"single-banders" . . . a low cost SSB transceiver for 10 or 15 meters . . . an SSB transceiver that's equal or superior to many wired rigs, but at much lower cost. It's the HW-100 five-band SSB rig with everything it takes to leave the rest of the field behind. How did we do it? We expanded on the Heathkit "single-banders" borrowed from the heritage of the SB-101, took a look at the competition, and produced the most SSB equipment you can get for the money. Here's what its got. You can check the specs and be impressed, but in general, the HW-100 operates with a hybrid circuit that uses 20 tubes (26 functions), two transistors (one an FET for the VFO), six germanium diodes, nine silicon diodes, and one Zener diode. Everything but the VFO, final amplifier, and various controls mount on nine circuit boards for stable, dependable, easy-to-build circuitry. Here's what it delivers. The receiver portion of the HW-100 has a sensitivity figure of less than 1/2 uv for a 10 dB S+NIN ratio for SSB operation. Crystal filter selectivity is 2.1 kHz at 6 dB down, 7 kHz at 60 dB down. Image and IF rejection better than 50 dB. The transmitter section in SSB continuous duty is 180 watts PEP, CW input is 170 watts on 50% duty cycle. It operates PTT or VOX on SSB, and CW transceive is provided by operating VOX from a keyed tone, using grid-block keying. CW side-tone is 1 kHz, internally switched to speaker or headphones. Carrier and unwanted sideband suppression is 45 dB down; third order distortion 30 dB down, RF compression (TALC) is 10 dB or better. Frequency stability is outstanding ... less than 100 Hz drift per hour after 30 minute warmup . . . less than 100 Hz variation under a 10% line voltage variation. And the HW-100 is the only rig that uses a Field Effect Transistor (FET) in the VFO for superior thermal stability. A pleasure to use. Everything you need is up front. Dominating the front panel is the Main Tuning dial ... a smoothly operating, vernier action control provides 28 revolutions of the knob per 500 kHz band segment, thanks to the use of the patented Harmonic Drive II mechanism a handy zero reset button is adjacent. Readout is on a large, circular, backlighted dial with 5 kHz divisions. To the left are the Band Selector switch, Mode selector, Load and Final tune, Driver preselector, Mic/CW Level control, Mic connector, and Phone jack. To the right is the S-Meter with a 3-position switch for checking ALC, Relative Power, and Final plate current. Adjacent is another 3-position switch for PTT, VOX and Calibrate. RF gain and AF gain controls complete the front panel. Located inside are controls for Meter Zero,' Bias, VOX sensitivity, VOX delay, Anti-Trip, Carrier Null, and Neutralizing. On the rear apron are the CW key jack, 8 ohm speaker output, ALC input, Power/Accessory plug, RF output, and Antenna connector. A pleasure to build. You build it all . . . even the VFO . . . yet it is easy. Most components mount on the nine circuit boards and one large wiring harness makes interconnections simple and fast. A handsome 2-piece green wrinkle finish cabinet is included. For the best value in SSB transceivers anywhere, put the HW-100 to work in your operation ... it's a winner!
