It sounds like you are having an issue with your GP339 radio where the PTT (Push-To-Talk) switch is not transmitting when pressed. Here are a few potential solutions to try:

  1. Check the battery: Make sure that the battery is fully charged and properly installed in the radio.
  2. Check the antenna: Make sure that the antenna is properly connected and not damaged.
  3. Check the settings: Make sure that the radio is set to the correct frequency and that the PTT switch is configured correctly in the settings.
  4. Check the microphone: Make sure that the microphone is properly connected and not damaged.
  5. Check the programming: Make sure that the radio is properly programmed with the correct settings, including the correct channels and frequencies.
  6. Check for physical damage: Make sure that the radio does not have any physical damage, such as a broken switch or damaged wiring.
  7. Check that the radio is programmed for the correct channel.
  8. Check that the radio is not in "Low Power" mode, if so, switch it to "high power" mode.
If these steps do not resolve the issue, it may be necessary to contact the manufacturer or a professional radio technician for further assistance.

I have a vhf 25 W radio set . Rx is ok but no Tx .my ptt is ok then whats the problem

A lot more information is needed to get started on helping your resolve your problem. First, you have not provided any information about your radio (make and model at least). You said that your PTT is ok, but no transmit. The PTT is just a switch to switch between RX and TX.

Have you tested the output with a watt meter into a dummy load? What other tests have you performed, when did the problem start, and what was being done prior to the start of the problem.

Have you talked to any local ham radio operators about this problem and asked for their assistance?

I have a Vintage kinematix reverb with 5 wires red,yellow,white,brown and black how I hook it up what are the wire? it also has a delay tuning knob

usualy you have a transmit recieve switch
like this
.....common
RX <<-- >TX ptt

so three wires
the ptt button common in a cb with 4 pins is also ground
should be
black screen and i think brown
but you need to meter out the ptt common and RX TX
for rx audio switched radios then one pin is RX one pin is TX one pin is common or ground for the PTT and also ground for the screening copper braids and also ground for the transmit audio
so you have 5 wires
3 will be PTT 1 will be audio and one audio ground
usually white or yellow
so i think black and yellow or black and white
black being ground

just look up the schematic or service manual for your CB
and check out the 4 pin plug config
there is only two usual ones
cybernet or uniden so.. easy stuff
look for like cybernet cb 4 pin wireup in google or similar
remember just meter out using the beep test range on a cheep multimeter too see which three are the PTT
so the common of the ptt needs connected to the copper screening and also to the black wire all to the ground pin on the 4 pin plug
you can short from the ground pin on the cb side to its TX pin and the set will enter tx mode
same with rx audio enable {if uses most cb post 1984 dont use RX audio hard switching}
so just three pins to worry about

Cx80 stuck in rx mode , power cycled, swapped batteries, changed channels, will only swtich to tx when ptt button pressed, otherwise always in rx mode, other radio from package works fine

But thats how a walkie talkie works, it stays in Receive Rx mode UNTIL you press the PTT button,, then it Transmits Tx, and when released it goes back to Rx, receive?

Kenwood ts-450s - cannot tune and no ptt

This is usually due to a stuck or shorted ptt line. I have repaired a couple of these and it was the same component each time. The packet TX transistor Q65 shorted causing the radio to power up in TX inhibit mode. Transistor Q65 is located on the underside of the IF board under the ACC 2 connector. This switching transistor is used only for tx (pin 9 of acc 2) and no other circuits depend on it. It can be removed completely if you don't mind not having ptt on acc 2.
This seems to be a common problem lately, I hope this helps you.

Squelch when keying ptt

I would check my ptt wiring making sure the button is set so that when you push it it switches you from RX to TX. If you have a wiring diagram that would be helpful if not are you able to get one? In any event make sure the wires are not misconnected.
