cesco, How is what we tested somehow flawed in your mind? Lets keep a positive outlook on those few (very, very few) hams who are willing to give some reports on their experiences with these new modes and even how they compare. I wish we had time for additional comparisons to some of the

How is what we tested somehow flawed in your mind? Compare it to testing psk31 against jt65 at snr's of -20db. psk31 wont work, jt65 will work. Flawed test. Your report of easypal only getting 1/6 of transmission is a clear indication that conditions or setup were not adequate. I could not

Cesco, This is ridiculous. In no way did we trash your free mode! And please be aware that RFSM2400 is the same price as EasyPal ... free in terms of monetary cost. If you look at the results dispassionately, you will see that the SSTV mode did quite well considering it must have been on the

Unluckily i have to say that this comparison is quite flawed... using easypal which needs minimum 6db SNR in the lowest setting in conditions of less than 4db snr (1/6 throghput you say) is not a good idea. Comparing that to a mode which can adapt to lower snr's is BS at best. Your invited to

I'm not sure what Les wrote about the cost of the product, but my understanding was that there was a temporary $60 price associated with RFSM8000 from the normal price. The question is: who will buy it at any price? If you have seen what has happened to other developers who tried to charge

It is ironic you should mention the P38, Les. Quite some years ago I was one of the early adopters of new technology. Not usually the bleeding edge, but close to it. Tried a number of boxes, including the Kantronics UTU, plug in card for Pactor for the C-64 computer, AEA CP-1 with BMK Multi

I noticed that there are images that are sent with an RS 1 through 4 and then I think it converts them to jpg? The RSx files are additionally encoded. I dont remember the exact numbers but i think it allows 10% errors on rs1, 50% errors on rs4. You can actually decode an rs4 file when 50%

When I first started poking around, I found a simple comparison paper at http://ieeexplore.ieee.org/iel2/672/6329/00247152.pdf . It appears to require an IEEE membership, or a university internet connection(I'm VPNed into my uni right now). The bottom of each page does say U. S. Government

Sorry about the line breaks...note to self, don't trust the post preview function. What I forgot to mention here is that when the adaptive equalizer models the channel, we can use that information for more than just equalizing the channel. Most current ARQ modes make a decision if the
