ft-950 and 32usd band-scope project – see what you hear

 First.. thanks for this site (and various of others) to give me idea to start playing with cheap bandscope project with rtlsdr-stick (dvb-t)


I have been playing with rtlsdr for quite long, and after aquiring a Yaesu FT-950 I was ofcourse going through what I can do with the rig and accessories.  Then after some lucky google search I came to tarapippo’s site and got the idea to test bandscope myself.

Here is what you need in general:

rtlsdr compliant dvb-t stick 10 euro  in ebay like here : http://www.ebay.co.uk/itm/390613356279?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

bnc to mcx adapter 9 euro in ebay like here: http://www.ebay.co.uk/itm/230961193408?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

tmp to bnc adapter 5 euro +shipping from funk amateur: http://www.box73.de/product_info.php?products_id=1990




  1. start to remove many many screws from the bottom of the ft-950
  2. all screws are off and time to flip cover open!
  3. there ya go, now to locate scope-plug
  4. scope-plug located, which states clearly “scope” and is connected to 50ohm dummy. remove the dummy.
  5. took the dummy off from the plug and taped it in here.
  6. now spot hole in the left upcorner from where you will insert the tmp->bnc cable.
  7. mp-adapter looks like this. I had to squeeze it a bit to get it through the rigs back panel ventilation holes.
  8. then comes the “hard” part. push tmp cable toward the hole in left up corner and use pliers to pick it up from the hole.
  9. then connect it to the scope-plug and youre done! 🙂


After that you can connect the bnc-adapter to bnc-mcx and mcx to dvb-t stick and to your computer.  

Then you can startup your favourite SDR-software, tune to 69MHz and start catching signals on HF. Some SDR software (like HDSDR)

supports also CAT-controlling.  There is 3 images in the bottom of this blog, and listed in order 15m/digi ,  20m/ssb, 40m/ssb.   73 de OH2FXD ! 🙂
