[time-nuts] Odetics 325 - 865

[Robert Atkinson]

Hi Roy,
  Welcome to the group.
  I've a couple of the sat-sync 325 receivers. Rob has covered the basics of the antenna question, the best way to determine if you need a down converter antenna is to put a 'scope on the antenna connector and see if there is a sine wave 10MHz signal as well as the 12VDC. An "R" suffix to the part number indicates a retrofitted L1 (standard 12V antenna) GPS RX. Some also have a label stating a 3rd party retrofit GPS has been fitted. The original downconverter GPS is a Magellen OEM in a big (about 8" square by 3" high) box in the bottom of the unit.
  At least you don't have the common problem with these units, a failed switch-mode power supply. 
  Where in the UK are you located? I'm in Dorset on the south coast.

  Gentlemen

Pleased to join you - I major in "high-end" test equipment, and have recently added a couple of Watkins-Johnson Rx's -- Dual 8607 (20 - 2032 MHZ) ,and a WJ 8700 again dual LF/HF (to 32 MHZ). But I have now gathered a couple of items of "Time & Frequency" . The first one is a Radio Code Clock RCC 8000, this receives the 60 Khz Standard frequency transmissions from our UK transmitter. This is fine - works OK. Now I have a bigger challenge - I found a ODETICS Model 325-865 SatSync which has been gathering dust since 1998 (last date it was active). 
It was switched on (and no antenna was connected), I don't have one. It came to life and scrolling its menu it shows a date in 1998 and a set of co-ordinates which suggests it was probably a ship installation. I found my way to your site through searching for info on this item, and I gather that some of you have this item of equipment - can you help - I gather that it requires an active antenna - what can be found or built to meet this need?
Also the system is "Locked" - what do I do to clear this problem ( the menu display suggests I refer to the manual !!) Is it possible to obtain a manual or copy of such. I must admit that it is a very well made item and must be worthwhile to re-establish. looking forward to any help you may offer.

Roy
