HF RECEIVE PREAMPLIFIER ACTUALLY WILL MAKE THE SITUATION WORSE BECAUSE THE
RECEIVER WITH A HIGH GAIN PREAMP IS MORE LIKELY TO OVERLOAD AND CAUSE
SPURIOUS SIGNALS TO BE GENERATED IN THE RECEIVER.  IT WASNT ALWAYS THIS
WAY.  UNTIL THE 1960S, RECEIVER PREAMPS OR PRESELECTORS WERE QUITE POPULAR.
THEY GENERALLY ALSO INCLUDED TUNED STAGES THAT REDUCED RECEIVED IMAGES, A
PROBLEM ABOVE 20 METERS WITH MOST SINGLE CONVERSION RECEIVERS USING A 455
KHZ INTERMEDIATE FREQUENCY IF, A COMMON DESIGN IN THE VACUUM TUBE DAYS.
<  QST DE W1AW  =
MODERN RECEIVERS GENERALLY HAVE MULTIPLE CONVERSIONS WITH THE FIRST IN THE
HF OR VHF RANGE SO IMAGES ARENT A PROBLEM.  IN VERY QUIET CONDITIONS, EVEN
SOME MODERN RECEIVERS CAN BENEFIT FROM A LOW NOISE PREAMP ON 10 METERS.
NOTE THAT AN ANTENNA SYSTEM WITH GAIN WILL GENERALLY HELP BOTH TRANSMIT AND
RECEIVE SIGNAL STRENGTH IF POINTED IN THE RIGHT DIRECTION.  THE TRANSMIT
AMPLIFIER WILL MAKE YOUR SIGNAL STRONGER AT THE FAR END, WHICH IS SOMETIMES
