And has anyone noticed that the front panel indicators on the Alpha amp
shown in the recent ads seem to show 1500 watts out, with pretty close
to 2500 volts and 0.6 amps on the meters. WOW! !500 watts RF out for
1500 watts DC in. 100% efficiency!! There's a good mark for Wayne and
Eric to

I cannot think of a way I operate that would exceed a 10 minute

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

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
through a
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

The real question is whether or not the 10 minute duty cycle is a function
of heat or is it a timer / firmware controlled function?

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

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
