You can run a dipole between two houses, just be sure to do your RF exposure calculations and don't be surprised if you pick up a lot of RFI. You will need to use insulators between the antenna wire and the supporting rope. There is a lot of voltage on the ends of the dipole. If the dipole is less than 1/4 wavelength off the ground, most of the signal will go up. That's good for NVIS on the lower bands, but bad for DX.

You can put multiple dipoles on the same cable, it's called a fan dipole. The wires have to be spread out and can be a pain to work with, but you can get an antenna that's resonant on multiple bands.

The Yaesu FT-60 is a good choice if you only want analog FM.

SDR++ seems to work the best with my RSP1A, I still have to use a closed source driver that hasn't been updated since Dec 2019. At least the driver works fairly well, but sometimes it locks up and the sdrplay service has to be restarted.

The Android driver, on the other hand, is completely broken. It usually crashes within 5 minutes and it only supports up to 2msps. They haven't updated it since Feb 2019.

It works, but it's closed source and pretty basic. I just wish they would release an open source driver.
