1. [Amps] IMD & ALC's (score: 1): Author: "craig" <craigs99@iprimus.com.au>; Date: Sat, 3 Jan 2004 02:23:04 +1100; Here is a great link discussing the IMD performance of modern radios and poor ALC design. Some very interesting IMD measurements on some radios. http://antennspecialisten.se/~sm5bsz/dynrange/alc.htm; /archives//html/Amps/2004-01/msg00019.html (6,793 bytes)

One problem is trying to convince the ignorant that mo' ALC is not mo' betta. Another problem is manufacturer's owners' manuals which recommend using a certain level of ALC. - suc; /archives//html/Amps/2004-01/msg00020.html (7,312 bytes)

Running almost no ALC helps. ** Without some form of ALC, excess IMD is a virtual guarantee -- unless the operator religiously rides he; /archives//html/Amps/2004-01/msg00024.html (10,943 bytes)

NEVER running into "factory" ALC helps more. :-) find and bad Not necessarily. Just use some form of hard limiting before the "box".

However, many people (including me) currently use VOX and transceiver-controlled bias switching.
