You want to use it in a well ventilated area. It heats the board to be reworked from the underside to close to solder temperature, then uses infrared from the top side to push the temperature for the part in question above solder melting temp., and sometimes things close by. The underside heater is covered with silicon rubber, and gives off strong odor when hot. Hot PCB boards give off strong odors, and of course, you are melting solder and flux.

Re: [time-nuts] Loran
Does anyone know if they are using original antennas for chains that existed during the heyday of LORAN C? I remember driving past the tower at the Seneca Army Depot in Romulus, NY , and I was in awe of the size of the tower. I know the Coast Guard, then Homeland Security had control of the site. I am not sure if the tower is still there since some of the sites were decommissioned. I was wondering if they will be using the Master/Slave system, or do they have a new way to triangulate? I know the worry of GPS jamming has caused a lot of worry. I was wondering if cell sites that absolutely need super accurate timing will have LORAN as a backup timing source? I know if they lose GPS, they lose their ability to hand off to adjacent working cells (Island Cell Effect?).

Re: [time-nuts] Loran
Gerald The new roll of the thing called LORAN has nothing to do with location any longer. But we all still call it LORAN. Old habit. Its new purpose if the government funds it is PNT dissemination along with some ability to send messages. In theory to backup GPS for timing. UrsaNAV did pick up at least 1 facility in NJ and they might have purchased another 1 or 2 but have no need to purchase all of the old sites. They produced a ppt that showed as little as 1 site would cover the US and two really would fill in the blanks. some place semi-central. For us time nuts even the single central site would be useful as long as they stick to the current transmission format. Internationally they might have to stick to this modulation method since Europe uses the frequency for true eLORAN. I don't really know. But I am not complaining as the old receivers have all of there green lock lights on at 1745. Guess no one went for beer. Though they might shut down at utc I have seen them do that. The benefit of all of this is as an alternate frequency source that in Boston has always been far superior to the 60 Khz WWVB transmission. In fairness to WWVB if I had a magical processor as good as the LORAN receivers/processors, maybe it would do far better then what I see on the wwvb receivers I have. I just do not believe it would equal the LORAN quality. Currently all of the receivers are saying the signal strength is the same as last night. Though in actually listening to the signal I have a healthy dose of man made noise today.

Re: [time-nuts] Loran
Bob I agree with your comment on the location. Though I like nj because its a lot closer. ;-) Jerry as far as your stuff goes. It might just need a good old boat loran c antenna and preamp. Heavens knows if they exist on ebay these days. The preamps are also pretty simple a fet and transistor buffer. The antenna can be a piece of wire say 20-30 ft vertical. Now the hard part. If you have no instructions for operating the rcvr you just have to tinker. They almost always need the gri plugged in 87900 in this case. This really is the point that it gets hard. On the old austron 2000s you had to have a scope to align stuff it was a somewhat manual rcvr. However there were advantages also. If you don't have semi automated rcvr and no op instructions thats going be fairly unrewarding. But good luck experimenting.

Well its past 8 pm and loran is still on. About a 2 years or so ago at the MIT flea a fellow dumped a number of loran c things. Some I did not recognize. I picked up 3 austron 2100 and F class units. Also a test simulator. One had a GPIB interface. So just fired that unit up and it locked right away. Looks like far sooner than later I will need to test the command set to see what info it will give me. Should be fun. Though not the priority this second.

On the old austron 2000s you had to have a scope to align stuff it was a somewhat manual rcvr. However there were advantages also. If you don't have semi automated rcvr and no op instructions thats going be fairly unrewarding. But good luck experimenting.

While doing that I came across a Loran C timing receiver and a Loran C simulator that was made by a company ( can't remember the name - wasn't Austron). Never could figure it out, or find the company, but I still have both items. maybe I can still figure it out since it was just a simple 100KHz receiver with timing circuitry.

Old habit. Its new purpose if the government funds it is PNT dissemination along with some ability to send messages. In theory to backup GPS for timing. UrsaNAV did pick up at least 1 facility in NJ and they might have purchased another 1 or 2 but have no need to purchase all of the old sites. They produced a ppt that showed as little as 1 site would cover the US and two really would fill in the blanks. some place semi-central. For us time nuts even the single central site would be useful as long as they stick to the current transmission format. Internationally they might have to stick to this modulation method since Europe uses the frequency for true eLORAN. I don't really know. But I am not complaining as the old receivers have all of there green lock lights on at 1745. Guess no one went for beer. Though they might shut down at utc I have seen them do that. The benefit of all of this is as an alternate frequency source that in Boston has always been far superior to the 60 Khz WWVB transmission. In fairness to WWVB if I had a magical processor as good as the LORAN receivers/processors, maybe it would do far better then what I see on the wwvb receivers I have. I just do not believe it would equal the LORAN quality. Currently all of the receivers are saying the signal strength is the same as last night. Though in actually listening to the signal I have a healthy dose of man made noise today.

I remember driving past the tower at the Seneca Army Depot in Romulus, NY , and I was in awe of the size of the tower. I know the Coast Guard, then Homeland Security had control of the site. I am not sure if the tower is still there since some of the sites were decommissioned. I was wondering if they will be using the Master/Slave system, or do they have a new way to triangulate? I know the worry of GPS jamming has caused a lot of worry. I was wondering if cell sites that absolutely need super accurate timing will have LORAN as a backup timing source? I know if they lose GPS, they lose their ability to hand off to adjacent working cells (Island Cell Effect?).

Does anybody know the proposed ERP on the new system? Some of the master’s on the China chains are pretty high power if I remember correctly. This powerpoint presentation http://www.tinyurl.com/l2humtb says the NL40 transmitter they just bought is 300 kW. I thought a lot of the Asian chains, including China, used Megapulse equipment like the US. I think Megapulse did use to say their transmitters were multi-Megawatt, but I can't check that since http://www.megapulse.com now goes someplace else. I wonder whether the last bit means that Megapulse is now out of the transmitter business for good, or if Ursanav's infatuation for the Nautel transmitters is just a passing fancy while they complete their vertically integrated monopoly.

Re: [time-nuts] Off Topic Sortof: Board Rework Stations
Thomas, You can say that again. Maybe this can help start a renaissance of sorts of garage started companies again in this country. To be able to rework BGA's for ~$200 - that is great.

It basically works as represented. It takes some skill to run, and takes some time to develop the safe settings for soldering different sized items. It puts out a tremendous amount of infrared heat, and you can melt things if you are not careful. For instance, it will melt plastic connectors close to the part being reworked. You want to use it in a well ventilated area. It heats the board to be reworked from the underside to close to solder temperature, then uses infrared from the top side to push the temperature for the part in question above solder melting temp., and sometimes things close by. The underside heater is covered with silicon rubber, and gives off strong odor when hot. Hot PCB boards give off strong odors, and of course, you are melting solder and flux. So, good ventilation is highly recommended. You will need to practice on a few scrap boards before you try to solder something valuable. In the hands of a skilled operator, it does beautiful work. --- Graham == On 11/13/2013 9:00 PM, John C.
