Marc,

For most amateur VLF wor= k, you will do better with Spectrum Laboratory in "locked" mode i= .e. locked to a VLF MSK signal. Then you can look for DAYS if need be in ex= tremely narrow bandwidths. Standard commercial RX are not good enough for m= ost amateur uses.

Hi Marc,

The rx is an ex-Royal Navy type CFD=A0 - I think! Used in submarines about = 2 generations before the current fit. I have the complete technical manual = for it but only in paper form, not electronic - used to have one of the rec= eivers too but just a bit too large - and doesn't quite fit in a standa= rd 19 inch rack :-(
If you want to borrow the documentation you are welcome - I could scan it b= ut this will take some time (large manual!).
