New OSX and Windows version of SdrDx – 2.08

SdrDx 2.08 supercedes the UDP interface in 2.07 (UDP still present in case you’ve coded for it) with a TCP server interface that is capable of supporting multiple clients. It turns out there’s a rather serious bug in OSX that prevents UDP connections from being opened with more than one client, so TCP is better for now.

As with the UDP interface, I’ve included a basic TCP client example written in Python.

In addition, beginning with SdrDx 2.08, the program will let you know if and when upgrades are available to you in the program’s title bar, as long as you have an Internet connection when you start it.

The TCP interface now has many additional commands as compared to the previous version’s UDP command set, and so far we’ve got an alpha version of an iPad client that displays waterfall, spectrum, demod envelope, allows tuning and other control, and plays back audio — all using the new TCP interface. In addition, during the beta period, tuning control for a screwdriver antenna was implemented using the TCP interface and Python.

I have a multi-VFO (26 of them, A-Z) application I’ve made available (OSX only so far) that works with the new TCP interface as well, giving you copious radio-like VFO control over SdrDx. Each VFO remembers frequency and all related display settings, so you can frequency hop like a little radio bunny. (cough) Sorry. :)

SdrDx 2.08 provides for frequency offset, which in turn allows it to be used more easily with up-converters such as those that might be part of a FUNcube installation.

There are various other changes, mostly small tweaks and bugfixes. Enjoy!

RFSPACE SDR-IQ and Mac OSX 10.5.8 Leopard

No Mac support as yet, but… install VMWARE and XP, and it works great. I’m listening to Radio Havana on 6050 KHz right now on a three foot piece of wire. Tomorrow, when I can buy a length of coax, I’ll hook it up to my shortwave antenna, which is out of reach of my computer desktop right now. I expect to have a lot of fun.

I tried it with Parallels 2, but Parallels screws up the USB connection and it just won’t fly. It was less expensive to “cross-grade” to VMWARE than it was to buy a Parallels “support incident”, so Parallels just lost a paying customer. Funny how that works. VMWARE imported my Parallels XP VM without comment, and the only catch was that XP bitched at me about having to be re-registered because “my hardware had changed significantly.” Oops. Turns out that wasn’t a problem… re-registration went smoothly, just a couple clicks and it was done. One of the benefits of having a legal copy, I presume.

Anyway, just thought it’d be worth noting for Mac users that you too can have an SDR instrument on your desktop. You do have to run it inside a Windows VM, but that doesn’t seem to be much of an inconvenience.

On the left, you see WinRadio; it has a lot fewer features than SpectraVue, but on the other hand, it acts a good deal more like a radio than a spectrum analysis tool. It doesn’t seem to have any system for managing memories, but that may just be new-user unfamiliarity. I confess to not (yet) having RTFM. I will update this post if I learn otherwise.

Some benefits WinRadio brings to the desktop are ECSS reception for standard SW and AM signals, and DRM (Digital Radio Mondial), a digital reception mode. ECSS works very well indeed; DRM is… well, it’s interesting. Haven’t got that figured out yet. I downloaded the DReaM decoder, and tuned in to some DRM broadcasts, but haven’t got anything to report other than no success.
