There have been a small number of interesting threads over the past few days on the subject of digital modes that are typically operated without narrow filters. PSK31, JT65, and FT8 are examples of modes where people tend to congregate on a specific dial frequency, and then spread out their signals by placing them in different locations within a USB passband. Most of the (box with a knob) radios I have used limit the USB passband to 2800Hz or 3000Hz, but I have noticed that SDR dongles tend to have much more flexibility to select wider passbands without changing the mode. E.g, running GQRX with an RTL-SDR, I can easily select 7kHz or 15kHz, or anything in between. The (software) receiver doesn't care how wide the passband is, as long as the output audio device operates with high enough sample rate so as not to alias the data stream when demodulating. I have used that feature to copy several modes at once, e.g., FT8+JT9+JT65, all with a single receiver. Having such a wide bandwidth seems like a great feature for people who want to listen to lots of adjacent signals at once. So how many of you have transceivers that can operate USB with the receiver wider than 3kHz? Could you share the make & model with us? SDR, box-with-a-knob, or combinations -- I don't care, I'm just curious what's out there.
