Links to sites not related to amateur radio can be found in my Bookmarks. Read my disclaimer. You pull his tail in New York and his head is meowing in Los Angeles.
Do you understand this? And radio operates qst october 2018 pdf download the same way: you send signals here, they receive them there. The only difference is that there is no cat.
Peterson has been very aggressive in stopping on-line manual downloads and sales. Downloadable Heathkit manuals are no longer available at BAMA or at the mirror or from other sources on the web.
Data Professionals offers printed copies of some manuals but at this time none are available for any of the Amateur Radio products ever offered by Heathkit. Their neat, compact design, low qst october 2018 pdf download and high versatility make them ideal for use in either mobile or fixed station installations.
All qst october 2018 pdf download 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.
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 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. Band changing and qst october 2018 pdf download 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. See notes here about installing a Freq-Mite in the HW He notes, "The extra pin of the 2N grounds the case, and it may be done with a small hole drilled into the PC board nearby the new unit, or the ground simple sic may be left 'floating' with no noticeable loss in performance.
Classic Heathkit HF Stations: DX The DX is an entirely new qst october 2018 pdf download, featuring increased power, clean keying characteristics and stability made possible by the efficient circuit design. An ideal rig for the novice who intends to operate on phone as soon as he gets his general-class ticket, yet needs a CW rig in the meantime. Experienced hams also will find the DX appealing since it provides the phone and CW facilities desired in a low-power rig.
The plate power input of the model DX is 75 watts on CW, and peaks to 60 watts with controlled-carrier phone modulation. It covers the 80, 40, 20, 15, 11 and 10 meters with single-knob bandswitching. PIP network coupling is also featured between the buffer circuit and the final amplifier thus improving stability and attenuating the higher order harmonics, reducing the possibility of television interference.
A line filter is incorporated to prevent RF radiation through the power line. The efficient oscillator and buffer circuit provides adequate drive to the amplifier from 80 to 10 meters even with an 80 meter crystal.
A drive control adjustment provides excellent maximum to minimum drive requirements. A five-position function switch provides an extra "tune" position, allowing you to switch on the oscillator without the final amplifier being on, so the operator can locate his own signal on the band.
Tuning the buffer stage to proper drive level before the final is on also prevents the possibility of damage to the final amplifier tube. The modulator circuitry features an audio frequency shaping network allowing a higher average output level on voice frequencies where it is required.
Provision is made for three crystals. A four-position switch selects any of the three crystals or a jack for external VFO. The crystal sockets are easily accessible through a "trap door" in the back of the cabinet. An external VFO variable frequency qst october 2018 pdf download can also be used to excite the transmitter for the general or advanced-class ham.
Power for the VFO is available at a socket on the rear apron of the chassis. Top-quality components are used throughout. The transformers are potted types, ceramic switches are used in the final RF circuits, all coils are pre-wound, etc. The circuit features liberal shielding and careful physical placement of components and leads for stable operation.
The circuit design has been extensively tested "on the air" with excellent qst october 2018 pdf download, assuring you of the best possible performance.
Besides being carefully designed both electrically and physically, the styling of the DX is outstanding. Two large knobs on the front panel provide smooth antenna and final tuning. Between them is a switch for the easy-to-read front-panel meter with a D'Arsonval movement that indicates final grid or plate current. The function switch is at the lower left, providing selection of off, tune, standby, phone and CW.
The drive control is in the center. The key jack is at the extreme left, and a pilot light is at the extreme right, qst october 2018 pdf download.
Its attractive and professional appearance is in keeping with the fine operation it can provide for you in your ham shack. You can build this rig yourself and be proud to show it off to your fellow hams.
Assembly instructions are complete in every respect. The manual contains complete step-by-step instructions that are tied-in closely with large pictorial diagrams, to prevent costly mistakes.
Assembly proceeds smoothly from start to finish even for an individual who has never built electronic equipment before.
Whether you are a newcomer or an old-timer, you will find the DX a very worthwhile addition to your ham shack. DX The DX Amateur Transmitter with its many design features offers more in quality, performance, and dependability than any other unit in its price and power class! Superbly designed throughout, the DX with its high quality components, clean, rugged construction and thoughtful circuit layout makes it an ideal "first" transmitter for the novice.

All parts are easily identified and a precut, cabled wiring harness eliminates much of the tedious wiring. The completed unit with its neat, functional panel layout provides for maximum ease of operation.
Circuit-wise, the DX features a built-in low pass filter for harmonic suppression, neutralized final for high stability, grid block keying for excellent keying characteristics and easy access to crystal sockets on the rear chassis apron. A front panel switch selects any of four crystal positions or an external VFO. Controlled-carrier modulator and silicon diode power supply are built in. Single knob bandswitching for 80 through 10 meters and pi network output coupling provide complete operating convenience.
A high-quality panel meter shows final grid or plate current to aid in tuning. In every way, the DX represents an outstanding amateur "buy. Less crystals. HR This handsomely-styled amateur receiver is a perfect match for the DX Transmitter, providing complete high-performance station receiver facilities at low cost!
The HR is designed for amateur band coverage only on 80 through 10 meters, for maximum accuracy and stability. Each band is separately calibrated on a large, easy-to-read slide-rule dial. The tuning dial is illuminated and provides over 6" of bandspread for precise frequency settings.
The 7-tube superheterodyne circuit features an RF stage for added sensitivity and employs a half-lattice crystal filter for excellent selectivity characteristics Two IF amplifiers operating at kc provide good image rejection. Other features include: "S" meter to aid in tuning and determining relative strength of received signals; a 3-gang tuning capacitor to assure proper tracking of all circuits rather than qst october 2018 pdf download Banding"; a front panel dial calibration control and provision for a plug-in kc crystal calibrator to provide accurate dial calibration at any kc point across the band.
