<div dir="ltr">One thing that I liked about using the dsp for squelch and ctcss detect was what I like to call "time travel" in that the first syllable spoken even before the ctcss is detected, doesn't get lost. I now use the voter boards/RTCMs and that is hardware ctcss and squelch and now everyone using the repeater has to remember to delay talking or the first syllable and sometimes word will not be heard. but everything else about the voter board/RTCM is great and I wouldn't go back. But maybe a future 2nd or 3rd generation voterboard will have a powerful enough CPU that it can also do DSP squelch and ctcss, or at least have enough RAM that it can always be storing audio even when no ctcss is detected so that it too can do the "time travel" thing and never miss any audio while waiting to detect ctcss. <div>
Before the voter boards/RTCMs, all I used was usbradio and DSP, and it worked great and sounded great.<div>Chuck WB9UUS</div><div> </div></div></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Sat, Nov 2, 2013 at 11:57 PM, Johnny Keeker <span dir="ltr"><<a href="mailto:cypresstower@yahoo.com" target="_blank">cypresstower@yahoo.com</a>></span> wrote:<br>

<div>you all are getting too far into the weeds...it ain't broadcast audio, though it can sound better than most repeaters on the air today. 9600 is fine; the levels you'll get are more than sufficient to work with. don't forget to put it into data mode and lock it. add in the rx boost, and you'll have more than you need to do whatever you want. let asterisk dsp if you have the cpu chops do what it does. push composite back in, set your levels, and enjoy.<br clear="none">

<br clear="none">The <span>Alinco</span> has both flat and <span>pre</span>/<span>de</span>-emphasized audio available on its data connector as 1200 baud and 9600 baud connections.<br clear="none"><br clear="none">I assume I would use the 1200 baud connections along with COS and <span>PTT</span> for a simple <span>USB</span> interface and the 9600 baud connections along with just the <span>PTT</span> for a <span>DSP</span> interface?<br clear="none">
<br clear="none">Do I use the (<span>Alinco</span> 9600 baud) audio to the TX also? Does the <span>DSP</span> <span>pre</span>-emphasize audio or is the processing just on the receive side?<br clear="none"><br clear="none">
Why would I want to use one over the other (<span>DSP</span> vs simple <span>USB</span>)? Which is preferred and/or works better? I am thinking there might be some differing opinions here!<br clear="none"><br clear="none">
The <span>DMK</span> URI has both mic_DC and mic_AC
inputs. Does this refer to frequency response or just that one has DC blocking?<br clear="none"><br clear="none">If you are using flat response (<span>DSP</span>) would the audio in (from the receiver) connections at the URI end matter?<br clear="none">
<br clear="none">The <span>DMK</span> URI has both COS and <span>CTSS</span> inputs. Why would you use one over the other?
