CB is in transmit mode with no mic connected


Got a short either at the mic socket or the keying circuit--try first to disconnect leads at the socket one at a time.

Got a connex 3300HP has a ranger board and chipset won't modulate recieves fine keys up relay clicks needle doesn't move no voice either cant find schematics


You may have a dead meter.
Modulation is audio's affect on swing wattage or pep. Notice that needle moving more with your voice.
Dead key or carrier wattage is without your voice enhancing the power only with mic keyed.
I can only assume that the chipset you are referring to is an ic chip audio or pll which must be working if you are receiving audio.
Check your mic cord................ transmit and modulation and even your receive volume can be affected by the cord/mic plug solder joints or broken wires here.

I have the new galaxy 959 and i purchased new coax and k40 helicoil 20,000 watt antenna but my swrs are too high and my radio is acting like its keyed up or should i say the needle swings pn it very own as...


Your radio shouldn't be keying on it's own no matter where your SWR's are at. I would start simple by checking your mic plug, then inside the mic for cold solder joints, or shorts. Do this after you borrow a compatible mic and try the key-up. Just don't key very long before you get your standing wave ratio in check. I'm talking like 1 second.

How do i calibrate an Aries swr 420 meter for a cb radio


To calibrate the meter set the switch to FWD/CAL/REF and key the microphone without speaking into it. then turn the control until the needle is on CAL. Unkey the mic, set the switch to SWR and then key the mic to read the SWR.

Thanks,

Dont know how to use the swr meter on my radio


With radio turned on

1. Switch the first switch (S/RF SWR CAL) to CAL setting
2. Key mic up &
3. Turn SWR CAL knob while still keying mic until the needle is on the red CAL arrow at the far end of the meter scale. Unkey mic.
4. Switch the first switch back to SWR setting.
5. Key mic up again and record SWR reading and adjust as needed.
6. When done adjusting put switch back in the S/RF setting for normal operation.

Do not flip the switch with the mic keyed up.

Radio stuck in transmit meter needle is slammed all the way to the right as soon as you turn unit on


Have you recently changed mics ? if so it is wired wrong, if not I would check for a shorted wire in the mic connector or the mic itself.
