Amazing and cheap SDR receiver.

For sure. The meter is quite sensitive to change and reads in dB with a typical noise floor of about -82 dB in a quite rural location like mine. You can turn the AGC off as well to get a better reading without AGC action on the meter.

RTL SDR Console

Just a few comments to add to the thread.
There are various SDR programs available but I suggest using SDR CONSOLE V2 (must be V2 as earlier versions do not support RTL dongal). Also SDR Console will, later this year, hopefully integrate with Ham Radio Deluxe. This means that whatever you do on (certain) radios will mimic on SDR Console and visa versa. Why does this matter??? Well obviously ease of use BUT more so I have had chance to compare the $17 Dongal and SDR Console to my IC746 pro. Long story short the $17 dongal beats my $1000 IC746 on RX. If I turn my antenna so my local 6m beacon is just above the noise on my IC746 and then switch the antenna to the input of my SDR I would give the beacon an S3 by ear on the SDR. I have done repeated tests and find all results similar. I have used the SDR to receive both JT65 on HF and FSK meteor scatter on VHF by feeding the audio output of my sdr computer to the audio input of my VHF computer running WJST and JT65-HF.

My next step is to set the system up so that I use a TS440 for TX and my SDR for RX. Once I am happy with this I will make the same mods to my IC746 which I only use for 6/2/222. I think it will make a better RX for MS and EME than my IC746.

I would suggest ordering the HF converter at the same time and from experience DO NOT HOT SWAP the dongal. I blew one up doing that. Not saying it was the hot swap that did it but it never worked again afterwards.
 
Good post and welcome Paul. This is Garth VE1IDX here. I am one of the admins. Thanks for the help the other week in getting SDR Console working. The proper dlls helped. LOL. I have ordered the HF converter and am just waiting for it to arrive.
 
Hi Garth. No problem. I figured I had put in the hours finding all the links and info why should you have to :) I am still amazed at how good these $17 dongals are and wonder just how much better the "good" ones can be. I bought one of these...

To improve the RX but caution you will need good tools and even better eyesight to assemble it. Mine is still in the package as I cannot even see the caps let alone solder them :(

I look forward to reading other peoples results here and again stress go with SDR Console. Simon Brown writes software that I have been impressed with in the past and this too does not disappoint.
 
Thanks again Paul. I remembered seeing a preamp but could not remember where I had seen it. I may order that as well. I plan to take everything and assemble it into a single box allowing full HF thru microwave reception and the preamp all in one tidy housing.
 
I plan on running separate HF and VHF systems but like you will box them all up. I need to find a couple of TMP sockets to make the jumper leads up from inside the rigs to run dual RX. I think once people on here start to play with these they will be impressed. It is nice having the band scope. Once I get my 10 ele 6m Yagi back up I will try the SDR out on EME. Do you run VHF from NS?
 
 
Highland Ranger. Make sure you have a mx (mmxc?) to sma cable and a sma to sma cable along with the standard cell phone charger cable as the HF converter requires the cell phone style cable to power it up.
 
Paul, I am not doing much of anything right now. Last year I replaced my entire antenna and tower system but ran oit of time getting the new antennas on the new tower. Right now all I have is an 80m doublet fed with ladderline thru an auto tuner. This summer will seea pair of stacked 13B2's, homebrew six element 6m yagi, an A3WS for 12/17m and an Explorer 14 for 10/15/20/40m go up on the 64 foot Trylon Titan. Tben I wll be ready for some serious business on 6m with a Larcan amp and a bit of fun on 2m but just with 50 watts for now until I get some more cheap power for that band.

Do not Hot Swap the DONGAL

This is the software you need to download to start with.

Technology previews, just something for the weekend...


Your SDR will not plug and play. Let me know if you are running 32 or 64 bit operating system and I can send you the drivers you need or give you a link to them.


To start with order

Can you post the software and dll files here?

Might be nice to have a separate subsection on SDR stuff. I think were heading towards a world full of this stuff. Very interesting. This is a software developers dream. Low development cost without the hardware costs.
 
#M42Duster I will try to work out how. Just joined this site today so as to help out with SDR questions. So not 100% au fait with the site. If not I will put up a step by step and info on where to find them. First time takes a little bit of working out after that it is OK so that was easy.....
 
SDR installation

Here are the instructions Paul sent earlier. I need to get mine setup and operational...



SDR Install Instructions

Follow these instructions and your R820t dongle will work. Of course the amount of hours I have into it I could have gone and bought a Flex 5000 :)

To use the RTL TV Dongle with Simon Brown's SDR-radio application, you'll need the following two additional components (the following info is certainly readily available, but for a long time, it has been spread all over kingdom come, so absolutely nobody should feel bad for not being able to find it !!):

1) You need a useable USB driver (the one Windows installs automatically is worthless, as you've probably already experienced !!)
- the fastest way to get the required driver is to download the zadig.exe utility from the following URL (note that there is a special version for WinXP - make sure to use the appropriate one)... you'll need 7zip to uncompress the driver archive:
<http://sourceforge.net/projects/libwdi/files/zadig/>

- when you run zadig.exe, if your device does not automatically show up, you can go to the "options" pull-down & select "show all devices"... it will then show up... you want to choose either "Install driver" or "Replace driver" (both are correct)... note also that I experienced where Norton will flag zadig.exe as "suspicious" & it will keep zadig.exe from doing what it needs to... hope you don't have the same !!

2) You need a new DLL file to allow SDR-radio to access the RTL TV Dongle directly via USB (until recently, the only way to do this was to use the DLL or other drivers all supplied by osmocom, but this had legal restrictions, so we previously had to use a very bad work-around called rtl_tcp.exe... luckily this has now been made much simpler!!)

- you can get the required DLL file by going to Simon's V2 preview website at the following URL & scroll down to the section titled "RTL Dlls" where you will find links to the external websites that have agreed to source the compiled DLL for others to use... copy the downloaded files (3 total, pay attention to 32-bit vs. 64-bit versions, depending on your version of Windows) to the same directory where the SDR-radio application is installed:
<http://v2.sdr-radio.com/Configuration/RTLSDRs.aspx>

- now with all of the appropriate drivers installed, run SDR-radio V2

- at the top of the screen, towards the left-hand side, there are 6 icons... click on the blue arrow pointing to the right (that's the start icon)
- when the "Select Radio" dialog opens, click on the "Definitions" button
- when the "Radio Definitions" dialog opens, click on the "Search" button & select "RTL SDR (USB)" from the pull-down list
- you should get a pop-up that indicates "1 entry found - update list?" (assuming you have only a single RTL SDR device installed)
- click the "Yes" button to accept the new entry (clicking Yes if/when you've previously done this detection is OK - in fact, some have reported that they needed to re-detect when moving to a different USB port)
- back at the "Radio Definitions" dialog, click the "OK" button
- back at the "Select Radio" dialog, click on your RTL SDR to highlight it
- if you have more than one VFO enabled/selected, you might also need to click on the "Enable" button (another right-pointing arrow in the specific VFO windows) to start that particular VFO
- if you succeeded, you should be able to click on the "VFO Tuning" button just above the spectrum display to tune to your desired frequency, adjust the mode using the "Freq / Mode / Filter" button in the same area just above the spectrum display
- you might need to click on the spectrum range adjustment button on the right-hand side just above the spectrum scale in order to see anything painted in the spectrum display(s)
- one more thing to note: if you rearrange the display items & get it all scrambled or lose something & can't figure out how to get it back, you can always click on "Display", then "Layout", & finally "Default: Restore" to get everything back in a reasonable state !!

3) Good luck & have fun !!
Let us know when you get it going !!
