A simple RTL-SDR receiver can be used to receive marine weather forecasts. The unit is small and inexpensive (approx. $25). It can be controlled by using the software program SDR# or other similar programs. The picture above shows my unit plugged into the usb port on the left side of my laptop, the display shows Weather Radio Canada station XMJ-225 on 162.4MHz. The picture below show a simple whip antenna on my apartment balcony.
