The ICF-2001D can really fill its owner with enthusiasm: Very good reception on all bands without any large signal problems. The synchronous detector with its selectable side bands is a highly effective tool for unsteady frequencies. SSB works very well, too. Receiving marine radio without the air bands on shortwave is no problem at all. I connected the ICF-2001D to my Wellbrook ALA1530+ antenna and compared the results with my table top receivers.
In conclusion, it can be said the Sony ICF-2001D is still a superb receiver. Not without reason, the synchronous detector is very popular. The ICF-2001D is easy to operate and is solidly built. When you see this radio in a nice and operational state, you should get it.
