After one or two panics (mainly caused by not reading my own notes), #5551
lives in its basic form, together with the rework eliminator headers. Its
alignment isn't spot on, but it's not too far out, either! Rx seems very
sensitive but alignment on Tx was not so easy due to power levels being

FYI...
10M was open for a few at the start of NAQP on
Saturday (OK, there was some activity)... it was not
particularly QRP friendly at this QTH (nor were 15 or
20) and this was with a 4 element Steppir at 50'...
That was for stateside contacts, worked UR3HC PY2NY
on 20 with much greater ease.
I don't get on the air much but do enjoy working the major contests. Last
weekend I fired up the K2 and WriteLog and worked the full 10 hours of NAQP.
The K2 did a great job; its little fan fired up on cue during long sessions
of transmitting but otherwise no complaints. WriteLog did its normal
Hi folks,
I want to build a switching power supply for my K2/100
and KAT100 (so, 20+ amps) however I've had trouble
finding a decent switching power supply design that
uses all off-the-shelf components. I know that
there's a design in the ARRL handbook but I'm not
crazy about cooking up

I bought a used K1. It was a cool little rig but to serve as my main
base rig, I wanted more. I wanted better filtering. I wanted full-band
tuning range. I wanted a better AGC. I wanted better receiver
performance. I wanted a better display system. I wanted all the bands.
I bought and
I have an early K2 and an early KX1. My vote for a one-QRP-rig-only is for
the bare-bones K2 for the following reasons:
More power output when you want it. There is a lot of difference between 2W
and 10W but not that much between 10W and 100W (in my opinion)
All bands 80 to 10.
Not that much
Since getting back on the air last fall, and subsequently becoming a
QRPer, I've been constantly perplexed at the continual the bands are
terrible complaints and warnings.
I've had much success and fun working all bands from 160M-10M with 5
watts and a less-than-great antenna, an end-fed
I suppose you really have a reason to want to stay with
WriteLog in spite of how difficult it is and can be
(although it certainly does not sound so in your post!)
so my suggestion may be moot - but - why not try N1MM

When I purchased WriteLog I looked at several other
Don,
You are a genius! Thanks your suggestion worked. I replaced Q9/Q10
with spare 2Ns and the counter started working again. Thank you!

Why no ( real.. ) IF shift ? ( common in all other rigs , even my cheap

Having heard all the pros, and cons, and cons -

they hold their value over years of use - figured
why not buy what the switchers are trying to

Being single conversion may have something to do with it. But I imagine one
could shift the bfo frequency along with the tuning to give the effect of IF
shift, if one had a place to put another knob.

Good evening everyone,
I have just completed RF assembly part II and started the alignment and test
when right off the bat I have a problem.
The 4 MHz Oscillator Calibration step 3 on page 60 states the counter should
show a frequency of 12090 kHz +/- 30 kHz. Well mine reads 12600.
Just a reminder that I'm getting ready to order parts for the 2nd run of
the popular LP-100 kit. As was the case with the first run, this will be
a limited run... first come first served. I plan to order extras, but I
did that the first time and still ran out. The LP-100 is a highly

Two additions to my recent posting based on several replies.
The ARRL composite transmit noise test measurements have been 7.5 dB lower
than reality for many years. This is true for all radios, not just the K2.
My comment about improving the phase noise only applies if the RF board is
Fellow Elecrafters,
I just completed building and installing the KIO2 in K2 S/N 0539. WOW!
Nice accessory kit. It would have been a single evening kit if it were not
for other obligations. Two nights to get it assembled, tested, and
installed? Not bad. I was very pleased to see the
