EMI-RFI and Noise related HF Radio Station performance loss HF radio performance loss due to EMI-RFI and noise in and around the station
environment is often a major issue that could almost cripple the
communication capability. This is especially true during conditions of low
SSN, the way it prevails during the ebbing part of the Solar Cycle. Many amateur radio operators do not realize the real consequences and the utter magnitude of loss in their radio stations performance. More often than not,
we have heard statements like The HF bands are now dead at low SSN, the
only viable way is to work HF using FT8, SSB radiotelephony is hardly
possible during low SSN conditions, I think I need to invest in a linear HF power amplifier, etc, etc We have heard all this far too often. However,
it is not necessarily the whole truth. We all agree that during low SSN conditions, negotiating the HF radio bands become more difficult and
stringent in comparison to what happens during the better part of the Solar Cycle. When the... Click Here to Read Full Article []
