Hello jeff,
Welcome to FixYa.
My name is John, and I will be assisting you with your issue.
Some radio,s will do that from time to time. Try to thump it real
lightly, but do not break it. It will sometimes come unstuck, some others have to be replaced.
It is nothing to worry about, it does not hurt your unit. Try that and if it does not work, and if you want to replace it, let me know. We are always here to help you. Your Comments and
Testimony's are always welcomed here, and thanks for choosing FixYa today and in the future.

John

On my connex 4600 turbo cb radio i keyed the mic up to say something and the meter light and the channel number got dim and sort of flickered and distored, also the needle in the meter didnt swing at all...


I would think it was most likely a minor short in your mic, maybe dirt or moisture. If the short was in the back of the jack, it would most likely do it all the time. Same thing for your coax, if it was pinched in the door, I would think you would have reception/feedback issues even without keying the mic....the same antenna/coax is used for send and recieve.

IF it does it again, try switching in another mic and see if it goes away.

Hope this is helpful.

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.

My ANT light comes on when ever i push the mic button but my SWR isnt that high


The meter will be more accurate and an external meter will be even better. If they show good disregard the ant light it is adjustable. It may have been set to sensitive from factory. These erroneous SWR reading can be the side effects of a PEAK & TUNE if the coils have been spread but that should also show on meter.
SWR meter calibrations
  • Switch (S/RF SWR CAL) to the CAL position.
  • Push and hold mic button
  • While holding mic button adjust the SWR CAL knob so the meter needle swings to the CAL mark on the meter
  • While still holding down the mic button, set the (S/RF SWR CAL) switch to the SWR position, to read the SWR reading. Note: When switched to SWR position the meter needle should ideally be as far to the left as possible. Anything over 3 is not acceptable.

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.

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.
