Hi Perrier
 
It's a WWVB receiver, not Loran, with a built in phase comparator,  hence 
the strip chart, that can be used to compare its own oscillator or a  local 
input with WWVB, and is another unit affected by the WWVB changes.
 
Those switches on the front panel select an output frequency  provided by 
internal dividers.

However, the 8164 does have some limitations as highlighted in John  
Ackerman's very interesting observations here.....

List,  There are several Spectracom 8164 receiver available on  Ebay.

My question: on the front panel bank of frequency selection  switches, the 
left hand switch is marked .1MHz.  Is that really a 100 KHz  (for LORAN) 
setting or is it really tuned to WWVB?

If it truly is tuned  to 100KHz can it be hacked to 60KHz in a reasonably 
practical  manor?

Regards,

Perrier
