<p class="MsoNormal">Wouxon HTs seem to do that even on systems with perfectly good squelch. Maybe they slowly reduce the transmit power or something. It seems worse when you're close to the receiver. <o:p></o:p></p>

<p class="MsoNormal">As far as your usbradio long squelch tail problem; some radios just don't have enough high frequency noise to drive the DSP properly. In that case you have to use simpleUSB.<o:p></o:p></p>

<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Also please note that even with a properly working DSP squelch quickly kerchunking will produce a long squelch tail... just like MICOR squelch will do. <o:p></o:p></p>

is 776 and SQ setting is 900. This does eliminate the SQ tail but I’m sure this is going to affect RX sensitivity over all being so high. There appears to be a very narrow range of SQ levels that provide no SQ tail and decode is fair. Most problematic are
the Wouxon radios.</span><span style="font-size:11.0pt;font-family:"Calibri","sans-serif""><o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif"">I had to go back to my URI interface and my FT-736R. I have it set up to do tone encode and decode using the URI. All the encode and decode are working however when I unkey
there is a squelch tail that lasts about 1 to 2 seconds. I’m allowing the URI to determine COR thru DSP. The connections are setup for raw audio both ways with the node supplying the pre and de emphasis. I have played with the settings but nothing changes
the problem. It isn’t a consistent duration of tail. I know it is in tone decode mode because if I turn tone off on the portable I can’t open the squelch thru the node. Anyone have any ideas……<o:p></o:p></span></p>
