This is another major release, as it introduces the ability to remotely adjust the squelch of the VOTER/RTCM.

By default (originially), the Squelch Pot (R22) just sets a voltage on an ADC line of the PIC. Based on the ADC value read, the setting of the squelch is determined.

It is often desired to be able to remotely tune the squelch of the receiver, without having to drive to the radio site to "diddle the pot", and as it turns out, this is relatively trivial to do in software, by directly setting the value that would normally read from the ADC.

In addition, there is a "squelch tunable" in the firmware, called "hysteresis", that will be brought out so it can be adjusted without having to recompile the firmware. By default, this has always been set to "24", unless you specifically changed it, and compiled your own firmware.

Therefore, this version adds a new (S)quelch menu, that lets you adjust the squelch level and hysteresis remotely.

Note, due to space constraints in the PIC, the option to display the "diagnostic cable pinout" has been removed from the diagnostic menu. This allows us to have the option to select using the hardware squelch pot, or software squelch pot.

When using the software squelch setting, the change is immediate, but do not forget to save the EEPROM settings (99) when you are done your adjustment, to make it permanent.

NOTE: You will need to manually set the Hysteresis to 24 and save, if you use this version. Hopefully, this will be resolved in a future release to set it to 24 by default.
