[TenTec] Fw: Omni 6+ keyer instability

["Jack Mandelman" <modeler@bellsouth.net>]

Thanks to all who responded.  I found the fix described in the TT Wiki 
to be most helpful.  I formed a small loop at the end of each lead of a 
0.01uF cap, placed the outer pins of the header to the connector through 
the loops and reconnected the connector.  No soldering involved and the 
keyer is now stable.
