Almost every Tuesday, Tom Fry (KF6Q) and Mike Bode (WB6CLZ) hold a 1 hour session (that usually runs long) covering various technical topics related to amateur radio.  I record as many as I can and post MP3 files of the sessions, here.  Feel free to right-click on the links to download them, or click on them to have them stream to your default MP3 media player.

If you would like to join in live, Tech Tuesday happens on the Big Bear Lake, California, repeater at 7PM (or 19:00) Pacific time.  Tune into 147.330MHz (+600kHz) with a P/L tone of 131.8Hz., the K6BB repeater owned and operated by the Big Bear Amateur Radio Club (BBARC.ORG).
.  You can also tune in on Echo Link.  If you are a licensed amateur and not familiar with Echo Link, check out www.echolink.org.

The recordings are listed descending (newest on top). There is a key word search. Click on the runtime to hear the selection...
