    Selling a microprocessor driven accessory which - in conjunction with an eBay purchased DDS unit will let the user upgrade any Ten-Tec Omni A,B,C or D radio with dual VFO capabilities. It’s powered by the powerful new PIC16F18344 processor which requires no crystal and which runs at 32 Mhz.

    Furthermore, this unit can be used to upgrade many solid state radio (like the Drake TR-7) that use a 5.0 - 5.5 Mhz PTO/VFO. The DDS VFO may be installed within the radio (some modifications are required along with moderate construction skills) or in a stand alone box (truly plug n' play) and then connected to the radio via the rear mounted jacks (see pictures).

    Either way, it works very well.

    Detailed installation instructions are included on my website, links shown below:


    Installed in an aluminum box (plug ‘n play):

    Installed within an Omni (illustrative):

    Installed within a Triton (illustrative):

    Installed within a Century 21 (illustrative):

    Stand alone with a Drake TR-7 (illustrative):


    Plug ‘n Play unit (requires one minor wiring change within the Omni / Corsair / Delta / Triton (etc): $130 - 1 available.

    Wired and tested board (w/DDS CHIP): $85 - 3 available

    Partially populated boards (no DDS CHIP): $45 - 3 available

    Unpopulated board with programmed microprocessor (no DDS CHIP): $30 - 4 available

    Note: Modest construction skills are required to install this unit WITHIN a target radio. Connecting the Plug ‘n Play external unit is so simple that even a caveman could do it.

    Priority Mail ($8.50) shipping to the CONUS only (no California, and no international)

    Feel free to call me on 610-779-4363 if anyone would like to discuss.

    Well, I'll tell you. For one thing, I have been burned on the shipping charges to those 'out of the way' places where UPS (and others) levy some kind of surcharge. The other reason is personal. I just won't ship anything there any more.
