HF Miscellaneous Equipment
This is the original SGC-2020 HF transceiver made in Washington State to
milspec standards. It is a little unusual to operate, much like a VHF/UHF
hand-held radio with its various pushbutton combinations to accomplish a given
task. Once set up, however, it is a pleasure to operate and once I figured out
which buttons to push, I called "CQ" three times each resulting in a pleasant
contact. The transmitter puts out up to 25 watts through out the 1.5-30 MHz.
spectrum on CW or SSB.
The QRP crowd loves this unit since the power is easily varied from just about
nothing up to the 25 watt level. One can run this thing on D-cells if the power
is kept low. I have run mine on a 15 A/H gel-cell battery with good success.
There is a factory upgrade presently available from SGC that adds digital signal
processing to the receiver. I think the cost is around $200-plus right now and
it requires sending the unit back to Washington. I haven't done it yet, but I
think it would be a useful upgrade.
TenTec of Sevierville, TN produced many innovative
transmitters, receivers, and transceivers since their early QRP kits. The
"Argonaut" was an early solid state HF transceiver that was popular and was
competitive with the imports. The "Paragon" above was their first attempt at
producing a high-end amateur transceiver with all the "bells and whistles"
useful to a versatile amateur operator. Although I made lots of contacts with
mine on the ham bands, I especially liked all the analog filters, both I.F. and
audio that enhanced listening to the 160-190 KHz. experimenters' band. The
receiver is excellent and was just about the ultimate until digital signal
processing came along. I also have the matching power supply, but prefer to use
an RS-35M with it.
Yaesu FT-101B. An early SSB transceiver offering from Japan
that became extremely popular in the USA due to its outstanding performance and
versatility. The FT-101 series set the standard for future imports and my "101"
still holds it own on the HF bands. Note that the entire transceiver including
power supply is in one "box."
This is my stable of Trio/Kenwood 599 series transmitters and
receivers from the 1970's. They all are functional but I lack even one special
transceive cable to connect one to the other for transceive operation. The
cables generally cost as much on E-Bay as one of the individual radios.
Nonetheless, they can be operated separately quite satisfactorily and do a
remarkable job for early hybrid equipment from Japan.
Kenwood produced the TS-120 just prior to implementation of
the WARC band additions to the amateur spectrum. The TS-130 succeeded it and
covered these new frequencies. Both models make excellent mobile transceivers.
In the 1950's, Morrow manufactured some decent AM mobile
gear. These units were often used as a complete receiver in conjunction with a
homebrew transmitter. The 5BR tunable converter was sometimes used alone with
the car radio which provided the I.F., detector, and audio. Morrow also made
some fine mobile transmitters.
The Elmac AF-67 transmitter was one of the best of the 1950's
mobile units. It covered 160-10 meters and featured a plate-modulated
transmitter for AM phone operation. The RF amplifier is a 6146 and the
modulator uses a pair of 6L6's. The internal VFO is quite stable, so CW can be
used on the lower bands when running mobile. I had an Elmac station in my car
in the early 1960's and it performed very well using a "Master Mobile"
E. H. Scott made some of the finest commercial entertainment-grade receivers of the
1930's. During and after WW II they produced multiband shortwave receivers for maritime service. With
push-pull audio output tubes, the sound is robust. The receiver audio was usually tied into the ship's
600-ohm PA system to provide programming for the hands. I find it to be an excellent shortwave broadcast
receiver but the CW function is mediocre, probably due to low injection to the detector.
