[TenTec] recording devise for Omni 6+

[Sam Bridges]

Hello Guys:
    Surely someone has already done this. I have an Omni 6+ and the audio out jack on the back is 1 mw at 600 ohms. I am looking for a device to record cw from this jack. I prefer a cassette recorder but what I have found that could work(?) is in the $100 range. I am hoping for something cheaper. The cheap one have no audio input jack or only USB or a built-in mic. Any one have experience with this problem please send me a line or two off list: kj4zm at arrl.net
