Status: offline 		Hey Everyone,

I'm a new guy here. After reading many posts re: aerial photography, I have purchased a 1500mW system from spylinker through EBay. ($124.00 inc. S&H) It includes Camera, Tx, Rx power supplies and cables. Unable to tell what kind of camera it is, it is described as free gift in the ad. It is a 1.2 GhZ system. I plan to mount it in my Sig Kadet Sr just as "Fubar One" has (love those vids on your site.

Sure would like to know how you mounted the camera on the servo to get 180 degree direction. I have a JR xp662 6 channel radio and only have retract and gear channels open. Any help here would be appreciated.

I'll keep everyone posted on the progress of this project and on the performance of the system.

Also wanted to recognize the nice work of "Rucanunes" and others that I've seen on this board.

Not a place you want to draw attention from, post 9/11

Thanks for the tip "closetflyer". I had no idea. I live in a very rural area of northern WI. Our field is 10 miles away from a grass landing strip on a golf course, the next closest airport is 50 miles away.

Can anyone tell me which frequencies require licensing or are restricted. I am not going to pursue a HAM license for the 30-40 minutes a month that I expect to use the system. I am considering a 2.4 Ghz system with a ccd camera as an upgrade.

Got some new for you.
If you are using a 1.2 GHz tx for video in the US., the FCC can give you a fine for more than $10,000 and a 3 year jail term......
Thank Im joking.....
A few months ago a guy was using one out near Dobbins air force base, the air force traced the signal to him:
took him and his equipment and confiscated his video stuff.
The FCC was called in and now he is facing charges.

If you are looking for good range and for clear video use a good 1 watt transmitter ( do not exceed 1 watt of power...) at 2.4 GHz and a high gain
low nose amp on the receiver,.
This type of setup is completely legal and you wont get into any trouble.

P.S.
The fcc can see you on the 1.2 GHz range, because the military uses it and is very unforgiving to people they find on it.
They are not in the mood to play games..... :

My father converted one using this info also with great results.
I used the pan&tilt setup from Servo City which is basically a plexiglass plate with a large Hitec compatible servo arm. The plate screws down on the servo arm. I used that super plastic type velcro to hold my camera to the plate. The servo is mounted in the wing just like an aileron servo. I added 1/4" balsa sheeting with a lite ply doubler between the ribs of the first wing bay under the wing.
Such as:
Camera Servo!
This servo is slaved to channel 7 and a variable switch on my 9C but you really dont need 180 degrees for a wing mounted camera. I have tested it with the gear switch and it works fine. 180 degrees would show you either mostly the front of the plane or mostly the rear if mounted near the fuse such as the way mine is.

So hundreds of people buying these from e-bay are breaking the law? All of you guys in here are talking about doing illegal stuff?

Dan and Mike
Soldering servos not for me though. I have all JR stuff anyway.

...........and a note to Steve..........
I heard it was a garage door-opener that brought down the shuttle. My C-band sattelite dish receives channels from 1.13GHz through 1.25GHz. So will I be able to pick up my aerial shots on my TV?

Thanks again fellas

Status: offline 		I actually took a frequency meter to the 1500mW Spylinker rig and found it to transmit at a frequency within airport radar (at least here in canada).

So I can't imagine it would be too fun having the spooks from the CRTC (Canada's FCC equiv I believe) and Transport Canada on your ass at the same time.

The field I am planning to fly at in Toronto lies right underneath Pearson Airport's airtraffic pattern. So I pretty much tossed the piece of junk in the garbage.

The new spylinker system seems to have some dipswitches on the Tx so you may be able to fiddle with it so that it will transmit in a legal range.

You are correct about the switches.( all my Tx's have them)

I will check the frequencies and report back.
I hope this solves the "legal" issues associated with the 1.2ghz systems.

Best regards,
Vova Reznik

Here is bandplan published by FCC (small portion listed here)
960.000 - 1215.000 Aviation Service NAVAID/DME
960.000 - 1350.000 Land-based Aero NAV
1240.000 - 1300.000 Amateur 23 Centimeters
1350.000 - 1400.000 DoD

Congratulations Vova, you have solved "legal" issue with 1.2ghz equipment... it is ILLEGAL.
