If you have your scanner there with you, you should be able to hear most of the base. I know most of the agencies on the base were in the VHF High band, but we were encrypted. I discovered that when I was workin' the graveyard shift one night, had all of the channels on our HT's, so just switched to each channel and searched for them, should've written them down but didn't think anything of it. Do they still have that drive-in on base? I know it's only been a few years but I've been out of the Corps for two years already and still can't believe it. Actually, it will be two years tomorrow.
But anyways, you should be able to hear Naval Sec. and Base FD. We worked with those guys quite a bit.
