Halcyon OFS
I have been given a Halcyon Electronics OFS1 standard which seems to work,
it's a version that has 198KHz and 162KHz selector on the fron and after a
reasonable period of time it displays 'lock' and gives a nicely stable 1,10
and 10 MHz output on the front panel BNCs, (I know, it should be 1,5 and
10MHz out, read on)
Does anyone know of a PDF manual? This version has two KHz crystals inside
it and I'd like to see how/if it's been modified so a manual with a
schematic would be even more useful.

No trees were harmed in the sending of this mail. However, a large number
of electrons were greatly inconvenienced.
I have a little Halcyon information I managed to find a few years ago
when I acquired a couple of PFS units. It includes a brief document on
OFS alignment.
I'll mail the documentation to you directly...

Hi Clint I have had one of these from new. It divides the amplified
incomming carrier by either 99 or 81 (4526) and phase compares with 2kHz
from the divided down 10MHz discrete VCXO to phase lock the 10MHz. My unit
serial number 1151 has no other crystals in it. It possible they are filters
for the BC carrier frequencies.
Halcyon ceased trading about 10 years ago, I think the PFS that Stephen has
includes a sythersiser locked to the 10MHz. I never received a manual as
such merely an A4 sheet printed on one side. I have never even found a
circuit diagram, despite contacts who knew people that worked there.

Thank you Stephen, Nigel, I'll take some pictures of the board in my OFS-1
but it doesn't match any of the pictures I've tracked down so far.
Interesting that the board mounted on the rear of the enclosure with the
trimmers appears to be Vero or perf board of some description...

Hello to the group. I suspect I will never see such a unit in the states.
Also it wouldn't be useful.
But that said its sounds as though its a traditional simple receiver that
should be able to be reverse engineered. At least for the signal and
locking chain. If a micro is involved then things get fuzzy fast. Anyhow
good luck with you digging in.

Mine is somewhat different to that model, the case is the same as the
leftmost one but the board is quite different to the middle picture.
I'll post some links to pictures of the internals and start drawing out the
circuit over the coming few days.

I got a Halcyon OFS-1 a while back, and found it was virtually
impossible to use here in Denmark, which seems to be located too far
away from the Allouis (162 kHz) or Droitwich (198 kHz) transmitter
sites. One major design flaw of the OFS-1 is the digital divider used to
divide an analog signal.
You can find more information about an experimental modification to
increase the robustness and usefulness of the OFS-1 here:

I may be able to give you some insight. I live some 1500 + miles from WWVB
in the US on the east coast. Not a favored transmission direction.
So for years I did the small loop and loop stick game.
Then 5 years ago I built a real shielded loop. 10' X 10' 800 ft of wire
approx. Then a preamp. Its sits 140 ft away from anything in the woods
about 10 ft off the ground.
The difference it has made in my ability to consistently use wwvb is
amazing. Daytime was 20-30uv maybe now 300uv and at night 1000uv and more.
The loop was cheap to build. Get 25 conductor surplus shielded cable. It
doesn't have to be 25 wires especially since you are at 200 KHz.
See if that doesn't help you in Denmark.

Paul

It seems I have a hybrid, on the front panel it's an OFS-1, on the serial
