The CVARC Hamfest is THIS Sunday, August 6, 2017 8:00 am - 1:00 pm in Cedar Rapids, 5000 J St SW. Hope to see you there!
Please come get this if you want it - I forget the details but it's a multi-band vertical antenna - free to first person that can pick it up.
FYI – SEARC has been notified that an operator is running cross-band repeat with an unprotected input on the Humbolt VHF SD Link repeater. This is causing issues with it’s operation and kerchunking across the entire system. For this reason Humbolt VHF has been removed from the Link for the time being. All other repeaters continue to function normally across the state.
If you are aware of anyone running in this configuration, please contact WOSD to help resolve the issue.
There will be a VE testing session on Saturday, July 29th from 9am-11am, at the Murray County Government Building in Slayton, MN. Entry door is on Broadway Ave. between 28th and 29th Street. There is a $14 testing fee. Please email wb0zso@arrl.net for more information.

Great swapfest. I found this gem in a box of older free '73 and CQ magazines. Made it all worthwhile. I love a good swapfest.
This is a simple touch-tone (dual tone) generator circuit. Instead of a keypad, the two tones are selected by turning on DIP switches. Press the button to turn on the power. The output goes to a single NPN transistor which is the speaker amp. Once hardwired, it is useful for many remote control projects.
Don't throw away old landline phones without harvesting some parts. The 5089 IC is the dual tone (touch-tone) generator, which together with the 3.58MHz crystal can form a simple circuit that is the basis of many good remote control projects.
