FAQ

1) Which system do I need?: It depends on how you shoot. If you are looking to maintain TTL and/or HSS, then you will be looking at our PX system. The PX system is designed to replicate all data that is present within communication between a master and slave flash in both Canon or Nikon systems. Therefore you continue to shoot the way you always have but without limitations of line-of-sight, distance, and other factors.
The JrX is another system we have available that is just as reliable as the PX system. However, it does not support TTL or HSS. Many people would classify the JrX as a "dumb trigger" but you will find a lot of extra features on the JrX that you won't find on your average run-of-the-mill "dumb trigger." The JrX Studio receiver has the capability to control power output on certain lighting systems. The JrX Studio Receiver can control the output of AlienBees, White Lighting and Zeus lighting systems. You may also pair the RPCube with the JrX Studio Receiver to control power output on TTL capable Canon or Nikon compatible speed lights.
2) What kind of range can I expect with RadioPopper components?: More than you need! We designed our systems to have ranges that exceed 1500ft so that you won't ever question if it will work at lesser distances.
3) Which countries do you currently sell product in?: United States, Canada, New Zealand, Australia, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Norway, Poland, Spain, Sweden, Switzerland, United Kingdom. More countries soon to come!
4) What kind of batteries are used in your product?: The PX system uses AAA batteries. The JrX system uses CR123A batteries.
5) Can I mix the PX system together with the JrX system?: Yes. Just remember that any time you mix the PX system and the JRX systems together, you will only have the capabilities of the JrX system. Example: If you are using a PX transmitter on a Canon 580EXII master flash and a JrX Studio receiver attached to a Canon 550EX off camera, you will not be able to utilize TTL or HSS.
Although you can use a JrX transmitter with a PX receiver (firmware version 6.06 or later) on Canon system, you cannot use this setup on Nikon systems.
6) How many available channels are there?: The PX and JrX systems have 16 available radio channels.
7) Why would I need an RPCube and which flashes can I use it on?: The RPCube is a component that works in conjunction with the JrX Studio Receiver. Using an RPCube with a JrX Studio Receiver allows you to control the power output on most Canon or Nikon compatible TTL capable flashes. Note: The RPCube will not work with the Nikon SB-900 or the Nikon SB-700.
8) Which flashes can be used as a master on Canon & Nikon? Which ones can be used as a slave/remote?: Canon Master: 550EX, 580EX, 580EXII
Nikon Master: SB700, SB800 & SB900

Canon Slave: 420EX, 430EX, 430EXII, 550EX, 580EX, 580EXII
Nikon Remote: SB600, SB700, SB800, SB900
9) Can I use the PX transmitter with my commander unit?: Yes, whether it is an external or internal commander, you can use the PX transmitter to communicate with it.
External Commanders:
Canon ST-E2
Nikon SU-800

Integrated Commanders:
Nikon D80, D90, D200, D300, D700

10) Can I shoot with the On-Camera Flash (Master) not contributing any light to the picture?

Yes, you can set your on-camera flash to be used as only a master/commander and not actually contribute any light to the photo. You may still see a flash being emitted from the on-camera flash but that is only used in communicating to the slave off-camera flashes and will not actually add to the exposure of your photo. Please consult the flash manual for details on how to do this.

11) How do I attach a Softbox to speedlight with a PX Receiver on it?

Many softboxes for speedlights are designed to fit a hotshoe mount. Therefore, to correctly attach those softboxes to a speedlite with an RP PX Receiver bracket, you will need a 3rd party adaptor that converts the 1/4" -20 on the bottom of the bracket to a hotshoe. The 1/4'-20 to hotshoe adapters are widely available online.
