SDS200 no audio

[n1chu]

My SDS200 will loose audio but turning it off and then back on will correct it. I run an external amplified UNIDEN Bearcat speaker and have not disconnected it from the scanner yet. That’s because the radio is buttoned up inside a console in my vehicle and before I start digging into the console I thought I’d first ask if others are experiencing my issue. If it continues I know I will need to remove the scanner and place it on a test bench... checking the external speaker, etc.

Does the speaker meet the requirements listed in the manual I know it is no the simple 8 ohm 4 ohm output on the scanner.
PAGE 14 from the user manual.
CONNECTING AN EXTENSION SPEAKER In a noisy area, an optional amplified extension speaker, positioned in the right place, might provide more comfortable listening. Plug the speaker cables 1/8-inch (3.5-mm) mini-plug into your scanners back-panel Ext. Sp. Jack. Warning! If you connect an external speaker to the scanner’s Ext. SP jack or headphone jack, never connect the audio output line to a power supply and ground. This might also damage the scanner. All audio output is Class-D amplified (PWM). Never connect Ext. SP jack or headphone jack to an external Class-D AMP

Since the external amplified speaker is a Uniden product, was recommended as the one to use by Uniden, I believe it meets the requirements stated in the manual. Add to that my never reading any cautions when using it on the SDS200 and I think its compatible. I doubt my issue has anything to do with the external speaker. Thanks for the input... at this stage everything is suspect.

Might be worth disconnecting the speaker to rule it out for sure

If possible look at the ground spot for your speaker make sure it's power is grounded to battery or frame is good.

As it is an amplified speaker it might have a turn off circuit that switches off the speaker at lower sound levels.
It could be something wrong with that function so yes, run the scanner without the ext speaker as a test to rule it out.

If that is a Uniden BC23A speaker, the amp shuts off with no audio. I installed 10K resistors in mine to keep the amp on and prevent upcutting the audio.

I have two amplified UNIDEN speakers, one with a light that is lit while active and one without the lamp. I don’t know if both operate the same way with one minus the lamp. But I believe the external speaker is probably not causing my problem. However, it’s something that must be checked definitively before being eliminated as a possible cause. I was hoping there were others that experienced the same as I would come forward. Thanks for the info. QUOTE="tvengr, post: 3248247, member: 1243946"]
