Re: [time-nuts] Cathodeon TCXOs??
Hi Paul thanks for looking, the pin out for these beasties is the real info I am after. It is amazing how rapidly all the data has been lost..I am glad I saved some from the WPB myself.

Re: [time-nuts] Cathodeon TCXOs??
I'm pretty sure that I have a Cathodeon filter/osc catalogue at home (work reference material relocated due to constant 'downsizing' of storage space by my employer - "everything is on the internet"); I'll check up on it tonight. Paul G8GJA -Original Message- From: Alan Melia [mailto:alan.me...@btinternet.com] Sent: 24 May 2009 20:12 To: time-nuts@febo.com Subject: [time-nuts] Cathodeon TCXOs?? Hi I wonder if anyone still has a datasheet/catalogue of Cathodeon products. This firm made crystals and oscillators and filters in the 1980 and 90s in Cambridge, England. (It is only 50 miles up the raod but I have not been able to find anyone who still has any knowledge of the products.) The units are FS5980/01 10MHz FS5951/315MHz I think the the 10MHz may be a TCXO,VCTCXO or even an OCXO, but the 5MHz does not have enough pins to be other than a TCXO. The spec would be useful (I think I have that from a previous query) but a pin-out is the vital information because none of the pins is common to the case, so it is difficult to work out the connections with an ohm-meter.

Re: [time-nuts] Cathodeon TCXOs??
Part of Cathodeon still exist in Cambridge. Not crystals unfortunatly, but the lamp and discharge tube business. They are now part of Heraeus. www.cathodeon.com still links you to the website. It might still be worth an email, there might be some old hands left. I know of one case were an enquiry for data led to an invitation to "come and clear out our old store room"!

Re: [time-nuts] Cathodeon TCXOs??
Thanks Roy, yes I know several peple who worlled for Pye / Philips, and the firm I was involved in was a dealer for a while in the 80s. I have some data but not on those units. I cant remember when Philips bought them but it was a "kiss of death" !

Re: [time-nuts] Cathodeon TCXOs??
Alan The Cathodeon Company was part of Pye of Cambridge, which in turn became part of Philips. I understand that nothing has survived of the old Pye Group, so it may be difficult to obtain any new data.
