Re: Windows driver installation

Some additions: I let the SDRPlay run with SDRConsole, and there is no error up to now (4h run time). So, it could be that something in the extio.dll could cause the failure since the new driver is in the game on both setups. I'll let it run the rest of the night, let's see if it runs stable.

Re: Windows driver installation

Hm ... I thought I was done, but I'm not. On my desktop PC (Intel I3 on ASUS MB, just a standard PC) it happens after app. one or two hours that the running SDRPlay stops working. I've seen it in SDRSharp and HDSDR. The windows sound for unplugging a HW component appears and then the fft display fre...

Re: Windows driver installation

Hi all, thank you very much for your support! I finally got it solved by opening device manger, go to the unknown device (which was the Mirics), update driver and select driver from directory (not automatically select driver!). Then I selected the Mirics TV driver in its directory and it did the ins...

Re: Windows driver installation

Hi, I do not belong to the lucky part of users ... I cannot get it installed on my HP7 Stream running Win10. I removed the AVAST security package, I removed the old (faulty) driver installation - but the new driver is not installed correctly. The Mirics driver install exe runs without any message, b...

Re: SDRPlay and Linx 8 tablet

Hi, unfortunately I cannot get it installed on my HP 7 Stream. The AVAST does always prevent the installation of the Mirics driver. I tried to disable it, I told the scanner that it shall not check these files, but that does not work, Deep Screen guard is going to check the driver install exe but ne...

Re: Bandfilter

Hi, I did it: I inserted a new bandpass filter into the SDRPlay and bypassed the existing one. It is a band pass filter 3rd order (47pF+220nH in series, 220pF||68nH to GND, and again 47pF+220nH in series). You can calculate it by yourself: http://www.electronicdeveloper.de/FilterPassivBandpassLCT_Vo...

Re: Bandfilter

Hello,

thank you very much for your explanations, that clears up what happens.
So, the best solution will be to have another band pass filter with better stop band attenuation below 30MHz. Maybe just an additional 30MHz high pass filter will be enough. Let's heat up the soldering iron ...

Re: Bandfilter

Hello, I did a quick test with the new API & DLL, maybe that helps. LO @ 50MHz, 8MHz sample width Switching from auto to 144MHz band plan eliminates most of the ghost signals. (waterfall: upper part 144MHz, lower part auto band plan) Auto-to-144MHz LO Plan.jpg Switching from 144MHz to 168MHz band pl...

Bandfilter

Hi, I have the SDRPlay since a few weeks now and I must say it has a good performance for the money it costs. Especially shortwave works fine. However, beside the driver install problem with Win10 resp. tablet computers I'm not very satisfied with the band filter performance in the VHF range. Have a...
