[Kenwood] TS-480 extended transmit?

[Alex Eban]

The old marine band  is at 500kHz, I know, I've been there.
The power amplifiers of Kenwood are not designed to operate under
approximately 2 MHz by choice of core materials of the transformers. Their
inductance is too low to operate efficiently a tower frequencies. Coupling
and filter capacitors are also calculated for 2MHz operation also. If I
remember good, there are also band limiting filters  in the `480. as far as
I know, no Kenwood wad made to work under the BC band frequencies (530-1610
kHz)-receive only, no transmit there.

Has anyone enabled extended transmit for the TS-480 below 1.7 Mhz?

If so, how?

I do not mean that mod that is presently available to enable the rig to
transmit from around 1.7 Mhz through 60 Mhz., or the so-called MARS mod.

I mean down to 100 Khz. or about the same range as the receiver covers.

I am asking for some folks who belong to an LF experimenters group which has
a license to operate in the old 600 meter Marine Band and would like to use
that rig there.

Thanks,
