Speaker for the headset jack?

[Steve Crewdog]

Chasing our tail with a squelch problem, the GTR-200 does not have a speaker option so whenever I want to check for the noise I have to pick up my headset. Sure would be easier if there was a small speaker I could plug into the headset jack, do they make such a thing?


TIA

Need a transformer to match the impedance. IIRC the GTR 200 is looking for 150 - 300ohm, and your typical replacement paper cone speaker is 8ohms.

Adding a transformer will not provide the required energy to drive a speaker. A simpler and effective solution is a small audio amp. It will provide the high impedance input and low impedance output for the speaker while adding the energy to drive the speaker.

This one from Amazon will work fine: https://www.amazon.com/HiLetgo-LM386-Audio-Amplifier-Module/dp/B00LNACGTY

You will have to also connect aircraft 12V to the amp, or just use a 9v battery if only needed occasionally.

Even simpler might be an amplified laptop speaker which would be a speaker and amplifier in an attractive case. You'd need to use a plug adapter to go from 1/4" headphone jack to the 1/8" used by the speaker and still have to provide a power source, in this case a USB power bank will do.
