$200 each? Yikes!

Found it...a bit pricy but could come in handy.

Thanks for finding that. I can't view that at work due to ebay being blocked but I will
look that over when I get home.

These work well and isolate the input from ground (very important for some Motorola radios). I'm currently running 3 of them in my truck. I feed them into the Kenwood KES-5 40 watt speaker. Nice units!

I've only looked at the last few posts so if this has already been covered, sorry 'bout that.
This sort of thing was covered several years ago in one of the electronic magazines. Basically a 'home-brewed' thingy using common parts, not really all that difficult to put together. Can't remember which magazine, sorry.

That was my next question. Currently I have no motorolas in my newer car, just a kenwood TMV71A and a BCD996XT. I have each running to a 15 watt amplified motorola speaker. My problem is the 996XT has weak audio even into the amplified speaker but the Kenwood TMV71A is loud. Both claim 2 watts audio output but I know the scanner is less. How does the KES-5 speaker perform?

[mrweather]

I feed my TM-V71A into a KES-5 and there's lots of audio. The internal speaker on the radio is almost useless in a vehicle environment.

Back on topic... I'm sure the Fleet Radio unit is an excellent product but man, that's a good chunk of change.

The fleet products device has an amplifier. Using that a 996 into the KES-5 works great. I'm running a mixture of radios but 5 of them are 996T/XT's and I run the volume control on the radio at 50%.

Strange in that the web site is useless and mentions nothing about these
units and they only seem to sell them on ebay. I agree that they are nice
units but they are rather expensive. I seem to recall when Fleet Radio
Products sold them they were in the $150 range. Now they are charging
$225 on ebay.

I found another post on here that shows a picture of an older unit with the URL on it. That site no long exists.

The eBay listing here has the below URL but it's dead too.

I was looking at maybe getting one until I that their website(s) are down. Makes you wonder if they went out of business and someone is trying to unload the units on eBay.

Just use audio transformers, 600 ohm 1:1 transformers (found in all kinds of old electronics, modems etc). Wire the 4 (or any number) of transformer secondary windings in parallel (or series but the level will be lower - us this if feeding an amplifier to keep the impedance up... ).. then wire each individual receiver output into each individual primary windings of the transformers. Pri/Sec applies to audio transformers... Pri/Sec doesn't matter for a 600 ohm 1:1 transformers...

So I bit the bullet and bought one of these. No complaints, the product works great. Yeah I could have probably built something similar but this was my easy way out. I found the sound quality a bit better with a 3.2 ohm 30 watt Motorola speaker as opposed to the 8 ohm 40 watt Kenwood KES-5 speaker. I'm only running two radios so I have the option to run two more if need be. If I only had the room for two more.
