I have owned 4 Kenwood 570dg and 3 had this common encoder fault, a temp fix was to pull the knob off squirt in some switch cleaner and attach a battery drill to the shaft and give it a quick spin, it did temporarily fix the fault.

Just to let you know you that you can fit the following part as an alternative with some minor modifcations

https://www.digikey.co.uk/products/en?k ... 02-1786-ND

thanks to ycarc@axion.ca for the advise and instruction on fitting (below)

Enclosed are 3 pics about changing the MULTI encoder on a Kenwood TS-570

The first pic shows side by side the Kenwood encoder and the digikey replacement

Let's designate the pins from left to right as pins 1, 2, 3, 4. on the Kenwood encoder, that goes to holes 1,2,3,4 on the board.

Pin no 2 is Not used by Kenwood.

Carefully unsolder the Kenwood encoder cleaning the pin holes.

Once you have received the replacement encoder 3 pins,

From left to right pin 1 goes to hole 1 on the board, hole 2 is left unsused, pin 2 on the replacement encoder goes to hole 3 on the board and pin 3 of the replacement encoder goes to hole 4 on the board.

Prepare the replacement encoder by first removing a protuding tab on the top shaft side.

Then cut the 3 small pins on the digikey encoder and solder 3 wires as per second and third pics.

Note the wire on pin 2 is bent and aligned to enter hole number 3, while the wire on pin 3 is slightly bent to align with hole number 4 on the board.

Solder in place and you're done.

The new encoder is of a much better built and the click is positive.

I've ordered this part and will hopefully be able to make the swap sucessfully.

Thanks
