    Paul,
    I'm only using 88.1in my experiment for convenience and in my area it is unused. The closest tx is 150 miles away.
    If I produce these commercially I will use the 400 mhz commercial band with a DTMF tx and rx .
    With DTMF a receiver will not accept reception without a specific...

    Sometimes you can't see the woods because of the forest.
    I burn the weeds and could see the big picture clearly !! Haha :)...

    Got it cleaned up and on a board, plus connected to the pickup.
    This is pretty small already and a surface mount device will be the size of a dime....

    The FCC allows us to use Specific frequencies in the F.M. broadcast band.I choose 88.1mhz for simplicity in the project. My tx power is low enough to pass the regulations, plus it's an unused frequency.
    Now I can use products that are readily available for the project.
    My only problem was...

    Great input Vance.
    Never thought of the analog guys !!
    I can devise the receiver to put out a voltage for an analog tach and pulses for digital tachs.
    Positive and negative input always helps me see in different perspectives, thank you for your input.
    With my limited technical...

    Once I'm finished with the design I am going to have them commercially produced to accommodate different models of gyros. Some count 108, some count 4 and some count 1 Per Rev.
    Thanks for noticing. I felt this would have gotten a much larger response because none of the engineers or geniuses came...

    started a topic Wireless Rotor tach.

    Wireless Rotor tach.

    Decided to build a wireless rotor tach.

    This is just dead bugged on the wire for now and will be put on a PCB board once the design is complete.

    This is a crystal controlled F.M. transmitter, so the frequency is very stable and Yes, I can modulate a crystal in F.M.
