JT9-5 vs JT9-10 Test 12-15 January 2019 TX Station: N1BUG Location: FN55mf Power: 1W EIRP Frequency: 136 kHz TX Format: JT9-10, then JT9-5, repeat cycle every 20 minutes JT9-5 Message: VVV N1BUG 5 JT9-10 Message: VVV N1BUG X Introductory Remarks -------------------- SlowJT9 is an application being developed by Rik, ON7YD / OR7T. It aims to bring back the long abandoned slow JT9 modes which were once included in WSJT-X. The slower modes may be used to good advantage for weak signal QSOs on LF and MF. The goal of this test was to see whether JT9-10 decodes in situations were JT9-5 cannot. A beacon alternating one JT-10 transmission immediately followed by one JT9-5 transmission, this pattern repeating every ten minutes, was operated for three nights. Reception reports received are included in this report. Reports which included only one mode are not included, but were greatly appreciated. There were reports from stations who were both listening and transmitting which are not included here. The work load of trying to subtract periods when they were transmitting in order to not skew the data is prohibitive.

SlowJT9 decodes at lower signal level than JT9-5 can. Confidence in this test is lower than for previous runs. Many receiving stations had software configuration issues. Nevertheless there is clear evidence JT9-10 decodes more times in a given night than JT9-5 when signals are weak. Additional reports for single modes were received from several stations. In addtion, several stations sent reports which could not be reasonably processed (eg. stations which were also transmitting). All reports are appreciated. This experiment ended ubruptly at dawn on January 16 due to fire in the antenna loading coil! END OF REPORT
