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.

Where does the noise filter go? if it goes inline with the antenna, don't use it!!! It's bad for a cb radio.

The problem is that the V73 has a very sensitive receive. It is picking up noise in the car. Most likely the smog pump, or fuel pump.

Here are a few things you can try.

First, lets make sure where the noise is getting into the radio. It will either be getting in via the power wire, or the antenna.

To find out, here is what you do.

  1. Turn the car on, and the radio on.
  2. unscrew the antenna from the back of the radio. Make sure you do not key the radio without the antenna hooked up. It will hurt the transmit section.
If when you take the antenna wire off the back of the radio, the noise goes away, then the noise is getting in via the antenna system. Solutions for this could be any of the following.
  • Bad coax or connectors. Replace the coax with new coax.
  • Antenna not ground, or poorly grounded. If its a mag mount antenna, make sure the membrane on the bottom is in tact and there is nothing in between it and the metal of the car. this is how the antenna is grounded. If its a rigid mount to the body of the car, make sure it is free of rust or paint where it is mounted.
To find out if the noise is getting in from the coax, or antenna.
  1. Hook the coax back up to the radio. The noise will be back.
  2. Disconnect the coax from the antenna if you can.
If the noise goes away, it is the antenna. Try a new antenna. If the noise doesn't go away, its most likely bad coax.

Now if when you disconnect the antenna wire, the noise is still there, then the noise is getting in through the power wire.

Here are some things you can do to get rid of the noise.

  • Connect power wire direct to the battery.
  • Twist the power wire.
  • Put a not in the power wire right at the plug.
  • Use power line noise filter. It is a ground loop filter.
Some vehicles are noisy. You can't get away from it. Even with all of the solutions you may still have some noise. It's like that in my f150 pickup. I can't completely get rid of the noise, but most of it. In my blazer, I can hear the ignition noise if I do not use the ANL. In my friends dodge, he has no noise at all. Even without the ANL on. It's amazing.

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.

Tip

GET YOUR BLOWN UP RADIO BACK ONLINE.


When you cant get your radio turned on. All it does is blow the fuse imeadiatlly hooking it to power. Most likely it is the (reverse polarity diode). The quick fix is to locate your diode? This diode usually is back behind a coil wound transformer on your board inside the radio and in the general area of where the possitive ans negative plug wires solder to the board! Usually it is black with a silver band around one end. If you clip it on one end or remove it this will restore your radios power. CAUTION:: When doing this ALWAYS use a dual fuse power cord . This will prevent this from happening again by blowing the fuse first. Doing this procedure will remove your thermal protection to the radio thus making it wide open to being fried for good if it ever gets hooked up backwards again. This is my reasoning for the dual fused power cord. Good luck!
