Glenn good afternoon.
Unfamiliar with that receiver. If its a location receiver for a plane or
boat then it has no value as they depended on 3 sites to generate a
location. Today the eLORAN tests have been pretty much single site that
fakes a secondary transmitter.
Things like Austrons and SRS can leverage the single site for very accurate
frequency.
But those receivers were intended for frequency or timing.
I am staying clear of the timing aspect because I am honestly not sure
the old method is actually being transmitted.

Eloran provides an additional bit in the pulses that actually does contain
timing and correction information. Though all of the existing receivers to
my knowledge do not produce this data as an output.

If the US were to invest in eLORAN then I honestly believe the 9th bit
could be recovered from the SRS and Austrons. Decoded and used for time and
propagation corrections. I have seen the actual eLORAN receivers and they
seem to be SDR like.
But nothing a cheap time-nut could get your hands on.
