But all the data modes interest me, and perhaps others. If someone would be kind enough to list what hardware might be required for the transmit side of NO-84's PSK-31 capability, it sure would be appreciated. (low-cost options preferred!)
One thing that you might want to consider is getting a 10m-only transceiver. There are several inexpensive ones from Chinese manufacturers, such as the Anytone AT-5555. These will cost around 100$-150$ and put out up to 20W or so.
I don't know how easy it is to input audio from PSK31 software into such a radio. Holding the mic up to your speaker may be a good start.
And to find a cheap 10 meter vertical: have a look at CB antennas. Most will cover 28 MHz.
I did the experiment with transmitting to NO-84 using a dipole in the attic and found I needed 20 watts on HF, see http://idefix.net/~koos/newsitem.cgi/1433017519
