ive become interested in hunting down numbers stations that play over the shortwave frequencies. ive managed to capture a few, like the backwards music station, and a spanish lady speaking numbers through internet controlled radios. what id like to do is by a cheap receiver (anywhere from 20-50 dollars) that will be able to pick up the necessary bands and modes. i know that numbers stations are on the fringes of the bands and im not sure what kind of radio to get because of this. one i have looked at is the grundig G8 traveller 2. any suggestions and help would be appreciated.
