I assume you want some positive reinforcement to make you feel
good about owning this receiver It get's a five star rating on this
site:

Regarding the set only being single conversion on the lower frequencies,
that is not a problem. The double conversion provides improved
image rejection on the higher frequencies, but single conversion
probably offers stronger signal handling capabilities (less likelihood
of mixer overload.) Enjoy the radio.
