I would consider that figure acceptable. With my K3 the isolation between ANT1 and ANT2 is 42dB worst case, 56dB Max.
Moving the single wires around made no difference. I suspect that the level of isolation is determined by the ATU PCB layout. Given the size of that board I think that the isolation obtained is reasonable. 73 Stewart G3RXQ On Sat, 3 Jan 2009 13:43:21 +0100, Koppendorfer Klaus wrote: > yes isolation between ant1 and ant2 is very bad... > if I have time I try to change the silgle wires from the rs323 ports to the atu-board to koax wires, maybe this will help a little > > 73 > OE6KYG > KX1 244 > K2 1331 > K3 115 >> -----Ursprüngliche Nachricht----- >> Von: elecraft-boun...@mailman.qth.net [mailto:elecraft- >> boun...@mailman.qth.net] Im Auftrag von Dick Roth, KA1OZ >> Gesendet: Samstag, 03.
