For local reception, receivers with RTL2832U chips are a cheap option. They are also called RTL-SDR. I have simply been using a long wire as a "random wire antenna". Some of the older dongles also need an upconverter to be able to tune into low HF frequencies:

An upconverter for the RTL-SDR translates low HF frequencies ‘up’ into ones that are receivable by the RTL-SDR. This is a different method to the direct sampling mode used in the V3 dongles to achieve HF reception.
