Drake uses PIN diodes in the front end switched band filters of the R8
series (and at least the SW8); those diodes deteriorate over time,
significantly reducing sensitivity. Unless you had those diodes replaced
at your service it's likely that's why your Drake is less sensitive than
the Elad.

An OK morning for TPs in CO. I did a preliminary comparison between my Elad FDM-S2 and
the Drake R8A. As Bogey said "This could be the beginning of a beautiful
friendship". I started with comparing the two JJ powerhouses, JOUB and JOIB. The
Drake had weak, barely discernable audio with both the ALA 1530ln and the NW Corner-Fed
loop. The Elad produced fair to good audio readily understandable to a JJ speaker. I did
not expect the difference to be so evident. I had my R8A serviced a couple of years ago
by a former Drake tech, so while a bit long in the tooth, it's working fine. More to
come....
This morning's results:
594 JOAK w/male in JJ weak (w/Elad, just a het w/Drake)
747 JOIB w/male in JJ good (w/Elad, weaker w/Drake)
774 JOUB w/male in JJ good (w/Elad, weaker w/Drake)
828 JOBB w/ weak audio (w/Elad, threshold audio w/Drake)
A decent assortment of hets.
