I hope that's propagation and not my transmitter! EbSynth is good but I'm not convinced yet that the multiplier is behaving. We've still got that discrepancy with the carrier strength and BER. Perhaps that's just a consequence of the erratic phase. That's something I've never properly tested for and characterised. I've been glancing at my signal on Gary's page at http://myweb.tiscali.co.uk/wgtaylor/grabber2.html Not being used to transmitting, it's quite a novelty to see my signal on someone's spectrogram. This is good fun. J.B. wrote > go to a motor rewinding shop and get some of the sleeving > they use to cover the connections of the windings to the > fly-leads. I know the stuff you mean, and it sounds ideal. Good idea, and I may know a place I can get some. It seems that getting the output transformer right is the hardest thing to do. Andy I'll have a look at those cores - I didn't know if they'd be any use at MF. I've got a pile of dead PC power supplies to strip down or maybe I'll get one from RS. I'm baffled by all the different core materials, I can never figure out what's suitable for what and there are so many. TX still on, valid EbNaut messages since 18:00, will probably run for another hour. -- Paul Nicholson --
