Essentially the same lumped values of L and C and hence the same tuning range. The distributed reactances inside the larger tuner are somewhat different because of component size changes, so there are some minor differences that show up on 6 meters mostly.
If you install the KAT500 Utility (available free on our web site), the individual KAT500 L and C values are shown on the Operate Page. You don't need the ATU to do this. Both tuners are switched L matches, with a series inductor and the ability to switch the selected capacitors to either end of the inductor. 73 de Dick, K6KR -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Gary Ferdinand Sent: Sunday, August 04, 2013 7:37 AM To: elecraft@mailman.qth.net Subject: [Elecraft] KAT500 vs K3 ATU I am considering getting a KAT500 to provide me with higher power auto-tuning. Currently, the KAT3 is capable of achieving a match on all bands using my open-wire fed 160-meter dipole, with some help from a 4:1 balun. I believe both tuners are T-matches, but I don't have enough information to judge whether the KAT500 will achieve the same matches that the KAT3 will. Can anyone give me the L and C values for each tuner?
