Re: Multiple Bands on SDR Play

No nvidia card - just the integrated video chip. I opted for a small footprint PC at the beginning of 2015 as in all the years I've had PCs I have only every upped the memory, I have never fitted an expansion card. The PC only has a single expansion slot and if I could squeeze a video card in I'm su...

Re: Multiple Bands on SDR Play

I own a PC with an i5 4460 processor and 8 GB of RAM it cpu benchmark of 6598. With SDR-Console v3 preview I can run five VFO's across an 8 MHz spectrum window - with SDRPlay set to a 10 mbps (10MHz) sample rate. Using the Matrix option I can display all five. In my case I am in the FM broadcast ban...

Re: will upgrade to 12 bit sdrplay help me?

A difficult question to answer - but obviously FM stereo needs a far higher S/N ratio to become noise free. I'm currently listening, on headphones, to BBC R3 classical music in 250 kHz bandwidth. According to SDR# the s/n ratio is 54-55 dB and it is practically noise free. An alternative frequency g...

Re: SDRPlay Performance

Putting some specific numbers to performance. I own a desktop PC running an i5-4460 processor with 8 Gb RAM and Windows 8.1. With SDRPlay at 8MHZ bandwidth when I run in HDSDR it uses around 16% cpu load according to task manager, with a total cpu load of 22-24%. When I run SDRUno or SDR# CPU usage ...

Unable to record or playback

I don't know what I am doing wrong wrong - but when I click on the record button for the first time it comes up with the error message "unable to open output wav file". The rec button lights up - but that is all. When I click on the play arrow I would expect it to open up a file location a...

New API 1.95 improves zero IF image rejection

Having got API 1.95 working by deleting the registry entry as suggested I was then able to check whether there was any improvement in the zero IF image rejection. I'm very pleased to find that there is a significant improvement, so that a signal 60 dB above the noise floor produces only a weak image...

Disaster with API 1.94 (*1.95) and Sharp 1361

I installed API 1.95 and installed the latest ExtIO to HDSDR folder. That is all I dsid - HDSDR works - but I think the decimation is flaky. Then I went back to my tried and tested SDR# build 1361 - and it just sat there not running SDRPlay!!! Just a blank waterfall. So I uninstalled Mirics 1.95 - r...

Re: Odd behaviours spotted so far.

I've noted the same bouncing initially - but now can't reproduce it. When saving a workspace I would really, really, like it to save the size and position of the pop-up windows that I've opened at that point. Then next time I open it everything is where I want it. With a choice of ten workspaces you...

SDR Uno - first impressions

It is going to take a while to get familiar with all the controls but the layout looks good. You can set up the various pop-up windows above the main RX display quite neatly. How to get them to stay there for next time needs investigating. My thoughts for FM-DX use which is 98% of my interest in rec...

How will Studio 1 be made available?

If this or a similar question hasn't already been posted and in the queue - I'll bite the bullet and ask how SDRPlay plan to make Studio 1 available? eg will it be "free" to registered owners? or will it be bundled with new purchases (with a possible change in pricing)? or will it be a cha...
