[Boatanchors] Mic switcher

[Jim Wiley]

Ed et al -


My friend KL7DTH uses a commercially built box called the "Multi 
Switcher"  by an outfit that calls itself NCS.  It selects from one of 4 
inputs/outputs and then connects that to one of 4 rigs, both mic and 
headphones.   After looking at that box, which works well for him, I 
decided to brew my own.   The unit I came up with takes one of 5 inputs 
and routes it to 5 rigs, switch selected.  But, unlike the Multi 
Switcher, I decided to  route the audio inputs (mic) and outputs 
(phones/spkr) separately.   My box has a 5 position input switch (mic 1, 
mic 2, phone patch, 2-tone test gen, and auxiliary bus/tape deck) and 5 
separate DPDT center-off switches for the outputs, routing each rig to 
either speaker or a headphones bus (or off).   This allows me to have 
more than one receiver/speaker active (the Multi Switch does not).  I 
also have a "repeat" switch that selects one of 5 receivers or "off" and 
routes that to   the auxiliary bus so I can connect any receiver to the 
mic input of one of the transmitters.  Not often used, but handy once in 
a while.
