[R-390] Hi

[John Kolb]

As Navy Radiomen, we only called them 390's also. Even
though every one we had was an 'A. Wasn't a problem there
as everyone knew want we meant - and for our purposes,
they would have interchangable.

However things are different here in this group - many
of the messages asking techenical questions will get
different answers depending on if they are asking about
a 390 or 390A. Since so many people have said 390 when
they were refering to a 390A, unless you know well the
person asking a question about a 390, you won't be sure
which they are really asking about.

If I post an ad asking to buy a 390A IF strip, everyone
knows exactly what I want. If I ask for a 390 IF strip,
and really wanted one for a 390A, I've just wasted
everybody's time plus maybe even end up buying the wrong
part. Even if I really wanted one for a 390 non A, someone
who might have sold me a 390 IF strip may not bother answering
assuming I'm one of those sloppy people that calls everything
a 390 and probably really want one for a 390A. However
if I ask for one for a 390 non A, everyone will be sure
exactly want I want. So I will always consider references
to 390 non A's to be in good taste and an aid to clear
communications.

To answer a different message also:

I don't recall ever hearing about the SRR-11A series with
mechanical filters, but it's just random luck that the
A in SRR1xA, R-390A, and R-388A all indicates mechanical
filter versions - doesn't mean you can buy any radio with
an A in the name and find a mech filter.

Speaking of filters, I have some mechanical filter info on my
