Firmware Update RH536 and VLC over WiFi issues
It all works pretty good together and I really enjoy being able to be located far away from the receiver where it gets the best reception in my house and still be able to listen and pretty much control the radio. Thanks Uniden, looking forward to future upgrades for the BCD536HP.
So far I've noticed 2 issues with this setup that I haven't seen mentioned so I thought I'd bring it to everyone's attention to see if it is just my setup or if others have noticed them as well.
First I noticed that on all Conventional Systems that utilize CTCSS sub tones that I was getting a low level hum in the audio when the CTCSS sub audio was indicated in RH536. I suppose I was hearing this because I'm feeding the audio through my 5.1 surround sound card with a large subwoofer. Apparently the sub audio tones are not being filtered before the audio digitization from the BCD536HP. As the sub audio frequencies changed on the display from 88Hz - 150Hz you could hear the corresponding differences in frequency. In VLC I set the 60Hz and 170Hz equalizer sliders to minimum (Tools->Effects and Filters) and this cured the problem. It also had the advantage of eliminating some of the P25 "bassy" distortion that others have complained about.
Second I have experienced very infrequent loss of connection back to the BCD536HP. I could ping back to the BCD536HP but I could not re-start either VLC or RH536. I used Zenmap (a part of Nmap) to port scan the BCD536HP and compared the result to when it was running properly and noticed that the normally open tcp ports 80 and 554 were no longer visible. I assume that what happened was that the network tcp protocol stack ceased to function in the BCD536HP, the dongle still seemed to be active because of the ping responses so ICMP was still active. This problem has occurred twice after several hours (maybe 6 or more) of continuous use. The BCD536HP was still active and scanning, just no network.
