Dear JB,

I will give you some suitable answer concerning some of the mentioned
parts for free, due to the ham spirit ;-)

Part #1: Skyworks 2Gc PIN attenuator.
Part #2: ALPS VXCO (Freq. ?)
Part #3: Delta XCO 19.44Mc
Part #4: Corning VXCO 52Mc
Part #5: probably SAW filter from Temex
Part #6-8: are Filters

In general I know what these parts are, but would like to find some
data sheet when using them in later prrojects as i get not just one
but a big amount of them.

All but the last appear to be oscillators modules. Part #3 is a 19.44

All I can tell you beyond that is Google, Google, Google. I could tell
you
more by the end of the day for $200.

In the past when working on a synthesized data receiver module with a dead
Ref Osc, I spent several hours tracking down such data from various websites
in order to find a suitable replacement. Fortunately I had a customer to
pay for the time spent because going off the clock would have meant a loss
of earnings (and reduced tax contribution). Unfortunately, the company I
was contracted with retained the information (or not) and I was unable to
because of contract agreements.

The unit was mission critical in the automation of transportation and
handling of Mega-Tons of grain for import and export of food staples on a
massive scale and time was of the essence or the unit probably would have
been scrapped.

I have long noted the value of Ham Radio for dealing with many natural and
man made disasters, but the impact of economic disasters seems to have been
completely ignored and underestimated. Capitalism has forged a monetary
system as a common means of exchange between parties with different skill
sets and even of different and widely separated areas and locations.
Without a common and mutually beneficial monetary system, we would not have
gotten beyond the most basic of trade, instead relying on the
hunter-gatherer model even for our water. Those who were able to grow food
from their location could not trade very far away because of spoilage, and
because it would take them away from tending the farm. Communism must
resort to extreme intimidation in order to co-exist with GREED - a common
human frailty throughout the World. Indeed, greed is so universal, that it
inevitably becomes one of the ultimate motivations in any power struggle.
Indeed the naive concept of Communism is impossible because it isn't
sustainable, instead morphing into a form of authoritarian exploitation of
the productive members of society as a robber class sharpens its skills at
deriving support from the productive class, inevitably resulting in slavery
of the productive.

An agreed upon world-wide and secure system of exchange is vital to any
system of sharing goods, resources, expertise and knowledge. The
collective threats against such a system tends to limit our ability to
sustain a widespread and far-flung high standard of living. Although it
doesn't guarantee that greed won't have a negative impact, we need to
realize that greed isn't something that any system has been able rule out.

So Sir, in the spirit of Ham Radio, do it yourself and enjoy the thrill of
your own accomplishment and self-reliance.

My reply to the above would be just :
1)Amen
2) Long live the 'real' spirit of Ham Radio
