WR400 problem
« on: July 06, 2025, 02:30:34 PM »
Hello! I need some help with my Midland WR400 NOAA Weather Radio, Me and my husband are partly deaf and have a really hard time hearing the emergency alert when it goes off. I know midland has a strobe and pillow shaker but those won't work for situation. I bought their 21-406 external speaker, but its not working as intended even though its connected to the external alert hole. I there something I can do to make this work or do I need a different brand of weather radio?

I don't have a Midland WR400, so I could be mistaken. But, I see that the WR400 owners manual makes no mention of an external speaker option even though it does mention other accessories ( a strobe, and an external antenna). It may be that the "External Alert Jack" is only intended to drive the External Strobe accessory.   Personally, I'd plug a headphone into WR400 headphone jack to to test if a normal set of headphones (with a 3.5mm plug). If those work, then something like a "powered" Computer Speaker Kit would probably do what you want.

Something like this is what I am referring to: https://www.walmart.com/ip/onn-Stereo-Speaker-with-Volume-Controls-3-6-ft-3-5mm-Aux-with-USB-Power-Cable/803187184?classType=REGULAR&athbdg=L1200&from=/search
Note you need a USB adapter to power that kit. Or choose an integrated unit that has a builtin power supply.Please test the headphone jack before you buy anything else. And if that works, perhaps you could borrow a "powered" speaker to test that, before buying anything.

The 21-406 external speaker looks to me that it expects to have an amplified signal feed, and it appears that is not available in the WR400. The speaker page says "Compatible with Midland MXT500, MXT115, MXT275, MXT400, MXT500, MXT575, 1001LWX, 5001Z" so you could look at those units.

I tried the headphones hole as well still no luck,

Well, the headphone jack is not likely to drive a normal speaker.  If you are going to test the headphone jack, you would need to use headphones.

AFTER YOU HAVE CONFIRMED THE HEADPHONES WORK, then you could test a POWERED speaker kit.

[unpowered] Speakers require a higher signal level than headphones, which is why they are normally not interchangeable. "Powered" speakers have an integrated amplifier, so they can take a headphone signal and amplify it to drive speakers.
