Therein lies a problem; I had considered the use of 270MHz
SAW filters as used in GSM phones as RX roofing filters, but
with the deign of GSM phones moving en masse to direct
conversion, that's not possible.

One area in which we can assure some degree of future proofing
is to define the interfaces between the sections so that any
section could be replaced by circuitry of your own making
and/or of your own repair.

Excellent idea. Let's make it a high-quality job, though;
uncompromising on sensitivity/selectivity/noise etc. And use
ubiquitous, easily-available components that will be around for the
foreseeable future to come to permit serviceability over the long
term!

Dear Airy,

I can't resist the temptation to read most of what you write. It's habit
forming.

It's because there appears to be an unexpected element of truth in many of
your thought-out if unruly statements.

But try not to be so offensive in your, chip-on-the-shoulder, mode of
expression. You could be even more effective.

Reg, break the habit.

You won't miss much.

Dear Reg,

Thank-you for your few kind words.

I, in my turn, read with interest your contributions to the
various NG. From what you profess, I have much to
learn about the common sense of what really happens
in antennae and feeders and I am an avid pupil of yours.
(That is part of parcel of Ham Radio, not only to
improve one's own knowledge, but also to encourage
others in what is essentially a technical pursuit.)

As to offensiveness, none is intended. If it was your
intention to refer to my stance against the gangrenous
degeneration that is the M3/CB Fools' Licence scheme,
then I regret that I can offer you no apology. We Radio
Hams must take a stand now, and that stand must be to
refuse to have anything to do with what are essentially
second-class citizens in the radio context.

In other matters, if you do indeed refer to other matters, I speak
my mind and I speak the truth as I see it. Do not be so
surprised at candidness and openness. (If there are those
who take the liberty of taking offence at ideas expressed
that are not their own ideas, then they would be well advised
not to read an international forum such as this NG.

Caveat Lector.
