Normally, I defer to your expertise. However, my experience is that the SignaLink is no better or no worse than the built-in sound card in my Lenovo T400 laptop.

Likewise, after your glowing recommendation of the US100, I bought one. I saw no difference with it either. It appears to me that the RTTY SNR is set at the K3 Line Out and a lower noise/higher dynamic range sound card is unnecessary. If I'm wrong (always a distinct possibility) I would like to know how. I "retired" the SignaLink mainly because I was out of USB ports on the laptop.

What is "my audio stuff" that you are currently using? If it's to/from an internal sound card, it's probably worth replacing with a decent USB audio interface. FWIW, the SignalLink box is highly overrated, thanks to advertising by those who sell it. And "help" info on the DX Engineering website to solve RFI issues strongly suggest that it has a Pin One Problem.

There are several USB audio interfaces sold mostly to DJs and home studios that work very well for us. Several years ago, I bought and tested thoroughly two low cost units that work VERY well -- much better decoding of digital signals, especially weak ones. The simple Numark stereo interface costs about $35, the now discontinued Tascam US100 was $75, and was replaced by a US120 that costs more. They work equally well, and neither has a Pin One Problem.
