40 METER QRP BEACON TEST : FEB 10-11

I will be running an experimental QRP beacon on 40 meters again starting
Saturday evening Feb 10 (EST) through Sunday afternoon Feb 11.

However...

This time I will be testing an automatic power sequencer which will permit
the beacon to automagically set itself to operate a several different power
levels during each hour. This will provide many more chances to copy the
beacon at extremely low power levels throughout the day.

Time : I am aiming to have it on by 7 PM EST Saturday 2/10 and keep it
       going until at least 5 PM EST Sunday afternoon.
       
Location : Newtown Square PA FM29hx (about 15 miles west of Philadelphia)

Antenna : 40 meter inverted vee @ 50' in a north/south plane.
          Fed with 125' 9913

Frequency: 7021.0 KHz

Power schedule: The power will be changed during each hour according
                 to the following schedule:

       minutes past
         the hour - power level-
       :00 - :01 2000 mW (high power) spotting beacon
       :01 - :15 200 mW
       :15 - :16 2000 mW (high power) spotting beacon
       :16 - :30 20 mW
       :30 - :31 2000 mW (high power) spotting beacon
       :31 - :45 2 mW
       :45 - :46 2000 mW (high power) spotting beacon
       :46 - :00 200 uW !!

In other words... The beacon will run at 4 (actually 5) different power
levels each and every hour. Every 15 minutes on the quarter hour, the
beacon will run for 1 minute at 2 watts output for spotting purposes then
run at the specified power level for the next 14 minutes.

Power change times should be pretty accurate (set your clock) however,
the change will not occur until the message in progress completes, that
is, it will not change power in the middle of a message.

A different codeword will be used at each of the 5 power levels.

Message format : VVV VVV VVV xx mW <4_letter_codeword> DE WA3NNA/B QRP
                 Sent at 13 WPM.

Take a listen and see if you can hear it.

All reception reports will be appreciated. Send them as soon as you hear
something. I will be checking e-mail on and off all weekend.
