Hi Mal

 

The whole reason these things are getting so much attention is the price and the fact they are independent of a sound card or A/D converter. They are not really suitable for or give any advantage on LF because you need an up converter in front. A Softrock SDR with a good sound card will out perform these sticks at MF/LF.IMHO I don't think its worth persuing to be honest. However I think with the DVB-T sticks people have been opening them up to look at the SMT chip marking if not sure. It looks like they don't erase the markings like some well known LF TX suppiers do. Oh and the software plug-ins are only for the RTL2832 chipset.

ps

My cardbus is a Freecom TV and radio receiver but I cannot find any spec for it  anywhere. Freq range etc

It would be interesting to see how far down it actually went in freq, or even how far up. I could build a suitable up converter to cover LF/MF

I have a DVB-T cardbus and I expect this would also work maybe better than the usb stick. Do not know what the chipset is

Hi all

Save those precious Euros because you don’t know how long they will be around. Try HDSDR with Balint Seeber’s  BorIP app and ExtIO.USRP DLL using  ultra-cheap Software Defined Radio with RTL2832 (chip set) DVB-T USB stick.

These DVB-T USB Digital TV sticks are about £5 to £10 from UK source and cover about 50megs to 1.7gigs and with an up converter 60meg O/T osc the cheap way or expensive Monolithic IC local Oscillator 5v into an SLB-1 or similar block mixer; you too can have a USB (no sound card) SDR RX with DC to UHF coverage for peanuts all run off the USB supply just add antenna.

Oh and guess what the stick gets you all your local digital TV stations with record facility and all your local Digital radio and if that’s not enough all your local FM BC as well.  Not a lot of people know that!

Hi Piotr,

Thanks for the overview of programs. That's what i searched for.
But maybe i have expressed wrongly what i need. I assumed a SDR software is also for a mono input, not only for IQ inputs. Are the programs you're referring on usable for both, IQ and mono?
Well, i'm waiting for one of my SL teachers (Wolf or Markus :-) ) answer. If there is a solution in SpecLab i would prefer that i think...
