TS-870S review

Jim West24 february 2022

I bought a Kenwood TS-870S in June, 2002, and it was my primary radio for over 10 years. I never had any problems with my old Kenwood, and it worked great. I really like my Kenwood TS-870S, and still have it, and it stills works as good as new. Occasionally, I still work ham stations using the Kenwood TS-870S, and they sound great.
