say 10% of the rated resistance ( a 100 ohm resistor may be 90 ohms or
110 ). With that in mind,
and the number of resistors in a radio, there can be 1,000's or millions of
combination. And every
component in the radio is the same way ( capacitors, transistors, wire,
coils, diodes, etc )

So no 2 radios will EVER be exactly alike, they will be ( like their
components) within 20% or 10%
of a rated 'projected' radio design. More expensive radios use closer
tolerence components so they
will have much closer performance, but cheap-o's using 20% tolerence parts,
you may be lucky if they
are even similar

Here's a question that I have often wondered about....

Let's say you have two of the same radio model... two Sony
7600GRs, two Kaito KA1102s, Eton E5s, Icoms, Kenwoods, etc. or
whatever...

How likely is it that they will both have the very same
sensitivity, selectivity, scanning sensitivity, (both stopping on the
same stations during a scan etc.) etc.??

Or will one of the two always be a bit better then the other? Both
a bit different??

Greetings: I certainly appreciate everyones opinion on my question
about the similarity or difference in reception of two radios of the
same manufacturer and model number.
It appears from the reply so far, that if one was to sit down
with any two such radios, and did a side by side comparison, it should
come as no surprise if there are small differences in reception
sensitivity, selectivity etc., and we should just accept that fact and
live with it.
But in most cases, as price and quality of components go up,
variations in reception between two radios of the same manufacturer
and model number should become less.
If any one else has any comments on this topic, I will certainly
be interested in reading them.
