60m band TX not ready. Interlock preventing transmission

Raul Pla

I was able to add 60m 5357 Khz on WSJT and work a few contacts 2 days ago. Now I see the TX not ready message on the lower right on SSDR on the radio desk. I hit the tune button on WSJTx and get the interlock message. What did I change or what happened?

Aside from WSJT, I used to Tune (transmit) from SSDR OK on or around 5357 before. software is 3.8.19 as nothing else has changed.

Odds are you have your transmit bandwidth set too high and have the possibility of transmitting out of band.

Somehow, you have changed your High Cut (the audio Low Pass Filter) to more than 3000hz.

If you step it down, you'll see that MOX and TUNE will be - ungreyed.

I have the same issue with V3.8.20. I don't normally operate on 60m but checked it after your comment and have the same interlock message.

This is typically caused by having your transmit bandwidth set too wide. Try setting the high limit to 2800 Hz and see if that fixes the problem.

Thanks Mike, you are right. I had the high cut at 3100. However I had not looked at that pane because it's on the PHNE (phone) button at the top of the group. Now at 3000 SSDR will transmit.

At the slice flag I found the DIGU was at 2.0K which I think was me poking around before I posted a message. That's back to 3K now.

WE learn something new on SSDR all the time. Len was right as well.

Ok gang. Heres the secret. Set transmit to 5.357 digiu. Move your transmit low cut to 1500hz. set your high cut to 2000. You will set fake it on wsjtx sorfware. Receive can be set 100 to 3000... you can now use any reasonable 200 to 2900 transmit offset and even run fox / hound on ft8 in that window without locking out. You might want to create a 5.357 trans profile... do not forget to put your transmit bandwidth back to normal if getting on ssb. Have at it guys... Erika Poo K0DD 60m Diva

Erika's solution will work but really isn't required on a FlexRadio since the Transmit bandwidth is flat. I believe the transmitted signal is still within the legal 3khz bandwidth. (I need to think about this one more).

It would only be required for situations that might take you beyond the dial frequency beyond +3000 hz.
