Hello Terry,

Before reverting to SDR's, I used a W&G SPM-30 for NDB hunting at 
LF. The unpleasant high pitch of 2000 Hz was changed  to 500 Hz by 
either using a hardware downconvertor or a different internal X-tal.
To get rid of intermod problems, I used a tuneable pre-amplifier.

This set up worked very well indeed, especially due to the 24 Hz 
wide banwidth setting.
