I have an extra working Kenwood R-5000 recriver, it has the optional YK-88SN, 1.8 mhz SSB filter, and the manual (copy). On a 1-10 scale it is an 8. A money order for $530 and I will pay the shipping. It you are interested, please e-mail me direct. Many Tnx----Doug ddswl at centurytel.net PS; I THINK that I have the original box.
