Didier, Several years ago I obtained a number of those modules intending to build a GPS steered standard.
At the URL below you will find a large (24MB) ZIP file that contains much of the data that I put together regarding these R-1051 frequency standards. Some of the files included are my original work and some are from other sources. I never completed adding a varactor and steering one of these modules because I got involved with the then easily available Z-3801A units. http://www.on-sitetraining.com/wa8drz/ Feel free to ask further questions - I may or may not recall all the details.

I would appreciate it if anyone had the schematic. The explanations on eBay would probably be sufficient to do the job, but I would prefer to be sure of what I am doing rather than guess (tall order...) Thanks in advance.
