Well, all I can say is THANKS!, Andrew. Your little blurb about that Sync Tone did the trick..... I was clueless about the real relationship between SpecJT and WSJT displays.
I was on 7076 when a signal came up. I just clicked on what appeared to be the Sync Tone in WSJT and Voila! The "slider" on SpecJT suddenly moved to the signal I was seeing and topped astride it. Up until then I wasn't printing anything - after the slider moved, I printed a CQ and tried my hand at connecting with the station as shown below - it worked: 022700 4 -3 0.2 -196 3 * CQ W6SZ DM14 1 0 022800 1 -30 0.1 40 5 * 022900 6 -4 0.2 -196 3 * CQ W6SZ DM14 1 0 023100 7 -5 0.3 -196 3 * CQ W6SZ DM14 1 0 023300 5 -4 0.2 -196 3 * CQ W6SZ DM14 1 0 023500 6 -4 -0.9 -196 3 # W6IDS W6SZ DM14 OOO 1 0 023700 10 -5 -0.8 -196 3 # W6IDS W6SZ DM14 OOO 1 0 023900 9 -5 -0.8 -196 3 # W6IDS W6SZ DM14 OOO 1 0 024100 10 -16 -196 4 RO ? 024300 10 -18 -196 4 RRR ? 024500 10 -8 -196 4 73 ? 024600 5 -28 42 2 73 ? 024700 9 -3 -0.8 -196 3 * TNX 1 0 Now, I have to admit I wasn't watching to see if everything lined up in WSJT as you described.....I was too excited. All I did was click on that large pulse. After that contact, I found I was printing a whole bunch more than in previous days of testing: 024900 6 -4 -0.8 0 3 * CQ W6SZ DM14 1 0 025000 2 -14 -0.5 24 3 * HB9TLK K3UK FN02 1 0 025100 7 -2 -0.9 0 3 * CQ W6SZ DM14 1 0 025200 10 -18 24 4 RO ? 025300 10 -14 -475 3 RRR ? 025400 10 -20 25 5 RRR ? 025500 10 -10 -475 2 RRR ? 025600 10 -19 25 0 73 ? 025700 10 -7 -475 4 73 ? 025800 0 -31 -1.5 -498 7 025900 4 -8 -1.9 -474 4 * K3UK HB9TLK JN47 1 0 030000 0 -33 10.0 -388 41 030100 5 -13 -1.9 -474 4 * K3UK HB9TLK JN47 1 0 030200 0 -32 4.0 -719 2 030300 9 -12 -1.9 -474 4 * CQ HB9TLK JN47 1 0 Anyway, I broke the ice tonight. Still a bunch to put together but at least I accomplished something. That was neat! When making a contact, are we supposed to manually engage each of the TX1 - TX6 message keys in the proper sequence, or does it all happen "automagically" with the "AUTO is ON" engaged? I turned the AUTO to off during the exchanges because I noticed that I was going into transmit mode before the DECODING was done and I could see his transmission.

I had no clue about this display other than it looked cool. By it's self it appeared to do nothing. However if you have SPECJT and the WJST waterfall on the screen at the same time, you will notice SPECT responds to clicks on the WJTS mains screen waterfall. I am told that a good precise frequency can be achieved by sync'ing with the tones. "the sync tone would be at 0, and the three red lines will be in the RO/RRR/73 positions...easy to decode even if timing off. The lowest tone is always the sync tone, even when sending the SH messages (WD4KPD David) >SNIP< >SNIP< So, it seems that our goal should be to find the sync tone, align it with the left most green line by clicking on in in the JT65A waterfall and getting the RO/OOO stuff within the three RED lines on SPECJT.
