hi dears
i'm newer here.
i have some questions about loran-c receiver.can you help me?
i want to know how can i find third zero crossing in loran-c receiver?
i find third zero cross by peterson 's method from this paper:
Analysis of Noise and Cycle Selection in a Loran Receiver
but due to

Hi
The concept you most commonly see is a curve fit approach. You know the
structure of the waveform through several cycles. You can fit this model
waveform to the observed data over a large number of points. As you fit more
points, the impact of the noise is reduced.

Given the number of people who have popped up as PDP-8 junkies, I suspect there

A couple of guys have expressed interest in this unit, so I think it is
spoken for.
Hopefully the adoptive home will post up about their experience with this
after they get it running.

Hi Paul:
It was your reports of the Great Lakes chain that got me interested in
this. I live in St. Paul, Minnesota, so I am hopeful of hearing it here. I
have a couple other LF receivers with which to try to hear Loran C, so I
still have options.
Obviously, before I invest much in this, I want

A couple of things. They are not the gov. They go home on the weekends.
So do take a listen to 100KC during the week.

it actually is.
Though the nixies are nice. I guess my loran simulator would drive it.
But can't

That is indeed interesting because the only rcvr I knew that needed a pdp 8
was the older actual station monitoring units.
I would strongly believe if you know what the 5000 wants these days its
very reasonable to emulate the control system.
