KAT 500

I placed my order. I hope to be in the 1st run. I have a question or two
for the guys who saw it at Dayton.
How is it cabled. Not the antenna connections. K3 to it or thru the
KPA500? Will there be a special cable like the one for the K3 to
KPA500? Is elecraft offering a wart xfmr for the KAT500? Any minor
details yet to be spoken about?

K9IL

K3, KPA500 & in Aug KAT500 !!!!

I wasn't at Dayton, but you can see the connectors here:

http://www.elecraft.com/KAT500/kat500rear_visalia.jpg

Clearly the "ACC" connection "loops through" the KAT500 to get the
KPA500. This makes sense, as it would allow the tuner to interrupt the
keying line to the amp during tuning, etc.

This part is *speculation* on my part; I imagine that the typical
configuration will be a straight-through DE-15 (as supplied in the
KPAK3AUX kit) between the K3 and KAT500, and another (identical cable)
between the KAT500 and KPA500

Probably K3 -> KAT500 -> KPA500 with 15 pin HD cables (as between K3 and
KPA500) judging from the pictures on the Elecraft news page. It is needed to
interrupt PA PTT during tune up.

Re: KAT 500

In reply to this post by Iain MacDonnell - N6ML-2

This is correct.

However the KAT500 will also work with other radios and amps, so we provide a couple of ways for amp interrupt. With K3 band lines we can bandswitch on receive, otherwise we have to detect band change on Tx, similar to the technique used by the KPA500.

Re: KAT 500

Hi Dick/anyone,

Does that mean that the KAT500 can automatically retune (based on
memory) immediately on band-change, without any RF being transmitted?
That'd be rather cool. If yes, can it also be told that some bands
don't need matching, and so automatically go into bypass for those
bands?

Re: KAT 500

In reply to this post by Iain MacDonnell - N6ML-2

Iain and all,

I actually think there is little difference between "tuning" into an
already resonant load and putting the tuner in bypass. I do not have
the KAT500 to do any testing of that statement, but it is true for all
the other Elecraft tuners I have worked with. To me, leaving the tuner
in all the time just makes sense - just do a TUNE if there is any
question. No need to bypass it except for testing purposes.

In fact, doing a TUNE into that 50 ohm load may be better than bypassing
since any residual reactance will be compensated for.

I do hope Wayne. Eric and Lisa get some sleep on the plane - traveling
East to West makes for a very long day and upset sleep patterns on the
westerly end.

Rest is a huge problem, not to mention on the feet when you are not used to
it. The physical fatigue takes its toll. As a 66 year old runner, I
cannot imagine what just standing in place for a couple of days takes. I
want to get in my 18th marathon next fall and I don't know if I can do it.
The 1/2 marathon was tough enough this year. I used to run them without
thinking. Aging is always a wonderful challenge. As long as the mind
doesn't go first? :-) Then I look at some of my messages and wonder if
mine hasn't already gone. ;-#

Also will the tuner remember tuning values for various band segments?
The 160m and 80m bands are, for example, rather wide, relatively speaking.

Re: KAT 500

But presumably you'd have to transmit some RF for the KAT500 to know
whereabouts in the band you are.... assuming it's using the band-data
from the ACC port... or is there an AUXBUS way for it to get
more-granular QRG data?

Re: KAT 500

It will be on the same 'bus' as the K3/KPA500, so it'll get the info that
way and adapt. For a NON-Elecraft product, YMMV.

Trust them, how many mistakes have they made so far? (Heck they make it
firefighter proof, which is magnitudes harder than idiot proof.)

Now shh, after their Dayton recovery nap, let's let them work so we can play
with the tuner sooner. ;o)
