Radio Amateurs

[Wirezfree]

Hi,

Yes, the RTL SDR(USB Stick) is very popular.
SDR Radio's are definitely the future.

I let WSPR run last night on 17M @ 2.0Watts
This morning I was surprised at where my signal was "spotted"
I have a temporary wire antenna @ 8M long at about 5M high.!

@ altman,

Yes, Amateur Radio is alive and kicking...
Not sure which country your in, your flags not showing..??

A guess at some possible country links:

USA: http://www.arrl.org/
UK:  http://rsgb.org/
NZ:  http://www.nzart.org.nz/
AUS: http://www.wia.org.au/

If you are interested you should be able to find info on:

Hey thanx Wirezfree , I m in Canada .

Thanx for the links .

Does someone needs a licence even if done in the internet ! When not in the internet we need one .

I would need a fixed antenna , the one I have is for big trucks that I used to drive .

@ altman,

If you intend to transmit, yes you need to pass various tests/exams.
Not sure how complex they are in Canada..??
Most countries have some form of entry/novice level tests/exams.

There should be info & contact details here: https://www.rac.ca/

I know of this resource Shannon Morse on HAK5 on line at Revision3 webtv . They introduced me to this SDR, TV dongle thing, to get down on HF 600 kc to 30 mc,  There is a kit to build, a x10 divider circuit , like a */10 multiplier circuit same as a mixer that allows the dongle to see below 40 Mhz. There is a full blown TransxCiever kit avail that they explain  "Great Scott Radio kits "  Its meant to be dual band 2meter and uhf hamm band . Its low power like 5 watts , but you can keep building till you got all the power you want.
But I want to look at VHF and up as far as I can for radio testing and repair, Did I mention I have a brain injury and polio, the polio is 60 yrs ago the brain frack is only 5 or so years ago. I have to read every thing very carefully and make notes on papre to do any thing like' sudo apt get -q install xyz' . mostly every cli I ever use is on a tablet in my coat pocket.  and all the new words too ,even old words have new definitions . I can see learning python 3 along with Putty < for my ancient terminal driven test equipment , IFR 2935 and Avcom psa 65c require tty command emulators . like XTERM > is going to be a documented in note book event. I miss having my mind,and short term memory. Backing up in my driveway is a chore I have to look back like 3 times to get it right. 
As far as antennas depends where you are . very simple Jpoles can be made from cable scraps or dipoles. The antenna you had on your truck was prolly for 27 Mhz but it will also work multiples or halves/quarters/eights of 11 meters , up or down it will have sweet spots in it.
Getting this stuff to work on linux is my current problem. I tried to install TOR browser till I gave up. but I did load it on my Dell 810 with no problem.
BTW the 207 H cable was in fact a 208 H cable  but it still works , and I would think opto isolator . with a usb home brew kit. use a RJ45 box to build it in , make newly required adaptor cables  from scarps, as things change I bet they all go to USB or Micro USB any way ..

Hello!

I would need a fixed antenna , the one I have is for big trucks that I used to drive .

Making your own antenna is part of the fun. You can cut the wire antenna to length for the frequency you're using, eliminating the need for an antenna tuner.

QRP radios (<= 5W output) are relatively inexpensive to buy or build, but you WILL need that license. When the conditions are just right, the far-flung areas you can reach with one will surprise you...
