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
- start to remove many many screws from the bottom of the ft-950
- all screws are off and time to flip cover open!
- there ya go, now to locate scope-plug
- scope-plug located, which states clearly “scope” and is connected to 50ohm dummy. remove the dummy.
- took the dummy off from the plug and taped it in here.
- now spot hole in the left upcorner from where you will insert the tmp->bnc cable.
- mp-adapter looks like this. I had to squeeze it a bit to get it through the rigs back panel ventilation holes.
- 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.
- 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 ! 🙂
