I was looking for a vhf am receiver for aviation band, using an aor 8200. Just nothing can be compared. This *old* sx400 does it far mor better, in sensivity and snr. I've put my aor away and use this old stuff instead. The only drawback is the slow scan rate that may cause lost of reception. And of course, as an old scanning device, it does not show impressive feature level. Having said this, I will not change it for a new one.
