Yes M0BMU and G3WCD manage to decode me regularly now, but further than Jim I struggle on 137.5kHz, although G3YXM did decode me a few weeks ago at 148km. The much lower ERP because of the lower radiation resistance on 137.5kHz is really noticeable in (lack of) results. An increase in loop wire diameter is needed, so I need to buy some thicker wire and get it up. I also should be running more power, but was rather hoping to keep to 5W from the PA to see what is possible with QRP. On 500kHz with the same antenna and RF power from the PA it is a different story with decent DX reports now being regular. Perhaps I should go back to the vertical Marconi arrangement and try to get this sorted with a decent loading coil, top hat, etc. as the loop is directional and will be in a null for some stations. 73s Roger G3XBM On 23 October 2010 01:06, Dave G3WCB. wrote: > Hi Roger. > > No decodes here tonight, although I thought I saw traces of your signal on > ARGO earlier on.
