That is just pure nonsense (the up vs down part). You can buy a 30W
(15V @ 2A) dc-dc converter for $62 from Mouser (search for
UHE-15/2000-Q12). The description says the input is 24V, but it really
is 9-36V, which should cover just about any battery you want to come up
with. The thing is 88% efficient and occupies 1.5 in^3. You can buy
lower power ones even cheaper. If that makes your 14V heart feel
better, go for it (it won't damage your radio).

Get one of these for $45 and it will take your 12 V input and upconvert it
to 14V, handle 2A and be about 83% efficient.

I wish I had been available two years ago when I built my own 13.9V
upconverter.

Did you use it with your glider transceiver? How has it worked out, and
do you have any problems with noise in the receiver from the converter?
