Digital Voice Links

Beginning to delve into the realm of the digital voice modes.

Below are my links of interest...  so that I can find them again when I actually have the time to work on it!

Repeater Builder USB-RIM


Repeater Builder USB-RIM Lite

    RIM-RC210/RLC: Schematic
    Special Limited Time Price - $50 
    This version is customized to be plug-and-play with the ARCOM RC-210 repeater controller. It is also compatable with RLC controllers from Audio Test Solutions (Formerly Link Communictaions). Simply plug the module onto an unused controller port, configure the controller and AllStar config files, and you are ready to explore the world of AllStar linking.
    **Specific connection instructions will be available soon.**

    RIM-Maxtrac-RM: Schematic
    Special Limited Time Price - $60 
    This product is VERY similar to the RIM-Maxtrac. The RM stands for Repeater Maker. The RM adds a second 16 pin module to connect to a second receive only radio. This allows for one radio to be the receiver and the other to be the transmitter in a repeater type setup. The RM version does NOT support channel steering.
  • All of the new Lite version products still inclue the missing pulse detector circuitry to avoid stuck PTT lines. By default, the heartbeat and PTT outputs are configured to allow the missing pulse detector to automatically disable the PTT line in the event of a stuck PTT due to USB PC communications failure.

  • All of these new boards offer an optional serial EEPROM that can be used to store radio/repeater settings.*

  • Courteous and friendly customer service. While product documentation is currently being written, the user's manuals for these products will follow in the same lines as the rest of the RB products in being straight forward and thorough.
  • * Software implementation dependant

    Creating a Dual Boot Windows 7 / MS-DOS 7.1 System

    Programming the older radios that absolutely need DOS AND a true serial port can be a real pain in the ass.  Although DosBox is wonderful and can work with the USB to serial adapters much of the time, sometimes you just can't go that route.  After spending the better part of two days (!) going thru the motions using GRUB, PLOP, various bootable media, I thankfully ran across the following article which is working for me.  Perhaps it will help you, too.

      TweakhomePC : Install Dual-Boot of MS-DOS 7.10 (FAT32) on Windows 7 computer (Win7 installed first)

    Many thanks to TweakhomePC for ending my misery!

    146.460 Simplex 100Hz tone.

    Node Status

    Graphical Connection List

    Equipment:  Node Radio, Motorola GM300@8 watts, approx 50 ft. LMR-400 to roof mounted 1/4 over 5/8 homebrew J-Pole at approx 1400 ft elevation.




    All Star Node 42255

    East TN All Star HUB

    HUB Status

    Graphical Connection List




    Note:  Often Nodes 41594 (WB4IVB - 442.900+ 100Hz Corbin / 442.350+ 100Hz Black Mnt. Harlan Co. KY)  and 29891 (KE4JGJ - 147.180 + 74.4Hz London KY) will be connected.

    You may also see (3)355800 connected.  This is Echolink Conference server *DODROPIN* which hosts many nets throughout the week.  Being as it is on the Echolink network and not the All Star Network it will not pass any info on the Graphical List and only it's number on the Status pages.

    Please connect to the HUB If you cant to connect to the group.  You can check the connection status of All Star Node 42255 beforehand if you want to know who is linked up.

    Updates

    Middlesboro -

    443.950 is off the air until I can replace the antenna.  It appears to have slowly degraded over the past 2 years.  The desense issue has now been eliminated up to the jumper or the repeater antenna.  Info gleaned from the web would indicate that the Diamond 718 antennas can't handle the mountaintop locations for - of all reasons - heavy moisture condensation at altitude.  Go figure.

    Caryville -

    I have decided to go ahead and coordinate the 444.675 (+ offset, 100.0 Tone)  Seems like much ado over nothing considering it's low profile and lack of coverage, but I might as well.

    It is IRLP connected and is parked on the East Coast Reflector 9050 mostly during the day.  At night, it may end up on either the 9109 Alaska Channel or 9070 Alaska Reflector.  Or on 9050.  Feel free to use it.
    73 disconnects while simply inputting the IRLP node or reflector number will connect.
    Just be sure to wait 30=45 seconds before transmitting when you first arrive so as not to inadvertently interrupt a QSO.  If you connect up with something just disconnect after you are through.

    Allstar Node 41538 is running on 146.460 (100.0 Tone.)  I am planning to mount the antenna about 20 feet higher and go with a higher gain antenna - but not too high a gain - we are in the mountains, after all. This node may or may not be connected to an IRLP bridge, another Allstar or Echolink node, or simply idle.  *70 will give you the node status.  If it is in repeat mode, you're set.  If not, *73 will disconnect all.  *3XXXX (xxxx=allstar node number) will connect you to the node number you input.  If you want to use Echolink, shoot me an email.  It's a bit more tricky.

    Future plans -

    Once 950 is back on and working, I will connect it to the Allstar Linking Network.  Why...?  Because we can!!!
