Meeting Announcement

Our next meeting of the 50MHz and Up Group of N. Calif will be a holiday dinner party on Thursday, Dec. 1, 2016 at 6:30pm (see below). Please do not come to the usual TI conference building as no one will be there.
The party will begin at 6:30pm at the Black Bear Diner in Sunnyvale (415 E. El Camino Real, between Fair Oaks and Mathilda), in the back room. As in past years, we will have a (optional) mystery gift exchange/lottery. If you want to join in the fun, please bring a wrapped (festive or brown bag/box; your choice, just so that we can't see inside) mystery gift. It should be entertaining, interesting or useful to a microwaver/ham; it does not need to be valuable.
