I was fascinated by this radio when I first saw it in new conditions at a hamfest. I did not have enough information to buy it, I googled and found the technical manual, I youtubed and listened it! I pretty much liked the sound, bit metallic but crystal clear. Then I decided I had to buy it. You can find the very same units at very different prices, an average price is about 500 euro (with the battery pack for external 24VDC, batteries not included) for what I have seen but the price mainly depends on demand and supply and I believe this unit could become quite collectible in the near future.
I think that this radio is ideal for newcomers in the world of amateur radio. The radio was thought to be operated by humans without much technical background. For example, there is no S-meter. I think a radio without an S-meter could be a great innovation in amateur radio but I am aware that not everybody would agree. There is no tuning knob. Another great innovation! No noise blanker! No notch! No 100 watts (just select 2 or 20 watts) No everything but an internal ATU (at least in my unit) that can tune a rod 3.3 meters high from 1.5 to 30 Mhz and virtually any antenna and longwire.
Performance: the receiver performs very well. I like its architecture: high first IF at about 40Mhz, a roofing filter, and the second if at about 9Mhz. The receiver however not always handles large signals outside the band. The ATU sometimes helps, but if you operate in CW with the ATU, the first dot transmitted is lost as it tunes the ATU, and then in CW I prefer not to use the ATU whenever it is possible. I use the ATU instead on SSB. Compared to the Drake R8, using the same wideband antennas, a T2FD, the R8 is virtually immune from intermodulation while the AEG sometimes would require either an attenuator or a better preselection. The level of intermodulation by the way is minimal.
The audio is crystal clear, the volume will not fill a noisy large room with people chatting. The output is just 2.75V on at least 100ohm load. An high impedance speaker and high impedance headphones are required. Alternatively the soundcard of a PC would work very very well. Noise reduction, audio dsp can be done entirely by the PC.
The transmitter requires a balanced to ground microphone. I checked different capsules; dynamic ones seem to me to better match the input. To my surprise, crystal or ceramic capsules don't seem to match very well. With only 20 watt and the folded dipole I got however good reports.
Overall impression: the unit is built like a tank, can be operated from -40 up to 70 degrees, can be put into the water (according to the manual) at 1 meter depth for 2 hours, looks very nice, it is extremely easy to operate, there is a technical manual on line, the connectors are a bit difficult to find: these are mil connectors and expensive ones. I paid 12 euro for the DC connector, and 30 euro for the audio mike connector (I needed one, albeit there are two audio connectors in the radio, as they are identical). I spent 30 euro because I bought a 6 meters German military radio with micro and headphones with this connector!
