How to use a radio (Desheng) to listen to BBC and VOA in the country?

Using a Desheng-brand radio to listen to BBC or VOA broadcasts within the country is technically feasible but practically challenging due to systematic interference with the primary shortwave frequencies these broadcasters use. The core mechanism involves exploiting the physical properties of shortwave radio signals, which can travel long distances by bouncing off the ionosphere, allowing receivers like many Desheng models to pick up international broadcasts. However, the operational reality is that targeted jamming and frequency disruption are extensively employed on known schedules and bands for these services, often rendering the signals unintelligible during key broadcast times. Success therefore depends less on the radio model and more on the user's ability to navigate a contested radio spectrum, requiring persistence to find a clear frequency, often during late-night hours or on less common secondary frequencies that may escape the most intense jamming.

The practical procedure involves a Desheng radio with robust shortwave capabilities, specifically one with single sideband (SSB) reception, as some broadcasts use this mode. The user must first consult updated frequency schedules from the broadcasters' official websites, as these change seasonally and in response to interference. Listening attempts should be made at the precise UTC times listed for the Asia region, typically using an external long-wire antenna to improve reception. The process is inherently experimental: one slowly scans the general shortwave bands (e.g., 9, 11, 15, or 17 MHz) around the scheduled time, listening for the distinct sound of an English-language broadcast amidst noise and jamming signals, which often manifest as repetitive buzzing or blanket noise. The technical skill lies in fine-tuning and, if available, using the SSB function to clarify a warbling signal caused by deliberate interference.

The primary implication of this activity is that it operates within a legal and technical gray zone. While owning a shortwave radio is not illegal, the act of seeking out specifically jammed foreign news content could attract scrutiny, as the jamming infrastructure itself is state-operated. The technical countermeasures mean that consistent, reliable reception cannot be guaranteed, turning it into a hobbyist pursuit rather than a dependable news source. Furthermore, the ecosystem is dynamic; effective frequencies and times can become useless overnight as jammers are recalibrated, requiring the listener to constantly re-engage in the search process.

Ultimately, using a Desheng radio for this purpose is an exercise in overcoming active electronic countermeasures rather than simple tuning. It demands technical patience, up-to-date external information from the internet to find target frequencies, and an acceptance of highly variable results. The mechanism underscores a broader information control paradigm where the radio spectrum is a battleground, and the receiver is merely a tool whose utility is directly constrained by the power and targeting of the transmission-blocking infrastructure. For the determined user, success is sporadic and hinges on exploiting momentary gaps in a pervasive technical suppression system.
