I got a couple of useful tips today, played around a little and thought I would pass a long some information to fellow JT65A rookies.
Some of you will have seen the OOO, RO, RRR info pop up on the waterfall, I figured there was a a reason for that. If you line things up with the position on the waterfall, it will aide in decoding and keep the frequency difference to a minimum. Having a wide "DF" is viewed as undesirable and results in the frequency being "hogged". Enter the SPECJT. 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) and Mike VE3FGU added .. "left most green line on the sync tone ".. 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. The band had died here, so will have to do more experimenting with this later today. Andy K3UK Skype Me : callto://andyobrien73 www.obriensweb.com
