As I recall, Tim, the 515 was not cheap (compared to other rigs people
wanted at that time). The 515 has a solid receiver, same basic design
as the Triton IV, probably some improvement over the 509 (though I used
both and enjoyed them equally). I believe demand was not there for the
515.
The only thing I always do to a 515 that comes across my bench is to put
a second 4 pole filter in line for the receiver (giving a total of 8
poles filtering). This allows the nice transmit audio to continue, and
I find that it vastly reduces the blowby I usually experience with
nearby strong signals. I always suspected this to be a physical
coupling problem, because when I stick in the 4 pole filter at a
slightly different spot in the IF chain (down towards the RX), it
completely disappears.
All in all, the 515 is a very fine radio. Anyone have a spare for sale,
now I want mine back.

I would very much like to hear anyone's experience with the Argonaut
515 and any produced for it. I understand that only about 800 were
made. Does anyone know why the run was only 800 and how the rig was
received by the ham community when it was introduced? Thank you in
advance.
