    dgrayone got a reaction from abelpratt in FM Micromitter only transmitting 8M   
    Hi all,

    I'm new here.
    I have just assembled a FM Micromitter (Miniature FM transmitter).

    http://www.siliconchip.com.au/cms/A_102010/article.html

    Construction went well with very few re soldered points (put a couple of things in the wrong way round, but hey I'm learning).

    When I went to do the testing and adjustment it says that I should be reading 5v between TP GND and pin 8 of IC1 but I only get a reading of 2.5v.

    Can anyone tell me why this might be and what the consequences of this might be.

    It DOES transmitt (I am currently transmitting on 88.9) but I loose the signal after approx 8M from the antenna.  Is this related to my drop it voltage measured against what it should be?

    Should I trim my antenna to a specific length?

    Any comments or suggestions would be much appreciated.

    Regards

    David ???
