Some good points, just needed another brain to talk with. I will try a couple of your ideas. On the 834, I'm using pin 13.

This is why there's a PTT Priority field. You've got "LW" so the local mike has priority followed by the wire line. If this does operate as I think, once the mike PTT line (TP9) gets grounded, this shuts off any other audio source and routes mike audio through the station. > > You didn't specify the pin number on U834 where you're feeding TX audio into. > > I think you're mixing and matching several incompatible signals here, while also trying to interface the CAT controller to the station. > > I'd connect a scope to U832 pin 11, feed a signal into the receiver with a valid PL, then ground TP9 and see what happens. If the COR signal goes away, that's one problem. If not, then many of my assumptions above are incorrect. Also check the summed audio output at TP1 and make sure receive audio stays there with TP9 grounded. > > You might consider connecting the COR and CTCSS inputs on the CAT together. I don't recall if switch or zone settings deal with whether you are using or not using CTCSS.

There are a couple of articles on the web that deal with interfacing and programming CLB stations. I haven't checked them recently but perhaps these will give you some additional choices. > > Bob M. > ====== > --- On Mon, 3/2/09, svfdcook <rsc...@...> wrote: > > > From: svfdcook <rsc...@...> > > Subject: [Repeater-Builder] Re: MSF5000 CLB Eprom Programming Template > > To: [email protected] > > Date: Monday, March 2, 2009, 12:02 PM > > Here are my current connections and programming. > > Programming has > > changed a couple of times as I try different things. > > > > Connections: > > > > CAT-400 (J4) CTCSS (Not Used, since my COS only goes high > > with > > proper PL. > > CAT-400 (J6) COR (COS) to SCM Board, U832 pin 11, active > > high > > CAT-400 (J10) PTT to SCM Board, Test Point 9, active low > > CAT-400 (J11) TX Audio Out #1 to SCM Board, U834 with 18K > > 1/4 watt > > resistor > > CAT-400 (J13) RX Audio In #1 to SCM Board, J800, Pin 38 > > CAT-400 (J14) Shield Ground to SCM Board, J800, Pin 37 > > CAT-400 (J14) Ground to SCM Board, J800, Pin 40 > > > > Programming: > > > > #1 Model C74CLB7106A > > #2 Number of Channels = 1 > > #3 RF Frequency Infor / Range Checking Desired = Yes, > > Channel 1 = RX > > Freq = 448250.00 KHz, Channel 1 = TX Freq = 443.250, Update > > Tuning > > Channel? = Yes > > #4 Coded Squelch Info / Channel 1 = TX-PL = 3A, Channel 1 = > > RX-PL =3A > > #5 P-T-T Time Out Timer / Channel 1 = LIN-TOT = 60.0 > > Seconds, > > Channel 1 = LOC-TOT = 60.0 Seconds, Channel 1 = RPT-TOT = > > 180.0 > > Seconds > > #6 RPTR Drop-Out Delay / Channel 1 = RPT-DOD 0.0 Seconds > > #7 P-T-T Priority Onfo / Channel 1 = LW > > #8 Repeater Control / Channel 1 = RPT Act = SC, Channel 1 = > > RPT Hold > > = SC > > #9 RCVR Audio Control / Channel 1 = RCVR Audio = SC > > #10 TX Audio/Data Mixing / Channel 1 = Mix LIN with Data = > > No, > > Channel 1 = Mix LOC with Data = No, Channel 1 = Mix RPT > > with Data = > > No. > > #11 Auto ID Callsign = Left Blank > > #12 Alarm Tone Routing / Channel 1 = Over the air = > > Enabled, Channel > > 1 = Over-The-Air = Enabled, Channel 1 = Over-WIRELINE = > > Enabled > > #13 DC Remote Currents = Default > > #14 Mux-Bus Power-Up = Default > > #15 Spectra-TAC Info / MCS Station Info = Spectra-TAC > > Station Type = > > Base > > #16 MCS Station Info / MCS Station Operation = No > > #17 RA Station Info / On-Cabinet Repeat? = Yes *This has > > been > > changed both ways (Yes and No) > > #18 Wireline Duplex / Full Duplex = No > > > > Thanks In Advance > > Ray > > KE5VJH > > rsc...@... > > > > > > --- In [email protected], "Bob M." > > <msf5kguru@> > > wrote: > > > > > > > > > If this was a stand-alone repeater, instead of a > > base-station, I'd > > think you have the repeater-activate and repeater-holdin > > parameters > > set differently, such that it needs carrier and PL tone to > > bring up > > the repeater but the holdin is missing or OFF. > > > > > > However, in a base-station configuration, the only > > field that has > > meaning is the receiver audio control / activation. > > > > > > I'd suspect the signal polarity and/or level > > feeding the CAT > > controller is incorrect or needs a pull-up on the input. > > What points > > in the MSF are you using to supply the COR and CTCSS input > > signals? > > > > > > Is the CAT set up to require CTCSS?
