Clive, I have an Icom R75, and although some will diss this radio, I
can tell I enjoy the "bells and whistles" a great deal. The stability
and crispness of the signal (both driftwise and in terms of AGC and S-
AM) that can be achieved with this radio is quite nice.

Did you get the crystal oven on that one?

The S-AM on
this set is only so-so, from what I understand - I would love to hear
what the really good S-AM (on a more recent Drake, for example) sounds
like.

I've got sync on my Drakes, Lowe Ten-Tec and AOR. The difference
is in the distortion during fades. There's less of it. The fades are
still there, but the audio doesn't shatter.

If you know what you're listening for, it's a big difference. If
not, it's not that big a deal.

Oh, BTW - no crystal oven. I have never noticed a single stability
issue at all.

Good to know. Thanks.

Thanks, Peter - well, that's about what I thought - the Kiwa-modified
S-AM on the R75 definitely helps soften the blow of the fades (the
distortion disappears for all practical purposes), and the AGC when
the RF Gain is turned back a wee bit fills in and remedies all but the
deepest fades. I just figured the Drake/AOR/etc. did it better. Not
having ever heard one in person (NOBODY sells or demos them around
this metropolis), I just don't know for sure. In fact, you can't find
any shortwave receiver sales at all anymore except the usual lowball
Etons at RS. HRO has nothing but tranceivers anymore.

It doesn't sound as impressive as it looks. The audio is
comparable to Sat 700, which wasn't quite as smooth as Sat 500.

I think the "really good" sounds like the "so-so", only happens more often.

I can definitely tell when some station is ten or more kcs off where I'm tuned,

awhile, but usually move on, suggesting they sober up and quit leaning on the
VFO knob.

My receiver is stable to less than a twentieth of a cycle over several months.

I keep wondering how you'd measure such a thing. Leave it on for
several years to see if the oscillator drifts one hertz?

Not to be too precious, but that does not sound like the best use of

I worked with one engineer who built a frequency standard using
WWV as a reference. He would hook that up to the air monitor and
compare our carrier to the reference when he did a proof.

With a fairly simple scope you could see the smallest differences
between the two frequencies. He plotted drift over a month at a
time. And could extrapolate out months at a time with surprising
precision.

He showed me how it would be a fairly simple implementation to
use the WWV derived reference signal to control the local
oscillator's stability outright.

When we went to AM stereo, we had a serious issue with platform
motion near the nulls of our 6 tower array. He synced to WWV to
reduce that locally, and did a presentation to the state
broadcasters association describing how platform motion could be
eliminated entirely by syncing to WWV as a standard across the
implementation.

It's not difficult to do. Requires little expense, and can be
applied to every receiver in one's stable.

It's possible for Bob's receivers to be as stable as WWV by
simply using WWV as a controlling reference.

You can always find obstacles, if you look hard enough.

If you know what you're doing, whether capturing photons in the
environs, or sucking electrons out of the ether, you don't miss
anything. No matter what you're carrying.

I don't even carry a camera bag.

By way of comparison, I have to travel light. There simply isn't
room in the aircraft for what I can't hold in my hands. So, a
premium lens is essential. And the right selection of premium glass
is required. For most shooting, two bodies, two lenses. 24-70mm f2.8
on D700, and 70-200mm f2.8 on D300. Covers any territory I may
encounter.

It might drift more that a hertz over that extended time frame,
I'm too impatient to see.
Usually check it about every other month on a boring Sunday.

I don't dwell on stability to the point of obsession,
It's just one of many assets the radio has going for it.
And the hobby dollar cost, once made, is better justified
for the totality of features than any single one.
At least I'm not constantly pouring cash into the black hole of some other
hobbies. I used to be heavily into film photography g

That radio is the best SW portable I've ever had. Mine is the E1XM model
and I even got the antenna module, but don't subscribe and haven't used it since
the free OTA special a couple years ago (channel 130 POTUS 08). I even have a
Sirius capable radio that I decided not to get the antenna module for.

I really like satellite radio. I've had it in a couple of rental
cars, and it's da bomb. Gets a little goofy under heavy tree cover,
but the selection of quality music (classical, jazz) is wonderful. A
great replacement for general-listening FM broadcast.

Cameras, you say? I have a Lot of very old film cameras.A foot locker
full of them and another foot locker about half way full of them.Also, I
have some very old movie cameras and some old camera lenses and other
camera related thingys, some old tripods too.I bought them many years
ago at thrift stores and junk shops, bought them when the prices was
Good.I am and always have been a junk collector, all kinds of junk,
radios too, but it isn't all junk.Some old cameras are very collectible,
check out the Browns catalog about old collectible cameras.

I almost never take any pictures, but when I do, I use my Kodak FX 600
film camera.It works just fine for me.
