<br>
Yes. Have a listen yourself:<br>
http://allstar.kd7lxl.hamwan.net:8000/<br>
<br>
It's monitoring two talkgroups, so if it seems like it's cutting<br>
between two conversations that is why. Compared to my Uniden scanner<br>
there is a lot lower latency at the beginning of each transmission<br>
(the Uniden will miss the beginning of the transmission).<br>
<br>
Hardware is<br>
- 1090 MHz ADS-B antenna at about 20 ft.<br>
- SMA tee (other side goes to the ADS-B receiver). This messes up the<br>
impedance, but not really a big deal for receive.<br>
- NooElec RTL-SDR with TCXO https://smile.amazon.com/gp/product/B01HA642SW/<br>
- Intel NUC DN2820FYKH with Intel Celeron N2820 (I know I said I<br>
started with a VM, but I transitioned to the Nuc for permanent<br>
installation.)<br>
<br>
Biggest outstanding issue I want to correct is audio level<br>
equalization / compression. The dispatch consoles seem to a lot hotter<br>
than most of the subscriber radios. I have not been able to get LADSPA<br>
dysonCompress to work.<br>
