A variometer is a device used to indicate whether you are ascending or descending when other cues are inadequate. It works by detecting the difference in air pressure at different altitudes, and in this instance sounds beeps of varying tones and intervals depending on rate of climb. It also sounds a warning tone if you are descending fast.

This is linear sliding design in this design. Linear design of coils has larger coil sliding over top of two smaller coils to allow tuning. Construction of sliding variometer is plastic pipe 1 inch inside diameter or 1.25 inch outside diameter about 8.5 inches long. Wind number 22 enameled wire 2.25 inches long or 86 turns.

You can make a fairly simple audio oscillator that has the pitch of its tone or the pitch of its beeping varied by a signal from the variometer. It might drive you crazy. But you would need to post the schematic of the variometer for us to see where to connect the V You might need to measure and post the voltages in the variometer circuit.

DIY friendly, cheap, fast and accurate audio-only variometer using widely available off-the-shelf modules, so minimal assembly required. Features : uses earthframe-z acceleration computed from MPU9250 data, and z altitude calculated from MS5611 barometric pressure, for a "zero-lag" variometer response

Any AM/OOK TX/RX can be used, but I had most success with the 433MHz modules from RF-Solutions. Much better than the cheap Ebay ones. The RX audio is fed to a portable, battery operated FM radio. I build the RX into the radio, and connected the audio to the FM radio's volume potmeter. See attachments for schematics.
