Paul, N1BUG, has compiled a short report on a test conducted between Christmas and New Year.
The conclusions are below:
Closing Remarks --------------- On the basis of this test it is evident JT9-5 mode in SlowJT9 decodes at significantly lower signal level than JT9-2 can. Even considering signal fading with the longer transmission periods, JT9-5 gets the message through more often. Additional JT9-5 reports were received from DF6NM, LA3EQ, VE7VV, G0MRF. 2E0ILY reported reception on JT9-5 and JT9-2. KA9CFD reported JT9-5 and JT9-2 with 5 appearing earlier in the evening than 2.
