Re: [time-nuts] Halcyon OFS
Hi So let’s see, 140 feet that way would be three yards over … that way crosses the street and makes it to the back of his yard …. this way is past the back of the lot and four lots down …. that other way is over the other street and into his front yard ….

Re: [time-nuts] Halcyon OFS
Ole 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.

Re: [time-nuts] Halcyon OFS
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: http://dabbledoo.weebly.com/halcyon-ofs-1.html Best regards Ole Den 19-06-2017 kl. 17:15 skrev Clint Jay: 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.

Re: [time-nuts] Halcyon OFS
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.

Re: [time-nuts] Halcyon OFS
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...

[time-nuts] Halcyon OFS
Hi Clint, There seems to have been very little information available from Halcyon on either the OFS or PFS off air references. All I've seen is the OFS alignment document that Stephen is already sending to you. There were two versions of the OFS1, the later version had similar proportions to a Quartzlock 2A whilst the earlier was in a taller case and not so wide. That board in the alignment notes seems to match reasonably closely to a couple of photos I have of the earlier circuit board. I'll send you copies of those photos for reference as they might help you pinpoint any changes if they match your unit, but I've got no information on the later board so not sure how similar that might be. The off air section of the PFS1 was significantly different to the earlier OFS1 at least. Nigel, GM8PZR 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 areasonable 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 insideit and I'd like to see how/if it's been modified so a manual with a schematic would be even more useful.

Re: [time-nuts] Halcyon OFS
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.

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.

Re: [time-nuts] Halcyon OFS-1 Circuit Diagram or Manual?
Hi Mike I have had a Halcyon OFS-1 for 20 years and been looking for a manual/circuit during that time. Mine was bought from Halcyon and came with an A4 sheet of paper !Not alignment instructions!! I have been looking for detail ever since. I would certainly be interested to see a copy of the alignment instructions. I very nearly ripped mine apart several years ago when I found the output phase "breathing" with a period of about 100 seconds. After double checking my local standards and using another receiver, I contacted Peter Whibberly at NPL and they had not seen it because they integrate over a much longer period to get parts in 10^12. I was put in touch with an engineer at Droitwich, he looked but didnt find anything wrong (they did not have an off-air standard!) However the problem improved at the time of the inpection -)) Subsequently I got an email from Peter about 6 weeks later saying that the synthersizer had failed completely !! After the repair the phase drift against my local standard was much better and probably at the limit of short term daytime off-air measurementI couple of parts in 10^11 My case is a cream textured finish in two identical parts. The rear panel has a ferrite antenna hinged to it, though an expernal antenna can be used. I believe some of the later units locked an ovened oscillator and contained a dil-switch set synthersizer to generate quasi-synch carrier frequencies. It may be you have an OFS pcb out of one of these that has been recased?? Best Wishes Alan G3NYK - Original Message - From: "Mike Niven" To: Sent: Thursday, August 22, 2013 4:16 PM Subject: [time-nuts] Halcyon OFS-1 Circuit Diagram or Manual? I have acquired an old working 198kHz/162kHz off-air frequency standard that appears to be a Halcyon OFS1 circuit board mounted in a DIY case. I think this since it came with a sheet of alignment instructions from Halcyon which certainly ties up with the PCB layout but the case is not made to professional standards. So, nice enough looking, but with no manufacturer's logo or model number to really identify it. If it is an OFS1, would anybody have a circuit diagram or manual to enable me to confirm my theory?
