Hi,
I have Tripple-P TXU-1256 repeaters and they did run fine, but...
I bought one unit from a friend and three more from the museum. Initially they function properly.
the setup is:
txu-1256 (adjusted to rx @ 431.725, tx@439.325)
original duplexer replaced with an arreal facilities one
txu-nf-out -> wx-steuerung (nf out) -> lingua 12 -> transformer1
wx-steuerung (beep, taken from cpu) -> transformer2
transformr 1 & 2 -> txu-nf-in
the transformers are needed as I did bypass the lingua for the cw beacon and roger beep from the wx-control board and the impedances did not match...
this setup runs very nice for about three month...
after approximately three month the system suddenly fails. the green O.K. LED starts flashing. On plugging the control pc all settings appear to be forgotten. After reprogramming the system will work for a while but during the operation it will reboot all over sudden. without the control pc connected the settings are lost again. if the control pc remains connected with the software running the system comes back after a while.
I also found out that there appears to be some sort of dying process as follows:
On powering up the "O.K." LED takes longer and longer to stay on...
I had this issue with two units now. The last one died saturday evening. I am a little shy of setting up number three and maybe ruin it the same way
Does anyone have an idea what is going on?? Hints? Experiences?
