Do you mean rxmixerset ? Yes, that helped for me. As to deemphasized audio, this one’s set up for it, all unsquelched and everything. Was set up by W9SH ages ago; I’ve changed software a couple times since. As you say, though, even if the rxnoise automatic adjust didn’t go terribly well, the radios themselves work great, squelch squelches properly, voices don’t get cut off when they shouldn’t, in short, it works great. So I, for one, am definitely a fan of the GM300’s, especially because they can be really easily replaced if something goes wrong. -- Buddy Brannan, KB5ELV - Erie, PA Phone: (814) 860-3194 or 888-75-BUDDY On Oct 5, 2013, at 11:32 AM, George Csahanin <george@dyb.com> wrote:
How about setting the RXGAIN in usbradio.conf? That usually fixes this problem for me.

The 736R seems to be lacking in the HF noise area as I can’t make it to the 27000 number the program is looking for. It almost gets there. About 26231. I’ll have to run a SQ open point test on the radio and see where the SQ opens. I have the test gear to do that. Thanks

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.
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.
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. -- Tim :wq

I have tried tightening the SQ but then I start to have decode issues with some of the connecting radios. The current signal strength reading, no carrier present, 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.

Have you tried increasing the squelch level? What is the current squelch level?

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……
