Can one radio trigger fire two speedlights in the same softbox?

I have a pair of Yongnuo RF-603 radio transceivers, two Nikon SB-600 flashes, and a Nikon D200. I’d like to put both speedlights inside one large softbox for more output. Can a single receiver trigger both flashes from its hot shoe or sync port, for example with a splitter cable or another DIY method? I know I could use Nikon CLS from the D200, but that can be unreliable outdoors, at longer distances, with long lenses, or when the flashes are hidden inside the softbox.

Another option to consider is getting one pair of radio triggers and then using an optical device like the Wein Peanut to make the second flash into a slave, if it doesn't already have that capability. I've used this kind of setup to fire extra flashes and stretch my existing wireless trigger capability.
Note that if you go with the wired trigger bridged off a single wireless device that the trigger voltage for the two flashes should be the same to avoid any problems with the flash units. Since you mention that you're using two flashes of the same type you're covered.

Yes. A single radio trigger can fire two flashes if you split the receiver’s sync connection to both units, or if the second flash is triggered optically from the first.
Common options:
- Use a Y-split sync cable from the receiver to both flashes.
- Use a dual-shoe TTL/sync cord so both flashes connect to one receiver.
- Put a second receiver on the same channel; many radio systems let one transmitter fire multiple receivers.
- Use an optical slave on the second flash if line-of-sight inside the softbox is workable.
If you hard-wire two flashes to one trigger, it’s safest when both flashes have the same trigger voltage; with two identical SB-600s, that concern is minimized.
For a softbox, a short dual-shoe cord or Y-split sync lead is often the simplest approach, while a second receiver on the same channel gives the most flexibility.
