Locator here is FN15nt.  Thanks for the offer of help in setting up a grab=
ber.  I'll have to get some kind of receiver working=20
reasonably well first.  I have in the past copied SAQ (very weakly) using=
 a 40-turn square loop (28" sides) with an OP-27 preamp
running into a sound card using SM6KLM's software, but I'd need something=
 bigger than that for your 9 Khz signal.  Let me see=20
what I can come up with.
