Hi folks,

I may be barking up the wrong tree here, but I have a problem which is
driving me mad.

I purchased these

for work. I'm sending an on stage camera through them, I've attached a couple of PP3 clips to the transmitter so
it can be strapped to the camera and allow the user to walk around with the camera and not trip over cables etc.
Max transmitting distance is 12 to 15 feet tops.

The problem I'm having is that the signal is garbage, it cuts in and out and there is static (interference?) al over the
screen. This doesn't change no matter if it's powered by mains or battery or if the whole rig is used in a different venue,
nor does it make a difference if I change the camera out for a different source.

The only way to make the picture better is by putting the aerials of the Tx and Rx within an inch of each other.
Obviously this won't do.

I know they're cheap and therefore you get what you pay for, but I would have expected them to work a little better than this.
I don't have a massive budget and had to fight just to get these. More expensive ones as a short term option are out of the
question, but will be on a future P/O!

I read somewhere the 2.4GHz range was the usual WiFi operating range so I thought about perhaps changing the oscillators
to put it on a different range of frequencies. Again, Obviously I'd check for a legal range etc.

My main question is, is there any way to circumvent the problem without changing the oscillators (crystals?)
and if not, will swapping these components work?

Thanks Folks!

 

Is there a WiFi transmitter operating nearby?
That could be causing interference.

 

Yeah, there are quite a few.

I think you're right, it's that that's causing the interference.
Do you know of a workaround?

Other than shutting off the WiFi transmitters, no.

 

I would suggest doing a frequency sweep of the work environment. Then put your video link on a quiet frequency.

I doubt that inexpensive device allows any frequency selection.

 

I'm sure your right. We need to find a quiet area before we purchase a device.
