Hartmut and Markus chose the freq.  At that time it appeared as good as cou=
ld be found. If a better one is available to everyone I can move to it with=
out a problem [licensed for 68-76 kHz].  It should be such a freq that allo=
ws a couple other spots no more than a Hz apart for Dex and John Andrews an=
d maybe Jay and Warren who may be coming on.
Artifacts from various services has been a problem.
