Anne's Site: Cape Cod and more
On a cool November day, as Ham Radio operator N1BE, I worked on the 53.81 MHz transmit antenna of the W1BRI repeater. This repeater is part of the Minuteman Repeater Association (MMRA) system of eighteen repeaters.
Some software I have worked on is at github;   my C.V. is at LinkedIn.
