Good information. Is there a way to verify this?

Here are the subands from the ARRL International Digital Contest:

FT4 and FT8 recommended subbands (as of June 2022)-



FT-4 Recommended Sub-bands

(Technician licensees are limited (per FCC Rules) to using only the
10 and 6 meter subbands {see below in bold}):

1.836-1.840 (users are encouraged to avoiding WSPR operations on 1.840)
3.580-3.590
7.080-7.090
14.080-14.090
21.080-21.090
28.080-28.090
50.330 to 50.340

When choosing your operating frequency, set the radio dial at the
bottom of the sub-band and QSO with stations on audio frequencies
within the radio passband, typically 2.5-4 kHz wide. If a sub-band
becomes crowded, move the radio dial frequency up in 2 kHz
increments, as needed. (For example: 7.080, 7.082, 7.084, 7.086 and
7.088) >


FT-8 Recommended Sub-bands

(Technician licensees are limited (per FCC Rules) to using only the
10 and 6 meter subbands {see below in bold}):

1.840-1.844 (users are encouraged to avoiding WSPR operations on 1.840)
3.590-3.600 (No Digital above 3600)
7.090-7.100
14.090-14.100
21.090-21.100
28.090-28.100
50.340 to 50.350

When choosing your operating frequency, set the radio dial at the
bottom of the sub-band and QSO with stations on audio frequencies
within the radio passband typically 2.5-4 kHz wide. If a sub-band
becomes crowded, move the radio dial frequency up in 2 kHz
increments, as needed. (For example: 7,090, 7.092, 7.094, 7.096 and
7.098)

Note: These "recommended frequencies" will conflict with any traditional
RTTY Field Day activity

1) When in Contest mode calling CQ especially in FT4/SO2R, there is not enough time to reset the TX Enable button. Is there a way this could be changed to allow a "pending enable TX" so you could reset for the next cycle before the previous QSO is finished?
2) Related to #1, would like an optional hot key to reset TX Enable.
3) I havent tried 2.6 yet, but would like to be able to switch in and out of Contest mode with a button. Does this work the same as the Hound on/off?

Wondering what FT4 & FT8 frequencies are likely to be the hot spots during this weekends Field Day?

73, Dick- K9OM

Does anyone have the steps for installing WSJT-X 2.5.0 on Windows 11? My rig is an FTDX10. What additional drivers do I need since I can't find USB AUDIO CODEC? Also, how do I select a virtual COM port in WSJT-X > Settings > Audio?

Thanks. I am a long time WSJT-X user on a Mac M1 and Windows 10. Windows 11 is a whole different beast.

I wonder whether it would be helpful if instead of remaining on the normal FT8 frequency for the band currently in use, selecting 'Hound' mode changed the Hound frequency to whatever seems to be most commonly used on that band for F/H operations.

It really Fox that defines the frequency and wsjt-x informs Fox operator:
---------------------------
Please choose another dial frequency. WSJT-X will not operate in Fox mode in the standard FT8 sub-bands.
---------------------------
So using WSJT-X there is no Fox using standard frequencies. A Hound transmission as such on any frequency is just waste of resources as no Fox will answer. There is no "standard" DXpedition frequencies, so Hound operator needs to set the proper frequency in any case.

Those transmission using Fox kind multifrequency transmissions are using a derivate program. If I have informed correctly even that program recommends other than standard sub-bands. So it is a failure of the operator, isn't it.

73, Reino OH3mA

I Hope someone can help. When I am in a QSO on fT8 everything works fine until the last transmission from me. It does not transmit through the full transmission cycle. The transmission goes on and then immediately off. Sometimes, I get through to the other person and many times I don't. So, if I transmit my 73, there is a quick on transmit and then off---less than a second. The same happens if my last transmission is the RR.

Any help?

Thanks,

Even that protocol should not be used on standard frequencies.<

I wonder whether it would be helpful if instead of remaining on the normal FT8 frequency for the band currently in use, selecting 'Hound' mode changed the Hound frequency to whatever seems to be most commonly used on that band for F/H operations. For example, pressing 'H' always changed from 14074 to 14090, or 21074 to 21091. It might also reset the cursor to a default frequency somewhere above 1000Hz.

Of course these F/H frequencies aren't set in stone but causing the software to change them might help remind the user to change mental mode to Hound operation.

Dennis,
You can set up WSJT-X for field day operation.

On the WSJT-X main window...
Select FILE, then SETTINGS
Go to the "Advanced tab"...
Select the check box for "Special Operating Activity"
Select "ARRL Field Day"
In the "FD Exch: box enter your exchange: ie 1D SNJ (station class and ARRL section)

You're all set.

My recommendations are as follows:
1. I don’t use automatic logging. I found it missed some QSOs, and didn’t
provide enough operator feedback to ensure all the QSOs were logged.
2. That means the Log Prompt Window will pop up for every QSO, which is
fine. When it pops up, always click on “OK” if you want to log the QSO.
Don’t use the ENTER key.
3. There is an option on one of the setup screens to clear the DXCall and
grid box when you log the QSO. I would check that box.

Sequence would then be:
Rx an RR73
Log Prompt Window opens
Click on OK if you want to log QSO
DXCall box should be empty when Q is logged

Have fun at FD! I’m traveling, so this will be the first FD I’ve missed in
many a year.

I think auto logging it has been changed to be contest mode allowed
only......(see under reporting tab)

Guys forgive me if my question is a combination of programs ! I use wsjtx with JT Alert and N3FJP for logging and everything is automated. I make the contact and it logs !!! I am going to operate my (first) Field Day on WSJTX, using our club call sign and have no clue on how to do a proper operation. It is my understanding I have to manually log every contact and the automated process will not work. I would just like to ask if someone has operated FD and give me your suggestion using WSJTX.. Thanks in advance for your help.

To add some context to this he has a sound card speaker jacked plugged into a MIC jack.  So, very easy to overdrive things  (MIC input expecting -60 to -40dBu, line level -10dBu, and speaker level +4dBu).  This is a common reason that operators generate harmonics on rigs that have audio plugged into the mic jack.
The same sound card works fine on his other computer (which I believe is Windows).On the new laptop (Linuix with pulse audio) the signal shows 100Hz wide indicating that it is clipped.  The SignaLink will provide analog control of the audio level which should work on both of his systems.

If overdriving is the issue, 3 resistors can create a 20db audio
attenuator. That may be all you need.

Dennis W1UE

Well, Mike Black, W9MDB, looked my system over today and recommended replacing the $10 external USB sound card with something more configurable such as a SignaLink. The current sound adapter is over driving the MIC port on my KX3. I appreciate the help from everyone and especially want to thank Mike for connecting to the system today and troubleshooting.

I'll call this request closed. Thanks...

I know this can be a deeper subject and not exactly about WSJT-X but the
various studies done seem to suggest that you use a 43 mix for HF baluns and 31 mix for HF chokes
See Balun Design's Web Site
See Palmar Engineering Web Site

Neither of these understand how chokes work. When I measured a Balun Designs product several years ago, it didn't look ANYTHING like their online data sheet.

Palomar sells the wrong mix parts.

See G3TXQ references

Steve (SK) was a very good lab tech, but he failed to understand that the very wide manufacturing tolerances of ferrite materials make the higher Q NiZn materials #43 and #52 unsuitable for HF chokes. I suspect that he measured only one or two parts of a given part number; I measured nearly 200 of one part, more than 100 of another, and more than 50 of a third. My take those tolerances into account. Steve's do not,
and when I bought 40 of the #52 cores he recommended, measured them all, chose cores at the limits of those I had measured, his recommendations didn't match.

Note that I have worked ONLY on common mode chokes.
