Hello janetsue, If this radio has the blue or green screen LCD face then this is a default that is built into the radio. It depends on how the radio was "converted" when it was bought new.
It will not key up on 10 or 12 because of the default. A little more info supplied would be real helpful,,,, Let me know, Mechanic

O am mode my recieve meter doesnt move but i recieve and can transmitt..wha


Not sure what you mean, but there is always atmospheric noise. You use your squelch to adjust it to where the static you hear is just silenced. You will never not hear noise on AM or SSB. It is the nature of the mode. On FM its a different story.

Can you turn the rf gain pod up for better receiving


Yes you can turn up VR pot inside to recieve max level but will cause noise to be max too. I don't rightfully remember which one does it but I'll refer you to Defcom cb radio mods for a spec sheet
or Snakedoctors cb radio mods google site. Go to these radio mods sites on Google search and type in radio model. It will tell you what Vr inside to turn up RX of RF gain. Turn up modulation and written instruction if you are handy with solder gun how to change a resistor or cap to make it more sensitive recieve. How to replace final stage and resistors to 1/2 watt size for 6 more watts output and spread coils 1/8 inch apart like a comb for 100% microphone loudness or swing output. say 3 watts to 40 watts output. More windshield wiper swing in meter makes loud voice and extends range with Power final boost. Most people prefer to keep a mobile at around 11 watts swing to 45 watts.(but on generic radio meter will show 2 to 5 watts-its not accurate just a cheap indicator you are forward swing). Even though factory says 4 watts FCC hogwash. They come tuned from Cobra with 11 watts to 14-22 watts.Cobra really peaks them babies so competition doesn't beat them out like new louder radios made by Galaxy 55. Even though law says blah blah (corporations bend it)sales pitch Galaxy very heated with Cobra on the game(rich can do what they want)Galaxy is 20 watts factory with big promise to 40 watts dual finals. So Cobra updated and said "screw it we will break the law too" Now Cobra is loud as ever and offering their own super mod versions and dual final radios with 45 to 65 watts output with ranges on SSB & USB of 1500 miles on a strong good outdoor antenna.

Purchased a midland 75 785 from u s will it work on u k channels


  • For 11 meter (CB) the standard 40 channels will be the exactly same as the "EU" set of frequencies (channels). However the "UK" 11 meter (40 channels) and the U.S.A. 40 11 meter (40channels CB) will not work together at all. This includes any actual Citizen Band radio, excluding Export 10 an 12 meter radios often labeled as "CB'S" which they are not.

  • Hope this helps.

Galaxy DX 959. SSB doesn't seem to work. The power meter needle moves in AM but not in SSB. I tried adjusting the bias between test points 7 & 9 to 50 mA via VR12, but can only get it down to 90...


on ssyou are some what familiar with working on radio's. just make sure before you pull your hair out aligning the radio that you made sure it definitely is not tx on ssb. b the.Mic gain will increase the modulation. it could just be a meter issue. confirm this by having some one on another radio on ssb the same channel listen for you. if he cannot hear you then the ssb is blown out.sounds likelike

RG 66,99,DX2517 Replace Q54 2SB754 60watt 7A with a higher power 2SB817 100 Watt 12A. Derating of this component will cool operation, provide better voltage stability,decrease wobble, allow voltage increase to 14.5 volts comfortably. (replace 10 volt caps in this section of the radio to a minimum of 16 volts before increasing supply voltage to this level)and provide faster swing rise time, Replace Q37 2SA473 to a 2SA1012-0 or ECG153 this will improve the clarity and volume of the modulation and it will also run a lot cooler.

President HR-2510 will not transmit or recieve


Hi Darrel,

Since you didn't say if you have ever used this radio successfully before, I have to assume it is "new to you" and that you have never seen it work or used one like it before. Start with a few basic settings below:

Turn Squelch to minimum.
Set RF Gain (if present) to maximum
Set Mode to AM or FM
Set volume to 1/3 up
Connect to 50 ohm dummy load.

Turn power on. Hopefully you hear static. If not, try SSB or FM. Still nothing? Try connecting to an external speaker.

Chnage back to AM or FM mode. Key mic check & for transmit indicator. If none, change mic or manually short the PTT contacts in the mic or at the radio to see if it can be made to xmit.

If no xmit - insert SWR meter between xmitter and dummy load. Try to xmit on AM or FM again while watching SWR forward power, if none indicated, xmitter is probably defective.

Replacing parts in a xmitter is not recommended. You'll need an FCC license and a fair amount of expensive test equipment to test repairs, set power levels and deviation and perform an alignment to be sure you aren't causing interference on other frequencies and bands.

You'd be better off bringing it to a radio repair shop for repairs and an alignment.
