START HERE: To use GRMS frequencies, the FCC requires you to obtain a license. To get a license you don’t have to take an exam, but you will need to fill out the required forms and send your payment.
OBTAINING AN FRN:
Use the LOGIN button that was located just BELOW the REGISTER button on the previous step. Use your new FRN number and password.
After logging in click on the APPLY FOR NEW LICENSE OPTION in the upper left corner.
From the drop down SELECT SERVICE menu pick GMRS which is the LAST ONE on the list with code ZA. (No idea why it's ZA)
Fill out your contact information as you want it to appear on your new GMRS license.
Continue following the directions and pay your fees. Wait a few days and your new GMRS license call sign will be emailed to you.
