I have been reading with interest John Miles' page about his Tbolt 'upgrade'.
http://www.thegleam.com/ke5fx/tbolt.htm I have a newly acquired Tbolt here, and also have lying around an almost identical 10811-60111 OCXO which I am considering using with it, exactly as John describes. However my Tbolt is of a later vintage than John's (2005 date code) and I wonder if that would show as big an improvement as John reports. The on board OCXO on this one has a Trimble sticker on it, but otherwise looks similar to the one pictured on John's page. The GPS receiver area of my board also looks very different, but I don't think this would have any effect. Not having the sort of phase noise measuring facilities here to be able to test it, I am wondering if anyone else has done this with a similar vintage Tbolt, and could say if it is likely to show as big an improvement as John seems to be getting. I was a little surprised at the amount of short term variation, of the order of minutes duration, that I was seeing on another Tbolt when using it to set a Rb standard. The obvious answer to my question is to try it and see, but I'd appreciate hearing from anyone who has tried it!
