RINGING FINITE IMPULSE RESPONSE FIR CW FILTERS, A PANADAPTOR, A REALLY GOOD
NOISE BLANKER AND THE READY ABILITY TO RUN DIGITAL MODES, PREFERABLY WITH A
1R0 PPM TCXO TEMPERATURE COMPENSATED CRYSTAL OSCILLATOR.  THE LATTER SHOULD
INCLUDE A STRAIGHTFORWARD MEANS OF CONNECTING TO A COMPUTER WITH A MINIMUM
OF ANGUISH AND HUM.  OF COURSE INTERFACES SUCH AS THOSE SOLD BY WEST
MOUNTAIN RADIO AND OTHERS ARE A GREAT HELP IN THIS RESPECT, BUT A RADIO
THAT DOES NOT NEED THEM IS EVEN BETTER.  FIR FILTERS ALLOW EXTREMELY NARROW
FILTERING WITH CONCOMITANT IMPROVEMENT IN S/N RATIO WITH NO RINGING EVEN AT
HIGH CW SPEEDS.  SINCE NOISE IS A MAJOR IMPEDIMENT IN DETECTING VERY WEAK

BY STRONG SIGNALS ON THE BAND.  FINALLY, A GOOD PANADAPTOR DOES WONDERS FOR
TELLING YOU IF THE BAND IS OPEN AND FOR FINDING THOSE ELUSIVE CONTACTS ON
THE MICROWAVE BANDS WHERE THE OTHER GUY OFTEN HAS NO IDEA WHAT FREQUENCY HE

RADIOS ARE SUMMARIZED IN TABLE 1.  AS YOU MIGHT EXPECT, THE NEWER RADIOS,
