[Elecraft] potentially interesting (sorry, bad pun)

Steve,

It looks like 'specsmanship' to me - I looked hard at the 5 amps continuous
rating and then looked at the high current duty cycle specified and
concluded that it will not support a continuous string of dots no matter how
you slice it.  Duty cycle/sec is a unit of measure that I have never heard
of and does not make any sense to me - duty cycle is a ratio, and seconds is
time - what do you call a ratio divided by time?  I guess it could be
related to frequency (= 1/t) - a ratio is unitless - as I said, it doesn't
make any sense to me.

It may be a 5 amp supply with a BIG capacitor.

For the price, there are other switchers out there in the same price range
that will provide 20 amps ICS with no problem.

73,
Don W3FPR
