Carl, before I send you on a wild goose chase, I am in error. The sweep
works on 6M. However, I wasn't seeing the usual ragged noise baseline
that I observe on HF. The sensitivity may also be worse on 6M, because
I thought I had heard several weak sigs that weren't displayed by the
sweep. I will double check today. This morning I was observing some
strong local sigs without problems.
Sorry about the bad info.
73, Joe
