    "content": "Good Morning Patrick,\nI couldn't help but reply to this...  I can't believe that we have astronauts that can't use a D700 and us regular folk that can.\n\nYou could use the PMs to make life easier on the ISS.  PM 1 could be setup for earth-space communications when the astronauts have time to talk with us Earth-bound people.  Then you could have PM 2 setup for packet, PM 3 setup for crossband repeat, PM 4 setup for APRS digi, PM 5 setup for...\n\nThat would completely negate the thought process of having to change the settings and frequencies each time.  I have my D700 setup similarly so when I go to PM 1 the radio reverts to a specific channel on each side, turns the TNC on and into APRS mode, and selects all the proper settings in the menus.  I set this up via the software many months ago and everything works great.  I no longer have to continuously swap my settings when I get out of the vehicle because going to PM 2 does my \"Out of Vehicle\" settings.  PM 3 is setup for crossband repeat so when I get out of the vehicle to go hike it is already setup to go to my local repeater and a simplex frequency and I'm ready to go.  This would seem to be the most efficient use of what that radio has to offer.\n\n73s,\nEric W4OTN\n\n\n>Hello Patrick,\n>Thank you very much for your comments on the Marex\n>Project proposal. We are always interested in hearing\n>pros and cons for all projects and welcome\n>constructive input.\n>\n>We believe in the slogan Keep It Simple (KIS). \n>When it comes to projects we sometimes Dumb them down\n>to make it easier for the ISS crew.  Sure these guys\n>are very smart, but they do not have time to find and\n>read the manuals for the 50+ radio, etc on ISS.\n>\n>Examples:\n>On Mir Marex flew the Kenwood TM-D7A.  This radio was\n>used to run the SSTV project and became the primary\n>Voice link.  This and other Kenwood’s have a row of\n>Program Mode buttons (I call them function buttons). \n>They allow you to save different modes of operation\n>and can be very complicated.  After reading the\n>manuals several times and testing the PM buttons, we\n>decided it would be too complicated for the crew to\n>understand these buttons, so we disabled them. \n>Actually I programmed all of the PM buttons to do just\n>the same two items, Go To Channel #1 and Set Transmit\n>Power to Low.  That way if the crew hit a PM button\n>they did not have to worry about rebooting the radio\n>into a different configuration.\n>\n>Slow Scan TV:\n>On ISS, Silicon Pixels custom designed software just\n>for ISS.  We chose them because they had the best\n>solution at the time for SSTV. However, there off the\n>shelf version of software “CPIX” wold have been too\n>complicated for the crew to understand.  There were\n>many great features that the ISS crew just would not\n>have time to learn.  The Silicon Pixels team developed\n>a Dumbed down version of software that had just the\n>basic features that the ISS crew would need.  We tried\n>to make it as simple as possibly by deliberately\n>deleting features that were not needed.  And we made\n>the Buttons big so the crew could hit them easily\n>while floating in Zero-G.\n>\n>For the new Dual band Radio proposal that Marex has\n>put forward, I wanted to again try to Keep it simple. \n>I wanted to avoid the problems associated with a true\n>Dual-Band radio, such as two volume controls, two\n>squelches and a Band switch etc. The ISS crews have\n>been having problems with figuring out a “Function\n>Button” radio verses a Channel knob radio.  I wanted\n>to go back to 1 channel knob, 1 squelch and 1 volume\n>control.\n>The Icom ID-800 seems to meet most of our requirements\n>for Keeping it Simple.  Once we program the radio on\n>the ground the ISS crew only needs to know the\n>following controls:\n>\n>Power Switch\n>Channel Knob\n>Volume Knob\n>Squelch knob.\n> \n>Instructions for changing frequencies, bands or Voice\n>Modes will be as follows.\n>Turn Channel knob to channel XYZ.\n>\n>Turning on Packet will be as simple as:\n>Turn Channel knob to channel XYZ.\n>Push power button on TNC and look for Green LED on\n>TNC.\n>\n>Believe me, it’s a lot simpler to use than what we\n>currently have in space.\n>\n>Digital Voice Modes:\n>The ID-800 does support digital voce modes and all\n>normal Analogue FM modes.  Since our goal is to reach\n>as many people as possible, the primary mode will be\n>Analog FM voice.  The digital modes wold most likely\n>be used for semi-private family communications, etc.\n>\n>Deliver Time Frame:\n>This project is not approved at this time.  We only\n>have approval to continue with the Kantronics KPC-9612\n>Modem side the project.  Back in the Old Mir days, the\n>longest it took me to Pitch a theory to Switch on was\n>15 months (SSTV Mir, Pitch theory September 1997,\n>Switch on December 1998).  With ISS, it takes much\n>longer.  I am tying to use a radio that will still be\n>in production when we go into space.\n>\n>The next project proposal demonstration is tentatively\n>planned for Moscow in Late 2007 or early 2008.  \n>\n>Thanks for your input and support.\n>\n>Miles\n>\n>www.marexmg.org\n>\n>\n>\n>--- Patrick McGrane <[email protected]> wrote:\n>\n>> Hi miles- de patrick n2oeq- nice to see you thinking\n>> of the future.
