121. [AMPS] IMD measurement scheme (score: 1): Author: gdaught6@leland.Stanford.EDU (George T. Daughters); Date: Wed, 23 Jul 1997 08:27:51 +0008; hi tom, (snip) how do you recommend this be done? a combiner/splitter? a resistive mixer? (high power resistors would be necessary) what's your method? 73, George T. Daughters, K6GT -- FAQ on WWW: ht; /archives//html/Amps/1997-07/msg00182.html (7,937 bytes)

Daughters); Date: Thu, 24 Jul 1997 11:34:24 +0008; thanks to all who answered my combiner question! it seems like the "schmutz" level stays pretty constant... so that often means that the "signal-to-schmutz" ratio goes down when the power output is r; /archives//html/Amps/1997-07/msg00205.html (8,114 bytes)
