RadioPopper PX Transmitter Overview

The RadioPopper PX-T Transmitter maintains the ETTL/iTTL functions of your camera and flash while adding radio triggering that can fire your flash at distances of up to 1,750' depending on the prevailing conditions.

The transmitter, which comes loaded with both Canon and Nikon software, mounts to your master flash or commander and allows slave flash units equipped with an optional PX Receiver to receive TTL or iTTL signals by radio without the limitation of having to be in line of sight with each other. Put simply, the RadioPopper enhances your ETTL/iTTL system by allowing it to act like a radio slave setup.

The 16-channel PX-T Transmitter has an auto-search feature that seeks out the cleanest channel for use at your specific location. Several flash units can added to up to 3 groups that can be controlled and fired simultaneously or group by group. There are no wires or shoe mounts on the unit, instead the transmitter is touch-fastened to the top of your master flash. Alternatively, with Nikon cameras with pop-up commander flashes, you can mount the transmitter to a special pop-up adapter that allows unimpeded use of the integrated flash.

While DSLRs can use up to 1/250 second sync speed, the PX system also supports high-speed sync speeds up to 1/8000 sec. The PX Transmitter gets approximately 25 hours of power-on time from the two included AAA batteries. It requires use of an optional PX Receiver for normal operation.

    Awesome Transmitter for the SU-800

    By Drew Brashler
    Rated 5 out of 5
    Date: 2015-09-10

    I use the PX Transmitter to trigger my JrX and JR2 receivers. I place this on top of my Nikon SU-800 to give me AF-Assist during receptions and the ability to trigger the flashes. I use a JR2 transmitter to make flash level adjustments and do NOT use the PX transmitter for level adjustments. The PX-T will trigger all three groups of the JrX and the all four groups with the JR2.

    Great!

    Works just as advertised. Only negative is the bracket that slides onto the camera's hotshoe doesn't lock in place so it's only a matter of time until the transmitter slides off and falls to the ground.

    question

    question

    If I understand how these work, they just interpret the optical slave information into radio frequency, send the info to the receiver which then interprets it back into optical info. If that's the case, can this be used with Sony?
    Asked by: Anonymous
    Unless there is a firmware update for Sony, no they will not work. It not only fires the flash, it a full ttl system. You can control power of your speedlights from camera. Every camera manufacturer has different communication protocols. If they don't sell it as Sony compatible is because they are not.

    question

    Does this work with the nikon sb5000?
    Asked by: Anonymous
    Funny you should ask. My son and I just tested this the other day on my sb5000. What we found out is the controller does work, but the receiver has to be rigged into the right spot on the sb500, since the sensor is way higher than on the SB 910s, etc. Once it is rigged into right spot, it works perfectly. I figure radio popper will come out with the correct size adapter. Meanwhile, we will just rig up our own.
