T-150
TRANSMITTER
. The T-150 is a compact, high-power AM-
CW transmitter that's sure to rate a place
in your Ham setup. Providing bandswitch-
ing coverage of the 80 through 6 meter
8 bands, the T-150 operates at a power input
waren sont —— i - of 150 watts. Built-in AM modulation is
, provided by a combination of screen mod-
ulation and controlled carrier. Thus, at low
cost, practically the equivalent talk-power
of plate modulation is obtained.
Designed to provide a minimum of TVI,
¢ all leads going in-and-out of the cose are
bypassed for RF. There is more than ample
goin in the audio circuit to operote from
any high-impedance, dynomic or crystal
microphone. Keying is clean and chirpless

If

we
suggest
that

against
the

If

As

You
may

to
sort

USE ENOUGH HEAT
This is the main idea of good soldering. Apply
enough heat to the metal surfaces you are joining
to make the solder spread freely, until the contour
(shape) of the connection shows under the solder.
AN ELECTRONIC UNIT WILL NOT WORK...
unless it is properly soldered. Read these instruc-
ticns carefully to understand the basic ideas of
good soldering.
Enough heat must be used so the solder can actu-
ally penetrate the metal surfaces, making an un-
broken path over which electricity can travel, You
are not using enough heat if the solder barely
melts and forms a rounded ball of rough, flaky
solder,
Use the Right Soldering Tool
A soldering iron in the 40-100 watt range is recom-
mended, Any iron in this range with a clean,
chisel-shaped tip will supply the correct amount
of heat to make a good solder connection. You
may also use a solder gun but make sure the tip
reaches full heat before you solder.
Keep the iron or gun tip brightly coated with
solder. When necessary, wipe the hot tip clean
with a cloth. lf you are using an old tip, clean it
before you start soldering. Use a fine file or stee!
wool to expose the bright metal. Heat the iron and
immediately coat the tip with solder.
Use Only Rosin Core Solder
We supply the right kind of solder (rosin core
sofder). Do not use any other kind of solder! Use
of Acid Core Solder, Paste, or lrons Cleaned on
a Sal Ammoniac Block will ruin any Electronic
Unit and will Void the Guarantee.
HERE'S HOW TO DO IT...
1. Join bare metal to bare metal: insulation must
be removed. Make good mechanical connections
and keep resistor and capacitor leads as short as
possible, unless otherwise specified.
2. Coat the tip of a hot iron with solder. Then
Firmly Press the Flat Side of the Tip against the
parts to be soldered together. Keep the iron there
while you...
3. Apply the solder between the iron tip and the
metal to be soldered. Use only enough solder to
flow over all surfaces of the connection, and all
wires in the connection. Remove the iron.
Do Not Move Parts Until the Solder Hardens. If
you accidentally move the wires as the solder is
hardening, apply your iron and reheat.
4. Compare your soldering with the pictures on
this page. You have a good connection if your
solder has flowed over all surfaces to be con-
nected, following the shape of the surfaces. It
should appear smooth and bright and all wires in
the connection should be well-soldered.,
You Have Not Used Enough Heat: If your connec-
tion is rough and flaky-looking, or if the solder has
formed a round ball instead of spreading.
The difference between good soldering (enough
heat) and poor soldering (not enough heat) is just
a few extra seconds with a hot iron firmly applied.
Remember, larger metal surfaces take a longer
time to heat.
