* In urban areas, it's sometimes necessary to add some front end filtering to eliminate reception (or at least reduce it) of MW signals. These signals can cause multiple false signals (often heard as distorted spurs) to appear throughout parts, or all, of the HF spectrum. | * In urban areas, it's sometimes necessary to add some front end filtering to eliminate reception (or at least reduce it) of MW signals.

HF Capable Receivers
- Articles on various general coverage receivers produced in the past can be found here
- These Widebanded Receivers can receive HF - however, the computer driven Icoms are notorious for poor adjacent channel rejection, selectivity and overload issues.
- Our Other HF Receivers article has links rescued from RadioIntel's old site.
- Here are the mailing lists for many older radios.
- The emerging field of Software Defined Radios adds another class of equipment usable on HF
- The Receiver Reviews category has numerous links on receiver reviews, many of which are online
- Many newer HF Amateur transceivers also include a general coverage receiver as well. In most cases these receivers perform very well

Antennas and Filters
- No matter how good the radio, without an antenna, it won't hear very much. Here are 2 places with lots of links and information on the subject
- HF Antennas
- Loops Some are broadbanded enough to reach the HF spectrum
- See Bobs America website for more technical discussions on preconditioners, tuners, reviews and more
- In urban areas, it's sometimes necessary to add some front end filtering to eliminate reception (or at least reduce it) of MW signals. These signals can cause multiple false signals (often heard as distorted spurs) to appear throughout parts, or all, of the HF spectrum.
