285 TechConnect Radio Club -- NAØTC

The 285 TechConnect Radio Club produces an annual TechFest in November. The TechFest has 5 hours of presentations on technical topics related to amateur radio, plus a “demo corner” where club members show off some of their operating technology.

This year, the Fall TechFest will be held on November 3rd. Please note the change in location. If there are any last-minute changes to the speaker lineup, we will post them here.

We will not be holding the TechFest at the Lakewood Elks lodge this year. We do thank them for the use of their location in previous years.

The 2018 TechFest will be held at The Bridge Church at Bear Creek, 3101 S. Kipling St. This new location offers a great room, plenty of parking. and easy access from Hwy. 285. It's just up the hill East on Dartmouth from Kipling Parkway, on the South side of Dartmouth. Here is a map.
