-====== IC-R75 ======
-===== - Details =====
-===== - Repairs / Mods =====
-  * -5V DC/DC converter
-    * capacitor failures
-  * "Turn Off" fault - due to overheating of 13V regulator
-    * Cured by
-      * Reduce input voltage to 13.8V
-      * Improve heatsinking of regulator IC to chassis
-===== - Remote Control =====
-  * connected to ''shack'' server via RS232
-  * ''shack'' server running Python netradio ''server.py'' to give TCP/IP network control
-  * ''laptop'' PC running Python netradio ''client.py'' to give user access
-    * Available controls: <code>gm4slv@laptop:~/Python/PythonProjects/netradio $ python2 client.py
-There are currently 1 radios connected.

-q    : quit
-IC-R75 >
-</code>
-  * audio via network using ''PicoPhone''
-    * running on shack ''laptop'' via ''Wine''
-    * running on Windows laptop //natively//
-Remote control is achieved via a SSH connection to shack ''laptop'' to run the netradio ''client.py'' and the RX audio can be heard via PicoPhone.
