Good Evening,

   Another chilly, wet week.  Spring progresses slowly up here. The 
rain has made it very green.  Moss really does grow on the north sides 
of trees in Oregon.  It grows on most of the rest of the tree too.  But 
circular objects only have two sides: in and out.  Propagation remains 
weak.  The sun tossed a CME, it missed. Bands should be fairly quiet, 
which can help.  Maybe QSB will be helpful and pull you up for a moment.


   If you wish to exercise your gray cells to examine other circular 
systems:

The ship was the pride of the American side
Coming back from some mill in Wisconsin
As the big freighters go, it was bigger than most
With a crew and good captain well seasoned
Concluding some terms with a couple of steel firms
When they left fully loaded for Cleveland
Then later that night when the ship's bell rang
Could it be the north wind they'd been feelin'?

The wind in the wires made a tattle-tale sound
When the wave broke over the railing
And every man knew, as the captain did too
'Twas the witch of November come stealin'
The dawn came late and the breakfast had to wait
When the gales of November came slashin'
When afternoon came it was freezing rain
In the face of a hurricane west wind

I was tempted to reply to the original post but it was not clear to me who

Hopefully at least some of those who replied had either played cricket or had

Art,

Don, W3FPR used to do much of this work on K2 transceivers, but he has
retired from that role.  Dave, W8FGU has assumed Don's role.  Alan, W3DVX
also provides such services.  Both have posted periodically to this forum. 
There may be others who are experienced K2 upgraders, but these are the
folks that come to mind.

Re: [Elecraft] KSB2 problems in K2 transceiver

[Don Wilhelm]

Mark,

When you have the problem, look at the voltage at P1 pin 6 (that is 
VRFDET signal)?

If that is high, the MCU will limit power drastically.

Make sure Q1 is properly oriented.  If that does not help, try a mod to 
the KSB2 - reduce R9 to 1.5k and cut the trace between P1 pin 6 and the 
base of Q1 (on the top of the board) and insert a 1k resistor across the 
trace cut.

That will calm ALC problems with the KSB2, and otherwise will do no harm.

73,
Don W3FPR

All voltages looked slightly low but ball park on the KSB2 board except for

I have removed the KSB2 and full CW power output can now be achieved which
is a relief.

I will examine everything under a microscope again but has anyone any

Re: [Elecraft] K3 (S) Weird Main RX issue

[Bob Wilson, N6TV]

Does rotating the MAIN RF GAIN knob back and forth make any difference?  Or
tapping the ANT or RX ANT buttons a lot to exercise the antenna relays?

I assume both receivers are listening to ANT1, and nothing is connected to
AUX RF or RX ANT.

What happens if you move the coax to ANT2?

I think you question has been answered but just for clarification -  The KAT500 
needs to know frequency not band.  Even if the KPA500 was sending band info to 
the KAT500 it wouldn't be much use because KAT500 antenna and tuning solution 
selection is based on frequency not band.

Having the KPA500 and KAT500 tune before transmit requires something to send TX 
band data to KPA500 and TX frequency data to KAT500.   Following Kenwood FA is 
a weak (in my opinion hopelessly unsatisfactory) solution since split operation 
usually has VFO B as the TX VFO.

Elecraft has been asked to revise the KAT500 firmware so it properly extracts 
TX frequency from IF, FA, and FB just like KPA500 and KPA1500 do.  I don't know 
when/if that update will be available.

Re: [Elecraft] KPA500-KAT500 tuning settings

[Bob Wilson, N6TV]

Steef,

See this recent post for explanation:
http://mailman.qth.net/pipermail/elecraft/2021-April/284736.html.

The KAT500 can auto-track any Kenwood or Kenwood-compatible rig that
outputs frequency data in the format:  "FA00014025000;".  Connect the RS232
RXD line (Pin 2) of the Kenwood rig to the TXD line (tip) of KAT500 PC DATA
connector, with no connection on ring.  You have to use the BR; command to
set the baud rate of the KAT500 PC DATA jack to match the rig's RS232 baud
rate.

You can also uise a program like N4PY Pegasus Plus
 to keep the KAT500 / KPA500 in
sync. with the rig.

The S-BOX-USB provides either capability using standard commercial stereo
and serial cables, with parallel wiring to all logging programs and the
KPA500 XCVR SERIAL connector, so no splitters or custom cables are
required.  If you're using a TS-590S with a working USB port, you can
connect the computer to the USB port and connect both the KPA500 / KAT500
to the TS-590S COM port with such wiring (only wired RXD in parallel, never
TXD).

Modern Yaesu rigs do not output enough digits of information in the FA
command output (they drop most of the leading zeroes).  The KPA1500
firmware can handle the Yaesu format of FA frequency data to auto-track,
but the KPA500 and KAT500 cannot, though they could potentially be updated
to do that.

Bob, N6TV

Re: [Elecraft] KSB2 problems in K2 transceiver

[Mike K8CN]

Mark,

Pin 5 of U2 provides ALC threshold voltage to the emitter of Q1 on the KSB2
board.  The 5.89 V you measured on Pin 5 suggests that the DAC input
register B didn't properly load the data word from the MCU.  I would check
the solder joints on all U2 pins and Pins 14, 16 and 17 of the MCU socket.  

73,
Mike, K8CN

Re: [Elecraft] KPA500-KAT500 tuning settings

[Alan - G4GNX]

AFAICR The KAT500 follows the K3, not the KPA500, as long as the Aux-bus 
cable is connected. I can certainly hear the relays click on the KAT500 
when I tune the K3 across a frequency threshold point.

Subject: [Elecraft] KPA500-KAT500 tuning settings


Hi,

if I switch the KPA500 with the band buttons to another band I would expect the 
KAT500 to follow the last tune settings on the new band. However this is not 
the case, the tuner switches to the new band settings only when HF goes 
through. The 15-p cable is connected and there is no K3 connected.
Is there a menu setting to let the KAT500 follow the KPA500?

[Elecraft] K3 (S) Weird Main RX issue

[Udo Langenohl - DK5YA]

Gentleman,

I have a problem with the main receiver on one of my K3s. The main 
receiver is between 6 and 8dB worse than the second receiver. The stupid 
thing about it: it is not always like that, but the poor sensitivity 
comes sometimes creeping or sometimes suddenly. It seems to have 
something to do with the transmit / receive switching. I checked this 
very carefully with an HP8664A signal generator and a spectrum analyzer. 
Sometimes both receivers are exactly the same, then the main receiver 
slowly gets worse and worse (within a minute the amplification drops by 
6-8dB) sometimes it happens immediately after switching from RX to TX 
and back. Then it happens that after switching from RX to TX and back 
again, both receivers are the same again. It can also happen that the 
main receiver is initially 8dB worse than the second receiver, but 
without RX / TX switching the missing 6-8dB are suddenly there again - 
in the middle of receiving mode, without switching. So it's intermittent 
and it drives me crazy not to find out what's going on. Is that another 
bad pin diode somewhere in the main receiver and if so: which one? Maybe 
someone has an idea? Help is very much appreciated.


This is a K3 #56xx with all features and all upgrades so its more or 
less a K3S rather than an K3.


73 Udo, DK5YA
