I know this is an ancient thread. Couldn't resist.
Meduci''s radio (the current model) did sound good when a ham operator came to our station last month and parked in the parking lot. He ran one on his dashboard, and I will say it was good. However, the previoius model had some issues. The owner of that company provided us with one to stream and promote, but it had a whistle in it. Didn't matter if it was offsite or on, we tried it from the Ionia Freefair, and it whistled. He DID take it back, and was very gracious about it, as our original agreement was to help each other through mutual benefit. I will say, on brief listen in a vehicle with the (newer model) radio directly plugged into the sound system the ham had in his car, it was a decent rendering of WION's wideband sound.
Since the postings above, we have ceased using a Carver and are using a professional product called the "Potomac Instruments" AM stereo mmonitor to provide the stream. This is the company that also manufactures the devices we measure our AM signals and arrays' patterns-with. There are plans in the works to tune-up our night 3-tower array to equalize the sound offered and better balance the stereo effects when we're using the array and not the single tower.
If I had to choose a receiver available fairly easily on the secondary market, I'd recommend Denon's TU-680(NAB)...we use those in our main studio, engineering, and have found them to be stable, able to handle high signal levels, good high frequency response, good lows, and no need for a switchable NRSC filter which the Carver had. The Carver was too bright with the NRSC filter "out" and we had to filter it for streaming, and was too "dull" if switched in. It's a joy to hear what the Potomac Instruments' does for our station's stream.
If I think of it, we'll let you know when changes are made. I've been away from Satguys too long, but will be reading more in the days to come.
