Hi- I am using (from this list, at least) a RACAL 6790/GM with the VLF EPROM and associated circuitry. This does an excellent job on NDBs. Off this list, I also use an ICOM-R71A and a JRC NRD-535D. These are also excellent NDB receivers which both give you plenty of options vis-a-vis bandwidths, pass-band tuning, notch filtering and so on. Ken Maltz Jericho, NY
