The BP20 is a high quality
■ professional audio filter with an
amatuer price tag. Operation is a
I piece of cake so why not cut the QRM
f and get yourself a piece of the action!
No other state-of-the-art filter comes
close to the outstanding
performance of the BP20. Twenty
orders of filtering gives an incredible
80dB of stopband attenuation that
really cleans up the signal while the CA- >jj\
extremely flat passband & freedom Methyi?'
Spirt
ringing is a sheer delight for CW & ^0
RTTY. Unlike others, a night school
course is not required to operate the BP20.
. Just select the mode & trim the bandwidth. Whats
. more, it connects in seconds to any equipment with
/ the lead provided. Hearing though is believing as we
. found when using with a professional receiver costing
' several thousands of pounds. The results were fantastic
so think what the BP20 could do for you. The BP20 uses
very little current & will work on any dc supply from 12to
26 volts. Only one other product can give as much
enjoyment & that of course is our Microreader, a self 80
contained CW/RTTY decode & display system forthe HP
bands. To order or for more information contact

Once Bought - Never Replaced unwanted noise via 180° phase shift between the
magnetic and electrical wave, exactly what is required
from 1 to 14MHz where the electrical noise is virtually
unbearable.

the frequency designated for that model the Control
Box enables the user to operate the antenna from the
lowest to the highest part of the frequency with no Transcelvlng
gaps. Loop
