[time-nuts] Re: Looking for Manual or Info for a ESE ES-180 Master clock

[Gregory Beat]

ESE has manufactured Clocks for almost 50 years (starting in Broadcast Industry).
The earlier products were hardware based, with their later products using embedded processors/firmware code.

IF you send ESE an e-mail with the Product Number (ES-180 in your case)
and the Serial Number, THEN they normally supply a PDF manual with Parts List and Schematic.  Firmware listings for embedded processors (later products) not provided.

The ESE ES-180 WWV Master Clock was discussed on “time-nuts” in 2014.
https://www.febo.com/pipermail/time-nuts/2014-May/085002.html

The ES-180 product decodes time code data from WWV HF broadcasts (5 bands):
2.5, 5, 10, 15, 20 MHz.

Master Clocks using WWV have largely disappeared (commercially) with the wide availability of GPS receivers and the addition Phase modulated Time Code in 2012.

Over the decades, ESE has refreshed products with Technology advancement (OCXO, GPS, Internet/NTP, and service or parts obsolescence).

I deal with ESE professionally (“El Segundo Enterprises") and 
IF the documents are for discontinued products, they try to be helpful.

I have previously posted ESE support information on time-nuts,
for the restoration/repair of ESE Master and E911 Clocks.
Good Luck.

HI Guys,

Cross posting this message from the NTMS reflector. 
Figured time-nuts would be a good forum for this question.
If you have any information on this unit, 
Please respond to Mike K9MK at k9mk at flash.net
Thanks,

I picked up an ESE Model ES-180 Master Time Clock.  
It appears to be syncing to WWV or maybe WWVH, I can't tell for sure.  
The ESE model 185 appears to use GPS, I don't think this one does.

Might anyone have a manual or spec sheet or something that might shed some
clues as to operation, antenna requirements, and what the speaker might be
for (I know sound, but..).

It is a 1RU 18" rack mounted with an on off switch, 6 digit time display,
and a speaker with a volume pot.
Any info would be appreciated.

Thanks
