1. [AMPS] K2RIW Amps (score: 1): Author: gjerning@flash.net (Arne Gjerning); Date: Sat, 24 Feb 2001 19:42:11 -0700; When I helped operate EME station at the 150 ft Stanford Univ dish in the late 70's, the amp on 432 MHz was a RIW (2ea 4CX250B) and it read 900W out to a Bird wattmeter. I would not have believed it; /archives//html/Amps/2001-02/msg00326.html (7,721 bytes)

The practical limit for good linearity is about 500W in strict class AB; /archives//html/Amps/2001-02/msg00329.html (8,402 bytes)
3. [AMPS] K2RIW Amps (score: 1): Author: 2@vc.net (measures); Date: Sun, 25 Feb 2001 08:03:55 -0800; I ran a pair of paralled 4cx250Rs on 2m SSB. The tank was 1/4 wave. With a screen current of c. 5mA (@400screen-v), the linearity was good. Output was c.900w PEP on SSB. 10w drove it. cheers - Rich.; /archives//html/Amps/2001-02/msg00331.html (8,625 bytes)

5. [AMPS] K2RIW Amps (score: 1): Author: drkirkby@ntlworld.com (David Kirkby); Date: Sun, 25 Feb 2001 20:20:30 +0000; I think in these arguments (anf it seems to have developed into that), it is essential to define what 'good' is. It's a bit pointless saying 900 W at good linearity, without defining what 'good' is.; /archives//html/Amps/2001-02/msg00334.html (9,051 bytes)
6. [AMPS] K2RIW Amps (score: 1): Author: k7fm@teleport.com (Lamb); Date: Sun, 25 Feb 2001 13:38:35 -0800; I think for EME work, good means putting out enough power to be barely heard by someone 100 miles away after bouncing off the moon. Quality is less important than being heard. Longevity of the tube i; /archives//html/Amps/2001-02/msg00335.html (8,282 bytes)
7. [AMPS] K2RIW Amps (score: 1): Author: drkirkby@ntlworld.com (David Kirkby); Date: Sun, 25 Feb 2001 23:02:19 +0000; But Rick did say 'good linearity' not 'good power'. He defined the power (900 W), but it was the linearity to which a rather subjective measure (excuse the pun) 'good' was used.
