I look forward to DXing with my PL-310 this spring using the Moxon antenna I recently built. The receiver's selectivity is simply amazing. I also have a PL-380 and it's almost equal to the 310. The only noticeable difference is the 310 has an antenna input and slightly larger speaker. Both are excellent receivers for ULR FM DXing
Good DX all.
