My introduction to HF radios were on a KC-135A which had a wire antenna and a radio head with a limited number of crystals used for a limited number of possible frequencies. From there I graduated to a Boeing 707 (EC-135J) with five HF antennas: two wire antennas stretching from two...

There are quite a few receivers online that you can listen to HF communications. Some of them even allow you to control the radio for limited times. Some others are set to a specific frequency on the HF band that usually has a lot of activity. See theLive Tunable Receiversarticle...
Knowledge of the specific radio equipment being used, propagation, antennas, and so forth is still essential to use ALE effectively. b. ALE will not improve propagation. If poor propagating frequencies are used, ALE will not make them work better. ALE only works as well as the frequencies ...

The HF+ was touted to be as good as or if not better than high priced SDRs such as Perseus and RFSpace so until there’s a comparison against these on HF frequencies I may just hold off buying one, there’s not much difference I can see from the review between the HF+ and t...
