I made a homemade usb to dmx using :
USB to TTL RS485 Serial Converter Adapter FTDI interface FT232RL Module

I did already order this little guy to see if that was the problem but it has not came in yet I think in comes tomorrow:
USB to DMX Interface Adapter LED DMX512 Computer PC Stage Lighting Dimmer R8H4

http://www.ebay.com/itm/LED-DMX512-USB- ... 1826235031

I do not have any problem with my homemade one using dmx cable. works right as it should with no dirty signal

I'd say the wireless transmitters do not like what's being sent to them.

Can you:
- Try with freestyler on windows ?
- Try with QLC+ on linux ?

You don't need to program the whole show in freestyler. Just a quick tet whther the lights flicker.

ok ill try it out thank you .
whats the rate the signal is sent at its like 30hz transmit rate on the output side or something like that I don't have it in front of me so I know im not saying it right, but does that have anything to do with it and can that be changed?

Symptoms are as if wireless transmitter slows FTDI serial output,
which gets updated by USB before DMX frame has completed.
If possible, reducing channels is better than reducing frequency.
I suppose that your FTDI interface is recognized by QLC+ like USB Enttec Open.
Here are QLC+ DMX USB Enttec Open tuning parameters:

FWIW, I forget to look for QLC+'s User Documentation hyperlink on the right side of the main page
instead of at the top..
