Thanks for sharing Tom.<br>
<br>
I gave a listen for a short period. A lot of the traffic was rather
difficult for me to understand. There were times I could tell what
was being said, other times not so. Probably about 50/50.<br>
<br>
Our system is currently still patching digital over to an analog
channel, so it's a mix of both depending on the user. For some
reason the digital traffic is a lot easier to understand. 90% of
the time it is copyable. The remaining 10% is lost to the technology
and I can't pull it out with my ears. The stuff still analog is,
well, absolutely great.<br>
<br>
The Uniden scanner I had for a short while (programmed it for a
friend) was pretty dismal on digital.<br>

Yes. Have a listen yourself:<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
<a class="moz-txt-link-freetext" href="https://smile.amazon.com/gp/product/B01HA642SW/">https://smile.amazon.com/gp/product/B01HA642SW/</a><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>
