Pin 1 (SQUELCH OUTPUT)of the DB-9 SUB connector is listed as: "active high", yet when I check this pin I measure 5 VDC with squelch close and goes to 0.06 VDC with squelch (RX Siganl) open.
On other point to note, this same Pin 1 also goes low when the radio in in TX mode (PTT). This is an issue when connectiong this radio to a controller, as not only does the PTT LED come on, but also the COS! I have written Vertex about this issue as there maybe a jumper on can work around this, but have received a reply thus far. 73, Lorne VE1BXK --- In Repeater-Builder@yahoogroups.com, "na6df" <jammerd...@...> wrote: > > Yeah, I have a bunch of the vx2000's.
