I have set up an active antenna hooked up to a RTL-SDR. This is babbys first radio hobby stuff i am doing and i wonder how i can "read" morsecode with a program that can translate for me?

eddiewalker posted:FLDIGI is a popular "Swiss army knife" of digital decoding. The interface is a little "open-source" but it's not terrible. i get a local norwegian 159k hertz station so i can hear things. My brother ordered a hamitup box thing. it converts megahertz or something higher. idk i havent read the ARRL Handbook 2013 yet so i dont know much about this (because it is huge and has so much mathematic beautiful mind equations). edit: i got sdr to output to fldigi with some virtual sound cable thing and it works!

After searching for software for sdr i have the following setup: fldigi hdsdr mixW multipsk (lol) sdrconsole 2.3 sdrsharp sigmira sorcerer artemis for sigid I really wish this was more accessible for noobs. I have ordered a telescope mast and i am saving for a discone antenna so i can cover most bands regarding RX. I am also gonna read up and get a radio license (which i was informed is a FULL LICENSE in norway and some other countries have SHAREWARE LICENSES)

I can get an ~70 on practice exams without even looking at any of the test prep so I'll read the study guides a few times and go from there. I am reading up on what i need to know for the norwegian license test (CEPT,SHARE,HAREC equivalent) and there is a lot of math and its dreadful. joule ampere watt coloumbus ohm I Q R blablabla. I dont need to build things from scratch as some kind of irradiated fallout survivor.

Why is it that when i connect a 5 meter metal wire to random places on connectors (sma,usb,BNC(?)) the noise from usb(?) is almost eliminated in 20m ham band????

Do you live in the wilderness? I hate the EMI noise here in the city and i wonder how much improvement one would get in no mans land. Here is my useless royal scanking discone 2000 securely fastened to solid wood mass.  It will go to a lightning surge protector in the white box then to the ventilation to my living room where i have my PC/SDR.

bad news, an 12 mbps isolator wont work with airspy or rtl sdr. I have decided to try out an raspberry pi powered by battery instead. If it still creates noise because hdmi grounds from screen to raspberry then i am going to be intel dead inside.

I got help to put up 20 meter wire from the top of the building to a tree. It was done very goodly and greatly and the coaxial cables now go through the wall into the living room so it looks better than before. If people say that it looks like Africa after all this work then i am going to be annoyed.

My 746 autotuner will actually do the job on all bands but 75, but i dont operate much on that trash band so who cares I havent set up counter poise for my antenna yet so hopefully it will be better at 40, 20 meters.

manero posted:Instead of isolating the USB, maybe isolate the audio ports? You can get cheapo stereo isolators for like $5 on amazon. I use a pair of them taped together for audio stuff with my KX3. Yeah, i tried to make IQ show up in HDSDR but nothing worked until somebody told me the specs of my usb signalink :P The reason i bought usb isolator was for RTL dongle and airspy. But now that i have a stand alone radio unit then i can just isolate audio ports instead.
