However, great to hear from David G4ASR who has been getting on really well with his. He hooked the SDR up during yesterday's excellent Es opening on 70MHz and was hearing a number of stations including an Estonian on FM. It's working well on 144MHz too and Dave was getting good results from the GB3VHF beacon. Sean, G4UCJ was also doing well with his and receiving stations on 70MHz - including the wideband FM which was very strong yesterday. Dave reckoned that his dongle was about 7KHz off 'calibration' on 70MHz. I found mine was about 20KHz off at 145MHz. You can cope with this using the 'shift' feature in SDRSharp.
Given that it's only £11, I've ordered another dongle and hopefully that will behave better if I don't transmit close by!
