Content preview: Paul John, W1TAG and I found a good way to evaluate software was to run controlled testing between our two stations. The transmit end was configured to easily change power in 1 dB steps so that accurate measurements could be made. We would run the first set of tests during mid day so there was low noise, phase shift and skywave interference. The second test was during nightime conditions ... with all of the above anomolies. We would test for weak signal performance, static immunity and decoder recovery time after loss of signal during the transmission. While we often couldn't put 'precise' numbers on the various modes (especially at night) we could usually resolve things to a couple dB. Comparing one mode against another during these tests definately gave a 'feel' for what modes worked well up to expectation ... and those that didn't.

I think we had a good amount of participation in the test. The only concern I have is that there were very few decodes below -27 or "standard JT9" level. This suggests one of two things. Either 1) There are not many very weak signals arriving at my station or 2) In real world conditions the software is having problems decoding the really weak ones I do not know which it is. The weak ones I did see were early, before QRN built up to overnight levels. Perhaps more testing will result in some better answers. What are others seeing for reported SNR? 2142 -17 0.4 1102 2 CQ NO3M EN91 2154 -17 0.7 1101 2 K5DNL NO3M -25 2158 -14 0.5 1101 2 K5DNL NO3M -25 2224 -23 0.3 1374 2 TST KU4XR 73 2228 -22 0.3 1372 2 TST
