    I get a nice Codan 8525 in good condition. I want to use this transceiver on the hambands.

    Me was told this radio was used in the army 1998.

    How can i program (eprom) to use this on the hambands?

    EEPROM 4.1-4.3 have these specs:
    Your transceiver has a capacity of 600 channels, these cover:
    • transmit frequency range 2 MHz to 24 MHz
    • receive frequency range 0.25 MHz to 30 MHz.
    A maximum of 501 transmit and receive channels can be
    pre-programmed in the factory, or by an authorised Codan
    dealer. You, as a user, can program the remaining 99
    channels from the front panel as P-channels.
    That means you can work many bands already. I found the manual here:

    I know this is an old post, but does anyone have the programming info or an EPROM hex dump for a Codan 8525A to put it on the ham bands?
    It will be a lot easier than reverse engineering it, or modifying it to take an Arduino, which is my other option, assuming I can figure it all out.

    I have the 2 LED digit front panel on mine, not like shown above, but this one.....

    Well, I actually got a reply!!!
    But, unfortunately, no help is available as it is too old.
    Oh well, back to hacking :)

    Contact the ALE people in ham radio. There’s a good chance they know some things about these radios I think Bonnie krystal heads that up

    Just google around and you’ll find them

    Thanks, but Bonnie has no info either. It is looking more like I will have to work it out myself :)
