The ASIC is a 'black box' and we can't really determine the rf output
frequency by looking at the chip itself.

However, the 3 driver chips are 20 watt AF amplifiers. That tells us
that hte output has to be less than 20 Khz.

The wall wart looks physically small, so it's a reasonable to assume
the output power does not come anywhere near 60 watts...

I looked the pictures on the fcc website and I see that the coils are
not in a transformer configuration....they appear to be one coil for
E-W vertical polarization, one coil for N/S vertical polarization and
the third chip drives the coil for omnidirectional horizontal
polarization.

Since the chips aren't on a very large heatsink, it is probably
possible to easily increase the output by properly heat sinking the
drivers and by increasing the drive to each amp stage (after checking
part 15 rules and regulations).

My guess is that the coils will easily withstand the additional output
power.

Once again, I say thanmks to all who commented and helped me figure
out what was inside that unit.

The ASIC is likely a PLL synthesizer, so the output frequency isn't
necessarily an even multiple of the MO frequency.
