Has no transmit ? i have a galaxy 73v - Galaxy Radios DX-73V 40-Channels Base CB Radio

The Galaxy 73V is a CB radio that has a microphone with a four-pin connector. Here are the steps to check the microphone wiring:

1. Check the microphone cable: Make sure the cable is not damaged or broken. If the cable is damaged, replace it with a new one.
2. Check the microphone pins: Check if the pins on the microphone connector are clean and straight. If they are dirty or bent, clean them or straighten them out.
3. Check the microphone wiring: Use a multimeter to check the continuity of the microphone wiring. To do this, set the multimeter to the continuity mode and touch the probes to each of the four pins on the microphone connector. You should hear a beep sound indicating that there is continuity.
4. Check the wiring connections inside the radio: Open up the radio and check if the microphone wiring is connected properly. The wiring should be connected to the correct pins on the microphone jack and soldered securely.
5. Check the audio circuit: If the wiring is properly connected and there is still low sound, the issue may be with the audio circuit of the radio. In this case, it is best to take the radio to a professional technician for repair.

It is important to note that modifying or tampering with a CB radio is *******, and can result in fines and penalties. If you are not familiar with CB radio repair, it is best to seek the assistance of a professional technician.

look for other fingers that have been in the radio. then back track from there. It could be a switching diode thats burnt.

sounds like the volume control is bad if you cant turn it up or down

common problem bad solder joints in the vco circuit take it to a PROFESSIONAL

Jumper j15 needs to be cut.

99% of exports problem... the board may have loose connection on the voltage regulator.. if not may have blown the protection diode. IF you need help let me know.

To add 10Khz to your transmit frequency:

FIXED/OFF/+10KHz SWITCH: The left position puts the radio on
one of the three fixed channels that is selected by the channel switch
(6,19, or 21). This over-rides the channel selected by the 40 channel
knob. The right position adds 10KHz to whatever frequency you are ON.
In the middle, both features are OFF.

Otherwise, a radio tech would be able to retune the frequency inside the radio.

After adding 10KHz to your frequency, use the SWR control to check the SWR of your antenna.
Here's how:
SWR CAL CONTROL: Normally this switch is set to “PO”. Then,
during transmission, the meter indicates output power. To read SWR,
rotate this knob during transmission until the needle moves to the “SET”
point on the SWR scale. Then, while still transmitting, set the R.B./SWR
switch to SWR.

Ideal SWR is 1 but you'll want to be as near one as possible. An SWR of 1.6 or greater will make ineffective use of your antenna.
If in doubt, a radio tech has the required meters and tools to adjust the SWR/Tuning of your antenna.

the pll looks like flat magnet with a bunch of metal legs take it out with soldring gun go see if radioshak has one they have bunch of dioeds trans, switches ect....
