Can be this considered logic? 73 de José, EA1PX ----- Original Message ----- From: "Alan Melia" To: Sent: Monday, January 19, 2004 4:32 PM Subject: LF: Re: RU6LA acty > > ----- Original Message ----- > From: "Ed Lesnichy" > To: > Sent: 19 January 2004 11:45 > Subject: LF: RU6LA acty > > > > Dear LF-enthusiasts! > > Some conclusions from last acty: the propagation was very unstable on > > a distance up to 3000km at the night but for me there was by a surprise > > a very good and stable propagation to daytime (Jan 18) > > Hi Ed, I guess I was a bit too optimistic.
