Duaine, I use the RCT (www.reyburn.com Reyburn Cyber Tuner) on a handheld pocket pc. When using RCT you have to first get the proper tuning curve for the piano you are working on. This can be done by using the learn mode or by pulling up a previously saved tuning curve from the files. I now have enough pianos in my tuning files that 95% of the time I don't need to do the learn mode. The learn mode is easy enough: you just sample the A's, A1 through A5. Takes two minutes Once you have the tuning curve you set the RCT for pitch raise mode. In doing so you have to enter the lowest plain wire note so RCT knows where it is. Plain wire notes require greater overpull percentages. You start at A0 and work your way up to the top, tuning unisons as you go. Every time you advance to the next note RCT records the initial pitch, averages it with the previous 4 or 5 notes, calculates an overpull and then shifts the target. This all takes place in about a quarter of a second. You then tune the first string of the note to the shifted target, then the rest of the unison to the first string. Normally I work with 2 rubber mutes all the way up the scale where there is room. In uprights past the treble break I'll use a single mute: either a cut down rubber mute or a cut down split mute. Then you set the RCT for normal mode and go back and check, especially the octave above the bass break. Depending on how nice you are wanting to leave the piano will dictate how persnickity you get in doing the final touch up. Normally on pianos out 20-30 cents there will be a dozen or so notes that I clean up. Total time spent: 45-60 minutes. Charges: $20-$30 extra. On pianos out 100-200 cents I may need to do two full passes and clean up a dozen or two notes on a third pass. Total time spent: 60-90 minutes. Charges: $65 extra. Normally (unless it is a piano I regularly tune) when I have to use pitch raise mode I charge $1 extra per cent out (using an average of the worst octave), up to a maximum of $65 extra. I hope I didn't leave out any steps you were looking for. Don't hesitate to ask if you need anything clarified. I love using RCT for pitch raises.

Mutes - procedure ? Strip - procedure ? Start at the bass and go up ? Start in the middle and go down first ? up first ? Looking for exact procedures - as if teaching a class.
