ProScan: Proscan Choppy Audio at Client using Remote Scanner Over IP

[MarkyM]

Hi,

I'm trying to setup Remote Scanner Over IP in Proscan. Just over my local network for now, but am getting audio dropouts on the client side.

The scanner is a Uniden SDS100 and the server side PC is a Windows 11 laptop on Wi-Fi.
Using the Loopback function in Proscan, the audio is stable with no dropouts on the server side as heard through the laptop speakers.

But at the client side, a Windows 11 desktop on wired Ethernet, the audio drops out for about 5 seconds after every 10 seconds of clear audio. This cycle repeats over and over...10 seconds good followed by 5 seconds bad etc. I have tried different sample and bit rates with no difference.

The router is a TP Link 7200 and the Wi-Fi signal is strong at the client side. In fact I'm testing now near the desktop which is close to the router.

I have forwarded the port I'm using through the router and through the eset software firewall on both machines.
Connection to the server on the client is quick and no errors are shown. Remote control of the scanner works fine.

Any suggestions on what to try next to get rid of these dropouts?

Update: I left it up for a while this morning and the client disconnected after about 5 minutes:



Thanks!

While I contend that connecting your server via WiFi should work fine (I do it with many different servers) IF the WiFi is properly configured and not dropping out for power management / usb factors... have you tried connecting the server directly to your network with an Ethernet cable? If you do that and the Proscan audio / connection streaming issue goes away... then you know it is something to do with your WiFi ... or the available CPU load / horsepower... and not Proscan.

Thanks for the reply.

Unfortunately, this laptop does not have a wired Ethernet port. It is just 2 years old and as laptops get thinner, they are removing those ports.
I don't blame Proscan. I know it's a laptop or network problem. And I apologize for asking for some buffering. Proscan is fine and I in no way regret purchasing it.

I'm just going to give up on this project for now. The goal was to have it upstairs connected to an antenna and be able to monitor in the basement as I work. This is really not imperative. I'll enjoy my SDS100 in person for now

Just a thought, probably a dumb one but here goes...

I didn't see you mention, have you trying the web server option? Does the audio have problems there?

If the web server acts as expected you can monitor and control from that.

I'm not smart enough to know if just because one way doesn't work that means the other way won't work either.

Good luck figuring this out.

As I posted listen to the Video the OP posted everytime they receive an email the audio cuts out.

Have you tried listening with just the ProScan Client software, and not the full Proscan program in client mode?

Yes, the client app has the same dropouts.

The Web Server is playing without dropouts in Firefox. Sounds great!
And entering a password and then logging in as Super User, I have full control!
Thank you!!

Dropouts listening to just your server or others online?

I only get the dropouts when using my server via "Remote Scanner Over IP". Other servers online play fine.
But now, using the "Web Server" function instead, I have no dropouts and full control when logged in as Super User.
The difference seems to be that there is a second or so of buffering delay on the Web Server. But that's fine for my use.

This is also working in the Safari browser on my iPad.

Is the 192.168.68.60:27457 you inside ip address or is that your outside ip address?

192.168.x..x is usually the routers inside address, I could never get RSOIP to work with that range. But then I think I never tried port forwarding the inside address.

Inside.

You might try it with the outside address of the computer hooked to the scanner as one would normally setup ProScan RSOIP and see if that clears up the audio.

I may try that at some point. Thanks.

have you tried an isolation transformer between the SDS100 Handheld and Computer running Proscan?
Adjusting audio from an Earphone port and Microphone port is a very tricky thing. I love using the LAN option on my 536's and SDS200's
but also use the Record out to LINE IN on my 996p2's 15's and 15x's.

Amazon.com

I'm using a Movo Line to Mic level attenuator cable from the headphone jack of the SDS100 to the Mic input of a little Sabrent USB dongle into the laptop.

The attenuator cable knocked out most of the noise but there was still some there.
So I ordered that Ground Loop Noise Isolator. It came today and knocked out the rest of the noise. Thanks!

I've been a happy Proscan user for many years. Ever since switching to a 996P2 my audio has been a bit crappy. Noise and popping. I never scoped it but it sounds like there's some DC on the signal. It finally ticked me off enough this week that I purchased the isolator you linked to. Wow, I should have done that a year ago. Huge difference! Thanks for posting that link, I had been too lazy to really look for one.
