Depends on your equipment specification.
If your equipment draws less than 10A,
you can try DC-DC chips.
There are various IC chip that converts from voltage to voltage. They are
easily available nowadays.

Not sure if it works on your system.
You can give it a try.

For a start you can try the following web on voltage conversion information,
to source for your needs,

I bought a used Icom-m710 SSB and it didn't come with any of the
necessary accessories to get it up and working. So I started looking
for a power supply, and the manufacturer of the radio recommends their
PS-66 DC-DC converter for a 24 volt setup to drop it down to 13.6 volts.
New, it COSTS ABOUT $1100!!!!!!

Anyone know of a cheaper way to do this?
