For sale is a set of filters for most late model Kenwood radios. I have the YK-88C-1 CW filter and the YK-88SN-1 Sideband filter. Pulled these from my TS-850 since I don't use them. Both are working and will be carefully packaged and shipped. Prefer to sell as a pair. I also have a sideband filter from my 570 on a separate thread. Price for the pair is $150 Shipped. PayPal is my preferred method of payment.
