locked FST4

Greetings.
I have downloaded and installed the latest version of WSJT-X with the aim of entering its new digital mode FST4, but I can't see anyone transmitting. I request help to start working in this new mode.

Several users in North American on 40M in this evening using the WSPR frequency BUT transmitting at  2000 Hz and the "F High" setting adjusted to 2000 Hz.

I request help to start working in this new mode.
Wilfredo,

You could post here https://wsprnet.org/drupal/wsprnet/chat

Someone will join you or give advice.

As far as I could understand in the mail, I tried to do what I show in the image I send you, and I didn't get any results.
Is there anything else I should do?

Wilfredo: I did a search for " WSPR Frequencies " and wrote them down. Apparently, FST4 is being done on WSPR frequencies, although I listened last night to 7.0386 MHz and only saw WSPR signals; no FST4 seen. Nor on the alternate freq of 7.04 MHz. Then I went to 80 meters, to WSPR frequency of 3.5926 MHz, then 3.594 MHz, and, again, saw no FST4 signals. So I am at a loss, also, as to where the activity is.

That's exactly what I'm saying, I've been looking for signs for several days and I can't find them. Maybe someone from NA who is relatively close to me and is coming out in fst4 could tell where they are transmitting and the requirements for it.

David,

a QSO mode like FST4 should not be used in WSPR sub-bands, the only exception to this might be on LF and MF bands where often transmitters have very limited bandwidths, or even fixed single frequency. Note here MF means 630m and LF means 2200m. Where transmitters and receivers can be readily tuned to different frequencies then please do not use WSPR sub-bands for other modes, the WSPR network is extensive and often using specialist hardware in unattended operation with quite low QRP or QRPP power levels, it provides an excellent propagation probing and research tool.

FST4 and FST4W are targeted at MF/LF bands where the path frequency stability is likely to be suitable for the close tone spacings used with the longer T/R periods, at HF frequencies Doppler spreading and transmitted stability is less likely to favour FST4 over modes like JT9 and similarly FST4W vs. WSPR.

Please experiment with these modes and report back how it goes, but QRM to other modes must be considered and avoided where possible.

Bill, there was an email sent out last night that reported that FST4 was using WSPR frequencies on 40 meters, but that the audio frequency of 2000 hz was used, which should mean that it would not interfere with WSPR stations. Is that incorrect info?

Greetings again.
someone to send me in images how I configure my wsjt-x to receive and transmit in FSt4, I am feeding myself with their theoretical knowledge in this aspect, but I can't hear anyone in this mode. However the rest of them do. (FT8, MFSK_FT4, JT9, etc) that is, what problem with radio-antenna I don't have.

For Dave, AD4TJ: The 80m WSPR freq changed months and months ago. To keep abreast of current WSPR happenings, please see http://www.wsprnet.org. The current 80m WSPR freq is 3.5686. Occasionally I still see a station on the old 80m WSPR freq, however they find themselves all alone due to not staying informed.

Best regards,

Hello,

Interesting. Here in the UK 3.573 is very busy come nightfall.

In the US( and everywhere? ), 3.573 is the FT8 frequency.

Still looking for the answer to my question:

FST4 was quoted as being used on the 80 meter WSPR freq, but with 2000 hz being used. Does that or does it not interfere with WSPR stations at 1500( or whatever freq ) hz?
