Multiple SDR# Instances

[Slick36]

Just an FYI:

When I try to run two instances of SDR#, one using SDRPlay and the other an RTL dongle, my entire Windows 8.1 desktop crashes with what used to be a BSOD. This is the first time this has happened since I upgraded to Windows 8 when it first came out.

The event viewer says:

The computer has rebooted from a bugcheck. The bugcheck was: 0x0000009f (0x0000000000000003, 0xffffe00043ac32a0, 0xfffff800afeb3aa0, 0xffffe000478e4640). A dump was saved in: C:\WINDOWS\MEMORY.DMP. Report Id: 062815-8406-01.

I would be happy to send the memory dump on request.

This has nothing to do with sdrplay but more the usb controller that you have, the above link is maybe a hint to solve it.

Are you running from separate folders for each instance or are you trying to run from the same folder??

It might re-assure you to know that I am running the same set up as you are trying to achieve i.e. Windows 8.1, one instance of SDR# with an RTL-SDR dongle and one instance of SDR# running the SDRPlay. Each SDR# instance is in its own folder and for test purposes I actually have a total of four instances of SDR# installed. The computer has an 15-4460 processor and 8Gb of memory. SDR# plug0ins installed for each are RDSDatalogger, MPXOutput, FM Suite (beta), TV

Thanks all for your replies.

I have three 'Standard Enhanced PCI to USB Controller' entries in my device manager. Could these be what you're looking for? The Microsoft support page says it's for Vista/7, I'm running 8.1. When I run the fix from Microsoft, it says it doesn't apply to my version.

I run the two instances from the same folder. Should I run each instance from it's own install folder?

BTW, other than this minor problem, SDRPlay is VASTLY superior to any other dongle! Every household should have one.

Hey Slick36,

yes each instance of SDR# needs to be run from seperate folders, so get a good working one set up, then duplicate the folder and make changes as you need them, I have one for my SDRPlay, one for RTL, one for RTL with Upconverter, but sadly, since getting the SDRPlay, the RTL's find very little use these days

I have SDRPlay and 2 x R820T2 dongles - bought after the SDR Play. I use one RTL dongle permanently connected to my older laptop and my 5 ele FM yagi pointing south. Running RDSDatalogger with SDR# it moniotrs the bottom hlf of the band for SpE. Not as good as the SDRPlay of course but when I'm concentrating on Italian/South-East/East Europe it gives a good number of Spanish/Potuguese/Moroccan stations. The other dongle is linked to the north-east aerial and picked up a couple of nice openings to the Baltic/Scandanavia when the main system was pointing elsewhere. It's also very good for the 66-74 MHZ FM band from Eastern Europe and Band I TV DX.

I may upgrade to another SDR Play or a FunCube Pro+ for background scanning.
