[INRAD] 703-C problem

[Jay Bromley]

Hi Juha,
Since you can turn the slot on and off I will assume all is OK there.  You 
could test the filter in another slot if you wanted to.  One of my Inrad 
filters had a bridged solder pad and was dead.  No big deal, I just 
un-bridged the joint and re-soldered.  It happens from time to time so be 
sure look at that board very carefully.

Good luck and 73 de w5jay..
