On 15 January 2006 from 0930-1009Z (referenced to WWV/WWVH on 10.00000MHz),
I recorded all signals heard on the frequencies of 144.200MHz USB (2M
Amateur Radio band), 50.069MHz USB (6M Amateur Radio band) and 55.240MHz
(TV CH2 video, -offset). The 6M/TV video signals were monitored on an Icom
IC-756pro transceiver using the "dual watch" function. On the 6M band the
frequency of 50.069MHz USB was chosen with a 3KHz bandwidth, to split the
difference in frequency between the K6FV (Woodside, CA) and WA7X (Fairview,
UT) beacons which appeared to be probable targets, based on their locations
and decent power output. The 55.240MHz TV2 video offset is free of
groundwave propagated signals at my location. The full recording provides
a background meteor level reference prior to re-entry. All of the "pings"
prior to the re-entry period were from 55.240MHz video carriers. No
signals were noted on 144.200MHz, and that recording was not published.
Starting at 0957.07Z I received the morse code letter C, presumed to be the
part of the CM97 grid square locator sent from the K6FV beacon. No other
6M amateur radio beacons were noted. Starting at 0957.15Z the TV2 video
carriers peaked suddenly (and quite strong). The signals slowly decayed
over time and there was considerable fading and some doppler shift on the
carriers. I do not have high accuracy video carrier references, so I can
not identify what location these carriers originate from.
