Java handles memory usage behind the scenes. The java garbage collector reclaims used memory periodically, but it can get behind if the cpu is being loaded. This can get quite bad if it waits too long and then performs a 'stop-the-world' garbage collect, where you'll see the gui and the whole program lock up, while the garbage collector does its thing. If you see that happening with only 1 channel decoding, please let me know.

I probably need to look at the thread pool again. My dev machine is an i7 with 16GB of RAM running linux. I'll do some testing on some mid-level Windows machines to see if I can get a better balance on CPU usage. During stress testing, I was running 12 channels with 24 decoders, with 12-16% CPU usage and 200 - 600 MB of memory usage.

One thing you can do with the E4000 is to turn down the sample rate when you're only decoding one channel. The 240k and 288k sample rates won't tax your CPU as much.

Hey Denny,
That's definitely what's happening, the "stop the world" garbage collector. The CPU peg was happening during that process, not before. I'm guessing it's using everything it can its hands on, cpu & memory.

I think the fact they're not making the E4000 any more makes them "old" lol.

Hey Denny,

Unfortunately the only USB SDR I own is an R820T, but I'm really looking forward to giving it a try. In fact, I'm so excited to try the Passport and Fleetsync decoding, I might have to buy an E4000 while I wait.

I figured out how to build my own XML file for the systems/sites/channels and got myself up and running.. more observations now

I really like that you 'ghost' other/adjacent channels in the visible part of the spectrum display (as per below). Does anyone know if SDR# has a plugin to emulate this?



How do you come about the PPM correction that shows up as default in the tuner configuration screen? I haven't changed mine because the signal seems to be fairly close, but I'm wondering if it might be the cause of my spotty MDC1200 decode (that's the only signal I have to play with right at this moment).

I also fiddled with the gain settings at one point to try to boost the audio (when I clicked on a signal in the lower left to listen to it, what I heard coming in was fairly quiet and the MDC1200 squawks were not getting captured). Nothing I did seemed to improve the signal, so I set them all back to Auto. Is that the recommended settings?

Oh, and if you don't already have enough on your todo list, DMR/TRBO and NXDN decode (both individual and trunk flavors) would be loved by all I'm sure.

The default PPM settings for the FCD and FCD+ are based on what I used for my dongles. The default for the E4K is Auto.

You can create a custom configuration file for each dongle so that it remembers the last settings you used. If you've set the serial # for each dongle, it associates the configuration with the serial number.

I think the default config setting for the E4K is auto, which doesn't work well at all. I recommend setting it to one of the manual gain settings. I'm traveling at the moment and don't have access to my E4K settings on my home computer, but I think that I'm using something in the 40-ish range.

Added to the list. You can click on the 'Issues' tab on the google project site to see status of suggestions and bug reports and track progress. Folks can submit bug reports there too.

Not sure if you noticed, but you can access the channel context menu by right clicking on each of those ghost panels in the spectral display to enable/disable channel decoder or access the Activity Summary.

I can't right now because I have a lockup of some sort going on. I minimized the program, went into a different full-screen app (a rather graphics-intensive game/simulator, Spin Tires), and when I came back, the waterfall was frozen.

If I hover over a point on the spectral display, I do see the yellow text indicating the frequency, and if it's on a ghosted panel, if I right click and wait, the context menu appears eventually, so the program isn't completely frozen. However, when I go into the lower right panel to try to right-click on the tuner and shut it down, there's a huge amount of lag systemwide, and ultimately, the java app vanishes... but the command prompt window remains open. Here's a copy of the errors thrown there (I captured almost everything from initial launch to the failure - the line ending in "AWT-Windows" is where the GUI window finally disappeared):

I hope you get support added for the R820T tuner as its being sold widely and the E4000 is getting very high in price and its not being made anymore. All I have is 3 NooElec dongles with R820T tuners.

EDIT: oh never mind sheesh just noticed no EDACS and ProVoice decoder in it.

Is it possible that you have another SDR program running that has control of the E4K? On startup, the application attempts to claim the E4K to use it ... something else has control of the E4K and is not allowing SDRTrunk to claim it.

You might try removing the E4K and then plug it back in and restart SDRTrunk. Give the dongle 10 seconds to sync up with the system before you start SDRTrunk.

The 'could not load loading.png' is a bug but shouldn't have any impact.

Hey Denny,

When I posted that bug on the site, I assumed I could make it a low priority, but it wouldn't let me set/change it. I figured it was a good idea just to keep track of it.

Cheers,
N

Hey Denny,

I got past the path variable setup (thanks for walking us through that at the beginning of this thread) but since I only have an RT820 tuner, I tried the mixer/soundcard input with a discriminator tapped scanner... and unfortunately I have thus far been unsuccessful.

I tried every imaginable combination of available Mixer, Channel and volume setting and was unsuccessful at getting anything on several Passport frequencies. I also tried decoding a few Fleetsync bursts with the NBFM decoder (and Fleetsync checked) and was also unsuccessful.

Any idea where I might be going wrong? In the attached photo you can the Passport decoder icon just remained green and said IDLE. The NBFM decoder was also green in an idle state, and all other decoders (LTR, LTR-Net and MPT1327) were red. There was also no activity on the spectral or waterfall displays, but I wasn't sure if that was normal since no SDR tuner was being used.

Thanks for your help!

I don't have a discriminator tapped scanner to use in testing. I ran a few tests against LTR-Net discriminator audio recordings provided by a local user and the LTR decoder doesn't work at all. The LTR decoder is used for LTR, LTR-Net and Passport. I'll do some experimenting and see if I can get it to work with the discriminator tapped audio.

With Fleetsync, MDC1200 and MPT1327, you can use standard headset audio output from your scanner to feed the computer sound card input. These signal types use signalling at 1200 and 1800 hertz, which is right in the middle of the audio passband, so you don't need the discriminator tap. Setup the decoder the same way you would if you were using an SDR dongle ( NBFM + Fleetsync, or NBFM + MDC, or MPT-1327 ).

Each of the decoders detect input data type, either from a sound card input or an SDR dongle. When it's from an SDR Dongle, an FM demodulator is included in the decoder chain. When it's from a sound card, the data is assumed to already be demodulated.

I think I'm going to add a setting to hide the spectrum/waterfall when you're not using an SDR dongle, so that you're not staring at a blank display.

I'll have the R820T support finished shortly. CAP has completely tapped my free time for the past few weeks, but that's starting to ease up.

Denny

It looks like you've got it configured correctly to decode passport. What are you feeding into your line-in audio input?

Passport channels broadcast an idle message every 1-2 seconds, so if you're guess is correct, you'll see decoded IDLE messages, all with the same site number, in the Messages tab.
