Hi Marc, The rx is an ex-Royal Navy type CFD - 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 electron
Whoops! Type CJD, sorry..... Manufactured by Murphy, I think, but I could not find a manufacturers nameplate on mine. 73's Paul G8GJA Hello all, I m looking for information about this VLF receiver. P
Marc, For most amateur VLF work, 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 extremely narrow bandwidths. St
