Hopefully you will here from a local ham. If you do not, I may be able to help, I have some experience in setting up a digikeyey with the Icom 7000 and Icom 746 Pro, I helped a ham in my area get all set for digimodes . I would recommend that you start with the DX Lab suite of applications. I

Hello Tony, Would it be possible for me to run the SDR feature without actually having and SDR rig attached? If so, how can I activate it? The SDR feature in Multipsk is only doing a I/Q processing, shifting in base band, in USB or LSB, a selected band (inside the 48, 96 or 192 KHz SdR band).

[digitalradio] Performance of modes: weak signal and poor ionospheric conditions

2010-01-31 Thread Wes Cosand
I have finished a series of simulations looking at the performance of several modes that seemed appropriate for extended keyboard to keyboard rag chew QSOs.  I was looking at modes that offered a throughput of about 40 wpm so they could keep up with a reasonable typist with a bandwidth of no more

MFSK16 always seems to come up near or at the top of the simulated tests but I can't duplicate that in the real world. My experience is that Olivia 8/500 does as well if not better and gives MUCH greater latitude in tuning while still providing 100% copy under moderate to poor conditions.

Andy, Patrick is way ahead of all of us. I forgot to mention that when I first installed the E2180 dual core cpu/motherboard it only had 500GB of memory. The digital mode and SDR applications actually ran OK and the cpu usage was quite low but the memory shortage was very obvious when

Ed: With 500 GB of memory you should have no trouble running any program likely to be produced in the next few years. MixW can get a pretty good range of resolution. In the case of resolution, looking at 20 m on MixW at a zoom factor of 0.5, the spread on the display is 14.070 through
