While some portables will work with reasonably stronger signals, the more complex the signal (or conditions), the more a portable will fall short.

There are many ways to accomplish this without going through the expenditure of having a dedicated interface, although one is often used in the amateur service. Please see our [[Connecting Radios to Soundcards]] article for more information.
