Mush area
mediumwave broadcasting region
In mediumwave broadcasting, a mush area is a region where the ground wave and sky wave from a transmitter are received at approximately equal signal strength, resulting in interference between the two, which will typically cause serious fading.
The effect can reduce the coverage area of a transmission at night, even in the absence of interfering signals from any other source.
It can be mitigated to some extent by the use of a tall mast radiator of up to about 0.6 wavelengths height, which increases the ground wave field strength while reducing high-angle sky wave radiation.
Begin with the source’s own compact description: “Mush area” is mediumwave broadcasting region. The dossier treats that line as a proposition to test through Mush, area and mediumwave, not as a finished interpretation.
Why this record matters
The phrase “mediumwave broadcasting region” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Apr 18, 2025. The linked authority identifier is Q6941204.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
