[Elecraft] Noise Blanker K2

Thu Oct 2 08:58:59 2003

Wolf - mni tnx for posting ur mp3 - I'd be absolutely astounded if mine
worked that well !!!!!  Once in a great while it will make a difference (NOT
on light dimmers or any powerline noise - I even changed one of the
time-constant caps as noted in previous discussions of the blanker - tried a
lot of different values - all to no avail! ) on the ignition noise from a
passing car but for the most part just doesn't touch anything that I need it
to.  I do have the DSP and it is at least useful - a bit too aggressive -
but useful.  Tnx agn for ur post.  73 es gud dx  --don n4hh K2/100 #2028
