When I designed mine maybe 20 years ago, I did consider using something
like phone cable and ribbon cable, but there was a good performance reason
for using the heavier wire. Sadly I can't recall why right now.
FWIW,

The BFO is (are, one for USB and one for LSBY the only oscillator that is not
phase locked to the HP10811 inside, and that can be remedied, so it is not
hopeless.

I have used 25 pair telco cable.
The issue that can happen is the inter pair and strand capacitance can
exceed the resonance frequency of the loop. Or resonates below 60 KC. Just a
heads up.
Using a 3 foot loop was not a problem.

This was my concern how would it be remedied. Simply is the better ?
I would understand DDS as an example

Understood. I have gotten better with the loops over the years.
Someone mentioned 1000 strand phone cable.

Just listening to 100 KC and its just noise at -121 dbv.
So they did shut Canada down in August.
Will listen tonight to see if Europe can be heard from the east coast.

Gents,
Thanks for all the input on the HP 3586B and the Austron Loran C receiver.
I’ll try to distill what’s been said.
It appears that using the HP 3586B for a WWVB receiver isn’t a good idea unless
I would use my HP 3336B or some other method to phase lock the BFO. Since this
seems to
Its not just diurnal shift it plain old jumps anytime.
Have been monitoring for periods from the eastcoast using both a Tracor 577
and 2 X HP vlf117 rcvrs. All kinds of stuff occur.
But then the older gents know all about that reality.
Some may speak up.
I like you want a second source but will
That would explain why my 2100T hasn't worked since I got back
from vacation.
When the US chains shut down, the commerce department said it would
continue those stations that serviced Canada (because of treaties),
until November 2010. I guess Canada decided it didn't need that long.
I tried
Don't think any of it mattered.
The goal was to save the operating costs to show that we are thrifty bunch
in government.
I was caught a bit off guard I did check my references/standards in late
July even early august. Had looked for notices and missed them.
Would have taken final checks.
Oh well.
Whether they realize or not isn't the issue. They simply don't give a
crap. They don't have to. They are the government.

There was a post a couple of days after the shutdown that they had blown

Yes that was in alaska it was on the news. 1200ft down in a few seconds.
They blew it up because it has a very grave structural issue.
I suspect given a drop of time that will be the fate of all the towers.
Hmmm now whats happening with those nasty HP Cesiums??

NOW THAT IS AN INTERESTING THOUGHT!
What the government has done by this order consists of a taking
of property. We should be able to file for compensation for the
loss of use of all of our expensive timing equipment.
They got around that issue with televisions by giving rebates on

All of this design and mod info is wonderful and great to fill an
engineering project workbook. You can spend about $500US and get a complete
HP
working system including GPS antenna which I have been monitiring to 10-12 for
14 mos now and it is stable
Yes indeed. I also have a hp rcvr. But Pauls request was for an alternate
approach.
I regularly matched LORAN C wwvb and GPS. It was nice having an alternate.
wwvb really isn't but its about all we have now.

has to be a way) and we have a non-Govt. time standard if needed. A

Uhmmm There is this station called WWV that does just that on
at least 5, 10 and 15MHz.
And if you are worried about it being broadcast by the US government,
you can always try CHU in Canada.
And if you are worried about the station being in North America,
there are time stations in
a) broadcasts aren't legal for US hams
b) ionospheric uncertainty in the skywave path makes this no better than
WWV
c) Whats wrong with GPS and/or WWV and/or CHU or whatever?
d) A cheap Rb would give you a local reference that is much better than
what you could do with receiving something
Wow you really missed my point and by having someone
listening/monitoring it is not broadcasting. Especially if it is in reality
for the most part... telemetry.
Maybe I wasn't clear or maybe my message could have been misunderstood. For
that, I am truly sorry. I was thinking along the
One more note before I just read the posts for a while...

Do some reading on telemetry and when broadcasts ARE allowed. I've been a
