Ameritron AL-84 HF Amplifier:

The Ameritron AL-84 is a grounded grid linear amplifier
using four 6MJ6 tubes driven thru an impedance matching
and power swamping network. It has a pi net output, and
an illuminated meter that reads plate current and voltage.
There is a connector on the back that will furnish 12 V
DC at low current for such things as lights on an antenna
tuner, powering a keyer, etc. The AL-84 is rated to deliver
400 watts when driven with a 100 watt rig.

This particular unit has had the 10 meter mod done, so it
covers 160 thru 10 meters. It works fine, producing rated
power, and looks almost perfect.

With paper work for $400.


"Wall Wart" Power Supplies:

All of these are "regular" wall warts -- not the new
switching type that create all sort of noise in your
receiver. Get one of these, and leave the noise behind.

MFJ 1312 B
This unit provides 12 V DC at 300 ma. It has a 2.1 mm
coaxial plug with the center positive, and is often used
for keyers, lighting tuner lights, and other small misc
jobs where 12 V DC at low current is needed. $12

9 Volt DC at 500 ma
This one was used on a MFJ 422 keyer, but will also power
other items needing 9 V DC at low current. It has a
2.5 mm male plug on it. $12

AEA AC-1
This unit supply 12 V DC at up to 1 amp.
It can be used with the AEA PK-232, PK-88 or others.

positive, so it can be used on many different
things that require about 12 V DC at up to an amp,
such as keyers, antenna tuners, etc. $14

other HTs.

Daiwa CS-401 Stripline 4 Position Coax Switch:

Daiwa switches utilize professionally engineered all
metal cavity construction for maximum efficiency, high
isolation and minimum resistance. Isolation is better
than 60 dB at 300 MHz. Insertion losses are less than
0.2 dB. The Daiwa CS-401 permits the selection of up
to four antennas. Unused antenna positions are grounded.

Freq. Limit 800MHz
Power Rating 2.5 kW PEP 1 kW CW
VSWR below 1:1.2
Insertion Loss < 0.2dB
Isolation 60 dB at 300 MHz
Connectors SO239

This one works fine with great switching action. $70


Coaxial Lightning Arresters:

These lightning arresters are made to be inserted in to
your coaxial feedline, to help reduce lightning damage.

Cushcraft LAC-2
Still in the original blister pack, unused.
This one has an SO-239 (female UHF) connector on each end,
so that a PL-259 can be screwed into it. $15

Cushcraft LAC-1 ??
No markings on this to confirm the model number, but it
looks like the Cushcraft "Blitz Bug".
It has an SO-239 on one end and a PL-259 on the other end
(female UHF on one end and male on the other). $10


Coaxial Cable:

I accumulated a fairly large amount of miscellaneous
lengths of coaxial cable. Most of the cable is RG-8
(.405 inches in diameter) or equivalent. Most has a
PL-259 on at least one end, and most on both ends.

All of the coax over 20 feet has been checked with an
analyzer, and its loss has been confirmed to be within
10% of new specs which is as close as I can measure.
Lengths under 20 feet have been checked for continuity,
because loss is almost impossible to measure for lengths
this short.

I have a large amount in many different lengths, varying
from 1 foot to 80 feet. To put it another way, I have
jumpers for in your shack, and lengths to run up your
tower. I can not list all of the lengths. Please let
me know what you need, and I will see how close I can come.

The coax is 3 feet for a dollar (33 cents a foot), plus
$2 for each installed PL-259, plus shipping from Florida.

Most are unused.
