I picked one of these up and have been checking it out on AM. The hand mic sounds nasty, but using the line in and out audio the audio sounds very good RX and TX within its bandwidth limitations. The audio sounds clean and clear, receive audio is nice, its got what they call 6 and 9 Khz bandwidth choices. The width and passband tuning controls do not work on AM, why I do not know, not important enough to add I suppose...or maybe its the design. It has a 9 MHz first IF and the radio has an IF output that allows a NICE panadaptor. I hooked up my sdr-iq and it allows a 190 KHz display if you want it that wide, along with all the sdr features. TX audio sounds very good to me, it goes out to about 3 KHz or maybe wider, but it modulates well, 100% in both directions, and it will over modulate in both directions. It does not seem to sound bad when you do over modulate, nor does it get warm if you run it at full power for a while, no loud fans. Controls are semi nasty with not enough buttons, but you can manage. The tuning knob is very touchy and there is nothing you can do about it. The built in spectrum/waterfall display would have been very cool about 25 years ago, today its a waste of time. Its got three antenna ports, #3 can be a receive antenna port or a TRX port, the built in antenna tuna works on all 3 ports withing the typical 3-1 range. The receive audio sounds much better then the icom 7300 as it goes below 100 Hz, and the TX AM is better as far as modulation goes, easy to hit 120% or more positive. I worked Joe (N4RXV) down in Georga for an hour last night on the 3000 at 25 watts carrier into the G5RV antenna solid copy both ways, when I went to the 200 watt rig I came up 2 S units he reported. These radios are about half the cost they were when they came out, maybe the icom 7300 has caused that. For the price (new) they seem worth it for this kind of radio. It does not TX 5000 Hz but otherwise sounds very good to me for a modern plastic box radio. Its not as fussy in adjustment as a flex 5000, it modulates better then the 7300 and the RX is MUCH better sounding. You could put a good microphone in the front and use the built in EQ and have a better sounding AM box then most others..
