The big disadvantage is that the sensitivity of the grabber captures will much more often be compromised by sweeping carriers from neighbourhood SMPS sources. 73 and have a good time Markus, DF6NM --part1_2da.5507422.31585f58_boundary Content-Type: text/html; charset="US-ASCII" Content-Transfer-Encoding: quoted-printable Hi Wolfgang,
