I recently built the rf power meter discussed in the last QEX and QST
issues. It was a fun project and works very well. However, it needs to
be calibrated and this requires either an accurate (i.e. calibrated)
reference meter or a calibrated rf signal generator capable of -70 dbm
to +7 dbm (or

the K2. I called

Check back in Jan 2004 QEX. There was a construction article on a nifty
little calibrator that you can build cheaply that would work perfectly.
It was written by K3NHI. It used a CMOS clock, battery and a few other
parts, and only requires a DVM to calibrate.

Hello Martin:

the K2. I called CQ using the 1.5 KHz CW filter on 20m and got response
from a couple of US stations.

a call sign and to give answer.
Howard,
There are alternatives to using another signal generator (and how do you
know you can trust its calibration) --
The Elecraft XG1 provides 2 levels that may be usable for calibrated lower
levels (-107 dBm and -73 dBm), and a calibrated 'scope that has adequate
vertical sensitivity along
I have a K2/100 SN 4853. It works fine except I sure do not understand a
part of the instructions for the KDSP2. Let me explain:
I can follow the instructions up to page 26, the bottom of the page. There
is has a heading, KDSP2 filter display. Just above this heading is the

My K2 being my first rig with a switchable preamp,
I find myself wondering which RST I should give, in a
situation where I think the other op is interested in
the real or actual RST, whatever that might mean.
Is it the strength with or without the pre-amp
switched in? Which would YOU prefer
Signal strength is all relative unless everyone has a calibrated S-meter
using the same parameters. I would give him the report I have using the rig
in the mode I'm in at the present. Whether or not that you have a preamp
running shouldn't matter as its all subjective. If he wants to know

Dear Martin,
If your narrow filters are aligned using the Spectrogram software so
that they are all centered on your cw tone (say 600 Hz), then all you
need is to zero beat the signal while in the 1.5 kHz filter, and then it
will stay centered even at 100 Hz. The instructions for finding and
Lloyd,
The world of signal reports is not really well defined, and often a signal
can receive a 599 (or 59) report even if the s-meter is at the bottom - it
all depends on how crowded or noisy the band is at the time. Just report
what you think or what you see on the meter and all will be well.
Steve and all,
I beg to differ - for 2 reasons
First, centering a 1.5 kHz bandpass on 600 Hz will result in the passband
lapping over into the opposite sideband by 150 Hz. A preferred method is to
set the 700 Hz filter first (centered on 600 Hz) and then observe where the

Order a F-50-43 core. Take two #26 enamel insulated wires about 2'
long. Clamp the start for the pair with about 2 from the end, to the core
with a cable tie. Wind the pairs through the center. Every time it passes
the outside, run the pair through a piece of heat shrink tubing, as
