[Elecraft] 144 MHz Transverter or rig?

Sat Apr 10 15:32:06 2004

Hi Lonnie e.a.

I have meanwhile built and installed the 144-28 ECK transvertor of Down East
Microwave. This transvertor fits into the K2 topcover and has excellent
specifications! I can recommend it to anyone that is not directly in need of
an inernal antennatuner/battery-option, as the transvertor takes the place
of that. But what I did is obtaining a second topcover of someone (thanks
Don/W3FPR, as you see I finished the transvertor!) that built a KPA-100 and
now if I want to go out portable on HF, I simply swap the topcovers.

First tests with an ATF54143 preamp (22 dB gain, 0.2 dB noisfigure,
mastnounted)shows marvelous RX performance on 144 MHz! The TX part provides
only 100 mW, but with a module-amplifier (Mitsubishi f.i.) it could easely
make 10-20W.

Best 73, Dick/PA2DW

I need input from the Elecraft community, please.

I'd like to be able to field a 2 meter ssb/cw station. While the performance
specs on the XV-144 are impressive, there are a few negatives for my needs.
The receive current may be too high for my power package to cope with, the
size is a factor and if I do decide that the K2 is the rig to bring, I can
only use one band (HF or VHF) at a time.

I own an FT-817 (filters battery and all) but it's a power hog and not a
great performer. I'm considering selling it now that I have experienced
Elecraft performance.

I'm intrigued by the "Hohentwiel" from QRP Project in Germany. I realize
that's it's only a five watt rig, but so is the FT-817. Otherwise it seems
to be closest to my needs.

I'd really appreciate as much input as you folks care to give. Reports of
personal experience with any of the rigs would be great.

Thanks and 73,

Lonnie
