Martyn, any idea what distance to the grouse?
Yes mate, the Grouse was around 20ft, it was an overcast day with heavy
rain in the morning but he was pinpointed with my headphones, I couldn't
really hear it with the naked ear!! Its what you said later Walt, the
proof is in the pudding!!! You can have all the bench tests in the
world, but the actual recording is what counts in the end and the
quality. This recording was unfiltered too.
I haven't forgot Walt what you also requested with the Marantz recorder,
I do have some closer and much quieter recordings for you, but I have
been working around the clock and the Aussie is whipping me along too
:-(
