The no. 10 would be for the newest 25 amp demand radios. Those greater
than 100 watts, HF. There are not many out there. And of course, stranded
wire is to be preferred for ham rigs, especially if you go mobile or
portable with it.
The UL listed electrical wires, of all copper construction are pure enough
for any radio use. The 100 per cent Oxygen free copper hype is an audio
marketing ploy.
You want to avoid voltage drop and consequent heating of a conductor. When
you pick a gauge that satisfies the wire table constants in those regards
you have the right gauge for the application.
It is true that the TT Scout can be finicky on DC voltage. I have observed
them giving problems when the DC battery supply at FD dropped to 11 volts or
less. Further investigation showed that if one could find a lower drop out
regulator, to install in the radio, you might increase the range of voltage
that will operate the radio without frequency jump or other problems.
However, if you are on battery power, and the battery goes to 11 volts, you
probably need to charge it then, rather than stress the battery by further
depletion.
