INTRODUCTION

The Heathkit Model HW-16 CW Transceiver is cryStal controlled for excellent stability, For
a high performance and economical amateur high selectivity, the receiver uses a 500 Hz
radio receiver and transmitter. Although it is crystal filter, The receiver is automatically
designed with the Novice Class operatorinmind, muted each time the key is depressed. providing

munications in the lower 250 kHz segments of

the 30-, 40,, and lS-meter bands. The following equipment will be necessary for

the initial test and alignment of the Transceiver.
The transmitter is crystal-controlled, using 1. An 11 megohm input VTVM (a 20 KQ/V
80-meter crystals on 80- or 40-meter bands, VOM may also be used).
and 40-meter cryscals on 40- or Iii-meter bands.
The Transceiver also has provisions for an ex-
ternal VFO.

2. A 50 $2 nonreactive dummy load that is
capable of 100 watts dissipation, such as
the Heathlcit Cantenna, Model HN-Sl.

Input power to the final stage is adjustable for 50 3_ Crystals:

to 90 watts input. A 75 watt marker on the meter. 7.030 MHz or slightly higher frequencv,
which indicates plate current, represents maxi- 3500 kHz or slightly higher frequency.
mum power for Novice Class Operation. All three 3750 kliz or slightly lower frequency.

stages of the transmitter are grid-block keyed.
The only tuning required when changing hands or
frequency is adjusting the final Tune capacitor.
