Well said, Rick.
Amen !

...and then there were the receivers and transmitters that we home-brewed
ourselves, which didn't have any frequency readout on them at all. We had
to depend on the frequency printed on a crystal to have an idea of about
where we were. I guess it was usually within a "kc" or 2 of what was
printed on the front plate of the crystal.
The term Hertz was introduced in 1960 but for the first 5 to 10 years,
people were still using "kc's" on the bands.
One of my favorite receivers was an old military surplus National HRO (like)
which was the NC-100 series, with that huge knob with even bigger skirts,
but with a readout of 0 to several hundred. Mine had sliding coils inside,
rather than plug in modules. I don't recall how many ranges it had, perhaps
5 or 6. I believe mine was an NC-101X; can't recall for sure. The only
readout was in meaningless numbers. Again the xtal controlled TX helped to
locate the frequency. Despite that, it was one of the most fun receivers I
ever had. That was in 1963.
Back then we were worried about things like cw tone, chirp, and drift.
Accuracy was not even considered. We didn't even have frequency counters.
If you were lucky, you had a surplus BC-221 frequency meter, of course we
had no way of knowing how accurate it was calculated.
Now that all of those problems have gone away, there is not much left to
gripe about, is there?
So let's take Hz.
BUT WAIT . . .
What about stuff like:
..> Our transmitters are now the big challenge of reducing the problem with
QRM on the bands, not the receivers; yet nobody is doing anything about it.
..> Some matchbox OEMs are still selling matchboxes with Voltage Baluns in
them and calling them symmetrical matchboxes, which they are NOT.
..> Most Balun manufacturers are selling what they call a 4:1 Guanella
Current balun, wound on a single torroid and calling it a Balun, which it
definitely is NOT. It forces an unbalance all the time. Yet they are
selling loads of them, and some poor Joe Ham is buying this stuff.
..> Some matchbox OEMs are selling matchboxes with this single core 4:1
Guanella and calling it a symmetrical matchbox, which it definitely is not.
..> Several antenna companies are making antennas with some random length of
wire or aluminum and a "magnetic balun" and flogging it as a wonder all-band
antenna, and many Joe Hams are buying these in good faith...
I could go on.
Now compare the list above with the problem of being 30 Hz off frequency.
Talk about majoring in minors!
How about we all get focused on the broadband noise that all modern
transmitters these days generate, some less so, some more so, and some are
really culprits. Now that's a technical discussion that might someday lead
to improving our hobby!
