Re: Frequency shifts down 500KHz on transmit

You should NOT turn split off. You need Split or “Fake It” to ensure a clean TX signal, unless you only every TX above 1500Hz.

Mine does as well, as it should when the audio component of the sent transmission falls outside the optimal passband of the transceiver. This is to ‘push it back’ to where it is within said

Fred,
the way WSJT-X uses a different VFO dial frequency for Tx is not a problem that needs solving, it is an important feature that ensures your signal is as clean as possible, which also allows you

John,
Regarding the shift, the VFO frequency remains constant on my FT-DX3000 between transmit and receive. I would check two things:
1) Make sure you aren't in Hound Mode.
2) On the settings tab,

Re: Frequency shifts down 500KHz on transmit

do you have additional software for time sync. check your clock at time.is to see if your clock is off greater than 2.5 seconds ( critical)
try using dimension4, meinberg, or any other available

Re: Frequency shifts down 500KHz on transmit

A shift of 500Hz (that’s HERTZ not KILOHERTZ!) is completely normal. It allows the program to generate the tones at a higher frequency to keep harmonics outside the TX passband.

Are you sure it shifts 500Khz !! thats going put your signals way outside any band we have I fear !!!
Not being an expert, but the only time I have noticed a similar problem with decodes, is that

Re: WSJT-X LOSES TUNE AND XMT CAPABILITY

I agree with you and Peter, it is definitely not RFI.
I lost the output with 1 or 2 watts output from my FT-857 and even lost it while transmitting into a 50-ohm load. Sometimes I can switch back

Everything was working great, WSJTX, JTAlert and HRD LogBook.
Then there were no decodes the next operating session, no Windows updates to interfere.
I hear and see loads of signals but no activity is

Raspberry PI
#general
Hi
I have over the years used a RPI for WSJT-X, mostly for FT8 and MSK144. The "speed" of the RPI is on the margin but when #4 was introduced I had no issues to run WSJT-X in deep mode

Hi Bill, Regin hope you don't mind me replying.
I have discussed this very briefly on
ON4KST chat.
In these chats we are asking Regin to try q65 so I think he is trying to install 2.4 or later

But at such a low -24 dB signal/noise ratio it is

As Bill said, only QRZ and CQ is watched for.
You also don’t say whether you decoded the P5 or not. One thing for sure, if you don’t hear him, you can’t work him and it shouldn’t say

is there activity from p5 at all, or was this maybe a false decode? why have an alert for a station you are not hearing??

Hi Wes,
P5ABC would have shown up earlier for you, when calling GW3DEF, and would have been highlighted. Good luck with the pileup!
You might also want to look at JTAlert.
