Good afternoon, Several of us playing with ISCAT on 6m have noticed that it has a difficult time decoding the RRR message regardless of signal strength. This is occurring both with the standard RRR message in WSJT 10 and with alternate messages in an experimental version of WSJT we are using. Typical non decode is as follows, note the consistency
180545 4 -3 3.1 -43 0 * ND0B W5LDA -6 14 10 10 2.2 180615 3 -2 11.5 -43 0 * ND0B W5LDA RRT 15 5 10 1.1 180645 6 -2 12.6 -43 0 * ND0B W5LDA RRT 15 5 10 2.2 180715 3 -2 11.5 -43 0 * ND0B W5LDA RRT 15 5 10 1.1 180745 2 -5 2.6 -43 0 * ND0B W5LDA RRR 15 6 10 2.2 180815 6 -2 14.3 -43 0 * ND0B W5LDA RRT 15 5 10 2.2 180845 2 -3 4.2 -43 0 * ND0B W5LDA 73 14 10 10 1.1 As an experiment we put spaces between the Rs, this decoded every time 181045 8 -2 9.8 -43 5 * ND0B W5LDA R R R 17 5 10 4.5 181115 8 -2 9.3 -43 5 * ND0B W5LDA R R R 17 5 10 4.5 181145 8 -2 11.5 -43 5 * ND0B W5LDA R R R 17 4 10 4.5 As a further experiment we changed it to SSS... again decoded every time 182115 3 -2 9.8 -43 0 * ND0B W5LDA SSS 15 9 10 1.1 182130 0 -20 0.0 0 0 0 0 0 0.0 182145 3 -2 2.0 -43 0 * ND0B W5LDA SSS 15 10 10 1.1 182200 0 -20 0.0 0 0 0 0 0 0.0 182215 3 -2 1.5 -43 0 * ND0B W5LDA SSS 15 10 10 1.1 Any thoughts on where I might start looking for this issue would be greatly appreciated. This is happening on 10.0 5490 release as well as the experimental version I developed. It also happens with just the RRR message. Thank you! 73 de Bill ND0B
