I am still in the market for a K2, I've decided to get just the qrp version
and not the K2/100. My FT-1000D will handle those chores. I'd like the K2
to have at least the following options
160
SSB
Tuner
Battery
AF filter
Would like a fairly late serial number, or one that has been upgraded. If
For those who might be interested I have put details of an additional receiver
filter for the K2 onto my web site - http://homepages.nildram.co.uk/~baker/

Stewart,
WOW --
The plots look fantastic. I suspect that the large ground plane on the KSB2
board helps a lot too. I may be trying to convince Elecraft to sell me a
couple bare KSB2 boards and try it here myself.
I would be interested in seeing some plots of the CW filters with this

No. The oscillation you are checking for would be in the normal a-c range of

Hello Fellow Elecraft Enthusiasts,
Last night the final assembly on K2 #4661 was completed. This morning I
made my first contacts on using 2W, 5W, and 10W with CW.
It's great to have one of these sitting in my shack. I've wanted to
build one of these rigs for a few years. I admit that I was
I have built to the VCO test on p. 60 of my manual. I am supposed to get a
frequency counter reading of 8 to 10 MHz range. I read 12424.11.
I have not been able to find where I need to go in the Troubleshooting section
to figure out what I've done wrong.
There are a couple of things I'm not

Had my trusty DRAKE TR-7/R7A, 1978 THE DRAKE 7 LINE WAS TOPS The combo
transceiver with the rare R7A weighed in about $4000. Everything was optional.
I did some side by side performnce checks. The sensitivity issue is very
complicated.
The tR-7 does not use a pre-amp at all before the
First question - are you getting Hi Cur messages when the K2 is connected to
a dummy load? If not, all is well and the 'fault' is that the antenna
connected to the K2 must have an input impedance of close to 50 ohms. To
use the antennas you described, a tuner is a must. Do not try transmitting
Well after about 5-6 months of building, K2 # 4429 was used for its first on
the air contact today.
I had also only had 5 cw contacts ever before this, all around 10 years ago, so
it was pretty well new for me too. All went well. I didn't get perfect copy,
but I was much more relaxed than I
Jason: You've already gotten some good comments. Don is right to ask
if you're getting problems with the dummy load. The fact that you are
bouncing your tv around sounds like you've got a somewhat makeshift,
and possibly unstable, antenna. That could be causing the problem.
One thing that
Interesting comparisons!
After the K2/100 combo was released, I always considered the K2 one of the
big boys - just not one of the really, really expensive boys Hi!
The K2 is at its best with the pre-amp off below 15 MHz unless it's hooked
to a really low-gain antenna like a short whip. The K2
That's $4000 in 1978 dollars... probably less than a K2 in today's
dollars. I wish I still had my TR7... in retrospect, it was probably my
favorite rig ever, and that includes a lot of rigs from Collins, ICOM,
Kenwood, TenTec, etc. It was also one of the few I've had (besides the
K2) that you
Sure been quiet here in NY...
Worked abt 6 cw stations ( all Elecraft users ),
But no SSB??? been hunting without luck.

To All,
Tony Wells, G7IGG [EMAIL PROTECTED] and I are testing an EH
antenna vs a normal 1/4 wave dipole and we need some signal reports.
The test is using my K2 and Tony's Beacon Monster software. I am operating
a manually controlled beacon on 14.102 MHz. The software times the beacon
Hi All,
What are the most popular bands for slow QSO's, Would I be correct in
assuming 80 and 40 meters ? I'm a newbie with CW so I go very slow and have
just made contacts ( a different radio) on them.
The used radio I purchased has the 4 band board install, but has extra 2
band board is
i was out hiking in the Florissant Fossil Beds National Monument today for
the EQP.
Started at 1900Z and worked 25 Q's on 20M and 1 on 40M.
i was using my KX1 #292 (3W) with a 10 foot whip (no top hat) and a 13 foot
drag wire, pedestrian mobile.
The trail was 30% deep snow and then ice and mud,
Paul is a walking advertisement for the KX1LITERALLY. I heard him all
over 20m for the 3 hours that I operated and he was ALWAYS one of the
strongest QRP stations here in So Cal...559 to 599. Amazing! A fine op, too.
Thanks for the QSO, Paul.

Unless I am misunderstanding what you mean, I think you went the wrong
way with the dollars...$4000 in 1978 is about $12,000 today.
Thanks for the info.
To clarify some things:
My indoor random wire antenna is _very_ makeshift. My rigs hook up to an
LDG Z-11 tuner with coax, then on the tuner's output it goes to coax again,
which goes to a 4:1 balun. One end of the balun goes to the antenna, the
other to some
Morning Stewart,
Many congratulations!! And putting your added filter ahead of the Varicap
tuned filter must prevent the varicaps being affected by the sum of strong
signals from the post mixer amplifier, in a wide bandwidth.

Geoff.
