AUX not available for PC when using KAT100?

I'm thinking about purchasing KPA100 and KAT100 for my K2.

Is the following true? KAT100 occupies AUX port of KPA100
and makes controlling K2 from PC (MixW etc) impossible.

No, not true. From the plug in the AUX port in the KPA100 come two cables,
one to your computer serial port and one as control to the KAT 100.

Re: AUX not available for PC when using KAT100?

Do the kits come with everything to make a Y cable or do you need to
order extra?

Re: AUX not available for PC when using KAT100?

Dave and all,

OK, the way it works is: The KPA100 (or KIO2) comes with a cable and 2
connectors (and backshells) to build the cable to connect to the
computer. The KAT100 kit contains a length of cable and one connector
to go onto the KAT100 end.

The pins for the cable to the computer are different than the pins used
between the KPA100 and the KAT100 (this is NOT an "RS232 cable" - the K2
is marked 'AUX I/O' and it means just that, DO NOT PLUG AN RS232 SERIAL
CABLE ONTO THE K2).

If you have both kits, you can build both ends of the cable at the same
time - see the illustration in the KAT100 manual for the entire cable
assembly.

Yes

Be sure to read [and understand] the warnings about the IO connector.
It is **NOT** a standard RS-232 serial port!

Backward CW?

In reply to this post by Don Wilhelm-3

Well here comes the probably-stupid-question-of-the-day:

After nearly 90 minutes on the NAQCC sprint last night - sending and
answering dozens of calls, some from pretty strong signals - without a
single contact, I gotta wonder if the problem is on my end.

How can I tell if my carrier is on the correct side of zero-beat?

Then how do I fix it?

Have I even asked the right question?

Thanks es 73,

Tom, [hidden email]

Re: Backward CW?

Tom,

I believe you asked the right question.

Assuming that your filters are set so you do hear a signal at the
sidetone pitch on both CW and CWr, do the following - (if not, you
should do the whole filter setting task - see the 3rd paragraph below).

To see if your filters are set to the correct side of the carrier, you
should enter the menu for CAL FIL, then tap the BAND- button. You can
see the DAC values for both CW and CWr - for each of the 4 filters, the
DAC value for CW should be lower than the one for CWr. If that is true,
then you have the BFOs set to the correct sideband. If you have the
counter probe installed in TP2, you can read the actual BFO frequency by
tapping the DISPLAY button.

If you find the BFOs on the wrong sideband, you must open the K2 and
connect the K2 frequency counter probe to TP2 to change the settings.
The K2 manual contains information for entering the menu and the related
'button-tap/hold' sequences to get to the CAL FIL menu - if you are not
familiar with that part of the task, please review that portion of the
manual first (if you built your K2 you already know how to do it).

Should your filters/BFOs need changed, I recommend you use Spectrogram
to give a visual display of your filter passbands. Spectrogram version
5 (the last freeware version) and how to use it info is available at Tom
Hammond's website www.n0ss.net and if you want to accomplish a full K2
dial calibration job while you are in the process, check out my website
http://w3fpr.qrpradio.com article on K2 Dial Calibration. If you do not
wish to do the full task, you can simply set the filters to the settings
indicated in the KSB2 manual (if you have that option installed) or in
the K2 manual if the KSB2 is absent.

It is not difficult, I am just trying to be complete here with some
consideration for brevity.

RE: Backward CW?

Hi Don, Mike, et al.

Thanks for the advice.

Using spectrogram I checked filter alignment for all filters and then
reworked them all. Now, the DAC for each of the filters in CW is BELOW the
center frequency and the DAC for each of the filters in CWR is ABOVE the
center frequency.

However, when I tune identical signals on my TS-820S (factory calibrated a
couple of years ago) all the signals are about 1 KHz higher on the 820.

Before I crack the case and see if I put the board in backwards, or
something, would you please comment on the following:

As I tune up the band (to higher frequencies) on 40, the pitch of the
received signal goes up. On the 820, the pitch goes DOWN as I tune up the
band.

Frustrated in VA (but it IS Miller-time)

Tom, kj3d

This info won't be of help, but for *any* sideband receiver:

If the received signal's pitch INcreases when tuning UPward, the receiver is in LSB mode.

If the received signal's pitch DEcreases when tuning UPward, the receiver is in USB mode.

Your K2 receiver is functioning in LSB mode on CW, and your TS-820 is functioning on USB mode on CW.

Re: Backward CW?

In reply to this post by KJ3D-2

Tom,

Since I don't know about the dial calibration accuracy on your TS-820S
even though it may have been factory calibrated, and I haven't
investigated the high side/low side injection scheme for its mixer and
product detector, I cannot comment on the dial reading comparison. I do
ask one question for you to investigate for a possible answer - does the
820 display the frequency the receiver is actually tuned to or does it
compensate for a CW offset in the dial reading. The K2 will always
indicate the carrier frequency, and in CW the dial will read correctly
when a carrier is received at the same pitch as the sidetone.

The pitch change vs. dial frequency change - if you switch the K2 to
CWr, you will find the pitch of the note will decrease as the frequency
increases, just like your TS-820. It is just a matter of which side of
the IF signal the BFO is positioned (and also a result of the VCO
injection, high vs. low).

If you want a valid check on the K2 dial accuracy, tune a WWV carrier so
that the pitch (during silent periods) is the same as your sidetone
pitch - the K2 dial should then read 10000.00 MHz (or 15000.00) or very
close to that value (within 30 Hz). If it does not, you can do the dial
calibration procedure indicated on my website http://w3fpr.qrpradio.com
- remember you must complete ALL the steps before you can evaluate the
correctness of the result.

FWIW: I've found that the waterfall display in MMTTY or MixW is easier
for me when doing the CAL FIL. No markers, but the display is much
crisper for me, and the frequency calibration marks at the top pretty
much make up for the lack of markers.

Re: Backward CW?

Fred,

Yes, that works, and Spectrogram has a waterfall type display too. I
find that the spectral display is much easier for my eyes to discern
than the subtle shift of colors on a waterfall display - YMMV - Use
whatever works best for you.

Backward CW - Redux

In reply to this post by KJ3D-2

To all who responded - a resounding THANK YOU.

I seem to be OK now.

When I first set out to work on the CW filters, I found half of them on the
wrong side. Before starting on them, I decided to redo my SSB filters
(which were OK) and managed to screw them up. Then, after setting up the CW
filters, they were ALL wrong.

After finding and fixing the SSB then redoing the CW, all seems well. In
fact I just worked W9ZN and apparently he could actually hear me.

Anyway, things seem to be working ok.

Once again, the responsiveness of this group has validated my decision to
build 4991.
