This view shows the shack in October, 2016. The
newest addition is an Elecraft KX2 transceiver.
The KX2 will serve a dual purpose.
First, it's a multi-mode, multi-band portable station to take to
the field. Second, it is a modern replacement for my
old FT-7 Yaesu rig.
My initial reaction to the KX2 is positive. It's been
used in several casual contest efforts (CW and SSB) and has held
up well. I've not done dynamic range measurements
yet. It was used for some FT8 contacts in 2018 where
it worked well so long as the power was kept to 3 watts output or
less. Higher output led to high PA temperature.
This photo shows a 25 watt linear amplifier that is used with the
KX2. It uses a junk box part (DV-2880T) operating at
25 volts. We have not yet built a low pass filter board with
band switching, so an appropriate filter is inserted from our
experimental stash of modules. The PA has been used on
all bands from 7 through 21 MHz. (2018 photo)
Below is a slightly earlier (June, 2016) view of the
station. Scroll down for a closer view of the main CW
rig. The aluminum panel boxes at the right are
experiments. The lower one is a direct conversion
receiver while the upper one is a frequency synthesizer that can
be routed to the main CW receiver.
The close-up is shown below. Additional info is
below the photo.
The box with the large black knob is the
receiver. The box with the meter is a QRP
transmitter that tracks with the receiver. The
chassis under the shelf is a 40 Watt MOSFET CW power
amplifier. This set-up, as shown, covers 40,
20, and 15 meter CW. The rig just to the left of
the QRP transmitter (just out of view in this photo) is a SSB
and CW transceiver for 6 meters. My
interests have moved away from VHF at the present, so the 6 M
transceiver sees little use. Perhaps that interest will
pick up as our sunspots continue to decline.
