I found a solution the the "FT-1000MP RX-Clarifier Check" posting of 19-07-1998.
The problem is the rotary encoder of the Clarifier function. To smoothen rotation, the manufacturer of this type of encoder,
puts some grease into the shaft of the encoder. Due to extensive usage, this lubricant comes into the encoder itself, where
it flows between the fixed contact pads and the rotary contacts (you can compare it to the wiper contact of a potmeter). As
the lubricant is not electrically conducting, some contact points (representing digital values) are not detected by the digital
control.
Solution is simple:
1. open TRX (both covers)
2. remove all knobs and dials from frontpanel (only those needed - it'll point itself out)
3. tilt front panel towards you and locate little PCB (printed circuit board) holding the Clarifier encoder
4. loosen connectors + screws and pull out the little board as a whole
5. on the encoder (shaft facing upwards) you see 4 clips; bend them 90° upwards and CAREFULLY pull away the upper
part
6. now you see a black disk with metallic contact pads, and in your other hand, you see three brittle springs, all covered
with grease.
7. clean both parts thoroughly using Q-tips with alcohol (or something similar not agressive to plastic), but BE
CAREFULL not to bend the springs.
8. now assemble everyting back together by following above steps in reverse order, but take care of the springs when
closing the encoder!
Should work 100% ok! Good luck!
