Re: [time-nuts] time-nuts Digest, Vol 109, Issue 57

Hi Chris, The fundamental issue was that the same code that worked elsewhere could not decode the 0x8F-AB packet data 100% of the time. I saw the length of this packet vary by a few bits at the code level, so I used a logic analyzer with serial decode to examine the raw data coming in to the

[time-nuts] RFTGm-II-Rb - can you gps discipline it without the XO module?

Hi Everyone, I've only got the RFTGm-II-Rb module. I found an interface cable specification here: http://www.ko4bb.com/Manuals/05%29_GPS_Timing/RFTG-m/RFTGm%20Interface%20Cab le.pdf Does anyone know if feeding a 1pps signal to pin 9 might discipline it? Or does it need the other

Re: [time-nuts] ThunderBolt Display

Yes, but not for technical reasons. I'm opting to build my own for the $15 in parts. Not quite free, but at the same time this isn't new to me and it won't take long and I'll probably learn a little. -Bob On Thu, Aug 15, 2013 at 11:22 AM, Eric Garner garn...@gmail.com wrote: Is anyone else

[time-nuts] Lady Heather without a PC

Hi Chris, I've posted this before, but it's worth saying again. I use the PocketPC version of Lady Heather on an IPAQ. These are available for next to nothing on Ebay and can run in a dock on the bench or you can gut it and embed it in a cased Thunderbolt. worn out batteries are not an issue as

Re: [time-nuts] RFTGm-II-Rb - can you gps discipline it without the XO module?

I don't think the rubidium module for these systems can be disciplined. I think they were only intended as a backup if the XO section or GPS failed. The XO section does discipline but I don't know the details. I'm not sure of the model number, Lucent had several variations on the same theme

Hi Rex, I don't think the rubidium module for these systems can be disciplined. I think they were only intended as a backup if the XO section or GPS failed. The XO section does discipline but I don't know the details. I was hoping since the rubidium module had a light for GPS and an input for

Re: [time-nuts] RFTGm-II-Rb - can you gps discipline it without the XO module?

Hi So your Rb is 0.71 ppb off frequency. That's far enough that's it's worth adjusting. You should be able to get it 10X better than that without a lot of work. Bob On Aug 15, 2013, at 6:02 PM, Alan Kamrowski II ala...@earthlink.net wrote: Hi Rex, I don't think the rubidium module for

Hi Bob, Is it 0.71 ppb off or 0.071 ppb off? This is how I calculated it: 13939010/13939 = 1000.000717411579022885429371 answer/1000 = 1.00717411579022885429371 answer-1 = 7.1741157902288542937083004519693e-11 answer*1e9 = 0.071741157902288542937083004519693 Thanks, Alan
