[PPRAANet] 146.52 Hunt in Progress

[Bob K0NR - email list]

Paul,

Thanks for going on the hunt. Good luck.

Here's what I have found by monitoring the signal from Monument:

  * Received the signal with my 1200 baud packet station and it does not
    decode anything. The signal does NOT sound like amateur packet.
  * Received the signal with my P25 scanner and was unable to decode any
    audio. To my ear, the signal does sound a lot like P25 digital but
    that is only speculation.
  * Received the signal with my Yaesu C4FM transceiver and was unable to
    decode anything. It does not sound anything like C4FM / Fusion.
  * Monitored broad sections of spectrum (150 to 1000 MHz) looking for a
    signal that comes up when the signal is present on 146.52 MHz. No
    luck at all.
  * Received beam headings from a number of hams...kind of points in the
    very general direction of Cheyenne Mountain from Colorado Springs
    and Monument but no real conclusion is possible from these reports.
    Paul's on the ground DFing will tell us a lot more.
  * The repetition of the signal seems to decrease in the evening hours
    (like only one per hour), increases in the morning (once every 5
    minutes?).
  * I did hear a short snippet of audio morse code mixed in with the
    digital signal, several times now. Very short, heard only a couple
    of characters (think I heard K and N).
