned up or if it is a power mic,is it turned up&have a fresh battery.The antenna light could mean high swr readings which you will have to adjust by tuning the antenna with the radio meter or external meter,you can search swr adjustment on your computer if unfamiliar..some antenna warning lights are factory set too sensitive but most times are telling you there is a problem.If all is set&tuned properly and you still can't get a local signal to respond, your radios transmit finals could be blown,which you'll need a qualified radio tech to determine..Good luck& 73's

No modulation when transmitting


No modulation could be a problem with your mic or the factory setting inside the radio. Radios are set at about 50 to 80% modulation from the factory. This is adjustable in most radios. Search mod adjustment on XXX radio and you should get info as to where the mod adjustment is located inside your radio. Turning it all the way up will not hurt it but it could cause some distortion if turned too high. Up is turning it counter clockwise.
Modulation is not shown on all built in "S" meters, just power. There are bench meters which show both power and modulation available for about $50 and up.

I have a cobra 25 ltd and when i key the mic the gauge of the db barley goes up. is something wrong ? also the gauge says its measuring tx power what does that actually mean/ do


TX means transmit. There are 3 settings for the meter. The top one is to measure your TX/RX that's transmit and receive. CAL is to calibrate the meter to check your SWR.

Reasons your needle may not be moving much when you key while on TX/RX. The dynamic is probably all the way down. That is your mic gain. If you turn that up when you talk the needle will swing more. If the radio is stock and not modded, you can turn this all the way up and leave it.

Also there could be something wrong with the mic. If people can hear you then its not the mic.

If people can hear you fine when you transmit, it may just be a bad meter. Not a big problem, you will just need an external meter to make sure you swr is not high.this is important because if it is over 1.5 you run the risk of blowing the final transistor.

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.
