Multi-Function Mouse Controller
What it does......................
1) Selects Channel UP or Channel DOWN (freq).
2) Selects Memory 1 or Memory 2.
3) Press to Talk
4) Selects 10 watt "Tune Up" facility.
5) The unit is fitted with an 8 pin plug which goes straight to the rig's microphone socket and from this plug there are short stub leads with "free" sockets for the mic input and foot switch TX/RX changeover, there is also a single lead which is connected to the 4 pin Molex socket at the rear of the rig which enables the 10 watt "Tune Up" facility which is very useful if you are using a manual aerial matching arrangement as I am.
The mouse employed is a cheap 6 button gaming unit which is dismantled and all of the components are removed from the pcb apart from the switches and the rotary encoder. The circuit shown below is employed utilising all of the original switches and there is plenty of room to fit the new components indicated, NB, the resistor R4 and diode D1 are fitted directly to the pins of the 4 pin Molex plug. The mouse and it's new functions can be seen below, it is very user friendly, neat and unobtrusive and fast in it's operation and can be moved about the operating bench with ease as it retains the very thin 4 core cable originally fitted to it. It will be noted that only 2 memory locations are available here, this is because I only require this, if the full 4 memory locations are needed then an 8 button gaming mouse can be used with it's associated resistors.
