HamSphere

[5B4AIT]

Hello I am Kelly, 5B4AIT from Cyprus.

HamSphere is software Tranceiver that works in Windows, Linux or Mac or any other Java driven system. It communicates over a simulated Ionosphere called "HamSphere". It covers 6m to 160m bands.

HamSphere uses real radio principles with local oscillators, balanced mixers, filters etc. The modulation is true Double Sideband Modulation with carrier suppression hence the "donald duck" sound when you swirl the knob. The receiver is a direct LO-mixer detector where we just add the carrier (Beat oscillator) to detect the audio. Filters are made from 17-pole FIR filters producing effective 3.8, 2.8 and 0.7 kHz filters.

The unique feature of HamSphere is that the user can maintain connections under natural realistic conditions. Signals may vary and interference is present giving the user the impression that he or she is using a real shortwave transceiver.

Greetings from the other end of the island!

I wonder if SSTV (etc) will work on hamsphere? I suppose it will if the "band noise" isn't too strong!

Wonderful software to simulate HAM RADIO...........This virtual radio sounds like & feels like the real thing............Many users from worldwide have been registered and new ones signing-up every day great to see the activity !! For those that can not have HAM RADIO antenna due to many different reasons this is the answer to continue DXing , rag-chewing and just plain simulating the hobby over the internet voip programs............... Wonderful ......... vic

Oh yes, in version 3.0 you will be able to use full 4 kHz bandwidth just like in HamSphere 1.0. There will be a switch between using codecs and not. Have in mind that without codec, the bit speed will be 128kBits/s.

Also I have dedicated the 30 meter band to digital and SSTV traffic only and the noise level will be lowered.

There are a lot of new features in 3.0 and I have recently presented a list of new features. http://www.hamsphere.com/read.php?4,3156

Not my cup of tea I'm afraid - I have radio for that kind of thing. For VOIP to my family etc I use Skype.

With the simulated propagation etc you've made a good job of it but I clicked on the DXCluster link and it shows really weird callsigns, nothing like real life at all. It could be interesting as a training aid but I'd find that very distracting.

umm - I can't login right now, still, it looks like an exellent training tool...
