The receiver in use for that grabber is a drifty old IC735 which is about
20Hz off cal, those 3 strong lines should be a little HF of where my
graticule indicates! I'll tweak it now.
If the noise is off I can see Loran lines every 6Hz or so. God knows what
it'll be like when Rugby comes on!
Very interested on the blanker discussion. Sounds a bit like the
"woodpecker" blanker that my TS850 has, it's absolutely useless for normal
noises...

I noticed that G3YXM was running screen grabs on 137.700 kHz this morning,
with an Argo 3 second slow screen. I took a shot of the same spectrum here,
and placed them side by side:

Mains-related interference aside, you can see the effect of a target-rich
Loran environment. I have Loran sites at 194, 412 and 587 km, with three
chains represented.
