1930's Homebrew CW TX. This was built from a March, 1937 QST article by =

George Grammar. It is a 19" rackmount requiring 10.5" of rack space. It =
has=20
a steel chassis and I think the panel is steel too. I have a copy of =
the
construction article. This was designed to use an 804 tube in the final =
but
this one had an 803 in the final when I found it. Uses plug in coils =
but
these are mostly missing. It is not built exactly according to the =
article
but it looks to be pretty close. No power supply. As-is. Needs work. =
From
the estate of 8AIG. $55 =20

Homebrew HF transmitter using a single 813 in the final. This is a =
huge,
rackmount transmitter with power supply. The transmitter uses about 20" =
of
rack space and the power supply is about the same. This is a =
bandswitching
rig with no plug-in coils. Very dirty and with much surface rust on =
many
components, especially in the power supply area. I know nothing about =
this
unit. The power supply must weigh 70 or 80 pounds. Untested. As-is. $70

National NC-100X receiver. This was the first of the National =
sliding-coil
receivers. It is a 1938-vintage general coverage receiver with National =

dial,=20
tuning eye and the famous sliding coil assembly for band changing. With
Crystal=20
filter and matching speaker. This is the radio with the famous red and =

other material I have gathered over the years on this radio. =

is

TU.
This is a single channel from a dual unit. It fits in =BD of a 3.5" =
tall, 19"
rack panel. No marking on controls or elsewhere. The filters in this =
unit
look home-made and are for 850CPS shift. This has a plain aluminum =

Jefferson Travis JT-350A Transmitter/Receiver. This is a relatively =
rare
WWII-era Army AAF transmitter/receiver setup used at temporary =
airfields. It
was never assigned an SCR- or BC- designation because it was not a =
Signal
Corps product. These were acquired by the AAF prior to the AAF falling =
under
the jurisdiction of the Signal Corps. This one is in nice cosmetic
condition. It had been modified with an SO-239 in place of the original
ceramic antenna post but I put the original ceramic post back in place.
These use a pair of 807's in the finals modulated by 807s. The other =
tubes
are all loktals. This one comes with the shockmount, 350PS AC power =
supply
and all cables. The power supply has the transit case (which is a =
wooden
crate). This thing is huge and will be costly to ship. Untested. As-is. =
$250

antenna
coupler that takes 1 RF input to 6 or 8 RF outputs. It is a 5.5" =
rackmount
unit. Inputs and outputs are BNC connectors. It uses one 7768 tube and =
7
5842 tubes. The antenna connectors can be brought out to the front or =
to the
back. I worked on this a bit and replaced the butchered military power
connector with 3-wire grounded line cord. It has an isolation =
transformer
setup in it called the "PS-1 voltage regulator." This unit was bad and =
I
left it in the box, but it is disconnected. The 3 paper Electrolytics =
in the
power supply PS-2 were bad and I replaced these. $15
