Perhaps one of the design wizards that reads this list could come up with
something like this http://www.ussc.com/~turner/syn_blank.html adapted for HF
and the K2.
My guess is that noise blanker effectiveness is directly related to the
characteristics of the noise. One blanker's design specs ar
Hello,
Some dreams on improvements for the KX1 for back packing/mountain topping.
The case edges could use a ruggedized plastic surface. I find myself
often operating above the tree line on granite blocks and rarely a flat
surface. The case edges are getting nicked. Anyone make a plastic case
Good Evening,
Twenty meters, as usual, was quieter than forty. Folks to the East of
me complained a little of QSB while I had QSB on the folks West of me.
But, all in all, the signals were quite good. Only N8XE popped up, got
recognized, and was gone once again.

John,
IMHO, believe the DL-1/DMM combination first. If you have an opportunity,
check the DL-1 with an antenna analyzer to see how close it actually is to
50 ohms non-reactive - that should increase your confidence level.
The WM-2 when properly calibrated is speced for 5% of full scale, so if yo
Not NICER, but different. I stuck mine in the traditional Altoids tin. I had
to replace the PC-mounted BNC with a chassis mount type. If you don't, the
hole for the BNC impinges on the cover and you have to "clearance" the cover
which looks even more mickeymouse than putting a BL-1 in an Altoids ti
I assume you are using the DL-1 as the load for all three tests, in
which case I would have to go with the DL-1 plus DMM. The impedance
error should be less than 5%, and the voltage measurement error less
than that.

Just finished building KX-1 #1207 with 30m board and ATU. Nice little rig!
After adjusting C9 on the KXAT-1 per the manual, I decided to compare the
power output measurements obtained via the internal power sensor, a DL-1
dummy load + DMM, and using my OHR WM-2 QRP wattmeter. BTW, the supply
Hello to all.
I haven't seen much concerning an enclosure for the BL-1. Mine is shared
amongst several
rigs. To me it looks a bit frail when I mount it to the ant connector
with a BNC coupler, kinda just
hanging there with some stress on the connector.
So I found in Radio Shack a Project Encl

Zac,
Check the voltage on U6 pin 17 while in the menu (at a time you say you can
hear audio). If it goes to a higher voltage, then suspect the MCU itself,
but if it stays at 0 volts, look for a short on the '/MUTE' signal line. I
believe the only parts involved in this signal line are U6 pin 17,

If you want to experiment, I would suggest the K2 rather than the K1 - the
K1 being more compact is more difficult to find 'handles' to the parts you
want to experiment with while the basic K2 has lots of 'wide open space' (if

Joe,
I do agree with you for the full 100%!
I do have here a Ten-Tec Paragon. The same waste of money (the NB of

It would be of great help to may of us to redesign it or at least make an

I have both a K1 and K2, though I have very little experience with the K2,
having just finished it in the last couple weeks.
One of the issues I'd be thinking about is the difficulty of swapping filter
boards. If you buy a 4-band K1 you can't get 80M or 160M on it. So if you

Hello,
After reading thru the troubleshooting section of the manual, I reheated the
solder joints at Q6 & Q7. Unfortunately, nothing changed. It is as if the K2 is
always muted, except when in menu mode after "Atu" is selected. I read thru
some of the previous threads on the list related to K2s
I have both a K1 and a K2, David. Since you already have a KX1, the K1 is
only going to be another answer to the same question. They are different,
but their missions overlap. The K1 is a station rig that is at home in the
field. The KX1 is a field rig that works at home. I don't see any real

Congratulations John. Building it will be fun and operating it will be

If anyone is interested in buying a fully built and tested K2 I have one
posted on the Ham Radio Market Website. You may be able to bargain with
LA2CFAdepending on how much
he is willing to let it go for. Asking prices are listed.

I have built 98 K2's to date. Let me build your radio. My prices are
reasonable, and you receive a completed, tested k2 ready for fun.

I'm on page 64 of the K2 manual. No matter what frequency I tune, I hear

In my ignorance, I thought I'd just buy four BNC plugs, some RG58 and

Hi everyone,
Last night, I finished building and testing the KPA100. Today, I made several
QRO contacts and got good reports on the audio from the KSB2 and the Heil desk
mike.
K2 # 4970 also has the noise blanker, DSP filter and 160 meters installed. The
DSP filter is incredible. Signals se
I too have found the KNB2 lacking in most real world noise situations. I
even built a second one. Yes, when you scratch Q22 it works. However, that
is irrelevant. Most impulse noise on the air in my area slips right
through. Compared to the FT1000 and FT736R it is a poor third. Time to
redesign
Thanks for your technical information Geoff.
