Mike,
During a major DX-pedition in the night or during a contest on 160
meters power company line crews are not probably going to respond. Most
times it take days or weeks for them to respond. My power pole banging
ended over 50 years ago as now so now I try to plan ahead as well as see
what the rain forecast is like a down pour a few days before to wash the
salt from the HVAC pole insulators. In such noise cases this may be the
only hope, except that some power companies to reduce line loses have a
solution they apply to the insulator(s) usually in a planned maintenance
schedule to a problematic area.
During power outages on the island listening to the absence of
cumulative noise sources is a real treat. However here these outages
are mostly caused by storms and the associated tropical QRN is far worse
then some periodic noise which many DSP's and NB's can significant
reduce. Also the last 20 years has found serious TB Dxers having some
sort of directional listening advantage over a noise source located some
distance away by using Beverages, Flags, Pennants, Array Solutions,.
K9AY systems, and loops.
By point here is that pole banging with a sledge hammer is no longer
needed and today quickly falls to the bottom of the list of solutions if
at all.
Best wishes to all for Merry Christmas and a New year filled with TB DX.
