I'd like to know if anyone knows what a v j expander 5 is? It's installed on the back of a Robyn 123 b. I'm fairly sure it adds more than the 23 channels to the 123b. Which is a stock 23 channel radio. Does anyone know what this item is exactly? Thanks
 

Never heard of a VJ Expander 5 but I would imagine that it adds extra channels. Back in the old 23 channel pre-PLL days it was common to add an external box that had a rotary switch that could select different crystals that would provide additional frequencies.

Get ahold of a frequency counter and a dummy load and just start stepping through the different positions and see what you come up with.
