Re: Re: 147.585 during Leonids



Good Evening Tim et al:  The leonid coordinated frequency 147.585 is also
used as a DX packet cluster station in central SC.  I alternate between
145.79 and 147.585 (depending on local traffic on 147.585) with my KLM sat
antennas pointed NE, N, NW and W from SC.  I saw no visuals nor did I get
any screen prints last night.  I thought the Nov/QST article was very
helpful in setting up. Things were dead at my QTH.  My power out was about
150watts with my antennas elevated 20 degrees.  I will try again Thursday
evening.  Good luck to all the meteor scatter/aprs folks.  Al
