Re: [Elecraft] KAT500 "Bypass SWR"?

[Dick Dievendorff]

Yes, that's the SWR measured with the ATU in bypass.  That's the first
setting we try in a "full search tune".

>From KAT500 Utility Help for the Operate page:

Bypass VSWR

The VSWR measured when the ATU was last in "bypass", an estimate of the
antenna's "untuned" VSWR without any ATU inductors or capacitors.

Subject: [Elecraft] KAT500 "Bypass SWR"?

My KAT500 utility program shows the tuned VSWR, generally a low number, and
it also shows "Bypass SWR". Is that a reading of the feed line SWR without
the tuner in the circuit?

Re: [Elecraft] KAT500 Bypass?

Hi,

No compensation is necessary. I have a Ridge Equipment dummy load on one of
my ports and it measures 1.02 with an LP-100A in SWR in bypass mode on 10m.

Re: [Elecraft] KAT500 Bypass?

[brian]

I once did a TDR measurement of the distance between the input and 
output in bypass mode.
It comes out to be about 18.Interesting,  I would have expected 
much less.

[Elecraft] KAT500 Bypass?

[Jim Miller]

When the KAT500 is in Bypass are all elements really bypassed?

Or are they bypassed with compensation for the internal paths?

Is there an internal bypass calibration required?
