Prior to the availability of affordable synthesized transceivers under microprocessor control, Ham radio operators needed to tune a continuously variable local oscillator (internal or external) or have a selection of crystals for specific frequencies. Even by 1982 microprocessors were relatively expensive, so equipment incorporating them was also pricey. Heathkit's model SS−9000 claimed to be designed by amateurs for amateurs, and was "so feature-conscious, it has no options." That's right, anything and everything that could be imagined was included in the base model; there we no upgrades. It used a high accuracy and stability internal 10 MHz reference oscillator for the PLL synthesizer. Also incorporated was an RS−232 serial port for control via computer (up to 9600 baud!), such as the Heathkit/Zenith personal computer (the IBM PC had hit the market in the prior year, and the the Radio Shack TRS−80 and Apple II had been around since 1977). The SS−9000 was solid state throughout (likely where the "SS" prefix originated). The unit was evidently so sophisticated that it was only offered in a fully assembled and tested form, which was fairly rare for Heathkit. By 1982, they were probably having products like this assembled overseas. This info was scanned from my hard copy of the Heathkit 1982 Christmas catalog.

Heath SS-9000 Deluxe Synthesized HF Transceiver - RF CafeHeath SS-9000 Deluxe Synthesized HF Transceiver

Introducing a breakthrough for Amateur Radio - the Heath SS-9000 Deluxe Synthesized HF Transceiver. It's microprocessor-based, computer-controllable ... and ready to take on tomorrow

For years, Amateur Radio has awaited the advent of computer-aided communications. Today, there's a new generation of contact beginning as the era of 'micro' enhanced ham shacks arrives ... ushered in by the SS-9000. It is one Transceiver against which all future gear must be compared.

• This is the Cadillac of transceivers: Fully microprocessor-based, entirely solid-state, broad banded in design delivers 100 watts to a 50 ohm load

• Microprocessor circuitry controls the entire operation of the SS-9000

• A built-in Terminal Interface with an RS-232 I/O port allows instant and direct control of operating parameters via ASCII terminal, modem or computer

• Nine-band operability, including the newly-allocated 10, 18 and 24 MHz WARC bands and WWV at 15 MHz

• An idea whose time has come - unlike anything that has preceded it, the SS-9000 challenges every previous resource of skill and imagination

Readers of the many amateur-oriented magazines such as QST, ham radio, CQ, World Radio and 73 have been quick to grasp the future potential of computers in application to their worldly hobby. More than any other single station accessory, the microcomputer can add a wealth of powerful capability and fast organization to an operator's air practice. With the assistance of a terminal, and a Transceiver that can be thoroughly governed by keyboard commands, an experienced Amateur could have greater control over all phases of contact, reams of important data at his fingertips and enviable advantage on the air. The speed and performance characteristics of such a combination would put new meaning in the overused words 'state-of-the-art.'

No better time than the present: The promise of this vision has evolved into an American design that surpasses all expectation. Anticipating the evolution of Amateur Radio, the hams at Heath engineered the SS-9000 and PS-9000.

Designed as a tool for development and discovery: No one else offers capability to compare with the SS-9000 Deluxe Synthesized HF Transceiver. The magnitude of its manageability gives the pacesetting ham an opportunity to break new ground, and promote the applications of computer technology.

Completely synthesized for absolute accuracy: A 10 MHz crystal-controlled master oscillator produces a reference frequency that is clock-divided to phase-lock the IFO, HFO and BFO. This action affords superlative stability and repeatability during long hours of operation. A Single precise VFO is tied to each display through the 256 bytes of CMOS Random Access Memory. For the operator who is accustomed to several nets, DX hot spots, favorite call channels or listening points and more than one scheduled band rendezvous, this extra storage capacity accepts three separate inputs per band, for a total of 27 frequencies to recall and work at will.

Two displays are better than one: The most outstanding feature of the SS-9000 front panel is its unique dual frequency readout. Smart contesters and DX hunters know that it's more than a cosmetic frill. Dual readouts let you transmit on one frequency and receive on another, or maintain one frequency while scanning for a better one. Transceiver on either the left or right display. Toggle their function from T to R. Copy from either display to memory, or exchange either with the frequency stored in memory. Place it under terminal control, and enjoy a versatility in QSO capture that shatters all precedent.

A receiver to be reckoned with: The SS-9000's advanced front end is highlighted by twelve poles of distributed SSB filters for optimal selectivity, 0.3 μV sensitivity and a phenomenally high third order intercept point. Audio gain is typically 30 or better, with one result: Typically fantastic results! Three switchable filters provide extra selectivity for the critical CW operator. A controller circuit forms the "intelligent' heart of the SS-9000. This device acts as a serial interface between external requests, via front panel controls and terminal interface, and the internal circuits on the synthesizer, T/R and audio circuit boards. The controller consists of a CPU, a peripheral interface adapter (PIA), a static memory interface, a read only memory (ROM, for the program sequence) and 256 bytes of CMOS random access memory (RAM).

The Terminal Interface Package (EIA standard RS-232C) installed within the SS-9000 allows you to control and monitor the Transceiver from a video terminal (such as the H-19 on pg. 71), hard-copy teletype terminal, or computer (such as the All-In-One Model H/Z-89 on pg. 68). Remote Transceiver control is also possible over telephone lines with a modem. Commands built-in to the Transceiver controller allow you to select, display and change the band, mode, up to 27 operating and memory frequencies, passband shift, band scan and baud rates. You can also place the Transceiver in transmit or receive mode, toggle the dual readout for T/R/Tr operation plus exchange the one memory and two displayed frequencies at will. The SS-9000 will respond to unacceptable requests at the terminal, with a numeric error code. When the available commands are combined in a program or sequence, many more useful functions may be implemented at high speed.

You can interface the SS-9000 to a personal computer using a standard RS-232 cable if it has a port configured as DTE (Data Terminal Equipment). The software package supplied with every SS-9000 is written for connection to port 3300 (octal), on an H/Z-89 with 48 kilobytes of RAM operating under HDOS and the MBASIC language. This 5 1/4" floppy diskette demonstrates only one of the many ways of providing communication between a computer and the Transceiver, using animated graphics and video text to thoroughly introduce an owner to System 9000 and its amazing control capabilities.

An SS-9000 can be connected to the Heathkit SA-1480 Remote Coax Switch. When changing bands (either manually or via remote control, using the built-in Motorized Band Switch) the proper antenna is selected automatically.

Data flow speed-customized for any terminal: Baud rate is initialized upon power-up. With an 8-position dip switch on the front panel circuit board, you can select any of 15 different baud rates between 50 and 9600 bits per second. Half of this same switch is used to control the rate at which readout frequencies change when the up/down band-scanning buttons are pushed.

A Transceiver so feature-conscious, it has no options!

RS-232 Terminal Interface offers communication between the Transceiver and external ASCII terminal or computer. Motorized Computer Bandswitch rotates the band selector to desired setting under remote control.

Extended memory allows storage of three frequencies per band, and memory preserved up to one year with battery backup. Unique dual digital display offers new versatility in frequency - handling speed and agility. Four T and R indicator LEDs identify which display is controlling the transmitter and receiver, or if either display is to transceive.

Front panel and main circuit boards are hinged for easy access. Main tuning knob has optically-encoded shaft for smooth, linkage-free control and zero backlash.

Diode-balanced mixers and dual-gate MOSFETs provide higher sensitivity and dynamic range. Superior over-current, thermal and high VSWR protection means you can operate worry-free.

Durable, die-cast zinc front panel gives precise signal control, and includes: selectable VOX with variable delay or PTT operation. Receiver Incremental Tuning. An adjustable RF speech processor. Plus and minus passband shift. Impulse-type noise blanker. RTTY capability. Fast and Slow AGC with OFF position. Standard fitters tor CW-wide and CW-narrow selectivity. Pushbutton up and down band scanning in 16 selectable rates with 100 Hz resolution. A four-function meter which indicates received signal strength, ALC, relative power and compression level.

Commands are provided to control and monitor all functions of the Transceiver that are under microprocessor direction. The same commands that set a parameter to a particular value can also be used to examine a current value.

Commands are also available to Lock and release one or all switches to their terminal-controlled or physical states, print the switch settings (with appropriate "L" indication), print the frequencies in memory for all bands, print the memory frequencies for a particular band with receive and transmit assignments flagged by T and/or R, toggle the T and R indicators for the current or any particular band, plus set the Receive and Transmit mode. These displays may be limited to a particular frequency register or switch setting by following the command with one of several symbols, operators, constants and band specifiers. The special manual which arrives with System 9000 gives complete details on operation, installation and configuration.

The PS-9000 Power Supply/Speaker is a perfectly matched component for the SS-9000, providing 13.8 VDC for base operation with high temperature, short circuit and current surge protection. Each digital clock has independent 12- or 24-hour capability and fast/slow set buttons for local/UTC timekeeping.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
