Amazing Radio  Time owned: 3 to 6 months
I recently got back into shortwave radio after staying away due to the horrible urban RFI situation. I previously used a Drake R8 original. That was a great radio, but having a software defined radio is a vastly different experience.

The SDRMAX V software is amazing. It has a couple quirks, and it takes a while to switch from using dials for everything -- but the ability to view up to 2 Mhz spectrum and the selectivity makes it all worthwhile! The one improvement I most want to see is a better spectrum playback. Currently you can record and re-tune the radio. However you cannot jump ahead or back to a time in the recording. This makes reviewing a long recording very difficult.

The selectivity is superb. I don't know the specifications but it crushes the Drake. The synchronous AM outperforms the Drake (which had locking issues). You can vary the bandwidth in each mode to the nearest 1 Hz.

The noise reduction provides marginal improvements on weak signals. It is not a miracle. It also makes it easier to listen to signals that have moderate noise.

The two noise blankers are useful. NB2 is effective on power line noise. I can hear WWV on 60 khz thanks to NB2. They are quirky. At some settings, signals bleed all over.

I don't like the auto-notch filter as it appears to be too wide or too deep. However in practice, I never need it because you can avoid the heterodynes by using tight filters and USB/LSB. The manual notches work great and you can have up to ten.

The graphical display is very useful to find stations. For instance, it is easy to see Transatlantic MW carriers. It is also useful for determining what filter size to use, and for peaking or nulling a signal.

The documentation is limited. However there is support via a YahooGroups.

If you live in a city, you may see a weak image of FM stations around 30-35 Mhz (probably the 55 mhz low-pass filter is not strong enough). There are also several spurious signals that appear as multiples of the spectrum width that you are viewing - however they can be eliminated by changing that width.
