Hi Graham
 
Yep it's Ham Radio Graham, but not as we know it.
 
BTW, Do you get the feeling there's an echo somewhere on this reflector??

Well   unintended   consequence   may  be playing  a  part  in this  as well , by the  time the  project  was  finished ,I think   it  was  out of  economic  production  range   , the  rest  is on-going history  as  development costs  probably  will  not  be  re-claimed , its  cheap  , but  not  that  cheap  ,  same as  lots  of  posts  about  making   digital  back-ends  for  older  HF  radios  ...eh !   , £10  soft rock  or  a  dongel  , job  done , something  in qst / qex  looks  10  years too  late  , why not a  Leakey  grid  6c4  AM detector , if  you  want to  go  retro
 
24  bit  compared to the  8 bit  USB-TV   , but  apparently  that's  not the  problem that  might  be  imagined ......Ive one  sitting  in the  box ,  still  slowly  working down the  things to  do  list ......... now  one that   Tx over that  range  . that  would be  handy !

Hi Marco
 
Beware vested interests we are talking cheap here, Funcube is not cheap!!!!!! This whole exercise exposes the dark side of ham radio publishing. I could say more but suffice to say the DVB-T stick is probably a lower spec than that. But not at a ratio of 10 to 1!!!

Hello Pete,
I bought a Funcube Dongle (covers 60-1700MHz) 2 weeks ago and it’s very impressive how this small USB stick works.
I compared on 4m (70MHz) the Funcube with my converter and could receive with the Funcube dongle many stations via Sporadic E nearly with the same signal strength.
SDR program is SDR-Radio http://sdr-radio.com/

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!
URLs apply………
You won’t read about this in Radcom……. :0)

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...

Best 73, Stefan/DK7FC
