Re: [wsjt-devel] SuperFox can have split misconfigured and make fewer QSOs (setXIT anomaly?)

2024-10-07 Thread Matt Power via wsjt-devel
One way to address the single issue of a SuperFox with mismatched Tx and Rx dial frequencies is this small change to setXIT. My understanding is that, in the SuperFox case, setXIT still must actively set the Tx frequency, because it may often be misconfigured if (for example) normal FT8 had been us

[wsjt-devel] SuperFox can have split misconfigured and make fewer QSOs (setXIT anomaly?)

2024-10-05 Thread Matt Power via wsjt-devel
Here's apparently a bug in both WSJT-X 2.7.0-rc7 and WSJT-X v2.7.1-devel 241005-RC7 (aka yesterday's wsjt-x_improved). The essence is that a SuperFox transmitting station can sometimes accidentally be misconfigured with their radio's dial frequency different on transmit and receive (e.g., transmit

> Be sure to setup a contest-specific CQ message, e.g., CQ FTRU If you transmit CQ FTRU instead of CQ RU, then the number of stations decoding your CQ will (on average) be fewer. The a1 AP decoding for FT4 and FT8 depends on the standard CQ message format for the selected contest setting. For exa

Re: [wsjt-devel] use of NTP with WSJT-X disrupted by Windows 10 updates

2018-12-04 Thread Matt Power
Yes, possibly it would help if individual users choose an OS other than Windows 10 Home. This doesn't solve the general problem. The presence of any users with misconfigured time synchronization hurts everyone because it reduces the probability that an arbitrary QSO attempt will be completed effici

[wsjt-devel] use of NTP with WSJT-X disrupted by Windows 10 updates

2018-12-03 Thread Matt Power
WSJT-X on Windows has generally expected that the machine has third-party NTP software and doesn't use the Windows Time service. This affects clock accuracy, and consequently affects decoding performance in various ways, including the possibility of being affected by the recently identified "negati

hint65.f90 currently has "MAXMSG=2*MAXCALLS + 2 + MAXRPT" and generates thousands of hypothetical messages of the form: msg=mycall//' '//call2(i)//' '//grid2(i) msg='CQ '//call2(i)//' '//grid2(i) These aren't as helpful when chasing an EME DXpedition. Is there interest in an increase to "MAXM

[wsjt-devel] rc1 to rc2 upgrade can disrupt decoding if UseRef is set

2017-09-03 Thread Matt Power
I had an issue where, after upgrading from 1.8.0-rc1 to 1.8.0-rc2, no receiver output was shown in the Wide Graph and no signals (e.g., FT8 or JT65) were decoded. It turned out that WSJT-X.ini had a UseRef=true line in the [WideGraph] section. Changing it to false fixed the issue. For me, this is
