HR-80• 4

INTRODUCTION:

Our HR-40 and HR-80 models are thought of as “best for beginners”

because Hams with a Novice or Technician license can operate CW in

the 40 and 80 meter bands. If you like plenty of action and DX (long

distance) communications, the 40 meter ham band is the place to be.

Almost 24 hours a day there’s something interesting happening on 80

meters.

These are several groups of people who will enjoy this Ramsey HR-80

Receiver:

• Experienced Ham operators who want a simple extra receiver for

keeping one ear on 80 meters while doing something else.

• Beginners who would like to start by listening in on one of Ham

radios most active bands.

• QRP builders who want a quick, easy and reliable NE602 board kit

for 80 meter projects.

• QRP builders not interested in our warranty or following our step-by-

step assembly and use directions, but who want to get their hands

on our most versatile receiver PC-board and parts kit for their own

projects.

The Ramsey HR-80 has something fun and easy for each of them.

Note To Beginners: Building the HR-80 is really no harder than any

other of our receivers in this series. Just follow the directions carefully.

All you need to know to successfully complete this receiver is contained

in this detailed manual. Enjoy your HR-80 receiver.

RAMSEY HR-SERIES AMATEUR RECEIVERS:

All Ramsey Direct Conversion receiver Kits share the same basic PC-

boards and most components which are not frequency critical. However,

there are enough differences among the band characteristics, desirable

operating features for each band, and differences among the people

who would most typically choose a particular band, that a separate

instruction manual is published for each receiver.

Other circuit details which vary from band to band include the tuning

range provided by the varactor circuit. “Bandspread” for favorite band

segments is easy on 160 or 80 meters but requires other considerations

on higher frequencies. Also, some bands appeal to QRP operators more

than others, and some are better suited for portable and travel use.
