  Propagation on HF has been horrible the last year or so -- far fewer stations 
showing up on my 30 meters HF map at:


than in years past.    However,  I have received some "real DX" stations here 
in Southern California.    The log snippet below reflects the entire day of 19 
Aug 2010 from 00:00 to 23:59,  as monitored off the air in Pasadena, CA with a 
Kenwood TS-50 and KAM TNC using the homebrew magnetic loop antenna described here:


This log reflects only the "classic" AX.25 packet activity, and does NOT 
include the newer APRS over PSK63 mode.     The log is produced by the AGW 
Monitor add-on for the AGW Packet Engine.  All times are local (to me in Los 
Angeles) Pacific Daylight Time.

Note that several stations are using  completely useless (for HF) digipeater 
paths that include variations of "WIDE".    (The few HF digipeaters around DO 
NOT respond to variations of WIDE. All these paths with "WIDE" do is make the 
packet longer while guaranteeing that you WON'T be digipeated, and reduce the 
probability of a successful decode.)
