All feature crystal-controlled transmitters and tunable superregenerative receivers with RF preamplifiers designed for operation on the 2, 6 or 10 meter amateur bands. The highly sensitive receivers pull in signals as low as 1 microvolt and produce complete quieting on reasonable signal levels. The transmitters with up to 5-watt input are more than adequate

for "local" net operations and the communication range of all models is unlimited under "skip" conditions. Other features include: a built-in RF trap on the 10 meter version to minimize TVI; frequency multipliers on the 6 & 2 meter versions to provide straight-through finals from an oscillator using a fundamental crystal in the 8 mc range; built-in final amplifier metering jack, and "press-to-talk" transmit/receive switch on the front panel with "transmit-hold" position. Kit includes a ceramic element microphone and two power cords, one for use with the built-in AC power supply and one for use with a vibrator power supply such as the Heathkit GP-11 for 6 or 12 volt mobile operation. Transfer from fixed station to mobile operation in a matter of minutes. Handsomely styled in two-tone mocha and beige. Less crystal. Whether you use it for standby, camping, emergency operation, or your primary rig, the Transceiver will prove its worth. Band changing and tune-up are easily accomplished with pushbutton band selection and single-control Tuning. The light-weight and compact Transceiver has pushbutton crystal transmit provisions for the novice or QRP roundtables. Main tuning is accomplished through a 6-to-1 vernier that is virtually backlash free. A Relative Powermeter, built-in sidetone, and carry-along size make the Transceiver a pleasure to operate. In HW-8 Handbook, First Edition (1994), Michael Bryce recommends replacing the...
