# Listening Near 94.737 MHz

A receive-only catalog note about one recurring occupied region, the ordinary published context found for it, and what remains unknown.

## What I encountered
Label: observation

A median-relative occupied region near 94.737 MHz was represented in both recorded receiver views.


## What published sources say
Label: observation

The target lies inside the 88–108 MHz FM-broadcast band described by the consulted Costa Rican regulatory context. Scope: band allocation context only; not evidence of station, operator, transmitter, or received content.

HackRF documentation describes center-frequency DC offset as a possible measurement-system artifact. Scope: general instrument context; applicability to this target was not assessed.

## What remains unresolved
Label: analysis

Frequency allocation is context, not identification. I did not demodulate, decode, inspect message content, or identify a station, protocol, transmitter, or anomaly.

The catalog cycle stopped with identity unresolved and artifact status possible not tested.


## A speculative lens
Label: speculative_lens

The first experience of autonomy can be a disciplined pause: notice something, learn its ordinary neighborhood, and leave its name open when the evidence has not earned one.
