The DigiBrain's Brain I think we all know a little about microprocessors and central processing units (CPUs). These gadgets run in computers and crunch numbers as well as driving monitors and writing data to our printers and so on. The difference between a microcontroller CPU and a more mainstream chip like the Pentium or 68040 is the amount of support chips needed. A microcontroller is often connected directly to LEDs and switches. It needs a minimum of external parts, as it has its own dedicated I/O ports as well as scratch RAM and a program burned into EPROM (or EEROM.) A chip like the Pentium needs outboard RAM, memory controllers, I/O buffers and gobs of "glue logic" so all these components work together properly Choosing a CPU Some people get all bent out of shape over one brand of CPU versus the other. I say, "Look at the cost and what you want to do with it!" The Motorola 68HC705J1A family, which I used, has some good feature--but than so do the Intel Zilog, Parallax and many other chips. In fact, the first version of the DigiBrain used an old Intel 8751 and it worked just fine! My final choice of the 68HC705J1A was (as usual) cost, cost, cost, availability and maybe a chance to challenge my programming skills. The version I used comes in a skinny 20-pin package with 1.2 kbytes of EPROM and a handful of RAM. The trick would be cramming everything into this tiny package. Some of you are probably giving this account the fish eye, as it seems impossible to program anything useful in 1 kbyte of RAM, right? I mean, everyone knows that Word 6.0 for Windows fits on a dozen 1.44 megabyte disks. Well, just remember that the earliest home machines, such as the Altair and Intelec8, started with 256 bytes of RAM and later moved up to a whopping 4 k. People managed to get these machines to do all sorts of clever stuff. The trick was careful coding in assembler! (Seeing how long some of today's programs take to load, you might wish that a few more people had developed that assembler programming skill Design Tools One of the things going for the Motorola CPU was its cost The one-time-programmable parts are surprisingly inexpensive. When I ordered my 68HC705J1A designer's kit, it only set me back $99.95. I looked at the development kits for other popular microprocessors and they all cost $200 on up! The Motorola kit comes with an integrated editor/assembler/debugger as well as a programmer that plugs into your PC's serial port and a sample of the erasable version of the part. The surprise was that the programmer card doubles as an in-circuit emulator. A software emulator lets you simulate a microprocessor (such as the 68HC705J1A in software on a different computer (such as your generic PC)--a very useful thing to have while testing snippets of code. Remember, though, that Motorola supplies a software and hardware emulator. This gadget allows you to plug a cable into your new design and run and simulate the action of the CPU. Thus, without programming any 68HC705J1A parts with alpha or beta versions of my program, I was able to try routines and program the Harris DDS and so on! This also allowed me to determine which CPU input was which on my bungled prototype board I think the reason this seems so fantastic to me is that the last chance I had to use such a device was when I was working on a 68000-based computer. The Hewlett-Packard in circuit emulator I used cost our company 30+ kilodollars Although it was a tad fancier than the one offered by Motorola for 99 bucks and change, the functional differences aren't worth mentioning. As I've said before, we are indeed living in a new golden era of designing and constructing ham gear at home. With tools like these, new and wonderful gadgets can be designed quite easily Making It Fit At first glance, the 68HC705J1A (what a mouthful) didn't appear to have enough I/O lines for the DigiBrain project Then I remembered that I was dealing with a real CPU. It was simply a matter of using the chip's Port A as my 8-bit data bus and turning this into two separate 8-bit ports for LCD and DDS control. This required a set of 74ALS574 latches and two bits from Port B--pretty good, synthesizing 16 bits from 10! To write the LCD, I send the byte to Port A and toggle the latch bit to the LCD 74ALS574 (U3). If I want to write to the DDS, I write my data to Port A again and toggle the latch bit to the other 74ALS574. I also decided to use the LCD module in 4-bit-data mode. (I had to do this because I needed an additional three lines to control the panel.) I suppose I could've simply added a third 74ALS574 for a third port to control eight extra output lines. But doing so would have raised the DigiBrain's cost and lost that "spare" I/O line on Port B--and I can't forget Craswell's Law: Software once written and working, of course) is cheaper than hardware.--WBOVNE

Nearly everytime you construct a new piece of equipment you have to design some filter. It's exactly the same for me!

The program GEOST is designed as an aid for the installation of antenna systems for geo-stationary satellites. All such satellites are placed in a circular orbit above the equator. Their angular velocity is equated to the angular velocity of the earth, in order to maintain each of them always above the same point of the earth surface. Therefore, tracking a determined geo-stationary satellite is a trivial operation, as any observer sees it as a motionless object in the sky. However, the problem which arises is that of installing the antenna system in such a way that it is always directed towards points lying on the orbit of geo-stationary satellites, when it is rotated in any direction, since in this way it turns out to be easy to have access to different satellites section 9). The program GEOST supplies the values of azimuth and elevation for three "pilot" satellites which are denoted by Western", "Central" and "Eastern" respectively (see section 3 One should choose those which are more appropriate for the given location. The idea is to assume as "Central" the satellite which is more or less positioned on the same meridian circle as the site of the user. The "Western" and"Eastern" satellites are the extreme ones in the West and East directions respectively, among the ones seen by the observation point or, otherwise, among the ones which the user wants to receive. The program also displays the elevation under which the antenna sees the culminating point of the geo-stationary orbit: this value is generally equal to the elevation of the central satellite, if its choice has been made in a reasonable way. The last value provided by GEOST is the difference between the direction of the meridian of the observer and his azimuth bearing for the central satellite: this allows an easy calibration of the geographic orientation: in fact, the compass is not accurate enough for our goals. The difference is computed with respect to the South direction for the points on the boreal (northern) hemisphere and with respect to the North direction for the points on the austral (southern) hemisphere

GREAT CIRCLE is a program for use by amateur radio operators.  Its purpose is to provide antenna direction from one amateur radio station to another.  This program calculates, draws and displays a great circle map using the home QTH as the center point.  The map will contain the location of both stations, the path, and antenna direction and distances between the two locations This program was compiled using Borland's Turbo C 2.0 for DOS.  The program was tested using 8088, 286, 386 and 486 computers.  But requires a VGA monitor.  Computers with floating point hardware create the map much faster than those requiring software emulation.  After the map is created it is saved to a file.  Each time the map is displayed, it is loaded from the file into the video memory.  Recalculation and recreation of the map are only necessary if the home QTH information is changed A data base containing world wide call areas, latitude, longitude city and country names is included.  A simple editor is provided to delete unwanted locations, add new locations and modify or correct existing records in the data base.  The data base is loaded into memory when the program is started Using this programming method, the data base must meet a size requirement not to exceed 64K bytes, which is about 700 records.  The included data base contains about 550 records of data with room for about 150 additional records the user can enter.  Unwanted records can be deleted and replaced with desired location data.  This will allow the user to tailor the data base to his particular need A great circle map is drawn using coordinate data created by the Central Intelligence Agency and placed in the public domain by Fred Pospeschil and Antonio Riveria.  Each mapping point and segment is read from a file. The distance and direction from the user's home QTH to that point is calculated The result is converted to x, y coordinates and  displayed on the monitor as a pixel or line segment.  The coasts of continents and islands are drawn, the water areas are color filled and the map is saved to a file for loading upon request When the operator enters a call area or location of a desired station, the data base is searched for a match to the request.  If found, the great circle map is loaded and displayed with the path drawn between the two locations The antenna direction, distance and location of each station is also displayed

IDFREQS (IDentify FREQuencieS) is a program written for scanner owners that allows them to print out a list of all frequencies stored in their scanner, along with text descriptions of agencies that use them.  Since some scanners will actually "round" a frequency when entered, and since you can actually hear frequencies that are just a few khz off of center, IDFREQS considers frequencies that are within 3khz of each other as the same IDFREQS first loads a file that you create containing channel numbers along with the corresponding frequencies, currently in your scanner Next, master frequency data base file(s), that contain frequencies along with text describing them, are searched to find descriptions of who uses those frequencies.  If there is enough memory to do so descriptions for each frequency are sorted alphabetically.  The results of the search are written to another file that you specify

Intermodulation (IM) occurs whenever one or more radio frequencies are combined in a non-linear device. This produces sum and difference frequencies which are known as IM products.  The non-linear device may be a transmitter, a receiver, an isolator, a bad connector or any number of other items.  Sometimes the condition is desirable, as in the mixer stage of a superheterodyne receiver where signals are combined and selected to produce the familiar "Intermediate Frequencies" (I.F.).  Most of the time however, intermodulation is undesirable and steps must be taken to prevent or eliminate the conditions which give rise to intermodulation.  Such measures usually include the use of circulators and cavities to prevent signals from entering the final amplifier stages of transmitters, and the use of band-pass cavities at the inputs of receivers.  These factors are of special concern at mountain top repeater sites The number of receivers and transmitters at most repeater sites can vary anywhere between a dozen to a few hundred.  The number of intermodulation products which can be generated could be in the thousands A site manager may be able to exert total control over the conditions at a particular site, or only nominal influence over the activities of other users of the site.  In either case, a site manager faced with an intermodulation problem would be faced with the formidable problem of tracking down the one combination out of possibly tens of thousands which might be the source of the problem This program is designed to make that task easier.  Even though the number of intermodulation products is theoretically infinite, only a limited number of them are significant for a given set of receivers The products which we are mainly interested in are only those which will fall on or near a receiver frequency, and are of low enough order to be of significant amplitude

Logisym is a digital logic simulator, intended to assist you in understanding, debugging, and verifying, the operations of combinational and sequential digital logic circuits. The simulator utilizes a 'unit delay' model, and very accurately represents the operations of circuits built from the basic logic functions providing a timing diagram of the trace output, much like a 16 trace ocilloscope. The device library internal to logisym includes the following functions: AND, OR, NAND, NOR, (up to 8 input); XOR NOT, BUFFER, an RS flipflop (cross coupled NAND), a positive edge triggered D type flipflop, and a positive edge triggered JK flipflop. Up to 650 logic devices may be defined, and 16 points may be observed during a simulation. Logisym provides 26 different signals or 'clocks' to be used as inputs to the circuit(s) being simulated. These are: A variable frequency eight bit up/down counter, a variable frequency four bit ring counter, a variable rate random data generator, and eight bits of data controlled by way of the function keys on the keyboard. Fixed high and low logic levels are also available as tiepoints for unused inputs

These Keplerian elements contain orbit descriptions compatible for propagation with the Simplified General Perturbations (SGP) and SGP Version 4 (SGP4) orbit theories developed for use by the North American Aerospace Defense Command (NORAD) and United States Space Command (USSPACECOM TLEs have become an increasingly-popular source of orbital data.  This is due mainly to the fact that this format of data is available for nearly all Earth orbiting satellites.  As a result, the popular satellite tracking software packages such as STSPLUS and TRAKSAT use TLEs as their primary sources of input data along with the SGP4 orbit propagator TLE data is available for most Earth-orbiting satellites from several sources see Appendix F).  VEC2TLE is not intended to replace these as primary sources of TLE data.  Rather, its primary purpose is for circumstances in which this data may not be available in a timely fashion.  A prime example is the Space Transportation System (STS) where position and velocity state vectors may be the only orbital information available in near real time.  In the past, users of the tracking software had little choice but to wait (hours or days) until the TLE data was available following thruster firings that changed the Shuttle's orbit.  Often, the TLE data is out of date by the time it is received due to subsequent thruster firings.  It is this  situation that resulted in the creation of VEC2TLE.  The TLEs computed by VEC2TLE are fully compatible with SGP or SGP4 as true and accurate renditions of the orbit specified by the input state vectors
