The difference being that, with enough determination, the brick is edible..

Did anyone else notice the Alpha ad in QST over Christmas showed a fruitcake
on the key instead of a brick?

I can make you a very long list of amps and their finals which are destroyed
by key down at full ham power for 10 minutes. I can make a long list of
transceivers that will not run their rated power CCS. A K3 will do that by
common experience, but Wayne ain't guaranteeing it. Typically we don't

Lyle is correct (as usual). It is not a firmware function until things get too
hot for the fan to handle.

The amount of power required is a function of propagation and intended
recipient. I can't say in advance of an *event*, how much power will be
required. If 100 watts isn't cutting it on the first delivery attempt (it
usually does), I'm not fooling around with 250 watts...I'm going straight to
500
10 min key down out of a total of 15 min is a duty cycle of 0.6667 which
seems pretty good to me. I don't think I want to pay for a CCS rating
when I'm really very ICAS. RTTY is my most demanding mode. I was a bit
concerned about my K3 on RTTY so I wrote a little Perl script to go

I'm a licensed Navy MARS operator. It is not uncommon to have very long
digital messages that need to be sent using digital modes that will take
longer than 10 minutes to send. This limitation pretty much eliminates this
amplifier from being able to be used in my shack for MARS purposes. Now

I cannot think of a way I operate that would exceed a 10 minute
transmission.
Other than a 'Fault' ?
