I think I've found a work around for this problem. I own 4 Calumet Litelinks (actually made by bowens. I'm using the triggers on Vivitar 285hv's. They work fine on Full power and 1/2 power but double flash on 1/4 and 1/16th power. Triggering the test on the flash unit gave no double, but testing from the transmitter = doubleflash.
I read on a post somewhere that I guy took the sync cord and wrapped it around a brass lite stand end and he didn't get the double flash. I tried it and it didn't work for me, but it got me thinking. He basically created a coil to "shield" interference. What I did was connect the spare synce cord male plug end to the sync-in jack. Then I wrapped it around a pc sync. The pc sync cord is then plugged in the pc socket on the litelink and the other end goes to the flash. The end of the coiled sync cord was not connected to anything. After getting all the cords wrapped I tested my theory out and wa la!! It worked!!!! I get a single pop on all settings of the flashes. Tested in the next room still with no problems.
So I guess the bottom line is the sync cable is not shield enough to prevent radio interference. Wrap the cord and all should be well. I hope this help to all having the same issue with the Litelink or Pulsar.
