Because FM requires continuous power, I recommend that you have a power
supply capable of 15 amperes ICS if you plan to use it in your shack. If
you want to use it to power a 100 watt transceiver as well plus some
additional accessories, get a 50 amp supply, but in either
case, be certain to evaluate how much rf interference a switching supply
puts out.

50 amps is not necessary for a 100w transceiver. (Was that a typo, Ed?) I
think the most I've so far ever seen recommended by a radio manufacturer for
100w is 22 amps. For example, my Astron 20A (20 amp - duh) supply powers my
IC-735 just fine. I understand what you mean, though, about 2m being
continuous, as opposed to CW and SSB being intermittent on transmit.

A 20 amp supply would be what I'd recommend for the 2m 50w radio in the
shack.
