It was a pleasure meeting those with K2's and those either building or
contemplating
Sounds good to me...

Might I suggest something less commercial... haul a

Hi Bill:
Hello! I am curious about where I could buy the blank circuit board
for the thru-hole version of the visible CW tuning indicator. Does
Far Circuits carry them?
I have a thru-hole board design for this circuit. It's somewhat larger than
the SMD version, but works just as well.

Hi Guys, I have moved my shack to an upstairs bedroom and consequentially I
will need to feed my 130 feet wire at the end rather than at the centre (it
was a dipole fed with coax). I want to work 80/40/20m. I have made some
open wire feeder (about 15 feet) to get me from the chimney to the
Q #1: why is 500-600 hz offset reccommended by the manual.? What's wrong with,
say, 750 hz?
Q #2: What is, or who are the FISTS ops, and what freqs? Is this a joke?

You
George,
A#1: There is nothing wrong with 750 Hz if that suits your ears better.
Most of us feel that is too high for comfort. In fact, that pitch was
'forced' on us by earlier transceivers that tried to use the same BFO
crystal for both SSB and CW. Thankfully, the K2 and K1 give us a choice.
Martin,
To be a Zepp antenna, the parallel feedline would have to be an odd multiple
of a quarter wavelength, and that quarter wave a;so serves in place of a
'counterpoise wire', so your 15 feet is a futile effort in that regard.
Just as well to use a single wire for the 15 feet to the end (and
Hi Matt,
you can find a DOS program called 'atten_22.zip' by OH0NC at
http://www.rmham.org/files/misc/index.html.
This enables you to calculate a Pi or T pad for a given input and output
impedance. Note that if the input to output transforming does not correspond
to your specified attenuation,

Hi All,
I have an 100 Mhz BK Precision Oscilloscope, model 2190A,
for sale, that I no longer use.
It is a dual channel analog scope (with a third channel for
external triggering if needed), and in excellent physical and
100% electronic condition.
The specifications are almost identical to the

You could consider making a 5 dB pad that also
matchs from 50 to 75 ohms. 5 dB would not
sacrifice too much sensitivity, and it would be
very broadband, being nothing but three resisters.
Good luck and 73

The key to setting these filters is to understand what is being used to
generate the RTTY or AFSK tones. In my case, a KAM, as I indicated
initially, was used for RTTY. This means that the KAM must be fed 2125Hz
tones from the K2, then shift down if RTTY normal and up if RTTY reverse by

No, I had expressed two different opinions. First, I was responding to the
question of whether a 3 ele beam was better for QRP than a vertical. And in
an aside, I had remembered that mc was looking for a SMALL antenna for use
at sea. Obviously, a yagi isn't a small antenna at HF. I was remarking

Hi,

Mike,
Unless you are dead set on doing that in a hardware interface, try Ham Radio

into them (or can be customized for that function).
If you wish to create a hardware interface, I might suggest that the easiest
path is
Paul,
With PSK31 (or any of the soundcard digital modes), the normal up to 30 Hz
shift of tones when switching from filter to filter can be bothersome. This
small shift is inherent in the digital control of the K2 VFO and BFO
frequencies, and can be expected.
The 'cure' is not in the K2, but in
I have read the KAT100/KPA100 description by KK7P, as well as various
reflector postings. However, the KK7P description covered several

including operating a K2 with only the KPA100 in an EC-2, as well as with a
KAT100 KPA100 integrated in the EC-2. Thus, I'm still not clear

I never call CQ FISTS unless it's a FISTS contest; and that may be

You must be a subscriber to post to the list.
Hi Mark,
It best to join FISTS and get a membership number. The number is good for
life even if you subscribe for only a year. This way you can CQ with anyone
nearby on frequency. 14.058 and 14.060 are only guidelines. Activity can
be plus or minus due to propagation, RFI, ongoing QSOs, etc.

Don is right, about needing 1/4 wave of feedline (or an odd multiple
thereof) so it will act as a transmission line transformer to convert a high
impedance at the antenna to a low impedance at the rig. But that also
requires a high impedance feed at the antenna. That is, an antenna 1/2 wave
