KAT2 Question....is mine working?

I just finished my KAT2, everything cal'd and aligned according to the
manual using my DL1 dummy load.

When I hook the tuner up to my (10 - 40M) attic dipole and use the tune,
I am expecting to hear some relay sounds, but nothing? Within a few
second the tuner turns off and give me a (allways) SWR of 1.0 : 1 across
all bands.

The same is true, even 80M.

I really expected to hear some kind of clicking from the relays using
80M, given what it is feeding into.

When in the cal mode I can get each one to click when using ht ATU
parameters L0 to L8, C0 to 8 and N1,N2

I was able to get C55 down to 004 and R1 and R2 are aligned with what
power the DL1 chart reads for voltage vs. output.

Thanks,

Chuck - K3TNT

RE: KAT2 Question....is mine working?

Chuck,

Did you ever hear the relays click once? Like the first time you attempted
a TUNE with that antenna.

The KAT2 remembers the tuning settings for each band (on each of ANT1 and
ANT2), and when that band is selected there are some clicks from the KAT2
when the bandchange is made along with the bandswitching relay clicks from
the K2, so it is hard to tell them apart.

If the SWR is already at 1, then further presses of TUNE will only result in
an occasional relay click if any at all - becuase it is already tuned.

You may have no problem at all - just the nice operation of the stored
settings for the KAT2.

If the wattmeter in your KAT2 is properly set for reflected power, all is
working OK.

RE: KAT2 Question....is mine working?

No, that is why I posted.

Perhaps I should be pleased, but instead I am bothered.

Last night in testing/playing, have gone to the low and high end of
every band and tuned. Always with the same result. I hear the start/stop
beep (but no relay clatter), then 1.0 -1 as the setting.

I have changed the display mode to SWR and swept portions of the band
in TUNE (at 1 watt) with the same result 1.0 - 1 everywhere?

One other else thing I noticed (last night), Right now Ant 2 is not
connected, my plan is to have that connected to the DL1, but when I was
working last night it was not. I was listening to 40M, the band seemed
good and was on a pretty stong signal. Then while playing with the
controls, I decided to switch over to Ant 2, expecting to hear silence
(the K2 is quiet), to my surprise I heard the strong signal breaking in,
then being squelched.

I thought the isolation between Ant 1 and Ant 2 should have been high
enough to avoid this.

Then 1 went up in freq. abit around 7060 kHz and found that even noise
would break through occasionally, this again surprised me, I could
perhaps understand a strong signal, but just noise.......?

So my concern is that on transmit I am getting some spill-over/leakage
into the other Antenna channel.

Thanks, again.
