Manual Overview

The Heathkit HW-2 VHF FM Hand-held Transceiver manual provides detailed operational guidance, focusing on troubleshooting, diagnostics, and maintenance. For troubleshooting, the manual emphasizes ensuring correct battery installation and observing polarity, as incorrect setup may lead to operational issues. It advises against opening the transceiver or adjusting internal components like coils or trimmers, as they are factory-set for optimal performance. Calibration involves using the thumb wheel switch for frequency selection in 10 kHz increments, with additional adjustments possible via the DIAL/+5k switch. The transceiver supports two power levels, selectable via the LOW/HIGH switch, and includes a squelch control for noise reduction. Error diagnostics are not explicitly detailed, but operational checks include ensuring proper antenna connection and battery case installation. For board-level guidance, users are advised not to mix battery types or use non-recommended power sources, as these can affect the device’s functionality. External connections are available for an S meter, speaker, and microphone, with specific impedance requirements outlined.

Quick Issues Covered

• Diagnose power-up failures by checking battery polarity and connections.
• Adjust squelch to eliminate white noise from internal speaker.
• Avoid adjusting internal coils or trimmers; factory-set for optimal performance.

Controls & Indicators

Thumb Wheel Switch: Selector for transceiver frequency in 10 kHz increments. DIAL/+5k Switch: Adds 5 kHz to the thumb wheel frequency. LOW/HIGH Switch: Selects transmitter power, LO – 0.4 W and HIGH – 2.0 W. Push to Talk: Starts transmission when pressed. OFF/VOL: Combination power and receiver volume control. SQL: Squelch control, increasing clockwise. R1/S/R2 Switch: Repeater offset switch for adjusting transmit frequency.

Installation / Setup

The installation of the Heath HW 2 VHF FM Hand-held Transceiver involves connecting the antenna to the BNC connector and removing the battery case from the transceiver. To install batteries, place 6 AA batteries in the battery case, ensuring correct polarity, and reattach the case to the transceiver until it clicks into place. The belt clip should be installed using only the screws provided. It is important to follow general precautions such as observing battery polarity, not mixing battery types, and using only 9V power sources.

Operation

To operate the Heath HW 2 VHF FM Hand-held Transceiver, follow these basic steps:

1. Use the Thumb Wheel Switch to select the transceiver frequency in 10 kHz increments. The most significant digit is in MHz, and you add 140 MHz to the Thumb Wheel setting to determine the frequency.

2. The DIAL/+5k slide switch can add 5 kHz to the Thumb Wheel frequency when set to +5kHz. In the DIAL position, the frequency is as indicated on the Thumb Wheel.

3. Select the transmitter power using the LOW/HIGH switch: LO for 0.4 W and HIGH for 2.0 W.

4. To start transmission, press the Push to Talk (PTT) button. Release it to enable the receiver.

5. Use the OFF/VOL control for power and receiver volume adjustment.

6. Adjust the squelch level with the SQL control by turning it clockwise to increase the level.

7. The R1/S/R2 switch is for repeater offset settings. In the S position, the transmitter and receiver frequencies are the same. In R1, the repeater offset (600 kHz) is subtracted from the Thumb Wheel frequency to obtain the transmit frequency. In R2, the offset is added to the Thumb Wheel frequency.

To begin using the transceiver, switch on the power and adjust the volume knob to mid-scale. Turn the squelch knob clockwise until no white noise is heard. Press the PTT button to transmit and release it to receive.

Safety & Warnings

General Precautions
– When installing batteries, observe the polarity.
– Do not open the transceiver and do not attempt to adjust the coils or trimmers. They are adjusted to optimum settings.
– Avoid using the transceiver in hot, humid or dusty places.
– 12V power sources cannot be used. Only use 9V power sources.
– Do not mix battery types. Do not mix old batteries with new batteries.
– Do not dispose of batteries by burning since they may explode.

Installation
– Install the belt clip. CAUTION: Do not use any screws other than those supplied with the transceiver.
