    It's an old De-rating term that started in the tube days.  Intermittent Commercial Amateur Service (ICAS).  The other rating is CCS (Constant Commercial Service).

    Yes, I hope that flicks will come up with a linear that is a little bit more affordable for us Po folks.

    Intermittent Commercial Amateur Service (ICAS) vs CCS (Constant Commercial Service)?  Interesting.  Now I wonder what the difference is.  ICAS is considered 100% duty cycle?  If so, it sounds like there must be some limitation.

    This is one more area were old standards have not been revised to meet modern electronics. As we now know the Power Genius will key down for hours without working very hard at full power.

    It is like the old standards the FCC in the States place on companies when getting certified, the power padding. Why wrong for state of the art amps that produce clean power at high power.

    I haven’t seen a “key down” rating for the PGXL, but the KPA-1500, which is also rated at 100% ICAS (for 100 % duty cycle modes) is spec’d at maximum 5 minutes “key down” from 1.8-30Mhz, and 50 seconds at 50Mhz.

    Of course, the 100% ICAS rating for the PGXL could be too conservative and the amp may in fact exceed it as has been stated.

    Interesting definitions.  I guess this really says it all, "In this context, "100% ICAS duty cycle" can be a little misleading, since the very term ICAS implies some de-rating by time (duty cycle < 100%) for rated power output...".

    I don't know about the rating either, I talked to people using the PGXL with two Flexes transmitting at full power with out a break for as long as the contest runs. So I don't know.

    Yes.  We have a beta team using them and providing feedback that is being used to improve the product.  We expect to start shipping the amps in low quantities starting next month and ramping up shipments (this is how we roll out all new products)
