[Elecraft] KAT500 vs KAT3 High SWR Ability

2018-10-31 Thread James Bennett via Elecraft
Recently assembled a KPA500 / KAT500 pair and hooked ‘em up to my 2010 K3. I’m wondering what the capability of the KAT500 is versus that KAT3 internal K3 tuner, as far as what each will match. I ask this because the KAT500 does a horrible job on 17 meter. The best if can do is about 2.3:1, wh

Due to issues with Expert 2k-fa, I compared many SWR devices. SWR metering in K3 is not very accurate although it is good enough. Without KAT3 turned on, SWR in K3 may indicate 1.0 while LP100 shows 1.5, and vice versa. When if K3 indicates 1.0 it may be from 1.0 to 1.7. Additional problems are cau

As Eric recently explained to me, the KAT500 is based on the same design as the ATU for the K3--only bigger! So, yes it should have much the same spec's, which means something like a 10:1 SWR capability. Actually, Eric noted that, provided you a somewhat closer SWR variance, like 3:1 or better

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. A

According to the K3 manual (page 73): "The KAT3 provides a wide-range, switchable C-in/C-out L-network for matching a variety of antennas with SWR as high as 10:1 (100 W) or 20:1 (10 W)." so the KAT500: "Typical matching range at 500-600W is up to 10:1 on most bands." is comparable to the KAT3

Hi Scott, Thanks for the reply. I did read the information on that page before posting. Unfortunately the information there does not answer my question. Andy VK4KY -- View this message in context: http://elecraft.365791.n2.nabble.com/KAT500-vs-KAT3-Matching-Range-tp7416153p7416182.html Sent fr

Will the matching range of the KAT500 be the same as the KAT3? If not, is it better or worse? Andy VK4KY -- View this message in context: http://elecraft.365791.n2.nabble.com/KAT500-vs-KAT3-Matching-Range-tp7416153p7416153.html Sent from the Elecraft mailing list archive at Nabble.com.
