Heathkit SEM04 Amateur Transceiver

Probably the world's most advanced amateur transceiver— totally broadbanded, completely solid-state, true digital readout and much more. This transceiver is the standard others will be judged by for years to come.

Totally broadbanded. You can go from CW on the low end of 80 to USB on the high end of 10 in just seconds — and with perfect tune. At last, instant QSY. Just choose the band, dial in the operating frequency, select your mode and go - no more preselector, load or tune controls,

True digital readout with 6 easy-to-read electronic digits provides resolution down to 100 Hz on ait bands. There's no more need to rely on inaccurate dial tracking or questionable VFO linearity. True digital circuitry takes into account all three frequencies: VFO, HFO and BFO. You don't even need a calibrator.

Performance plus convenience. The transmitter delivers 100 watts output and, for GRP1ersT a front-panel switch instantly switches the output to one watt, And the four final transistors are protected against high SWR and thermal runaway, so they should never need replacement. The signal is clean and strong — low harmonic and spurious radiation, third-order distortion down 30 dB or better at 100 watts, carrier and unwanted sideband suppression down 55 dB. And broadbanding assures that it stays that way on all bands. Specifications alone don't do justice to the receiver's performance because we've dramatically reduced cross-modulation and intermodulation to increase useable sensitivity. And we didn't forget convenience — 15 MHz WWV position on the bandswitch, 30 kHz per revolution spinner knob, tune button for loading Jinears,, Pi f mike jack, pushbutton 100 Hz blanking, ALC/retative power/S-meter, switchable VOX with front-panel gain and delay, and much more,

Easy assembly and alignment. Eleven of the 15 boards plug in and seven can be extended out of the chassis while the transceiver is operating. Two wiring harnesses eliminate most point-to-point wiring, Alignment is fast and simple requiring only a dummy ioad, mike and VTVM.

The SB-104 operates directly from a 12V auto electrical system. For fixed station use, hook up the HP-1144 Power Supply.

Chassis of the SB-230,

Heathkit SB-2301kw Conduction-Cooled Linear

The new value in linears. The lowest cost conduction-cooled linear on the market.

Strong and silent. The "230" uses a husky Eimac 8873 triode in proven, stable, grounded grid circuitry to deliver up to 1200 watts PEP SSB, 1000 watts CW input from less than 100 watts drive, The "230" is also rated at 400 watts input for slow-scan TV and RTTY. A massive heat sink eliminates noisy cooling fans. And the final is completely enclosed in a double-shielded compartment.

Convenience. Bandswitching is done with a single knob-..Load and Tune controls are clearly marked so you can return to a favorite operating frequency just by noting the control positions. A five-position switch, coupled with the backlighted meter, indicates Relative Power, Plate current, Grid current and plate High Voltage at a glance.

Ttte business end of the new SB-230: a cci reduction-cooled E873 triode final and a highly efficient heat sink. Mo blower needed.

microswitch interlocks on both the top and bottom to shut down the primary power when the cabinet shells are removed. The heat sink for the 8873 is temperature monitored; if the temperature rises too high, a thermal circuit breaker opens, the linear shuts down and the Hi Temp light goes on. The Exciter light indicates the linear is running straight through, without amplification. To allow the tube sufficient time to warm up, a delay circuit is built-in, The On-Off switch also includes a built-in circuit breaker for the primary side of the power transformer. And the cathode of the tube is fused for additional protection.

1 mV sensitivity... 569.95 Kit, 775.00 Assembled

The Heathkit f0-4510 has vertical delay lines, 45 MHz typical trigger bandwidth and a maximum sensitivity of 1 millivoft over full vertical bandwidth. With a x10 probe, you can read waveforms to 10 mV/cm. The attenuator networks can be switched through 12 calibrated ranges to set deflection factors from 1 mV/cm to 5 V/cm.

Digitally-controlled time base circuitry provides automatic triggering for easy operation —no stability control is necessary. A reference baseline is generated when trigger signal is absent. Trigger Select switch and Level control allow time base to be precisely triggered at any point along positive or negative slope of trigger signal,The automatic position of level control triggers at zero crossing point.

Modes of signal display are selected by position control for each channel and Time Base switch. Either channel can be displayed as a function of time, or both can be displayed together chopped (200 kHz) or alternate modes automatically selected by time base switch. X-Y operation uses Channel 1 for horizontal deflection and Channel

2 for vertical deflection. Time Base control provides 22 calibrated time bases from 0.2 sec/cm to 0.1 ¿¿sec/cm in 1, 2, 5 sequence, continuously variable between switch positions.

An adjustable AC line switch matches the regulated power supply to any common line voltage from 100 volts to 280 volts AC.

Heathkit 10-4530,..perfect for TV service & home experimenting,.. 299,95 Kit, 425.00 assembled

You won't find a better TV service oscilloscope vaiue than the Heathkit IO-4530. Features like TV coupling, DC-1G MHz bandwidth, wideband triggering capability, sensitive 10 mV/cm vertical input, and calibrated X-channel input make it a versatile, easy-to-use scope for the service technician and a good general purpose scope for the hobbyist.

The 4530 Is one of the few single-trace scopes available with two input channels. The Y-input has a maximum sensitivity of 10 mV with an 11-position attenuator to set deflection from 10 mV/cm to 20 V/cm. For true X-Y operation, a calibrated X-input is provided with maximum sensitivity of 20 mV. its calibrated 3-position attenuator can be switched through three AC or DC ranges from 20 mV/cm to 2 V/cm.

High or Jew frequency waveforms are no problem since the 4530 s wide range of time bases can be switched from 200 ms/cm to 200 ns/cm. Any sweep speed can be expanded five times.

Trigger circuits are digitally controlled, requiring only a Level control and a Slope switch. In automatic mode, the triggering is at the zero crossing point. In normal mode, the level control is adjustable over the complete 8 cm span. Various trigger signals can be selected: a sample of the vertical input signal, a sample of the line voltage or an externally applied trigger signal. In the TV trigger coupling mode, the 4530 can be easily triggered on the vertical signai in a complex TV signal, Calibration requires a source of 1 volt, 10 kHz to 1 MHz square waves with less than 7 rts rise time and less than 1% overshoot (see iOA-4510-1 Oscilloscope Calibrator, page 68).
