Red RX/TX and red ANT light on my CB


Well,first hand ,some cobra radio,s have red some have green RX/TX lights, but are you modulating? Some green lights turn red. What is your standing Wave on the antenna,s? You need to check it and the output of the radio. To do this you need a watt or field strenth meter. Can get one at Radio Shack. Your standing Wave is ok as long as it is below a 2. That has to be done on the antenna. ..hope this helps...

148 cobra with no modulation


possably corrosion on the pins of the plug into the radio, unscrew, push in and out a couple of times, and try again, maybe a break in the cable where it flexes the most. or faulty antenna

Changed battery and still does not work - hear pinging in computer


There are buttons on the transmitter/receiver and the mouse(small red on bottom). Turn off the mouse. Plug in the USB Tx/Rx and hold down the button. Then press the red button on the mouse and hold for one second. Do this until the rapidly flashing light on the Tx/Rx slows down. The unit's frequencies are then encoded/decode and can communicate.

Distance from TX to RX possible too great


There are a couple more questions
  1. Is it a removable antenna on the wireless router e.g. 5db or 7db gain. you could just get better antennas to increase signal strength for distance.
  2. E-bay has a linear antenna you assemble with a usb wireless network adapter attached.
