A Reason to retain SD duplicates of HD broadcast channels
A number of members have voiced opinions that SD duplicates of HD channels should be removed as being a waste of scarce spectrum on the transponders.
I beg to differ in this regard, specifically with regards to broadcast channels.
Inclement weather, fog, rain or falling snow can severely disrupt signal reception.
In many such cases the HD signals are much more susceptible to disruption and we can often lose HD yet be able to switch to the SD equivalent and get reasonably good reception.
Fog, the denser the worse, is particularly bad in that it seems to soak up microwave signals and often last much longer than rain or snow.
With weather seeming to be becoming increasingly problematic in Canada it seems that now is certainly not the time to put all our eggs in one basket, especially one as porous as HD.
SD signals are infinitely better than nothing!
