(meteorobs) Meteors heard on Digital & analogue TV

[Michael Boschat]

Morning:


Well, as we approach the Daylight Arietids/Zeta Persieds, I took a couple hours from 4am to 6am messing with my

Icom R-20 radio to find some backup frequencies, as I am monitoring 82.3101 MHz supposed to be Ch. 6 Digital carrier.


I have to use a notch filter to reduce other noise about. Here is what I use:


Antenna Direction: Horizontally polarized with lobes in E-W plane, elev 10 deg
Filter  : high-Q (Q at least 300) bandpass filter between antenna &  receiver.
Listening Mode: CW



 So, my results: VC = Video Carrier, DC = digital carrier


1)   Ch.2  - VC = 55.25 MHz - Nothing heard

                - DC = 54.31 MHz - Nothing heard


2)   Ch.3  - VC = 61.25 MHz - tone heard only

               - DC = 60.310 MHz - nothing heard


3)  Ch.4  - VC = 67.25 MHz  - strong tone and meteors heard

              - DC = 66.310 MHz - nothing heard.


4)  Ch.5  - VC = 77.25 MHz - tone and couple meteor heard

              - DC = 77.310 MHz - meteor heard


5)  Ch.6 - VC - 83.25 MHz - strong tone and meteor heard

                   - 83.24 MHz - meteors heard

            - DC = 82.3101 MHz - many returns heard!


from Ch.7 to 13 just too high, I do get a very strong tone Ch. 8 at 180.310!


So at least I have back up frequencies to use. I'll keep checking during meteor showers

on lower frequencies.


 As I type this I am hearing meteors on my regular 82.3101 MHz ...
