Hello Bill,

Hello Joerg, nice to meet you for the first time.


Likewise. You name sounds very familiar, IIRC from a book about design
of HF gear. Didn't you work at Collins in the good old days when they
had mechanical filters in their gear?

Regards, Joerg

Yes. I started at Collins Radio engineering department in 1964 and retired
from Rockwell Collins in 1990. For more info search Google for my name and
my call sign. See QRZ.COM for W0IYH. See www.noblepub.com.

Did you ever work on their microwave receiver designs?

Hello, Mike,

I had a little experience with some military L-band RF design (JTIDS), but
that is about all. I have also designed miniature lumped-element filters
for the 3 GHz region. But most of my work and also my ham radio experience
have been at HF. Also, I am mostly, but not entirely, an analog specialist,
which has put me somewhat into the Jurassic Age.

Not really. Newly minted engineers know remarkably little about analog
techniques. Yet at the beginning and the end of circuits stuff usually
needs to connect to the analog world. So don't be surprised when someone
begs you to do just one more stint when you are past 90.

Then again a SW engineer once told me that nothing is truly analog.
There is always that smallest digital step, the quantum.

So, digital is base two, and analog is base 1.6 x 10^19? ;-)

Not really. Analog's bits are just smaller. ;-)

Still, the digital guys kept telling us "Some day we'll get there and
then you are going to be extinct". I am not worried at all...

There is no reason to apologize for being good with analog. ;-) I
worked as a broadcast engineer during the time they announced the first
memory chip, (1101) which was a slow, noisy 256 bit * 1 DRAM with very
critical timing. I also did analog and digital work on the microwave
equipment built at Microdyne, before L3-Com closed the Ocala plant.

The reason I asked about the microwave equipment, I would like to
meet the people who designed the C-band CATV receivers I had to maintain
in the '80s. I always loved Collins equipment, till I ran into those
radios. They had a horrible failure rate, and took over six months to
have serviced by Collins. I think I still have a set of manuals for
the fixed tuned, and the agile models. I started repairing them for
United Video in 1982, and could return most of them to service the same
day.
