A 1.5 A regulator isn’t going to handle the 12 to 20 A drain of an HF Radio.

Why not use a 7812 three terminal regulator? It will accept up to 30 V
on the input, deliver 12 V on the output at 1.5 amps. These cost about
$1.50 or less. If one needs more current then add a 2N3055H as a pass
transistor for up to 5 amps of current.
Another choice is a regular AC 120V p
My club used a $20 buck converter from Amazon for FD. Used two AGC batteries in
series and dropped to 14.1V. Unit is 20Amp and handles input voltage up to 40
and output from 5-35Volts.

I just bought a 24V 3.5A battery to power my CPAP machine when AC isn’t
available. Would be nice if I could use it to power my KX2 or KX3. 24v-12V down
converters are cheap, but the only 24V-13.8V one I’ve found so far is an order
of magnitude more. Does anyone think the extra cost is worth it i
