I have worked on thousands of these and I *never* pull the side panel to
take out the KAT3 (or KANT3) boards.
Too difficult if there is a sub-receiver and too likely to introduce a
problem (broken regulator(s), miss-pinned sub receiver) from removing
all that.
Take off top cover and take out
Because the KAT3A was marketed both as a replacement for the KAT3 and as
a component of new K3s rigs, its installation instructions show how to
remove the previous antenna tuner card, if necessary.

Can anyone tell me the secret to pulling the KAT3A tuner card out of a
K3? I changed it out once for the newest version but forgot how I did it. Part
of th chassis frame stops the board from being pulled out.

For station use at home I could get by without. But my radios are used for many
club/portable events and antennas are often not optimal. So a ATU is helpful.
And I figure if I ever want to sell it it might bring either higher price or
quicker sale.

It was a $400 option and unnecessary with resonant antennas. I have three
Elecraft K3S's and none of them have KAT3A tuners.

Why not try it.
The KAT3(a) can tune many a strange antenna.
It seems so easy to hook up the antenna and tap the button to see if it works
instead of typing a query here and getting many responses. A lot of which will
suggest “Try it and see. “
Good luck.

If I had a problem with a KAT3, the first thing I would check would be
the relays.
But where is the LP100 connected? It must be AFTER the KAT3, so a
problem in the KAT3 would not change the SWR indicated on the LP100 (or
the P3 for that matter).
Maybe you had a cable, connector, or antenna
I have been having unusual transmit issues
with 160M, SWR issues I have long thought

for the P3 but no output shown on the P3

Joseph,
Get yourself a *new* #1 phillips screwdriver (if your screwdriver tip
looks shiny, it is worn, throw it away). If you are trying to use a #2
(the most common phillips), then get a #1. You may be wise to replace
the stripped screws. Consider the Stainless Steel screw kit from
KAT3A and KIO3B installed! Had a scare as I couldn't remove the bottom
center screw on the right side panel, it started stripping. I had this
issue on one of the front panel screws about a year ago when I was trying
to replace my VFO B encoder. I was able to get the KAT3A installed without
I bet the KEY macro in N1MM+ would work. Purely speculation on my part since I
haven't tried it but it works fine for CW.

Help:
There is no access to FSK-D using CAT commands other than those
supplying ASCII strings.
FSK-D can transmit using paddle (not straight key) input, ASCII text,
the FSK pin on the ACC connector (with a one transistor keying
interface) or from the Terminal screen of K3 Utility.
I do not know
I've attempted to configure MMTTY to run FSK with my K3S. Conclusion is that a
Terminal unit will be required. Using AFSK is easy and I don't find any
disadvantages. No additional hardware required.

None that I know of. FSK is not normally a CAT control nor is it done with
“handshake” signals on standard serial port. It is passed on the TX line of a
RS-232 serial connection to a discrete pin on a radio for FSK signaling. My K3
has such a pin on the Acc2 connector on the rear of the radio.
I don't think there is a lot of software that supports sending the FSK with
CAT commands. Does anyone know of any others?

A very good idea Gordon. I do that with cocoaModem, which allows
me to decode the second receiver as well, allowing Single
Operator Two Receiver contesting. fldigi is also a possibility.

Using the CAT interface this way is great. BUT you loose some decoding
ability. I run a K3 in RTTY contests, TX is FSK RX is 3 decoders, the
K3 built in, mmtty and 2tone. usually 2tone beats the other 2, with
mmtty sometimes winning. The K3 decoder misses the most. You might

The KAT3A fits in any K3S, with or without the KPA3.

KAT3A has a bypass relay when the tuner is not in use.
KBPF3A changes the bandpass filter for 0.5 - 2.0 MHz "band" to move
the lower cutoff from 500 KHz to 100 KHz.

Is the K3S ATU different tan the old K3ATU installed in the K3?
I was told that if I want to upgrade a K3 with general coverage to a similar
K3S I need to change:
KAT3A
KBPF3A
KSYN3AUPG
KXV3B
But my question s what is different in KAT3 and KBPF3A that I need to change
them
I am the proud owner of K3/10 #8972, recently upgraded with the KPA3.
Two questions:
Has the KPA3 been upgraded to new PA finals? It would appear so with a
Mitsubishi device rather than the Toshiba.
Is the KAT3A compatible with the K3 as that is my next upgrade?
