Thanks for all the replies. I'll look into some of the suggestions.

Token, thanks again for a detailed explanation. Your youtube examples are also extremely helpful.  This is one thing I really like about the forums here.  I'm so use to getting short one sentence replies on other forums I visit, this is such a refreshing change.


I have been doing some research into headphones for my iPod, and it seems that the audiophiles think that you should choose headphones based on the type of music you listen to. For example, they say what might sound good for rock music may not sound good with classical.

Do you who use headphones have a set dedicated to this type of listening or can you recommend what you are using?  For this type of listening, would cheap computer gaming headphones work as well as more expensive music headphones?

In this context, what is a sounder?

Sorry to hear that you couldn't get it working on the iMac.  Is that a new pc or borrowed?

... When I was a member( I apparently was booted for lack of posts just the other day)...

I guess I'm not the only one who was booted for lack of inactivity. ;)  It's a good group with lots of information. They just don't tolerate lurkers or semi-active members. 

SDR - Software Defined Radio / Re: HDSDR on Mac OS X
« on: April 05, 2013, 0253 UTC »
The OS X port found here  http://subdimensions.com/2013/03/25/hdsdr-osx-2-60-port/ seems like it will work, but since I only have an RTL dongle I haven't been able to get it to recognize the dongle.  From the "CAT EXTIO Config ENG" file:
Choose your radio
1. Put the folder "HDSDR OSX" on your desktop
2. Go to http://sourceforge.net/apps/mediawiki/hamlib/index.php?title=Supported_Radios
3. Find the manufacturer of your radio and click on models
4. Find the model of your radio and take note of the "Rig#"
5. Right click on "HDSDR OSX" and chose "Show package contents"
6. Double click on "drive_c", "Program Files", "HDSDR"
7. Open with TextEdit "ExtIO_HamLib.cfg"
8. Find "# Rig Number" text
9. On the next row delete "1" and insert your "Rig#"
10. Save
11. Run the application "Terminal" located in "Applications", "Utility"
12. Type: ls /dev/tty.* and press enter
13. Identify the USB to RS232 conversione interface e.g. "/dev/tty.usbserial"

Setup serial port - Method A
1. Copy and paste in terminal: cd ~/"desktop/hdsdr osx/hdsdr osx.app/contents/resources/dosdevices" then press enter
2. Type: ln -s YOUR-USB-RS232-DEVICE com1 e.g. "ln /dev/tty.usbserial com1"

I can't find a rig number for an rtlsdr.

The HDSDR - Hardware page http://www.hdsdr.de/hardware.html lists a .dll file for RTLSDR (DVB-T/DAB with RTL2832) which I downloaded and replaced the the ExtIO_HamLib.cfg file with that one. Still no luck.

When showing the package contents of HDSR OSX I noticed that the ExtIO_HamLib.cfg located in 'drive_C/Program Files/HDSDR/' is Highlighted in red. I assume this indicated some error in the file but I'm not sure what it is.

Also, running "ls /dev/tty.*" in terminal only brings up "/dev/tty.Bluetooth-Modem and /dev/tty.Bluetooth-PDA-Sync.

Thanks Chris.

This website has a link to a HDSDR 2.60 OS X port.  http://subdimensions.com/2013/03/25/hdsdr-osx-2-60-port/  The page is in Italian, but Google Chrome will translate.  Here is a video of it running supossedly with an Afedri SDR-Net. http://www.youtube.com/watch?v=cEow-0iz5N0 No audio that I could get.

I've downloaded the file and will try it tonight with my rtl-dongle.

So you can't change the IP address in that Network Setup screen?

Steve,  Try changing the 0 (zero) in the SDR IP address to 1 and see what happens.
What is your internet service provider, cable, telephone, other?

So no luck with SdrDx?  I agree with Chris and I think you would have to change all of the 192.168 addresses to match. It sounds like the sdr has a static ip. is there a way to change it to use dynamic ip's? I'm guessing that is what your computer is doing if you have it connected to a router. In my experience, most home routers are set to default using dynamic ip addressing (DHCP).

Hi Steve,

Thanks for the link. We are in the middle of job hunting so the wife isn't real keen on the idea of putting an antenna outside if we end up having to move. Anything should be better than what I have now, a Grundig G3 Traveler with the telescopic antenna. I also have a Kaito KA33 active loop, but I haven't noticed any improvement.

I recently purchased one direct from NooElec. I received notice that it shipped today. Now I need to get an antenna! No chance right now to put one outside, so I'm thinking about something in the attic (a dipole or loop). If worse comes to worse, I may have to string some wire around the room where the computer is.

Hey gang.  My Afedri is in NYC, I'll let you know how it goes as soon as I get it.   K5kNT, I'm running an 07 imac, 2 ghz processor with 2 ghz of ram.  I just updated to osx 10.6.8 and have sdr dx loaded up and ready to go.  Since I'm not very tech savy, I plan to run the afedri into the ethernet connection so that I dont have to mess with networking software and I can take advantage of the higher bandwidth.

I dont have windows on my mac, so Im hoping for plug and play.  One can dream, right? LOL.



Thanks for the update.  I'm hoping for plug and play also  ;D
