RTL-SDR is the worst device to get started on ham radio. people gloat about= it, but this device was never intended for HF radio but for TV, so range s= tarts at about 50MHz and goes to 1GHz. Sensitivity is horrible because the A/D converter is only 8-10 bits, so the= full range is less than 60dB, so you will receive only strong local statio= n (FM) or similar. It is good to experiment, but I would not recommend for beginner on SDR. A single band Softrock and a PC with stereo sound card input is way better = to get a feel about SDR. for low cost entry do the SDR World, nothing can beat the products of Tony = Park at Fivedash.
