Re: [Repeater-Builder] need Mitrek
First get yourself a Syntor X make sure it works on the Freq. it is on then I can program an EEPROM for your freq. and swap you EEPROM's Or if you have a programmer I can send you the image and you can program it yourself. tom -Original Message- >From: [EMAIL PROTECTED] >Sent: Feb 26, 2008 2:31 AM >To: Repeater-Builder@yahoogroups.com >Subject: Re: [Repeater-Builder] need Mitrek > >Tom, >Sounds like that might work well for me.

[Repeater-Builder] Mastr II white noise on transmit
Fired my UHF Mastr II up again and noticed excessive white noise (I think) in the transmit audio even on a dead carier. It is the phase modulated exciter tuned down in the 442 range. Is this just the nature of the beast? tom n8ies

If duplexer in and tx output are not exactly the same then adding or subtracting cable lengths can change the vswr the tx sees. I have seen this in real life, I do not have a network anylizer so I can not be sure what was happening but to make the tx happy some cable was added until the reflected power was minimized and the desense went away like magic. I think the manual that came with my Wacom duplexer talks about this phenomena. tom
Re: [Repeater-Builder] Re: Anyone ever interface a CSI TP3200 tone panel to an external controller?
He only wants encode decode functions so it basicly hooks up just like a ts-32 or ts 64. It is explained in one of the ACC manuals about how to hook up a com-spec tp-3200 controller. I think it was in the ACC 850 manual you should be able to download a copy on RB. I think it was in the hardware reference manual. Comm Spec TP-38 Shared Repeater Tone Panel The TP-38 tone panel is a cost effective replacement for community repeater tone panels which are used to decode several different tones on a repeater system. Different groups of users sharing the repeater are each assigned their own tone frequency so that they don't need to listen to other users of the repeater who are not part of their group. In the application shown here, the TP-38 is used as a general purpose sub- audible tone decoder, connecting to the repeater receiver and providing a PL logic signal to the controller. The TP-38 decodes any or all of the 38 standard sub-audible tone frequencies. With its DTMF option, each tone may be enabled or disabled independently, remotely, using Touch-Tone commands (independent of the RC-850 command set). The unit can also cross code, or generate a different tone output in response to a particular received tone. Use of the TP-38 can provide the system owner the ultimate in flexibility in sub-audible tone operation. Program the hang time in the TP-38 to zero and connect it to the RC-850 controller as shown below. The TP-38's "PTT" output becomes the PL signal to the RC-850 controller. tom -Original Message- >From: wd8chl >Sent: Feb 12, 2009 2:47 PM >To: Repeater-Builder@yahoogroups.com >Subject: Re: [Repeater-Builder] Re: Anyone ever interface a CSI TP3200 tone >panel to an external controller? > >All you have to do is, like you thought, program the 3200 for no hang >time and blank the ID's.
