[Elecraft] KAT500 vs K3 ATU

[Dick Dievendorff]

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.

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?  

Thanks,

Gary W2CS
