Show correct transmit passband in panadapter

I was having trouble understanding why I couldn't transmit JT9 last night with a 3k offset - everything looked OK - I could see the signal being generated by WSJT-X in the panadapter, but there was no RF out. My mistake was that I while I had set the receive passband to 5k, I hadn't also adjusted the transmit high cut filter, which was incorrectly set for 2.9k. I now have profiles set up to manage this, but... I'm wondering if it would make sense to have the passband indicator (or some other indicator in the panadapter) show the correct transmit passband when tuning or transmitting? Also seems like a cool way to show what Flex can do too...

    Hi John. This has caught me out before, I always use the 'fake-it' split mode now as that will always ensure that you transmit around 1.5khz!

    Hi Phil - Thanks for your response! If I understand it correctly, if your dial is set to 14.076 mHz and you want to have a JT9 QSO say 3.6 kHz above that, the 'fake it' split mode within WSJT-X will automatically change your dial frequency via CAT while you transmit to 14.078 mHz, using a 1.6 kHz TX offset to put you at the same spot, and then change your dial back again to 14.076 with a 3.6kHz offset for RX via CAT when you stop transmitting. I think this is a great feature, and you are right that it gets the job done for simultaneous JT65/JT9 over a wide tx/rx range. I think my suggestion, about what the panadapter displays encompasses more than WSJT operation however. Here is the case... when in RX the Flex panadapter shows the RX signals, RX waterfall and RX passband graphically (very cool!). However when you go to TX mode the panadapter shows the TX waveform, and the TX waterfall (also cool!), yet it is overlaid with the RX passband. To me this is inconsistent.

    For some modes, it would be very useful to have an RX pass=Tx pass button

    Took too long to edit the above post.

    To continue...

    It is very confusing, especially when starting, that there are several places to seemingly adjust the same thing. With passbands, I feel that both Rx and TX passbands should be adjusted in the same/similar way and in the same place in the GUI. Why not a separate side panel for passbands where they can easily seen and adjusted?

    Guy, Agree with you on the goal of making it less confusing. I think that is more important than implementing it in a certain way.
