Beware!! The stock SB-220 does NOT have a catch diode across the relay coil. As a result, it can fry the switching transistor or relay in the transceiver. Make sure the diode is in place before hooking it up. 73, Scott K9MA -- Scott Ellington Madison, Wisconsin USA sdelling@facstaff.wisc.edu -- CQ-Contest on WWW: http://lists.contesting.com/_cq-contest/ Administrative requests: cq-contest-REQUEST@contesting.com |
