Rick;
I recently completed K1 2136 and went with the 120pF VFO capacitor. This
gave me a tuning range of approx 178KHz and 15KHz/rev which is just a
"little" touchy but not difficult. It depends on how stable your fingers
are when tuning. I may try 100pF to make it just a bit easier.
Russ,
For the rope, try qualitynylonrope.com I'm not sure if they have grey or brown
but I bought a 500ft spool of 3/16" black polyester for $42. AND they have
free shipping for orders over $25. Russ, N3CO

What power are you running? Try an experiment by turning the power level down
or up thereby switching between the LPA and the KPA3 to see if this changes the
intermod level. This may narrow it down to the TR switch. I have had a
similar problem with intermods between a couple of local AM stat
I have K3 S/N 732 and use a $2 electret computer mic I bought at a yard sale.
They had a white one that was only a $1 but I chose to go the more expensive
route and buy the $2 black one to match the K3. My settings are -16db up to
400 Hz, 0dB at 800-1600 Hz, and +16 dB at 2400 up and I get go
Do you have the new KSYN3A? I just experienced a similar problem but tapping
on the case didn't solve anything. Elecraft support determined I have a bad

Will my old K3 #732 work with my Vibroplex or will I need the K3s? I want to
make sure I have all the latest. Or I guess I could just use my HT-32As. Russ,

The Koss SB45 has been working great for me and cheaper than the CM500. You
can get them on Amazon for less than $30. Russ, N3CO

In this recent discussion here on K3 QRM from strong local broadcast stations,
W4TV brought up the noise generated in the T/R switching diodes. In doing
some experimentation with a bandpass flter in the loop between the RX antenna
"out" and "in" on the KXV3A I have discovered something which

I never operate 10M but just checked my K2 with the KPA100 and found the
same thing with a strong birdie at around 28262. The weird thing is that
when I turned off the KPA100 (reducing power below 10W) the birdie at 28262
shifted up about 1kc and the birdie at 28019 shifted down about 500c.
Russ,

The DIP version of the SSM2165 is no longer available from ADI.

56" for the original cable is quite long. What gauge cable are you using?

You brought up a good point that I had not thought of and that is the voltage

After reading your numbers here I was curious since my K3 is the same vintage

Hi Ben:
You had me curious with your request. I started to check my KBPF3 (modified to
the "A") and noticed something that now bothers me. I tried going down from
160M and it appears that the switch over to the AM broadcast band occurs
precisely at 1700,000 Kc. When I tune to 1.69 the
Hi Knut:
I couldn't tell you if this is a new problem as I didn't notice anything amiss
until I started checking switchover frequencies to answer W4SC's question. I
verified that the KBPF3 is enabled in the config menu. I bought the used
KBPF3 about 4-5 years ago from another ham and don't r
Brian,Thanks for your information which got me thinking again about my
situation. I went back and set the config for the KBPF3 to "not inSt" and
found no difference at the signal levels at the switchover at 1700 Kc.
Toggling back and forth between "not inSt" and "nor" I verified that there i
Thanks Ben, I didn't think of that. Now when the KBPF3 is not inst There is
no difference in signal level when transitioning from 1.700 to 1.69. And
when I set the KBPF3 to nor (and reboot) there is a definite drop of 5-7 S
units at the 1.700 transition point and also at the the 2.11 to 2
Just an FYI, I found out what the problem is with my modified KBPF3. I
removed the added caps and signal levels returned to somewhat normal levels.
Adding a cap to C2 didn't make sense and attenuated the signals. But Fig. 14
shows adding a cap to C4. Apparently the ham I bought this from us
