This report is totally automated and is retrieved, modified for proper text and speech separately, then compiled, and uploaded at the top of the hour from my Shack Console on MY Intra-Shack LAN...(soon to be)once I get a radio again))... B-)



Thanks to Don WA6NBG, and the group at the 10th Annual Sustainable Expo in the Arcata Community Center on 10/14/17, which marks a new day in my history. That is the day I decided to become active again after 11 years, kind of like the solar cycle, where I was on packet here in Eureka, when there were still nodes around, where have all the relays gone, that is so critical, and must be resurrected in a more advanced way that makes the Internet look lame...

When I started in Packet Radio the Internet did not exist. Packet radio is the foundation that built the Internet in the first place, so it is up to us dedicated licensees to once again set the pace for how communications are done the right way...

This idea below I believe will revolutionize emergency communications for faster deployment of equipment and services where and when it is needed...

  1. Digital Emergency Communications: "Intra-Shack LAN" V.2.0...

    Today (10/15/17) I heard of a new IC from Maxim that is an Industrial CAN ("Control Area Network") Transceiver Low-Voltage, Low-Power chip for Industrial Factory Automation Communications, in real-time, the MAX3051 8-pin chip...

    After studying the datasheet I realized that this chip should be the center of how Emergency Command Centers are to be connected from operator consoles to the transmitters, using the "Intra-Shack LAN" V 2.0...

    I built the first "Intra-Shack LAN" in 1989 which was the control LAN for a Commodore 128 to track the space shuttle and get computed live coordinate data using Instatrack, then I would transmit that data to my guy "ART" (Antenna Rotor Terminal) which was a VIC-20 controlling my custom built AZ-EL rotor, and then my C=64 was connected to a PK-232 controlling my 2M/440 Yeasu Satellite Rig to make a 2-way packet contact with the Space Shuttle Columbia during the first SAREX mission, STS-35, contact #71 out of only a few hundred that made it, when 10k's tried as published in 73 magazine in 1990...

    The cool part about it was I could type any command on any console and it would only be heard by the computer that needed to hear it...!!!

    (At the time I was a Commodore Guru in the Bay Area and I created many machines for people using the Commodores as the complete control system, as it had everything you ever needed on one circuit board, I/O, powerful BASIC language (where I got my start) to control it, graphic display output, I made some pretty cool machines back then...)

    Today, I can get a full-fledged Windows-10 PC half the size of an iPhone with an addressable Arduino Coprocessor and I/O on board, with a 5" x 7" flat-panel, touch-screen (optional), for under $400, and it runs on a 5V 2A power source...!!! Combine that hardware with the most sophisticated software you can find if you like...??? But over the years I have found excellent free software that when combined together I can do anything you can imagine... But I'm not waiting on you... B-)

    MAX3051 +3.3V, 1Mbps, Low-Supply-Current CAN Transceiver
    (Industrial - Control Area Network)
    Differential-Output Slew Rate on the RS pin:
    Vrs = 0V (=< 1Mbps) 96 V/us
    Rrs = 25kOhm (=< 500kbps) 12.5 V/us
    Rrs = 100kOhm (=< 125kbps) 2.9 V/us
    Rrs = 200kOhm (=< 62.5kbps) 1.6 V/us

    Use the CAN twisted-pair wire ( good old Ma Bell punchdown twisted-pair works great... ), with various transmitters and assigned transmit frequencies based on hierarchy, and, use the current-loop twisted pair, that is immune to RF interference and is designed for industrial harsh noise environments, and critical control of machines' and factories' control reliably, to connect all the local Computer Consoles in the EC Room to the "Intra-Shack LAN" where that one twisted pair communicates with the radios in another location, out of range of interferences to the computers by the RF and visa-versa.

    Now locate the high-power equipment and transmitters very close to the antenna, and eliminate the feed line altogether if you can, in an area far from the digital equipment.

    Then use the same chip for a different purpose to dynamically control bit-rate based on conditions for optimum speed using the feedback from analyzing the received signal parameters on the handshake ACK, to dynamically adjust for maximum throughput, with a resistance to ground signal controlled by a digital-pot for precise control with memory, to control the slew-rate, in one low-power chip per each Computer Console and Transmitters!

    And you can use whatever protocol you like for LANcom, but AX-25 comes to mind first, just at a faster pace than it was before, and with dynamically optimized throughput control based on real-time conditions, for maximum efficiency in time of need...

    Also use a hybrid of AX-25 protocol with hierarchical channel switching based on the other agencies emergency channels, which can be cross-banded, multiplexed, or cross-linked, under software control, and using the Manchester Code Sequence so the bit-rate is self-synchronizing so that maximum throughput is dynamically adjusted in real-time, full-duplex control...

    If you follow Astronomy at all, DUH, that's a dumb statement, you may know of how they dramatically increased the focus of ground-based telescopes by using a computer-controlled conformable mirror to match the distortion in the atmosphere dynamically in real-time. This corrects the distortion in the atmosphere to render a clear image like never before.

    The "Intra-Shack LAN" works the same way... The feedback from the received signal of an EC Room "TXmsg" is analyzed and dynamically controls the speed at which the data is transmitted in real-time to self-optimize for maximum possible throughput in the least amount of time, to make room for other critical traffic...

    And never worry about cross-talk, bleed-over, or any other electrical interferences again...

    The "Intra-Shack LAN"... ISLAN is your LAN... B-)

    Update: 11/29/2017...

    I have purchased 2 pair of TX/RX 433MHz radio remote relay controls and I am building the prototype out of these for test of concept since 1 experiment is worth a 1000 expert opinions... B-)

  2. The Strategic Defense Initiative (SDI) - "Star Wars"... (revealed)

    A number of these concepts were tested through the late 1980's, and follow-on efforts and spin-offs continue to this day...
    Strategic Defense Initiative

    Alexa speaks about SDI... 1m29s

    I met my best friend of 30 years in 1984, David G. Hunt, KB6JAW, now silent-key since 12/14/15, and he taught me everything I know about Radio, we met on the job site as we were Journeyman Electricians when we met in the Bay Area. We hit it off immediately and started working together with many high-tech and government firms installing Electrical Systems to handle all the latest technology and we worked very closely with the engineers to build what they created, that had never been done before, and so we had to build systems to handle unforeseen conditions that were not known, and then be able to modify it at a moments notice to accommodate the changes to the system to reach the goal...

    The best story goes first: The last project I worked on for SDI was the project where they took an old antenna testing building from WWII which was on the very edge of the marsh that led into the S.F. Bay at Moffet Field in Mountain View, CA, and they would build HF antennas on a platform that was on a small railroad track that they would use to pull out into the marsh with a cable and pulley, so they could test the antennas without being in the field-strength, and then pull it back in to make adjustments, and then pull it out there over and over again until they got it right.

    There was a large opening on the south side of the buildings tower facing the Bay where the antenna could be pulled inside of the building fully erect to work on it. The building had not been visited in over 40 years and just sat there getting infested with all kinds of creatures, until we got there to start the most important part of the SDI project.

    That building also had a one-bay garage facing north that could hold a semi-truck and trailer inside for shipping antennas back then. This building was turned into an extremely powerful ground-based particle-beam and flight control center capable of beaming high-energy particles, coherent like a laser, to a geostationary satellite mirror gimbal to point to any space or land based targets hemispherically, in 1988!

    The shipping bay held the particle beam generator that was the size of a city bus, and the power we brought in to fire it up was tapped directly from the sub-station that fed all of NASA and Moffet Field and fed directly to a huge transformer that was flown in by helicopter that was also the size of a city bus, dropped on the special pad outside the building, that would boost the voltage to mega-volts at and mega-amps to driver the particle-beam.

    In the building was a highly polished surface mirror that reflected the beam at a right angle to point the beam horizontally out the back-side of the building down the tracks that now holds a gimbaled highly polished mirror instead of an antenna like 40 years ago, that points the beam to the geostationary satellite, which gimbals to a target anywhere on this side of the earth...

    The flight control center was behind the first right angle mirror in the middle of the building that was very hard to get to. But unfortunately I was kicked off the project because they found out I am Canadian and deemed me a security risk, but not before I had a chance to study all the blueprints, because you can't do shit without electricity... B-)

    When they finally tested the particle-beam for the first time, the whole city dropped in voltage to critical levels... ( I had no clue what they hit, but I'm sure it was vaporized! )

    David and I also built 2 Tempest Rooms for "The Customer" (the Air Force) at Moffet Field, and that was such a profound project to work on... David and I were the only humans to ever enter a large room when it was finished, which was TOP SECRET in the middle of a huge building with 100's of offices, that was a totally automated and robotic missile guidance control circuit board assembly factory that could create a board from scratch with just the raw components to completion and thoroughly tested for insertion in a missile in less than 15 minutes... The complete supply chain was also totally robotisized so that no human could ever reverse-engineer what the robots made, insuring top security of the guidance system, but, David and I had to study the complete system to effect repairs that needed to be done before they could press it into service...

    More stories to come...

  3. The perfect motors for light-duty AZ-EL positioning:

    Gear Motors with guaranteed 20lb. torque for working low-orbit satellites: Onlyfire Universal Grill Barbecue Battery Replacement Cordless Rotisserie Motor 3 volt 1 Watt On/Off Switch

    • Cordless operation provides the freedom to rotisserie without electricity.
    • Operates for 36 hours on 2 "D" cell batteries. (Batteries not included).
    • 20 lb. load capacity allows for cooking of small to medium loads.
    • Fits standard 3'' motor mounts & standard 5/16'' square drive rotisserie spit rods.
    • Anti-Backlash Gear Train Provides Reliable, Smooth Operation.
    • Professional quality components designed for extended duty usage.

    A 3.3V tiny85 controller such as a digispark or others can run on the 2 D-cells for a rotisserie motor, and 2 - H-bridge motor driver chips that can drive a 200ma motor load without a heatsink, one for each motor (which only draw 100-150ma each rotisserie motor at full-torque), plus 2 - 100kOhm pots on the end of each shaft for positive realtime monitoring of the angle being selected to offer closed-loop feedback for precise control of positioning, and with PWM to the motors the tracking is a continuous smooth motion of both axis to lock on the signal to fine-tune the track pre-mapped by the calculations of the up coming pass, in the tiny85 processor...

    Which can automate sat-pass positioning for automated gateway actions... (WHO would do such a thing(?)) B-)

  4. ... (more later) But in the meantime, I have no rigs that work anymore and I'm looking for an old 2M base rig if I can find one so I can get on packet again and revive the communication systems in a new way...
