[Amps] Defining CCS

[kstover at ac0h.net]

This was my understanding as well.
By those definitions there is no such thing as a "CCS" amateur amp. "No Time Limit" is just marketing fluff.

Ok, I have had it with vague sales statements.  The following was used since at least 1955 and all amp experts know it.

CCS is Continuous Commercial Service.  This is true 100% duty cycle, BRICK ON THE KEY, rating indicating operations for 24/7/365 with no off times.
No sales talk juggling.

ICAS is Intermittent Commercial and Amateur Service.  That means typical on-and-off ham operations without long key-down transmissions (usually 10 minutes is called long).  This is NOT 100% duty cycle but indicates use of full power with limited key-down times and definite key-up times.

An amp can be called 100% ICAS by imaginative advertising writers, but that number is definitely not CCS.

It is helpful to hold to old established nomenclature for clear communication.
