MFJ 216 Deluxe "Amplifier Saver":

Amplifier Saver lets you safely tune up your linear amplifier
for full power output and best linearity. It protects your
expensive amplifier during tune-ups from over-heating, tube
damage, power supply stress and arc-over. MFJs innovative
pulse tuning technology lets you tune your amplifier at full
peak output power. It can also be used to evaluate wattmeters
and QSK systems.

It plugs into your rigs CW key jack. Simply press Pulse Tune
button and tune your amplifier normally for maximum power
output. It has Duty Cycle and Pulse Rate controls on front
panel, and is in a fully shielded all metal case. Uses 9 V
battery and measures a compact 3 1/4 x 1 1/4 x 4 inches.

This unit works fine and looks very close to new. MFJ sells
these for $80. But this one for $60.


MFJ "Strip Line" Coaxial antenna switches:

Both of these antenna switches are in a heavy diecast housing
that utilizes "stripline" construction to keep the impedance
very close to 50 ohms. It also permits good operation at
higher frequencies up to 500 MHz, and gives over 50 db
isolation. Unused antenna are grounded, with an additional
position to ground all antennas. SO-239 connectors.

also. $24


MFJ 8043 Electronic Keyer:

This is an electronic keyer that uses the Curtis 8043
Keyer IC. It has speed, weight, tone, and volume
adjustments.
It is capable of fully automatic or semiautomatic (like
a bug) operation. Also, it can emit a solid "key down"
for tuning up. It works with tube or solid state transceivers.
It has sidetone with a front panel volume and tone control.
Weighting is adjustable from the front panel. It can be
powered via four internal C cells or an external 6 to
9 volt DC power supply.

The styling of this unit is the wood grain and eggshell color
that TenTec used with their early equipment. TenTec made
the enclosure for MFJ, so it is an exact match.

This particular unit looks really great, and of course
it works. Paper work is included for $35.
