Dinner conversation the other evening.
Dad: "Suzie, what did you do in school today?"
"Science class was pretty cool today. We have been teaching our robot,
Robbie, to move through a maze.last week my group was the first to make it
through the maze without hitting the sides. So today, Ms. Smith allowed us
to send the commands we made up to move Robbie through the maze up to the
International Space Station and back down to Robbie. We used ham radio to
do it. I got to push the computer key that actually send the commands!
There was some raspy sounds from the radio speaker, a delay, like a hundred
hours.well it seemed like a long time. and then Robbie started to go through
the maze!"
"Wow, that's pretty amazing."
"Yes it is. We listen for radio signals from the ISS all the time, but this
is the first time that we ever sent our own radio signal to the ISS from the
radio in our classroom. And I know that our radio waves were heard in space
because the signals came right back down to Robbie and we watched him move
through the maze.just like Mission Control does to make Curiosity move on
Mars."
Dad: "Well I didn't know you were an astronaut."
"Ah Dad, not yet, but I will be some day." ".I'm sure you will Suzie."
Interested how you can help your school do this? Ask me, mspencer@xxxx.xxx.

Norm,
The LNB units are used on the C Band Satellite TV Receiving Dishes ( the
ones that are 8 to 15 ' in diameter). The DRO is a ceramic piece glued to
the PCB with a metal case around it and a adjustment screw. Some are fixed
in a metal can. The Mixer is used for 3.7 to 4.2 GHz Y may be able move it
up to 5.8 GHz. The LNA may be able to go there as well. The ARRL and THE
RSGB have several books on making things in this band. A lot of surplus
equipment at sites is being changed out for new, and you might find
something that can be tuned down in frequency from the 6 GHz band.
Mini-circuits has several Low Noise amplifiers and mixers that can be used.
Suggest you check out their web site. Try to fine some Amateur Radio
Microwave Activity in your area. Most of us will spend time helping others
to "get on the air"
Good Luck,
Art, KC6UQH

Good luck with the project

Art,
How do I recognize the Dielectric Resonance Oscillator? Where might I
get one of these units? Where, how and with what do I plumb the rf
with?
Suggestion on parts re the lna ic and I assume a mixer ic?
Wonder about the limit of dead bug construction at GHz? What methods
might one use? I assume microstripline transmission lines..
No trips to AES, HRO or Skycraft here..

Hi All
Is it possible to use the D7G with UISS to track and map. Also it would be
fun to make some contacts. Off BB contact is fine

Brock,
Looks like page 53 in the manual has the pinouts to make up a cable, or
look here http://www.rpc-electronics.com/kenwood.php
I attached the manual for you in case you don't have it.
