If you're getting a +5 SNR report then obviously dial it way back but when I do DX at 100 Watts it's usually -10 or less. Here is what FT8 signals looks like, displayed in the WSJT-X waterfall view: Youll see from the above waterfall screenshot that there are over a dozen QSOs visible these are all taking place on a single frequency of 14.074MHz. With the bonus of DAX not requiring A/D conversion and the attendant degradation of received signals, your great installation, radio, and location really do put you ahead of the average Joe. It's in fact often practically unattended. On the other hand, the almost complete automation of the process definitely reduces the role of operator skills. Please review the new, If you are having a problem, please refer to the. The data being gathered also includes more than just PSK spots, it include JT65 and FT8 -- with FT8 the overwhelming majority at the moment. First off, you need to connect your PC to your HF rig. It's not a measure of your output. The exchange above would therefore take about 90 seconds (compared with seven minutes on JT65). I've seen the same, that outlier station with a good receive setup or just weird propagation magic that copies you +12 while everyone else in that grid is coping you -10. On average I run about 30 watts only on this mode and have had some success on 70cms along with the other bands. The bandwidth is 50Hz. If theres any interest, Im happy to expend this article, but hopefully this tells you what FT8 is all about, and gives you enough to get started. Forgot your password?

I think this violates the Terms of Service. Nothing defaults to paragraph. The full coax length of LMR400 is about 160 feet long (to the tower and up). I've seen variations of that kind coming from the same. MOD input should only listen to you PC of course. From my playing I think this one is alc related. When the conventional FT8 sub-band on 6, 20, 30, or 40m seems too full, please try moving your dial frequency down 3 kHz! The chart above shows the agreed-on frequencies for FT8. The tone is only used for CW (Continuous Wave aka Morse Code) transmissions. It's only used to exchange signal reports, so there's no chatting. Is there a setting that I am missing somewhere to fix this problem. I feed the IQ output of my 7610 into HDSDR and then feed the audio out of HDSDR into WSJT-X through a virtual audio feed. Welcome to Reddit's own amateur (ham) radio club. Typically the interface will appear as a COM port and WSJTX will need to be set to the correct COM, PTT So that the PC can put the rig into Transmit, the software needs to know how to trigger Transmit. Here you will see that on my FT8 Transmit some decoded me as +13 and others closer as -3, this can be due to skip zones as well as different antenna setups, etc. Lots of variables here. By . The numbers tell you the strength of your FSK signal (6.25 Hz) as it compares to the signals in an entire 2.5 kHz SSB bandwidth.
