The ICOM V 80 is a rugged, basic 2 meter HT and here are the instructions to enable the MARS/CAP coverage.

1. Remove both the antenna and the battery pack

2. Remove the 2 screws on the bottom of the radio.

3. Remove the nut on the BNC antenna jack.

4. Carefully lift the front cover and disconnect the speaker plug.

5. At the bottom right of the LCD Display near the power switch there is a single diode, remove it.

6. Reassemble the radio in reverse order.

Thats it, There is not even a need to reset, just turn on the radio and you will have coverage from 136Mhz to 174Mhz on TX and RX.

    My first thought was the i.r.s. may be interested in a long term money making scam without proper taxes being paid..probably more than electronics involved.
  • @ Toll_Free:
    My first thought was why hasn't someone paid him a visit. I mean, his address is posted above.
  • @ beakster1715:
    Good news! I opened an appeal case after eBay sided with superhawkwss6. I also opened an IC3 case & sent that information to eBay. Within an hour they responded, reversed their decision and returned all of my money. Unfortunately, superhawkwss6 stole my CB radio and eBay will likely not suspend or close his account, but rather allow him to continue his criminal activity. I think I'll still file a report with our sheriff's dept (the sheriff is a friend of mine) though I know this type of crime isn't worth their time. This guy needs to be stopped and I'm certainly going to do my best to make that happen.
