Terry, There was an article in QST sometime last year in the 'HINTS AND KINKS' column. The article as I remember it was step by step. Perhaps you could get someone locally to do the installation for you. 73, Vince Santis, N1VS Winsted, CT -----Original Message----- From: Terri Pannett [SMTP:[log in to unmask]] Sent: Wednesday, March 14, 2001 1:59 PM To: [log in to unmask] Subject: Kenwood TS570D lithium battery Hi, Everyone, The data doesn't stay in my Kenwood TS570D and I ordered a new lithium battery. Does anyone know if hams can install these batteries or does the radio have to be shipped to Kenwood? Terri, Amateur Radio call sign, KF6CA. Army MARS call sign, AAT9PX.
