    Heck, it's ALL good when it comes to radio stuff! :D

    Download and use them all. I tend to prefer SDRuno but the others are pretty and fun to use.

    Don't forget to download the 1090 dump ADS-B program so you can chart aircraft near you. That's fun too.

    I'm not real tech-savy, so downloading all of them to play around would end up a mess. There are so many "bits-n-pieces" to all of these programs, they just confuse me.

    The IF is the "Intermediate Frequency" - a point in the receiver path that is well back from the antenna and protected from the transmitter output. It is a common place to pick up a signal to feed into your SDR and you should have no difficulty finding instructions on the web to do it and, quite possibly, an off-the-shelf kit add it if there is no existing provision.

    Depending on how you expect to use the SDR, there may be a big downside to the IF tap - it comes after a lot of filtering in the transceiver and that limits the frequency range that it can see. I use my SDR both as an enhanced panadaptor and as a second receiver. I have it tapped off the front-end of the transceiver and it sees the full RF spectrum from 1MHz to 50MHz or more - hence I can have the 7300 operating on 40m and switch the SDR up to 20m to have a quick look round for interesting activity. If you hook your SDR up to an IF tap in your 590, you will not be able to see outside the band that the 590 is tuned to.

    Not sure I completely understand why all of that is necessary. My Kenwood TS-590SG has an outlet on the back that the RSP-2 plugs right into.

    Is that an advertised feature? Does that feature have a description other than what might be obvious? I'd look for that in my future purchase if I didn't decide on an SDR transceiver...

    All I know is the folks who own the TS-590SG and connect SDR boxes to them say it is I have to believe it is. It's either the DRV or the RX ANT jacks. That's what happens when you don't know what you don't know. :D Sorry, can't help you more than that. Guess I'll find out when I get help hooking it all up.

    Thanks. It's not exactly the simply plug-it-in-and-play kind of thing I was dreaming of, but it's nice to know it can be done.
