I have never seen detailed technician specs on the HQ-145 and I have looked
many times.  I don't think Hammarlund started publishing meaningful specs
until around the introduction of the HQ-170.  But what I've seen on the
bench many times throughout the years is that the  145 on ssb hears about
-116 DBM for 10DB S/N.  AM is around -104DBM.  On the highest band I
usually see around -107 for SSB.  Note the sensitivity is reduced about
20DB on the BCB which I suspect was Hammarlund's way of dealing with the
high level signals on the BCB.  Hope this helps.  73  Dave
