Summary 0000114: The TP of BX(MFFE-07) is unstable at the beginning of HA.
Description 20090323:
The TP of BX(MFFE-07) is unstable in all bands, but only at the beginning
of HA. The problem can be seen at Lband and 6cm. Harm-Jan will look at it.
Additional Information 20090609:
Op dinsdag 9 juni is de coaxbekabeling op de uurhoek van RTB door Peter
gerepareerd. De trekontlasting van de coaxbekabeling was losgeschoten,
daardoor kwam er mechanische spanning op de connectors te staan waardoor
het signaal van IFX onderbroken werd.

 Op woensdag 15 april heb ik de IFX kabel van RTB gewisseld van WIT op de tel. aansluitkast naar GROEN.
Resultaat is dat de uitval van het signaal bij ongeveer -85 gr. wat minder diep is als bij kabel WIT maar nog
steeds aanwezig. Waarschijnlijk is er toch een probleem met de poolasjumper van RTS.
Zie meting 10901723 en ...1705 de TPON plot.
