Is this typical? or better still can anyone suggest what it might be please? DCF39 is clear on the trace and very strong.. Even better, can I get rid of it. The next step is probably a noise canceller but I'm not sure how effective this will be on a broadband noise pulse Ant is a dual vertical wire to approx 10m high with a pair of 18m horizontal Capacity wires seperated by abt 800mm in an offset 'T' formation. Looding coil is about 5mH. Rx pre-amplifier is the Mk1 G0MRF kit feeding my FT-920 HF rig. Thanks Martyn
