    Hello. I own a Yaesu FRG 7 receiver and have read that it's possible to add a digital frequency readout.

    Can anyone tell me if there is a kit available for purchase which I can then build and fit, including all components and instructions. Or, if not, what parts are required, where to buy them, and where to get construction and fitting details.:headbang

    I am able to build electronics kits no problem, and own a soldering iron, multimeter, etc. but do not have more sophisticated equipment such as a signal generator, oscilloscope etc, so if these would be required I may as well give up before I begin.:thumbdown:

    I would ideally have liked to build the display into a separate case which can sit on the receiver top, connected by means of a cable perhaps to a socket on the rear of the receiver. Would this be a possiblity, or would any circuitry have to be contained within the existing cabinet?:confused:

    Any advice welcome.(y)

    Freq counter kit

    There are lots of freq counter kits for QRP I saw some from N3ZI on ebay for around $25 or less. They use a LCD and a pre-programmed microcontroller. I don't think they are backlighted.

    N3ZI FREQUENCY COUNTER / DIGITAL DIAL SIMPLE KIT w/ PCB - eBay (item 130340941621 end time Nov-29-09 11:01:40 PST)

    AADE makes 4 LCD based Almost All Digital Electronics
    Norcal qrp club has some nice kits NorCal QRP Club - FCC-1 Frequency Counter Controller

    LED's are more my preference

    Here is a really neat receiver kit that has a LED counter sub assembly. Cool site.
