Hi Guys
Thanks Don, Matt and others answering on my issue.
I have now seen the light. I was deeply in to a engineering mode, where i tried
to do everything according to spec. The spec on the XV144 say
IF input from 28MHz to 30MHz and a output from 144-146 MHz. Then the thing need
to operate
I would love to buy and build a 160-10M K1-9 that did not require module
changes.
Amen to that, so would I !!!

Hi All,
Just a quick question(s)..
I've just finished my K2 and have a few of the options on order, including
the internal battery kit. I was reading the on-line manual and noticed the
info about supply voltage required to charge the battery. This states 14.0
+/- 0.2v at the jack, or 13.7 on the
I am building a K2 and everything has been going fine until the PLL
Reference Oscillator Range test. Pressing the Band+ switch does not change
the PLL reference display (12113). The Band- switch changes the reference
display to 12067. Pressing the Band + switch again displays the PLL
reference
My understanding is that you peak the gain at 145.5 in order to
achieve a reasonable compromise between gain and noise figure at the
low end of 144 ..

Hello everyone.
Thanks for the all of the suggestions (as well as comiserating with me).
Here I thought my lot with all the trees would be a great place to install
several wire antennas (which it is) and never gave it a thought that being in
a hole would present special challenges.
I currently contemplating building a K2 (have a K1 and KX1, K1 is my favorite)
but what I think I really want is a K9! B-)

I obtained a bug speed control device from Frank W7IS, the bug guru,
that he calls an Extendadot. It is a sliding tube that doesn't use
any other weights. You can adjust the speed super fast. You can see

Hello all, can someone tell me if the K160RX and KNB2 modules will interfere
with KPA100 alignment. I am waiting for a toroid core for the KPA100 and have
built the above mentioned modules meanwhile and would like to install them
while waiting on part for KPA100.
Thanks for any info

That 70.4 Volts peak to peak is 12.4 Watts; my Heathkit meter is
reading low.
But probably within its tolerance. 10 watts would be ~63.2 volts peak to
peak, so you're reading less than 1 dB high.
How accurate is the scope? And how much do you need that dB?
Thanks everyone who emailed and replied. I will go ahead and install the
options.

HI
That is also excatly what the userguide are saying. But if it is true what
mentioned in this thread, that the power fall off fast approaching
29MHZ then it is hard to do with the K2, as mentioned i can hardly get 1/3 of
the 1 mW out at the 145.5 on the Xv or 29.5 on the low power

I was thinking about Tom's (K2TA) suggestion about using a K1-9 over a K2.
For battery operation, I might agree. The K1 and the KX1 are more
battery-friendly and really work well.
For portable operation where an AC outlet is available, I think some of the
features of the K2 are so incredibly

I find that I usually have the preamp on for 14 Mhz and higher, while I

One must be careful not to zap the diode in the RF Probe - so measuring
directly across the dummy load is good only up to 20 watts or so. A 'scope
with a proper probe will handle the full 100 watts of the KPA100 easily.
Builders may not have a known good 'scope, and the RF Probe method

Hi
I will throw my two cents worth. I agree with everything Don is saying here
however there are several other ways to get a reasonably accurate power out
measurement on a K2 or K2/100. The simplest and maybe least expensive is the
Elecraft DL1 dummy load kit. This dummy load will handle 20
Hi
Do you have the frequency counter probe connected to the BFO test point. If
you do, does the frequency counter work when you connect it to the 4.000Mhz
oscillator on the control board. If not then you have a problem with the
frequency counter on the control board. Possibly low gain on Q9

I second what Don said about using the Elecraft DL-1 for power measurement.
Recently finished my K2 and found the DL-1 to be invaluable - Everyone
should have one. I must have used it 10 times already, including today when
I installed the 160 m option.
I put the power vs. voltage formula that
OK I am bored and would like to build another K2.
I have built two fully optioned K2's and planned on this one being my
keeper. But I under estimated the enjoyment that goes along with building
one. So its time to buy another K2 and to fund that I need to sell this one.
So the buyer gets one

Ed,
Glad you had nice wx and had an opportunity to put your K2 to the task.
I wonder what radials you were using on the MP-1. I have found in the past
that without 32 1/4 wave (20m) radials the antenna was squat. I've tried using
the MFJ whip, but it is just too much for the tripod
I have to slip a plug in here for my new wattmeter kits... specifically

dummy load, with a variable speed fan option for 100W continuous rating.

Yes, Don converted me a long time ago. I've tried most of the wattmeters for

than the DL-1 and an accurate DMM. Less is more.

the lid. You can see
