Re: [time-nuts] One man's noise is another man's signal...
This is an interesting use of GPS, I had never considered the Aurora or solar storm angle before. However, I am aware of the use of ionospheric scintillation and TEC measurements for ionospheric research and also for the study and detection of earthquakes. Canadian High Arctic Ionospheric Network (CHAIN) uses this technology http://chain.physics.unb.ca/chain/pages/gps/ and a couple of links about the earthquake angel: http://demeter.cnrs-orleans.fr/dmt/doc/workshop2011/10_Vishal_Chauhan.pdf http://demeter.cnrs-orleans.fr/dmt/doc/workshop2011/12_O.P.%20Singh_Agra.pdf I have been pondering how I could use as is or modify one of my GPS receivers to make these sorts of measurements. The CHAIN gps receivers use a OCXO but haven't figured out how to apply that to one of the GPS receivers I currently have or even if I could. I have also been pondering whether I could approach from a different angle by using the range correction values provided Differential GPS (DGPS) radio beacons which broadcast range correction values for use with DGPS capable receivers. Seems to me that the Ionospheric effects on the GPS signal is reflected in the range correction values and it should be a matter of working backwards.

Re: [time-nuts] PRS10 Lamp Module Needed
Hi Bruce, Thanks for your reply. I'm aware that the tantalum capacitor is on of the weak points of the RF amplifer that excites the lamp. After testing the unit and using the monitoring software available I found that the problem relies on that specific part of the circuit. In fact the RF unit was burned like the tantalum capacitor you are refering. Last year I rebuild that circuit section interely with high quality components with good temperature reliability replacing the RF transistor, porcelain capacitors and metal film resistors. The lamp was heated up as well. The unit worked for about 6 months. Now I found again that the signal strenght received by the photocell has droped below the acceptable value so there is no more I could do except to send it back to SRS for lamp replacement... Regards, Vasco Soares - Original Message - From: brucekar...@aol.com To: time-nuts@febo.com Sent: Wednesday, August 13, 2014 3:21 PM Subject: [time-nuts] PRS10 Lamp Module Needed Vasco, As Brooke said it is unlikely there are spare PRS10 lamp modules found outside the manufacturer. The probable reason is that when the PRS10 units are assembled certain adjustments to the firmware are necessary such as the starting level and final bias of the FET oscillator transistor. As far as I know, SRS has not revealed how to access to these factory settings. It might be possible to repair your lamp assembly. One point of failure is the Tantalum capacitor found in the lamp assembly. Another possibility is that the heater resistor may have changed value or opened. Although it looks daunting, it is possible to replace the FET power transistor; however, after replacing the transistor in one unit, I found the transistor's characteristics were a little different than the original and the operating parameters were not right. I considered adding some external resistors to shift the biasing, but finally decided to try another transistor with somewhat different characteristics. But in this second try I damaged the board. If the rubidium bulb assembly is suffering from old age, it might be possible to improve it with a heat gun as discussed on this listt several times in the past. The bulb is cemented in place, but it might be possible to remove and replace it.

It usually takes 2-3 weeks to get boards back once sent to the fab (in China). Supposedly the boards that I am having them do for another project should be here today and I can verify their quality. I also laid out a 20 pin extender to connect the input board to the front panel, but I don't think those would be too useful. You can extend the other side of the input board/front panel using a 36 pin extender. A while back I had the idea of doing a replacement board for the custom HP input comparator chips that fry is you overload the 5370 inputs. Need to start looking at what that would take... there are two different versions of that chip/input board.

[time-nuts] HP5370 extender cards?
Yes, can ship world wide. Not sure what the postage will be, but should not be too bad. I'm leaning towards a 3 card set as the standard. Two of the 36 pin extenders and one of the 44 pin. There are a couple of other misc boards in the machine with different pin counts (oscillator, oscillator power, oscillator buffer) but those three should be able to handle most of the work. If you really needed to extend the 30 pin oscillator or buffer cards, you could hack up a 36 pin card. I got my other projects' boards in from China today. They look good. Now to get the TM500 and 5370 boards on order. ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
