I replaced all four encoders ( with help from my friend ) couple of days ago. It was quite a job as the whole front panel has to be taken into pieces and DSP boards has to be taken off. A good SMD rework station is recommended to clean through holes + experience in rework not to damage foils in PCB. New encoders are bit thicker so height difference has to be taken into account while assembling .
New encoders work smooth and great. One notice, be careful when taking off the knobs as at least RIT encoder is not having nothing else than small soft metal clips holding it together ( Encoders metal nut has been left out as there is no room or thin enough nut was not available at the time mine was built ) BR Olli OH6CT > -----Alkuperäinen viesti----- > Lähettäjä: Elecraft [mailto:elecraft-boun...@mailman.qth.net] Puolesta > SA2CIR > Lähetetty: 30. joulukuuta 2014 23:19 > Vastaanottaja: elecraft@mailman.qth.net > Aihe: Re: [Elecraft] K3 front panel encoders > > Thanks for informative pictures and writing!
