That's the Sony ICD MX-20 in the front pocket of my Bihn Bag where it records more effectively than a lapel mic. You can hear some of its segments in several episodes stored on podcasting.ie and compare the Binh Bag segments with those recorded with an external mic. For example, most of Underway in Ireland #37 is done with the MX-20 attached to an external mic but two segments are just the Bihn Bag mic. They occur at 40:10 (lady with cat) and at 45:32 (credits). The ICD MX-20 has an exceptional on-board microphone.
