Although I agree that by and large the stations with high good antennas stand the best chance for transmitting across the atlantic, small antennas do offer some advantages for reception. In particular, small antennas pick up far lower local QRN levels, which is particularly important on lf. It is worth noting that G3KEV apparantly does not hear my signals with the large antennas he uses - several far less well equiped stations at comparable distance copy me consistently. Of course for the transatlantic work low angle radiation is a must - a high vertical coupled with an excellent ground system does seem ideal for this. But that is not to preclude the better equipped stations with Marconis and similar, and there are several UK stations not on Mal's list who must have a sporting chance. As G3XDV says, the first thing to do is to establish if DCF39 can be copied in the USA - I suspect if it is not received there as strongly as we hear CFH the chances are slim. 73s Dave G3YMC dsergeant@iee.org http://ourworld.compuserve.com/homepages/sergeantd
