Vern, The TS64 will do encode and decode at the same time and the unit for the MII from Comm Spec can do this. Wheather as comes not sure.
I think the MII CG unit did only encode OR decode looking at the PTT signal and switched. So I think the decode and encoding of the TS-64MASTRII will do as you want, but definitely can be made to do what you want. It plugs into the MII mobile. 73, ron, n9ee/r >From: [EMAIL PROTECTED] >Date: 2008/03/05 Wed AM 07:00:25 CST >To: [email protected] >Subject: Re: [Repeater-Builder] mastr II repeater tone (CG) board. > >I wish I had read this before I ordered the TS-64MASTRII >yesterday.
