We have evaluated the following modes for terrestrial work: Ranked from worst to best decode performance, at lowest possible tx power. Q65-15A : RC3 has worked much better than earlier releases. Surprisingly effective. We had no problem finishing a qso every morning we attempted one, and ran for 30 minutes to verify band conditions. Q65-30A : Clearly superior to 15A Q65-30B : Better than 30A, but not night and day. Q65-120E: Dramatically better on terrestrial paths than all others tested, including 120A, but hard on equipment (transmit heating) Overall 30A is an excellent choice. Random CQ's on 50.275 do work, but nothing like FT8, of course. We are seeing (or were) increasing activity on 275 30A. ....until FT8 started opening to DX on 6m. Everyone disappeared (and rightly so...I worked 67 European stations one day and 8 JA's on another) :-) Operator density is the key to enjoying random qsos. ======================================================== Further testing with K5GZR 864 miles: Q65 30A RC3 M2 6M5X @ 25' with 100' of Davis Bury Flex : N0AN 70 w (he has high noise) 131900 -8 0.2 2008 : N0AN K5GZR EL29 q3 100 watts out 132000 -16 0.2 2008 : N0AN K5GZR EL29 q3 132100 -8 0.2 2008 : N0AN K5GZR EL29 q3 132200 -6 0.2 2008 : N0AN K5GZR R-20 q3 132300 -14 0.2 2008 : N0AN K5GZR R-20 q3 132400 -19 0.2 2008 : N0AN K5GZR R-20 q3 Now 25 watts out 132600 -25 0.2 2008 : N0AN K5GZR R-20 q32 132800 -28 0.2 2001 : N0AN K5GZR R-20 q3 133000 -9 0.2 2008 : N0AN K5GZR R-20 q3 Now 15 watts out 133500 -32 0.1 2005 : N0AN K5GZR R-20 q35 133800 -19 0.2 2002 : N0AN K5GZR R-20 q3 133900 -11 0.2 2002 : N0AN K5GZR R-20 q3 134000 -19 0.2 2002 : N0AN K5GZR R-20 q3 134100 -12 0.2 2002 : N0AN K5GZR R-20 q3 134300 -23 0.2 1999 : N0AN K5GZR R-20 q32 134400 -20 0.1 2002 : N0AN K5GZR R-20 q3 134600 -3 0.2 2002 : N0AN K5GZR R-20 q3 134700 -17 0.1 2002 : N0AN K5GZR R-20 q3 134800 -7 0.2 2002 : N0AN K5GZR R-20 q3 Power Returned to 100 watts out 134900 -7 0.2 2002 : N0AN K5GZR R-20 q3 135000 -13 0.2 2002 : N0AN K5GZR R-20 q3 *Link to *.jpg of Testing Group and Wattmeter showing Power Output at KB7IJ* https://drive.google.com/file/d/1NUgAR3vZRAfzD8Z-JXVZ9a-afRGQPHBi/view?usp=sharing Thanks to all the following for the extensive tests: KB7IJ, Rich K5GZR, Rick (Geezer) ND0B, Bill WB4HIE, James NM3G, Rick The results reported here have been consistent with all our prior testing (hundreds of hours over several months), with perhaps one discernable change: Q65-15A works much better now than in the early versions. We have no idea why. Summary: *When a contact absolutely must be made, Q65 is the mode to use*. It makes use of every propagation mode that may be present, and is perhaps unique in this respect. Q65 makes use of : Ionoscatter Troposcatter Meteor scatter Tropospheric Ducting Sporadic E F2 Airplane Scatter Ground Wave EME Line-of-Sight The propagation mode doesn't seem to matter. *If there is a signal present, no matter what propagation mode exists at that instant, Q65 will take advantage of it. * (*Do NOT take this out of context, it is not a replacement for MSK144 when there is a plethora of meteors available*) We have observed 2 or 3 propagation modes being used at the same time, based on the signature of the signals on an SDR graph, showing amplitude vs. time, over repeated rx sequences. Each propagation mode, looks different on the signal history graph. Classic trapezoid for some meteor scatter, random low level peaks for Ionoscatter, etc., etc. Pros and Cons vs. Other Modes: 1. Q65 does not appear to be well suited to a busy passband with overlapping signals, which FT8 excels at. Q65 sensitivity is superior to FT8, FT4, MSK144 etc. 2. FT8, while permitting a highly shared passband, does not handle strong signal excursions well at all. (meteor pings destroy an FT8 decode) 3. The way MSK144 is currently used, (Time Division Multiplexing), the frequency cannot be shared (as a passband). If someone is in local or Es is in, MSK144 requires a QSY or changing sequences. 4. Q65-30A, for example, is about 200 Hz wide, so if the available passband is 300 to 2800 Hz, quite a few qsos can take place that do not overlap. Some overlap appears to be tolerated, but not a lot and not with large signal differences. *No mode, not even Q65, can work when none of the above propagation modes exist. It may appear to be magical, but it's not. :-)* Our experience indicates that with patience and persistence, Q65 in its various configurations will outperform nearly all the other WSJT-X modes on 6 meters and requires very modest station setups to successfully complete digital contacts of extraordinary distance at very low power levels. *The typical 100w output setup with a small yagi, can easily complete 1000+ miles contacts every morning, if one's local noise is not excessive.* 73, N0AN Hasan On Mon, Jul 5, 2021 at 8:02 AM Joe Taylor <[email protected]> wrote: > > Dear WSJT-X and MAP65 Users, > > We are pleased to announce that a public Release Candidate WSJT-X > 2.5.0-rc3 is ready for download by beta testers.
