Hi Philip One possibility is multiple decodes from extra strong signal and likely an overdriven transmitter. That +13 next to a -15 is a good indicator that the -15 is a splatter kind of signal. I have seen some with 3 or 4 decodes, all within a few hundred hertz.
I also get it when I have multiple laptops on the same radio line out cable or multiple WSJT-X instances running on the same computer. The monitor-only instances decoded during the transmit period and are reporting out. In my case it was +18 though usually without sidebands here. After seeing this I now turn off PSK reporter in the monitor instances, as well as in JTAlert for those instances. If you search for K7MDL spots in the last week I have been experimenting using my sub receiver with a 2nd instance of WSJT-X and JTAlert. You will likely find some odd 6M spots matching my transmissions on the low bands. Additionally, since the 2nd and 3rd+ instances are not connected to the radio, they do not change band info, so more than once I had the wrong band reported for the spots it did make. Now I try to make it a routing to disable spotting for non-rig connected instances. * Mike K7MDL From: Philip Gladstone <[email protected]> Sent: Sunday, January 20, 2019 22:34 To: [email protected] Subject: [wsjt-devel] Puzzling behaviour in packets sent to pskreporter I notice that I am getting a bunch of duplicates in the packets (as seen in the raw packet captures) being sent to pskreporter. For example: WE6Z reported seeing KG7VOR twice at Jan 21, 2019 03:03:29. The only differences were: One entry had Frequency 1841279 with snr -15 Another had Frequency 1841400 with snr of 13 In fact there were 9 spots of KG7VOR in the same packet (at five difference timestamps). This is not limited to a few cases, but it appears a fair amount. At the same time, I'm getting comments from people that not all of their spots are being reported -- so I'm wondering if this duplication is actually a symptom of something more serious....
