Expert radio gear??
I recently bought a couple planes that were part of an estate sale. Although no radios could be found the planes are completely outfitted with Expert radio gear. I have never been exposed to this gear before but have been considering using it if it works and range checks. The RX's are FM and have crystals. I am wondering what TX's would be compatible with these systems?? Also how reliable were these RX's? Thanks for any info.
