[time-nuts] military frequency standard pin out??
Hello Folks, I found in my collection a frequency standard that I acquired mil surplus at one time. The model number of 2N6625-078-4718 internet search yields nothing on this number. The unit is a common looking one , approx. 4 x 3 x 4 with an aluminum cover that comes off. The cover has the layout of the parts. The connector has 6 coax outputs into a D type connector. It appears 3 pins for power 1 is ground that easy to see but the others are 2) a red white and black that leads to the circuit board 3) and a brown white and black also leads to the circuit board. I would like to fire this up, but not burn it up. Any ideas? Thank you Paul A.

[time-nuts] USB Interface, legacy Software
I have a software program, no longer supported, which requires two RS232 serial com port interfaces, one to communicate with a sensor (signal strength collection receiver) and the second to accept serial data from a GPS. The laptop computer I am using has only one RS232 Com port which I must use with the sensor due to incompatibility with USB to serial converters I have tried. This leaves the USB for the GPS input. I am assuming that the GPS string should be acceptable as I do nor believe the software needs to handshake with the GPS. I would like to use a Delorme USB type receiver on the USB port. Can anyone recommend a software add on that will make this type receiver appear as a standard RS232 Com port to my software?

Re: [time-nuts] USB Interface, legacy Software
Hi My guess is that your software isn't just looking for a serial port. It's also looking for specific strings back from the GPS. Depending on what you attach, it may or may not give you the strings you need. If you are doing timing, a USB interface will be a major headache. Most sensor = usb issues are a result of the sensor getting a supply voltage from the serial port. The USB serial chips often don't have enough power to do the trick. There are various outfits that sell multi port USB interfaces that allow you to attach a power dongle to them. Often these are the only thing that will get a setup like yours to work.

Re: [time-nuts] USB Interface, legacy Software
I've been using Delmore GPS receivers for several years. They have a driver (http://support.delorme.com/questions.php?questionid=24 http://support.delorme.com/questions.php?questionid=24) for Windows that will install it as a standard serial port sending NMEA messages. The older serial Earthmates can be powered by applying 5 volts to pin 9 (return to pin 5). As long as the software communicates thru the standard Com drivers, Serial to USB converters should work OK. I've been able to tap the USB 5 volts and power the serial device (as above). Just look for a converter that is in a hard plastic case, not molded. If found the Gold-X adapters are pretty consistent working with legacy software.

Re: [time-nuts] FCC Chair Talks Spectrum, Gets GPS Letter
Personally, I would be opposed to LS even if they *did* offer to replace every GPS in the world at their cost. The real issue here is more fundamental - if you are going to allow people to operate high power terrestrial based transmitters in a designated satellite downlink band then what is the point of having spectrum planning at all? I suppose you can't really blame LS for trying it on - the real fault lies with the FCC for not shooting the idea down completely when it was first suggested.

Re: [time-nuts] FCC Chair Talks Spectrum, Gets GPS Letter
Pete wrote: I suppose you can't really blame LS for trying it on - the real fault lies with the FCC for not shooting the idea down completely when it was first suggested. The regulatory notion is ancillary terrestrial component (ATC). Its original purpose (conceived in the early '90s) was to allow satellite operators to fill in dead zones. Satellite radio (SDARS) operators began deploying ATC in the late '90s and early '00s. The SDARS licensees seriously abused the privilege (causing extensive interference to users of the adjacent WCS spectrum), and it has been downhill ever since. I thought it was a bad idea in 1992, and subsequent experience has only strengthened my view. As I have said before, the current FCC has the (I believe) unfounded notions (1) that an exploding need for additional mobile broadband spectrum will continue unabated for at least a decade (based on the figures for the first couple of years of data, which are inevitably way higher than ultimate demand for any new service), and (2) that providing more broadband spectrum is critical to the US pulling out of the recession. Accepting these (I believe) mistaken premises, the FCC is in an absolute panic to increase the supply of mobile broadband spectrum by 500 MHz nationwide. And good decisions are rarely made by bureaucrats in a panic. The decision to encourage terrestrial use of the MSS spectrum is just one of many examples. As a reality check on my skepticism regarding the FCC's conclusions, or at least the practicability of fulfilling them: If you accept the FCC's demand projections for mobile broadband spectrum, it is clear that even 500 MHz of additional spectrum would not come anywhere near fulfilling the rising demand over the next 5 years. That would take more like 3-10 GHz, depending on other assumptions. But there is simply not that much spectrum physically suitable for mobile broadband use, even if you allocate it all to wireless carriers -- frequencies below about 500 MHz require antennas too large for practical handsets, and frequencies much above 2 GHz do not carry far enough in open country, or penetrate sufficiently into buildings, natural canyons, or urban canyons, to work acceptably. All that said, LS's engineers should have (and may have) foreseen the devastating effect the use of ATC on their particular L-band spectrum would have on GPS as we know it, and LS management should have known that their plan would ultimately fail. But the prospect of making a windfall of many billions of dollars apparently blinded them (or, in their minds, justified the risk). But in the end, LS took the risk and LS should bear its losses and quit trying to stick US taxpayers with it. They paid fair prices for MSS spectrum that can still be used for its intended purpose, or sold. No loss, no foul.
