ACCOMPANYING PHOTO.  THE SKYPIS FUNCTION IS MAINLY TO PROVIDE POWER
AMPLIFICATION AND HARMONIC FILTERING.  AFTER BUILDING THE KIT, WE FOUND THE

USE THIS COMPUTER TRANSMITTER?  ONE OBVIOUS APPLICATION IS AS A WEAK SIGNAL
PROPAGATION REPORTER WSPR BEACON.  IT ALLOWS THIS 1 W TRANSMITTER TO BE
HEARD AROUND THE WORLD BY STATIONS THAT REPORT THEIR RESULTS TO A WEB
DATABASE AND MAPPING SERVICE WSPRNET. ORG.  ALL YOU NEED IS A DIPOLE OR
OTHER 40 METER ANTENNA.  THE SKYPI ALSO SUPPORTS RTTY AND CW.  RTTY IS SENT
ONE COMMAND LINE AT A TIME.  WITH THAT LIMITATION, ITS PROBABLY MOST USEFUL
AS A BEACON BUT A GRAPHICAL FRONT END PROGRAM IS IN DEVELOPMENT THAT
INCLUDES MEMORIES FOR CW AND RTTY MESSAGES.  THE SKYPIS CW MODE TRANSMITS
ACCORDING TO A KEYING INPUT FROM ANY MORSE KEY.  AN OPTIONAL RECEIVER PORT
ALLOWS FULL BREAK IN TWO WAY QSOS ON CW WITH A SEPARATE RECEIVER.  THE PORT
IS ALWAYS ACTIVE, BUT IT IS LIMITED TO A SAFE LEVEL FOR ANY 40 METER
RECEIVER YOU WOULD LIKE TO ATTACH.  AS WE WERE FINISHING THIS REVIEW,
RADWAV ANNOUNCED A COMPANION RECEIVER, THE SKYPIRX, TO CONVERT THE SKYPI 40
INTO A TRANSCEIVER.  THE MANUAL INCLUDES QUITE A BIT OF INFORMATION ABOUT
