I also have some iMic units which work well on RTTY and while they have stereo Line In, but they do not have duplex audio that Iain is looking for. Ed - W0YK > On 3/8/2012 10:26 PM, wb6r...@mac.com wrote: > > Hi Jim - I've been using a Griffin iMic for years. Reliable. > > Inexpensive. FYI.

Griffin iMIC is a standard "USB Audio Class" device. Most modern operating systems support USB Audio Class devices with standard drivers. The iMic is reasonably well built for a commodity device. Nothing special positive or negative ... 73, ... Joe, W4TV On 3/9/2012 6:13 PM, Tom Azlin N4

in the last few days I've been evaluating a couple of low cost audio to USB interfaces for use primarily with digital modes -- RTTY, PSK, JT65, FSK441. My primary objective is to improve decode performance at low signal levels. I studied the catalogs and chose two low cost units that looked lik
