Unless I am mistaken, the top light indicates recieving or transmitting, the bottom indicates high swr. Bottom should not be on.

Quick question, is your antenna shaft insulated from the mount with a nylon washer? Thats the most common cause of high (>3) swr.

Thats OK, as long as it is a screw on type (looks like it to me). Have you tuned the swr at all?

no i have not tuned it nor cut the antenna at all. i have been reading about this and it looks like i need to get a swr meter. or if someone already knows how long my antenna needs to be? i can cut it. right now it is 46-1/2 in long.

You have an internal swr meter.

Set the channel to 20.
Set the S/RF-SWR-CAL switch to CAL.
On the meter look for the red arrow next to where it says CAL.
Key the MIC and adjust the SWR CAL knob to align the indicator with the arrow.
With the MIC keyed switch the S/RF-SWR-CAL switch to SWR and you want to read less than 3. The further to the left the better.

Do this and tell us what you find out.

Here to help.

Trons are my life.

Things to check:

1. Check your antenna connections for mis-aligned threads.
2. Check to make sure the pins in your connectors are not bent or loose.
3. Make sure the connections are tight.

If you still have bad VSWR we will chack some other things.
Do you have a Digital Volt Meter?

You do have a great radio. It's one the most popular sold. Do you have the MOS-FET upgrade? The upgrade bumps it up to about 35 Watts.

Most parts are available through Radio Shack or any CB/HAM shack.

Here is a write-up (not mine) for doing the MOSFET upgrade to your transceiver. There is soldering involved; if you are not a seasoned solderer this is not the project to learn on. You will need to find a twidget near you. Any HAM guy would probably do it for you for a couple cold beverages just for the fun of it.(But don't give him the beer until he is done or you may be receiveing radio free saigon before he is done..

MOSFET Supertune (29LTD classic and newer):
Replace stock final with IRF520 MOSFET transistor (pin-for-pin match when installing).
Remove R56 and in its place install a 470-ohm resistor in series with a common switching diode (1n914 or similar), with the banded end of the diode towards the front of the radio.
Remove C53 and solder it across C59.
In C53's place solder a 3.3k resistor.
Remove C61 and solder it across C62.
Remove C126.
Remove R55 and solder a 22pf cap in its place.
Remove the slug from L14.
Replace C71 with a 33-47uf cap.
Turn VR4 (AMC) counterclockwise fully.
Gently spread L13 and L12 and tweak the spreads for best PEP when modulated.
Tweak L20 and L17 for best PEP when modulated.
After tuning is finished, set VR4 to half-way.

Loose my license and get a multi-thousand $ fine? I'll pass.

Part 97 of the FCC states 4watt max for CB band, as well saying changing FCC approved devices is a violation.

Know what you are doing ;)

Well, there is that...

Did you get a chance to check your cable?
