Go to the QRZ.com website & look under the menu item VANITY CALL SIGNS. I think it directs you to the F.C.C. ULS website, also. If I remember correctly it cost $16.20 to get your Vanity Call from the F.C.C. You have a choice of 1x3 or 2x3 calls,since you are a General. You can even find out whether the callsign you want is available or not for your first choice & you can list up to 10 choices & see if they are available also,I believe. Then once you pay your fee you can track the status of your application & whether your likely to get your 1st choice or not. Hope this helps ! If you have any more questions, please feel free to e-mail me !
73 & Gud luck,
