Was doing a search for Lucent RFTGm-II-XO looking for alternates to the $150 solution. A 10 Mhz mod popped up. http://telcodata.us/~myself/Lucent-RFTGm-Modification.pdf Looks simple enough and I have not validated anything. Regards Paul WB8TSL

Hi Another alternative would be to AC couple into a NC7SZ125 (using a 0.1 uf cap and a pair of 100K resistors )and take the output off with a Tee filter (using two 1.5 uH coils and a 270 pf cap).

Hi This is a branch thread that never got it’s title changed to drop the KS-24361 part of it. More or less it’s “compare the older KS boxes to the newer ones”.

I just saw the picture of the units front panel and it looked the same. Oh well.

Hi Lucent has been putting GPS based Radio Frequency Timing Generators (RFTG) into cell sites for a long time. They all have the 15 MHz and pps outputs in common. Lucent also seems to like one paint color and an approximate size. For what ever reason (because they can?) the model numbers and internal designs change from time to time. For quite a while they really liked the idea of running Rb’s in cell sites. Looking at the latest batch of parts, that seems to have changed around 1999. Lots of generations of very similar looking boxes with very different stuff inside each of them.

And I am the happy owner of 4 or 5 of the $25 RBs. Hey they are old but you can recover them with the old heatgun trick. That said glowing things like those do tend to wear out. I could see why they moved away from them.

Hi So far, I have not found any of the Rb’s that came out of the KS boxes with troubles. The ones I got and pulled from boxes myself all have worked fine. The units that got pulled on the other side of an ocean, not so much. There have been a couple of them with issues. What ever they go through getting shipped overseas and salvaged, it’s not doing the parts any good. That’s one of the reasons getting the newer design KS boxes NIB has a lot of appeal. There are infant mortality reliability issues to deal with on new stuff. I’d rather have those issues than end of life and corrosion.

On the old telco RBs $25 they all worked, but were down on lamp life. So the first one chosen ran for 3 years and then started blinking out. Replaced it with another. That first one is the one I used the heat gun on and is again operable with what appears could be good lamp life.

Hi So far, I have yet to have one of the Rb’s die (of the ones that worked when new to me). The magic “lamp voltage” on the Efratom versions clusters in two groups. That seems to be related to some sort of production change rather than better performance on the (slightly) newer parts.

Unless you have a way to know what they are doing. You won't know if they are failing. The initial sign is that they wink-out and restart. You will spot it as your gear going nuts for a bit and then magically locking up. Also as an approx lamp V in the 2-3V range. Thats really a gross figure I can't swear thats EOL. But its some place close to that. As such I installed the Rb winkOmeter on my unit.

Hi I normally keep a watch on the lamp voltage (or what ever it actually is). I was once told by somebody who should know that you simply watch for it to drop. When it starts going down a couple volts, that’s when you should start looking for a backup. It may run for months after it starts to drop. It may run for weeks. There apparently is no good way to be sure. On a part that starts at 6 to 7 volts, that would equate to something a 3 to 4 volt limit.

I do agree its subjective. But my gut says bad is 2-3V I know they seem to run above 3. But whatever. When the blinkOmeter counts I am screwed. :-) Time to get the heatgun. Regards Paul.

Hi The heat gun approach assumes that the fault is a blob of metal that is stuck in a bad location in the bulb. Unfortunately there are a lot of different ways these beasts can die. The repair guys who should know always claimed that bulb issues were < 30% of the issues they saw. That was on an earlier generation of Rb’s but I suspect it applies. None of the ones I had arrive DOA were bulb problems.

Bob Absolutely lots of ways to die. Such as bad caps, bad variable cap, resistors that are cooked..... I am pretty good with all of those and have experienced most of them. But then comes the point of the dirty bulb and it doesn't have to be the blob. Though you will find the blob most likely with the dirty bulb. The darkened window cause a loss in signal and ultimately loss of lock. The heat gun clears both up.
