Post by Peter WieckPost by John ByrnsI am curious why you want an SW transmitter given that the TO also
receives the MW broadcast band? I can see the need for a SW transmitter
if one is working with SW only radios, but it seems lees important when
the radios in question include the MW broadcast band.
For the same reason I have an FM transmitter even though I could
simply play whatever CD I wish at the location I wish rather than
running a separate transmitter.
Because I can. "Need" does not enter into it.
Of course "Need" doesn't enter into it, "Need" doesn't enter into
anything discussed in this group, at least On Topic discussions. But we
usually have some reason, or rational, for our wants and what we are
doing here.
Post by Peter WieckAnalog radio one way or another is on its way out in any meaningful
form. With few exceptions, most of it is canned and mindless, what is
not is often not to my taste. So I would like to have the capacity to
actually have meaningful noise come out of my vintage equipment into
the future.
What I was curious about was why you don't just broadcast to the TO
using a MW broadcast band TX? I will interpret your answer above as
meaning that your reason is a desire for completeness.
Post by Peter WieckUnits that will accomplish what I need run anywhere from $40 or so,
much cheaper than kluging an SSTRAN.
It seems strange that $40.00 could accomplish what you "Need" given that
you have rejected the $40.00 solution for the MW band, in favor of the
SSTRAN, why not also use a $40.00 TX for MW?
Without digging out my SSTRAN manual it is not clear that modifying an
SSTRAN for SW operation would be a "kludge". The changes to the VCO and
antenna matching networks would be a simple replacement of a few parts
with similar parts of different values. Even some commercial broadcast
transmitters used to require this sort of component change to operate in
different parts of the band. The only possible "kludge" would be if it
was necessary dead bug an IC to modify the frequency divider chain, but
the existing ICs might have the capability of doing the job with a minor
wiring change which might involve as little as cutting a foil and adding
a "greenie". I will have to dig out the manual and see if this would be
a "kludge" or not, stay tuned.
