yeah and couldnt it be just a simple load problem.
if the power supply was marginal, the load of the strobe added to the
increased power drain of transmitting could just bring the supply down
far enough to cause the unit to reboot (for want of a better word)
I have seen a fire water bomber that periodically lost all electrics
because the start up drawdown of a 12 volt dc pump motor tripped the
circuit breakers. had the chopper pilot's attention centre stage until
someone put a multimeter on it and identified the cause. instantaneous
25 amp draw through a 15 amp circuit breaker :-)
doesnt the guy's comment that he tested with a battery charger hooked
up sound a warning bell? dicky battery that needs replacing or dicky
generator or dicky regulator?? of the three I would guess battery.
