These are exciting times!  The official start of Cycle 24 was announced on January 2008 when a magnetically reversed sunspot was spotted.  Although I do recall reading about one being spotted in August 2007.  This is usually an indication that the new cycle is about to begin.  This solar cycle is being projected by scientists as one of the best since the exceptional cycle that peaked in 1957.  I myself am looking forward to Cycle 24 providing 10 meter openings that will generate worldwide propagation using modest antenna systems and only a few watts of power to the transmitting antenna.

The 15 WPM CW Beacon Text is as follows:
10 second delay 5 second keydown vvv vvv de na5ss/b dm65qg na5ss/b dm65qg na5ss/b dm65qg 1 watt

BEACON is currently OFF-THE-AIR

The setup:

A double sided PC Board was used as a groundplane.  A single sided pc board was cut into chips to accomidate interconnect landing zones.  They were epoxied into place before the components were soldered into place.

Assembled through the buffer stage.
 All three stages.

Transmitter: Homebrew QRP transmitter design from ARRL Solid State Design for the Radio Amateur by Wes Hayward, W7ZOI and Doug DeMaw, W1FB 1977.  
Beacon text:
    The CW beacon text is being generated by a "Freakin' Beacon" available at Expanded Spectrum System.
Antenna:  Delta Loop at 6 meters high.
Power:  Completely solar powered.  A 50 watt GE Solar Panel and a charge controller connected to a Deep Cycle Marine battery.  This also provides lighting in the storage shed where the system is located.

Hard to find parts for building the 6 Meter beacon were purchased from Dan's ~ Small Parts and Kits.
The crystal was purchased from International Crystal Manufacturing.
The double sided PC board and enclosure were purchased from Radio Shack.

Total cost for the project was under $80.  Plus it's a great learning experience.
