HAWKESBURY – Les radioamateurs du Service radioamateur en situation d’urgence de Prescott et Russell (ARES ou Amateur radio emergency service) étaient fidèles au poste les 26 et 27 juin derniers dans le cadre de l’activité Field Day (journée champêtre).

This is the small interface board I threw together to connect a Satoshi DV Node Adapter based repeater to an Icom ID-RP2C D-Star controller. It’s built around a 74AC541 Line Driver Buffer integrated circuit with an inverter for the RE/COS signal from the DV Node Adapter.

    Wow, is that what I sound like?
    I did say, “It’s working quite well” a number of times didn’t I??
    Oh well… you get the message!

    The schematic is a work in progress, not that it’s a complex circuit… it’s just that I don’t have any software suitable to do the job properly.

    Looks pretty neat Michael. Good Job! Those Icom service manuals are torture aren’t they? 🙂 I made use of them when I built my TX/RX daughterboard mod for the RF stack modules. I used the free version of Eagle Cad to do my schematic capture and board layout. A little learning curve, but extremely flexible. Are you planning to publish the schematics? If so, I’d be happy to draw it out for you and looks like something I might like to play with.

    Hi Eric, thanks for the comment. I have use KiCad to draw up a schematic and I am almost “real soon now” ready to release an implementation document that will help those wishing to replicate what I have done. I’ll put a link to it here (and on my other related YouTube videos, and on the related Yahoo Groups.
    Stay tuned!!

    As I cannot post a direct link… Google “vk5rex” and “squarespace” to find the VK5REX web page. In the downloads section you will find the info you need.
