Nope, that's not my point. My point was that it is almost expected that
hams will open their radios and look around and such. Cameras are not.

Yeah, but when you open a radio things generally don't fall out and
cause problems when trying to get replaced.

Lets see, my Drake twins came with service info. When we entered the
new equipment era, with mostly transistors and ICs, service manuals were
extra cost options. I have owned Drake twins, Icom 721A, Icom 735,
Yaesu FT-840, Icom IC-27H, IC-2400A, IC-2410, IC-2340, Yaesu FT-5200,
Alinco DR-610T, and various handhelds. With everything after the Drake
stuff the schematics that were included with the radios would not be
enough to fix the radios. Thats why they sell service manuals.
It is sort of a shame that knowing how to pick out a radio rather than
build it is the way our hobby has progressed. But on the other hand the
hobby equipment we use has kept up with technology. I remember the old
SSB adapters for the Collins R-390 series. They were as big as the
R-390s! To most manufacturers our equipment is not the bread and butter
of their business. Commercial radios are big users of modern technology
and it just sort of naturally follows that the ham gear is the same. So
to bring out new ham gear they use the technology and experience they
gain from their commercial endeavors. Not nice to a purist, but
something that is really good for the users.

Well with the new electronics in cars, I leave everything to the
dealer. I'm not loaded so I let them do what they can do better than
what I can do. My T-birds have electronically controlled automatics. I
don't know which is the problem, the electronics or the stuff inside the
tranny. I can't afford to buy a computer and find out a valve body is
messed up.....

Well, this goes back to following the list. Those of us that have
followed the list for a while appreciate John Hermanson and understand
that when he says don't go there he means don't do that because it is
not in your best interest. An example is that the rubber focussing grip
on someone's lens came loose. The lens owner was going to use super
glue to keep it tight. John explained why he didn't want to do that.
He could have kept quiet then repaired the "fix" sometime in the
future.
Its not that one should not disagree with someone dispensing free
advice. It's more like, again I have to say this, those of us that have
been reading the list for a while respect John and his advice.
If Pete The Picturetaker gave you the advice that John did this thread
would not have gone the way it did since Pete isn't John.....

I forgot what kind of OM you're having problems with, but my pair of
OM-1s and my OM-2 have screw down hot shoes..... They are not
permanently affixed to the bodies...
73, Bob
