I have also repaired a keypad before using parts from an old calculator. If you have something on hand to sacrifice give it a shot, if not get a repair kit. |
| Mr Smiley:
I repaired my next door neighbours sky remote a few years ago, as in your case, the conductive rubber had perished on his most used button. A quick fix was some silver foil ( Aluminium cooking foil ) and a paper punch. punched out a small round piece and glued it onto the back of the button, still going strong :-+ :) |

I dont expect I'd have such serious 1024 WEEK uptimes, thats like 18+ years... as for time, its fine on this end --- End quote --- Hi That looks ok. Actually the problem manifests its self like a Y2K bug in most systems. The date magically leaps back 1024 weeks when the "expiration date" on the GPS module firmware hits. The modules in some of these gizmos have firmware that dates to the mid/late 90's even if the device firmware was done later. It's well worth checking (as you have done). Yes you could write firmware that was a bit smarter, unfortunately a lot of people did not. You can also do a better job with the GPS data. That change will be implemented with the launch of some new sat's "real soon now" (first it was 2005 then 20010 then 2015 then 2018 ...). Bob |

Got one of those button replacement kits from ebay for $2 or something. Worked like a charm. Now my goal is to get 100ft of LMR-240 with a male BNC on one and and male TNC on the other so I can run it to the roof. I should probably run some string to make sure 100ft is sufficient. I think it should be. Right now its serving time as a startum 1 ntp server to everything on the network. very cool! |

You can likely get RG-11 cheaper as well. For a GPS receive antenna it's more about loss than match. Neither end (source or load) may be well terminated. If it's outdoors, make sure you get the outdoor rated stuff. (still cheaper than LMR). Bob |
