"In common with other types of radio signal propagation, meteor scatter is frequency-dependent."... For the commercial systems that use the underdense trails, the maximum frequency is somewhat lower, and the communications are often limited to a maximum frequency of about 50 MHz. Typically most operation takes place between about 40 and 50 MHz, although operation on lower frequencies would be possible. Below 30 MHz interference levels rise as a result of the increased number of signals resulting from ionospheric propagation."

Not likely at 27 MHz but have to be there if / when it happens.
6 meters (50-54 Mhz) and 2 meters (143-148 Mhz) operators can experience the scatter effect most mornings in and around Sunrise with distances ranging from several hundred miles to as high as 1000 miles on 6 meters.
However, you have got to be there to work it. Good antennas with Horizontal polarity and quick transmissions are almost a must.

PS: Aurora scatter and Meteor Scatter are two totally different propagation effects by the way.

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
  • @ AudioShockwav:
    Wes, it's better if you start a thread on the main forum, more people are going to see your question.
  • @ heartbreaker3473:
    Okay, sorry, will put in a forum
  • @ heartbreaker3473:
    I put it in the general disscution help area and started a new thread. Thank you for letting me know.
