[time-nuts] Austron 1250A FS
List, I am selling my Austron 1250A. The meter readings are all in the OK range and has a 5 MHz output which I've not calibrated. It's in good cosmetic condition. It comes with the factory manual,extender board, relay rack mounting brackets, spare fuses and a AN connector for attaching an external battery pack. The one problem it may have as I was told when I bought it is that the rear EFC might not work. (I never took the time to find out if it is a problem, I just powered it up. Has been in continuous operation for over 6 months.) Asking $250 plus shipping from 92220. If the buyer wishes, I can remove the Ni-Cad battery pack and dispose of it in an approved recycler and save some money on the shipping. If interested, please send me an ORIGINAL email so it won't get mixed in the TN nuts posts.

Re: [time-nuts] Austron 1250A Tuning tool
I adjusted my 1250A using a 1/8 brass rod that I got from the hardware store. I filed down the end to make it into a screwdriver. This worked fine. I could tell when the tip was engaged with the screw in the oscillator by feeling it fall into place and then I could make the adjustment. The brass didn't have any effect on the frequency. When I removed the tool the frequency didn't change. A metallic tool is needed since the adjustment screw needs some torque to make it turn. -Original Message- From: Ole Petter Ronningen Sent: Saturday, February 21, 2015 1:07 AM To: time-nuts@febo.com Subject: [time-nuts] Austron 1250A Tuning tool Hello My 1250A has drifted outside the range of the front panel control, so the coarse adjust needs some fiddling.

Re: [time-nuts] Austron 1250A Tuning tool
Fantastic, just what I needed. A little gentle persuasion with a knife coaxed one of my crappy screwdrivers blade to become long enough (or rather, the handle short enough..) to fit. 5 minute job once I knew what is on the other end.

Re: [time-nuts] Austron 1250A Tuning tool
I've had the ovens apart to replace a dead 3N128 in one of my 1250As. What you are adjusting is a trimmer cap in the oscillator circuit, and if too much pressure is applied trying to engage the slot in the trimmer, it is easy to bend the trimmer off at an angle where you will never be able to find the slot again. The Austron supplied tool is a dielectric rod of 18 cm length, 3 mm in diameter, with a 3 mm steel flat blade 2 mm in length protruding from the end of the rod. The blade easily fits into the trimmer's slot, but as was mentioned in the previous post, some of the trimmers are sticky, and require some torque to get them moving. I measured the inner oven's temperature as 63 C which is the temperature that trimmer lives at. -Doug W6DSR -Original Message- From: time-nuts [mailto:time-nuts-boun...@febo.com] On Behalf Of John Reed Sent: Saturday, February 21, 2015 5:56 AM To: Discussion of precise time and frequency measurement Subject: Re: [time-nuts] Austron 1250A Tuning tool I adjusted my 1250A using a 1/8 brass rod that I got from the hardware store.

Re: [time-nuts] Austron 1250A
Thanks all I decided to replace the batteries, expecting delivery any minute now. Surprisingly expensive to replace those NiCd's.. Anyway, after looking at the schematics a bit, I was able to stop the relay chatter by setting the unit to charge, and holding down the reset switch for a couple of minutes. That gave the batteries enough charge to power the base of the transistor that holds the relay.

Re: [time-nuts] Austron 1250A
Yes. I had the same issue with several of my 1250s. Unless you intend to use it through a power outage, just disconnect the batteries and all should be fine. It will also be a lot lighter if you take them out. Regards - Mike Mike B.

Re: [time-nuts] Austron 1250A
I own several of these units, and have for sale several more if anyone is interested. I can verify that a New Old Stock unit straight out of the box, needs to have the cover removed, and a piece of Styrofoam spacer removed from the relay you mention. It sounds like you have done that, or the seller did it. Then for many minutes with the 1250A on, and the battery switch in charge, the relay will buzz. This is perfectly normal, and is mentioned in the manual for the 1250A. By-the-way, the original battery in all the units I have powered up, never achieve the capacity to run the standard for more than a few minutes. They can be replaced with new cells, but I have also never seen any of my units with leaking cells.

Re: [time-nuts] Austron 1250A
Hi Ole Mmmm well I have 2 and a friend has one all had dead batteries, quickly removed, but we didnt have a manual then so we just ran them without them batts. Our power is quite reliable. My pair have been running continuously for around 7 years now with no signs of problem and no relay chatter. The crystals are well aged now :-)) Alan G3NYK - Original Message - From: Ole Petter Ronningen olep...@gmail.com To: time-nuts@febo.com Sent: Wednesday, February 18, 2015 5:46 PM Subject: [time-nuts] Austron 1250A Hello On a whim I purchased an Austron 1250A off of eBay, tested for power on only.

Re: [time-nuts] Austron 1250A
Ole I will guess that without the pack the bus voltage may go high and that they also used the pack as a filter cap. So you should be able to find a free manual on one of the sites. KO4BB is a good guess. It may be as simple to start as a 10,000 uf cap to get going. The oscillating relay may be 60 Hz. Best of luck those are nice units.
