I recently acquired an HL-1.5Kfx that is unresponsive to front panel controls and to external PTT controls to activate the amplifier. I have confirmed that control inputs are reaching the CPU and that the CPU oscillator is running. I have also confirmed that the CPU reset is high. Symptoms would indicate a CPU that is not running.
Would anyone know if replacement CPUs can be had or if the firmware is available to burn new ones?
Thanks!
