Up to 6 radios Matrix switch box....

 The last 10 years I'm using a homemade matrix switch to share my Microphones, keys, and sound blaster to my radios (up to 6 of them).

 Yesterday  I make one more modification for my straight key connections and i decide to share this idea with you.

 It's just a 19" aluminum box with    switches that makes the routing  pathetically.

The heart of the box is the galvanic isolated audio input-output circuit and the optocoupled PTT switch.

Almost any combination of RX-TX is possible and the share of my shack's accessories to any radio is attached is a snap....
The project is designed and constructed by me...   Hi Hi...


 If you have more than 2 radios try to make it...
