Hello
In the past days I have been using my K3 for SW broadcast AM listening.
Marvellous rig for that task, indeed. But I have notice the following:
Some times scaning the bands quickly, I hear a strong pop. The Smeter
goes high and I think I have found a station. I tune backwards and there
I recently purchased the SS-30DV switcher. There are 2
stickers on the outside of the box that say it is an
International Model and you need to change it to 115V AC
input by sliding the selector on the back.The manual (one
sheet) clearly states in the first sentence of a paragraph
titled
YEPI was one of the very first t order the 'International' version when
first released. When I called they did not have stock but expected their first
shipment in the coming week so I odered two (2) of them.
Both units are in daily use and have never let me down...oh no, I should not
have
ooops,
Just for clarifying this, when I say scaning the band I mean turning
the dial knob
Thanks.

Quick Chip or Cash Olson has a removal kit that is extra nice too. He's the one
that has the solder paste, that works so well. Once
you can break or cut the plastic between each pin and desolder or heat
each one out individually. just take your time. Even a Hakko 808 may have
a problem with so many pins.

It won't help you with that task right now since you have already done

For removing the male headers, you can tug on one pin with pliers while

all out.

I am using a PR20 and am able to run my mic gain at about 20.

Thought of something else I ran into last night - I did not have any 820 Ohm
resistors to install on the config connector when wiring up for my Icom HM-7

Should I try to find/make an 820 Ohm resistor or does it matter?

Are you running the mic into the rear panel? If so, check your wiring. I ran
into this problem. You will need either jumper shield and ground or reverse the
two wires as the 1/8 mic jack is mono, not stereo.

Well, since you put this out to public view, I will answer in public.
Please note my admonition to BE CAREFUL, and my suggestion to use a pin
vise, not a powered device. There is no need for a complicated set of
rules of behavior when common sense will do.
If you are so concerned about
Jim,
The rear mic jack itself is stereo, but the signal path is mono - which
means only the tip and shell are connected in the jack (no connection to
the ring).
OTOH, if the mic plug is stereo and connects only to tip and ring
instead of tip and shell, then there will be no connection for one

The problem may be your microphone cable wiring. I will try to cover
the three possible cases I know about for connecting a balanced mic to
an unbalanced input.
The Heil PR20 microphone uses an XLR connector to connect to the mic
cord - two balanced wires on pins 2 and 3 plus the

That microphone has an internal amplifier, and the resistor acts as a
collector load resistor. I would guess that anything from the

At work I get to play with really high end Agilent signal generators and
spectrum analyzers. So my mind started wandering today. Agilent equipment
contain a web server and front panel web page via TCP/IP. What would it do to
the price of a K3 to add that kind of processing power and software?
Tony,
What you say is true, but the fact with many ham radio applications is
that they were designed to run on Windows 3.1 or Windows 98, and have
never been updated to run on later versions of Windows. WinXP *usually*
supports those applications, but the game was changed with Vista and
Don,
It will not give you exactly the K3 front panel display, the Ham Radio
Deluxe can provide you with the K3 function on either a local PC or on a
remote PC.
I know you were asking about native K3 support for that capability, but
if you want the function right now, try HRD, you might like
For a bit of perspective, you can buy a webcam with wifi interface that
provides a built web server for on the order of $100. So in quantity the
additional hardware cost to add it to a K3 would be similar. Add to that
software development for the particular web pages to generate.

One must be cautious with the solder suckers... have done extensive tests with
static discharge from them, and it is well above most active circuit ability to
withstand. In other words... using a solder sucker on today's smt will more
