rf power spec

What is the continuous RF Power spec or limit on the Flex-6x000 series?
New Flex-6500 on order to replace (upgrade) Flex-5000A.  The Flex-5000A is 100 watts continuous which is great as a remoteham station.

RF Output Power: 1-100W nominal SSB, CW, FM, RTTY, Digital; 1-25W nominal AM

Hi Ron

Congrats on the update.  I kept my 5000A for a while until passing it on.

The 6000 series are also 100w (excepting 4m (6500) and 4m/2m (6700) which have their output power defined by the transverter setup).  Same robust output.

http://www.flexradio.com/amateur-products/flex-6000-signature-series/comparison-table/  is a nice handy chart summarizing features.

Hope you have as much fun with your new Radio as the 5000A.  I did want to write this comment as I did not fully accommodate how legacy my shack's legacy PC was, and though it ran SmartSDR (Preview at the time) "okay-ish" it wasn't until I replaced with with one of Neal's FlexReady computers that I was happy.  Just mentioning it in as there is no need for others to repeat the mistake I made that my old XP box was going to serve well just because it had a onetime great processor. 

The SmartSDR page has a Requirements Tab that both lists and also links a lot of information on the PC issue:  http://www.flexradio.com/amateur-products/flex-6000-signature-series/smartsdr/

All best, good luck and 73

This question, while simple in nature has a very complex answer.  There are multiple variables in play such as PA design, ambient temperature and the quality of air flow around the radio.

From the design standpoint, the PA in the FLEX-6000 is designed and rated for nominal 100W ICAS (Intermittent Commercial and Amateur Service) output.  ICAS implies that the transmitter is not designed to be turned on, operated at max power and left on indefinitely (that is CSS - continuous commercial service).  Under the ICAS classification for solid-state amplifiers, it implies de-rating to keep the device junction and case temperatures within their maximum ratings. Thus, ICAS suggests a limited operating or 'on' period followed by an 'off' or standby period of at least the same or longer duration.

The PA transistors in the FLEX-6000 are stout and well de-rated so that you should not expect any issue operating full duty cycle modes.  And there is also thermal protection built in that will shut down the radio before any damage can be done, which is really the most critical aspect of this question.

TNXs Tim,
That was the answer I was looking for.   Looking forward to my new Flex-6500.  The Flex-5000A was a great and real work horse of a radio.

Which model of final transistor does a Flex 6000 use anyhow?

Yeah you can't hurt it.
