Juma PA-100D v1.05n

This new version of the firmware adds a new feature, as well as optimising some of the calibration and user configuration prompts.
Selectable Start-Up Page Display
As a result of a request for the Juma TRX-2, I added the facility to allow the user to select which page is displayed on start-up. This feature has now been 'ported' to the PA-100D. There is an additional page to the User Configuration menu, where you can select which of the measurement pages is displayed on start-up as the default, RF Power, SWR, I/P Voltage, Amplifier Current, or Temperature. If you turn the Graphic Display off, then the scale displayed will always be the instantaneous RF O/P power. If the Graphic Display is on, then the measurement is displayed in relation to its currently set trip limits. Some users prefer the amplifier to start-up displaying the input voltage. If you do not wish to use this feature, then simply leave it at its default setting, which is O/P Power.
In order to avoid having to use an additional EEPROM location to store this setting, I re-used the somewhat redundant pa state. This was always set to the STANDBY setting on start-up as a safety precaution, so it was not really being used. This flag is now a global, and the EEPROM location thus relinquished is now used for the Start-Up Page setting. (See file juma-pa100.c for details, if you are curious.)
In addition, a number of calibration and configuration prompts have been modified to be a little more explanatory. As there are no EEPROM changes, this version can be safely loaded over a previous version, but, as with all firmware updates, it is a wise precaution to note your existing calibration and configuration settings first. If you are updating from an original version of the firmware, or from one of my earlier versions, this will involve an EEPROM mapping change, and thus in this case you will see a 'Checksum Error!' message on initial start-up. This is normal, and only occurs the first time. Unfortunately you will then have to re-calibrate, as this error forces the standard defaults to be loaded.
