The KAT500 is a "beefed up" version of the KAT3, using very similar value components (in pF and uH) but larger current and voltage capacities. The range of antenna impedances that can be matched are quite similar. The KAT500 firmware algorithm started with the KAT3 algorithm, but the KAT500 must also work with other transceivers and a high power amplifier, so additional capability is required. Significantly more memory is available for storing antenna tuner settings. 73 de Dick, K6KR -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Andy Wood Sent: Wednesday, March 28, 2012 10:46 PM To: [email protected] Subject: Re: [Elecraft] KAT500 vs KAT3 Matching Range Hi Bob, The KAT3 tuner has one of the widest matching ranges I have ever seen from an autotuner. Only maybe twice has it not matched what I have connected to it. I suppose I want to know if the KAT500 is a "beefed up" version of the KAT3, using the same value components and firmware algorithms.
