Slightly OT but people like Mal and Jim may have an answer. Is there a "modern" (i.e. can you buy it new today?) headphone set that is extremely sensitive in the same way that the old DLR5 headsets were in terms of efficiency converting AF to sound pressure in the ear? I believe Jim M0BMU claimed 2uV audio power could be heard using DLR5 headsets in his passive mechanical SAQ receiver. As DLR5s are more difficult to find these days I was wondering if there is anything as sensitive, or more so, around "new". 73s Roger G3XBM -- http://qss2.blogspot.com/ http://g3xbm-qrp.blogspot.com/ http://www.g3xbm.co.uk https://sites.google.com/site/sub9khz/ |
