[Elecraft] Apple MacBook Pro Audio for PSK-31 with K2?

[Paul Wilton]

Just about any old USB soundcard will work with a MacBook Pro - I use an old Creative USB Soundblaster that I picked up second hand.  Noting that you can plug in an iPhone headset, I did experiment using an iPod Classic 4 pin 3.5mm to 3 x phono connectors but decided it was too work to sort out since the "input" would be at microphone level and would need a capacitor to remove the microphone bias voltage.  Going with the USB soundcard was far easier.  You can pick up some no-brand "dongle" versions for less than $10 on ebay.
