I have got an ICOM R75 HF receiver and wonder if I could use that?? One thing I dont understand is what are you supposed to hear?? Just hissing noises or what? Half wave dipole looks easy enough, and putting it East - West no probs. Set receiver to 30MHz and listen to the Sun?? More really simple info would be great. I've also got a Uniden scanner which goes into the hundreds of MHz. Any good??
