Subject: [wsjt-devel] WSJT-X 2.0.0: GA release

The WSJT Development Group is pleased to announce the general
availability (GA) release of WSJT-X Version 2.0.0.

If you have been using version 1.9.1 or earlier, or one of the candidate
releases v2.0.0-rc#, it's important to upgrade now.? The original
protocols for FT8 and MSK144 are no longer supported.? With v1.9.1 and
earlier you cannot communicate with WSJT-X 2.0 using these modes.

We now recommend using WSJT-X 2.0 anywhere in the conventional FT8 and
MSK144 sub-bands.? Everyone should upgrade to v2.0 by no later than
January 1, 2019.

NEW FEATURES IN WSJT-X 2.0
--------------------------

1. Compound and nonstandard callsigns are automatically recognized and
handled using new FT8 and MSK144 message formats.

2. The new FT8 protocol provides optimized message formats for North
American VHF contests, European VHF contests, ARRL Field Day, and ARRL
RTTY Roundup.? Similarly, the new MSK144 protocol provides optimized
message formats for North American VHF and European VHF contests.? Full
support is provided for "/R" and "/P" calls in the relevant contests.

3. The new protocols provide nearly equal (or better) sensitivity
compared to the old ones, and lower false decode rates.

4. New logging features are provided for contesting and for "Fox"
(DXpedition) mode.? Logging is optionally integrated with N1MM Logger+
and WriteLog.

5. Color highlighting of decoded messages provides worked-before status
for callsigns, grid locators, DXCC entities, continents, CQ Zones, and
ITU zones on a “by band” and “by mode” basis, and for stations that have
uploaded their logs to Logbook of the World (LoTW) within a specified
time interval.

6. The WSPR decoder now achieves decodes down to S/N = -31 dB.? For the
particular benefit of LF/MF users, an option "No own call decodes" has
been added.

7. The UDP messages sent to companion programs have been expanded and
improved.

A more detailed list of program changes can be found in the cumulative
Release Notes:


Upgrading from earlier versions of WSJT-X should be seamless.? There is
no need to uninstall a previous version or move any files.

Please do not continue to use any release candidate -- that is, any beta
release with "-rc#" in the version name.

Links to installation packages for Windows, Linux, and Macintosh are
available here:


You can also download the packages from our SourceForge site:

It may take a short time for the SourceForge site to be updated.

We hope you will enjoy using WSJT-X Version 2.0.0.

Question?

Does the current uBITX production version include the spur? and harmonic improvement mods that have been discussed on this group? (ie new relays, etc)
If not,? when can one expect changes to be made to be made on present production.?

I'm Going to buy a ubitx, but wanted to wait unit purity issues are solved.?

Thanks in advance for info

Hi Ripley,

? Thank you for the clarification!? My intent was to relate to Jerry that the bidirectional RF amps were still stock.? The amp immediately prior to the filter (that used to feed the mixer directly) has a trio of SMD 2N3904s marked Q20, Q21, and Q22 on the V3 schematic.? I didn't see that you'd replaced those with BFR106s yet, though might have missed plenty.? OM Farhan recommended changing R26 and R46 on the stock amps to help reduce distortion - something else for you to test.? hi hi??

? Is your signal in spec now except for 10 m SSB?

? ?Thanks again for? your work!

Hi Andy,

A slight clarification, actually I replaced Q92, Q93, Q96, Q97 with 2N2222A and the emitter resistors along with Q90 and the change of resistors per Allison’s recommendation First. Then checked for effect in evening out the power across the bands. Then I did the 45MHz crystal filter second. Once again checking the before and after results followed by the relay replacement of KT1-KT3. As with the other mods checking the before and after to see if it improved the performance.

?

I haven’t been able to spend much time on the uBITX lately but the next thing that I want to try is replacing L5 and L7 with surface mount inductors per the experiment that Raj tried but I am also going to keep 45MHz crystal filter in circuit. I want to see if those two mods together will reduce those pesky spurs on 10 meter SSB further.

A number of people are working to meet different thresholds of 'take care'-edness (two more times in print and it's a real word).? A few (probably in a nod to the phase noise wars) are pushing for a standard just shy of unobtanium.? Others are working to meet regulatory requirements.? Ripley, KD8UYQ, found that relays and a 45 MHz crystal/transformer/cap was quite effective.? That's on a board using the stock 3904s for Q20/Q21/Q22 and before Farhan's recent emitter current increase for Q21/Q22.


Thanks for pointing out Farhan's recent post about current production boards.? That's a curious statement and one that reverses two previous posts that make clear that the relays had been updated and that fixes are added to production on the fly.? I guess I'll "have" to order another one after the holidays and see what's different.

Interesting on needing to match the 45 MHz filters.? After enjoying the process of matching crystals for my in-progress scratch build, it might be interesting to check the 45 MHz filters I purchased from AliExpress and Mini-Kits.? If I recall, the point of the 2nd filter is to remove the "stuff not 45 MHz".? That might mean that a wider variant of the filter would be useful/usable there and might not need to be a narrow filter closely matched to Y1.? TIme to fire-up the Sweeperino, maybe.? Since matched pairs are available, though...

I don't see a post yet that clearly spells out how to take care of the spurs.
This should include pointers to specific parts, show how they get mounted to the board,
include fixes for both the 45mhz-DialFreq and the 12mhz spurs.
And not be spread across dozens of different posts over the past couple months.

Any chance the the QRP Guys would like to put together a bag of parts in the BOM and sell them separately to be added on to the order of a JackAl board?

the Atmel AVR chip can be clocked up to 20MHz, with that said what frequency would be best if we were to replace the crystal on the Arduino board to shift that birdiey to another less offensive location.?
