Juma PA-100D Firmware Version: 4.01a

[5B4AIY]

There is now a new version of the firmware for the Juma PA-100D. This is a maintenance build, and whilst it does not add any new features, it closes a very remote 'Window-Of-Opportunity' for an error to cause the serial port to send garbage characters to a connected transceiver in the AUTO frequency mode. Note however, that in more than 10 years of operation and literally hundreds of user downloads I have never actually encountered this potential fault, but in the interests of defensive programming I decided to eliminate the possibility.

NOTE: I have now been supplied with the source code of the modifications from Rowaves Technologies, and can confirm that it is merely cosmetic, and has no impact on the operation of the amplifier. As a result, this version of the firmware should work perfectly well, but please note that it has only been tested on an original Juma PA-100D kit. As with all firmware updates, therefore, use at your own risk. (23-DEC-2021)
