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.
- Also see our Winradio article. Winradios are generally considered to be much better performers on HF than their Icom cousins
- 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's a few places to get some links and information on the subject
- HF Antennas
- Active Antennas KB6RWX
- Loops Some are broadbanded enough to reach the HF spectrum
- The McGyver(tm) special
- 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.
