Hi to all,
          if you see the sixt image of the advertise you see a FRR-21 (VLF 
receiver) with a smooth (gray?) case, is it possible that SRR (shipboard 
table top) and FRR (fixed rackmount) were similar and MRR (mobile service) 
should have a corrugated case? I don't have the T.M. on hand so can't check. 
What is the knowledge of the list? I haven't this kind of receiver so I 
should like to know more about it. Many thanks to all. Federico IZ1FID
