Some time back, somebody asked about how the K3's NB
handles the Hainan woodpecker. I don't think I saw any
response, though may have missed it.
Hainan is QRV 24/7 whenever there is something they want
to watch going on, such as the recent VK/W war games in
VK4. Several pulse rates are used & either some of rates
and/or combination of propagation results in pulses that
none of the NBs in rigs here can put much of a dent in;
other times they can take a healthy bite out of it.
The rest of the time, it pops up intermittently & has pretty
much rendered 40m useless when I turn the radio on
nowadays (as well as 80 & sometimes 30 & even 20m).
With the British & now Chinese woodpeckers seemingly
here to stay with us, I wonder if it might be possible to do
some 'predictive' blanking with the hardware NB gate (does
anyone remember the AEA WB-1)?
On a good day, these things are only 20 over - but usually
stronger & 'detected' blanking with 100-or-more kc of
S-meter pegging OTHR is a bit of a challenge...
