Tune function seems normal but no output on transmit. Using about 6 watts
setting on tune--external rf ammeter shows expected output. The output bar
graph on the K3 shows the same on transmit as it does on tune, but the
external rf ammeter shows zero--using PTT and a straight key--on transmit.

I am now in the process of setting up the controls for initial SSB tests.
For Xmit Waynes suggestions are great
For Rcv I could use some suggestions ie RF vs AF settings, NB, NR, etc
Thanks in advance

My Driver Q6 has too high voltage on the emitter, 0.42 volts instead of

Lennart,
Where did you find data that indicated the normal voltage on the Q6
emitter was 0.23 to 0.30 volts?
The 0.42 volts that you are measuring is normal and consistent with the
DC Voltage tables.
The base voltage should be close to 0.6 volts higher than the emitter,
so your measured
From what I have read in years past, I agree locking the two

to be sure of this, though - having each radio in a separate earphone
may be all one needs unless beam-forming is a goal. In time we will
see how the subreceiver is

DON'T DO IT! The SB200 applies Minus 140 volts or so to the relay control
jack and the K3 can not control it. You could damage the K3.

If your SB-200 has not been modified, its relay voltage is negative, and
THAT will cause problems.
The HEXFET in the K3 will take up to 200 volts, but that must be a

And the answer is?? I've been led to believe this isn't such a good
idea, and that you should use one of those amp keying kits that the Heathkit
Shop sells. I've got an old SB-200 sitting around here, but I've been
afraid to try it!

I can thoroughly recommend Harbach Electronics' SK-201 keying kit for the
SB200.
Easy to fit and doesn't break the bank. Reduces keying requirements
Aha!
Many thanks for the pic Patrick, I have a feeling I've seen that somewhere

Better yet - If you can find a MFJ / Ameritron ARB-702 before you leave
http://www.ameritron.com/Product.php?productid=ARB-702
We've used them with SB200 and FL2100 amps on a couple trips to FP and
they are great and pretty much bullet proof.

Hi Everyone,
My K3 (#371) has the KRX3 installed and is sharing the same antenna with
the primary receiver. Since it was installed I have noticed that the
sub-Rx audio volume is down compared to the main receiver requiring my
to run the AF for the sub-RX about 20% higher than the main
Since installing Beta 2.67 and using the new audio balance feature with
the sub receiver audio control, I notice that I cannot get a balance
between the two receivers without running the sub-RX audio control at the
2-3 o'clock position.
Same here, but it was more like the 1-2 o'clock

Hi, Has anyone else had big difficulty getting the front panel connector jacks
to match up with the plugs on the RF board when installing the front panel?
The problem appears to be the plug behind the mic connector (p50) not wanting
to mate.
Pins appear to be straight and equally spaced like
I installed this Harbach kit on two SB-200s I have. It takes very little
time and the peace of mind is worth it. You might as well install the
soft-start and soft-key mods at the same time - they go roughly into the
same place on the underside of the SB-200.
Pictures:
The connectors are very tight, Mike, especially when mating them for the
first time.
Are the connectors on the bottom of the RF board mating properly with the
connectors on the front panel assembly (not offset to one side or the other
by a pin)? They're shown in Fig 59 of the Rev E assy
I have had the clock displayed on my K3 since day one. Today I noticed that
tapping DISP only rotates between the VFO B Frequency readout and the

Marinos,
Marinos,
Based on your voltage readings at Q18, the VCO is not actually
oscillating (indicated by a lack of negative voltage at the gate). I
don't know why you have any frequency reading at TP1, but I would tend
to disregard it for the moment.
The first thing to check is the
Disregard. I found that you tap DISP then rotate VFO B to select what is
displayed. Apparently it only rotates between two selections.

Something seems to have crept into the last firmware build that I don't

When I turn the rig on there is a momentary loud blast from the speakers. It

I had a to replace a final transistor earlier this year, and after that I
checked most of the compeonents and voltages around Q6-8. That is when I
noticed that the Q6 had an unhealthy temperature. R50 looked normal and
measured 1.5 ohms. The Q6 got glowing hot and the emitter voltage kept
rising.
Forexample: A very simple fix is to use a OptoMOS relay. The
LCA110 from CLARE can key 350V 120 mA, cost seems to be a
little over 2 USD.
