[arm-allstar] simpleusb flash tone nominal level

[Patrick Perdue]

Everything was far too quiet at 500 for rx and tx. The flash test tone 
was only hitting the meter at around -22Db. So, I turned on a 20DB boost 
on the HRI-200, which decreased the signal to noise ratio but gave a 
better reading. I then turned that 20DB boost off and compensated by 
putting the TX level from Simpleusb at 894. Yes, precisely 894, which is 
what gives me exactly -6DB with the test tone on the HRI-200's input. I 
just want to know what that tone's nominal value is without any sort of 
attenuation or boost, so I know what to look for on the other side.

I'm trying to avoid using things like simpleusb RX Boost and the 
HRI-200's 20DB gain for sake of keeping the noise floor as low as 
possible while providing as much amplitude as is feasible in both 
directions.

And, to be fair, a noise floor of -55DB vs. -66DB doesn't really matter 
so much when you're listening on an analog radio, but this goes out to 
several other modes as well. This is part of a multi-mode system 
involving, at this point, 7 different modes. Optimizing audio quality 
between all modes has been a challenge, but an interesting one.

> Patrick,I would go with defaults in simpleusbtune. Rx and Tx levels set to 500. In wires-x under audio adjustments test tone should be set to 6 green bars on output Tx. Using the loopback you want 8 to 9 green bars on input.If you can not adjust properly, you may need to readjust Rx and Tx in simpleusbtune.David KG5RDF

Thus, as far as HamVoIP is concerned, the HRI-200 is a radio. As far as the HRI-200 is concerned, the URI is a radio. So, HamVoIP talks to the HRI-200, which gets me to the wires x network through the wires x software.I didn't design the cable that goes between the URI and the HRI-200.As the HRI-200 shows up as an audio device on the Windows machine, I just opened up a DAW, selected the HRI-200's input and got readings from the peak meter as it was sent the test tone.In short, the URI is just a substitution for an analog radio or repeater as far as the HRI-200 goes. There is no actual RF involved.On 7/10/2020 10:26 AM, "kg5rdf via ARM-allstar" wrote:> Patrick,Can you explain what the HRI-200 rf interface is connected to (URI?) and if it is connected to the server in Japan.

I have no other Yaesu equipment, so I can't monitor what comes out of my Allstar node into the HRI-200.I can, however, read meters on the host machine.Currently, I have everything calibrated such that the test tone hits the input of the HRI-200 at just a little above -6DB. I know that tone is pretty hot, but I don't know what value I should aim for to get as close to a 1:1 ratio as possible, perhaps with a little headroom. Should I be using something closer to -6, or 0 as a reference?Thanks and 73deKE4DYI_______________________________________________ARM-allstar mailing listARM-allstar at hamvoip.orghttp://lists .hamvoip.org/cgi-bin/mailman/listinfo/arm-allstarVisit the BBB and RPi2/3/4 web page - http://hamvoip.org> _______________________________________________>> ARM-allstar mailing list> ARM-allstar at hamvoip.org> http://lists.hamvoip.org/cgi-bin/mailman/listinfo/arm-allstar>> Visit the BBB and RPi2/3/4 web page - http://hamvoip.org_______________________________________________ARM-allstar mailing listARM-allstar at hamvoip.orghttp://lists.hamvoip.org/cgi-bin/mailman/listinfo/arm-allstarVisit the BBB and RPi2/3/4 web page - http://hamvoip.org
