C2001 Video Transmitter Frequency & Wiring Connections?

[RocKiteman]

Hello, all. This is my first post on this forum.

I am interested in using the C2001 video transmitter for "Kite Aerial Photography", to transmit video from a Canon PowerShot A570 IS digital camera I use. {The camera has an A/V receptacle, although I only need the video, not the audio.} I already have a separate SWANN miniature video camera/transmitter attached to my KAP 'rig' for aiming the thing by radio control from the ground. However, seeing the actual 'image' from the Canon digital camera itself would let me know EXACTLY what the camera is photographing {or videoing}. I can also {now} operate the camera's zoom by remote control, so seeing 'through' the camera would allow me to control that directly, instead of just 'guessing' at it.


The webpages for both this transmitter, and the lower-power version C2000, say they both transmit on CABLE channel 59. I have two small battery-powered B&W {crt} televisions that I would like to use with this, but I was not sure that they would receive 'cable' channel 59. I posted this question on another 'electronic' forum and was advised that they would work.

Has anyone here used either of these transmitters? If so, *what* do you use to receive the transmission from it?

Also as I mentioned above, my digital camera has an A/V socket for connecting to a TV. Instead of 'wiring' a miniature video camera to the C2001 transmitter, I would like to connect a 'plug' to hook-up to my digital camera. Has anyone tried that, or know anything about doing something like that?

Thanks in advance for any advice anyone can give me, and have a GREAT weekend.

Mr Rockiteman I was bored so I checked out Ramsey's PDF howto on the vid transmitter and from their instructions, there are "wires" involved. http://www.ramseyelectronics.com/dow...uals/C2000.pdf

The CCTV set up would need 12v, correct? or you're using your Canon--ok. Then from diagram on Ramsey, the "Cube" vid xmitter needs wired FROM camera, AND Cube needs the 9v battery pack. That's a lot of weight. In regards to CATV channel 59, I know it sounds odd, but you *will* receive what the xmitter is putting out over the air yet you must have TV set to "CATV" channel 59, as opposed to OTA channel 59. I am not an engineer, maybe someone would like to explain how this works?

So, we need A)camera that can be wired to the video transmitter. Transmitter needs 9v battery. Then it xmits over the air, and YOU pick it up via channel 59, but set the TV to CATV and not over the air channels. I apologize for replying since I have not yet tested this as you request, but I *know* it will work. Whether your kite (must be amazing!) can carry all of these accoutrements I do not know. I think what you are asking is, how can it be picked up on "cable channel" when you will be using a TV not hooked up to CATV, is that right? Yes, this is how it works. I've seen it being used, via LPTV on a different channel. Weird, but that's how it works. For kicks sometimes I do a scan on my set using OTA antenna but searching under CATV for some of these catches. I have yet to find one, however!

I actually built 3 tv transmitters last few weeks. First one was a one transistor model that actually made a beautiful picture, transmits through walls and floors, open air at least a hundred feet, but is very unstable, moving a vidoe cable, etc., causes static or to totally stop working.

Next I built the Ramsey TV-6c Kit. Even though I made a couple “goofs” during assembly, (I fixed them quick…distracted by phone call…), it works great, even on the new digital/ analog tv sets…just not as pretty as the old style tv sets. When I solder, I always use heat sinks on transistors, diodes and sometimes capacitors, etc. Sometimes just moving the power supply cord, or video cord can drastically improve the quality of the picture, especially the new finicky digital/ analog television type sets. My voltage regulator and RF Power transistor quickly heat up to with-in limits…150 degrees or so…so I added heat sinks…seems to have helped the slight ripples in the otherwise great picture.

I then designed and built my own version of the Ramsey TV-6c …last couple days. I actually built my own L4: tuning coil, and L1: 4.5 Mhz audio/video mixer, using a soda straw and 3/4″ pvc pipe. Actually works, but the Q-5 transistor quickly overheats, and shuts down…My first attempt at ‘making’ my own components. Many times I build a kit and build my own from scratch...just to compare and have fun and learn..

I accidentally posted this comment on the wrong Thread. Should have been on the TV6C Thread. I've contacted the Administrator to remove this. My apologies.

LightSward, that is okay. You actually might have done me a favor by doing that.

Did you get 'plans' for your "transistor model" transmitter from a book? I have a book @ home with plans for two separate video transmitters - one with video & audio, & one with video only - & I wanted to know if that was where you got your 'plans' from.

Thanks in advance.

PS Kristinmak & LightSward: I am composing this on my notsosmartphone. My desktop PC is currently out-of-commission, & my laptop PC is 'stowed away'. When I get to a working PC, I'll reply to your other comments.

I chuckled at your "goofs" comment. Only because I have done it so many times. My wife actually has nicknamed me Tim The Toolman Taylor haha. I always get it working in the end though. You've just got to tinker until it's just right.
