I have just started dabbling with the digital mode, PSK31. I am using my Yaesu FT-450, 50 watts, a Signalink Integrated Sound card device. I am using a Toshiba laptop with Windows 7. I am using the Digipan program. More info can be found on my PSK31 page.
BHI Noise eliminating speaker.
The NES10-2 MK3 Noise Eliminating Speaker removes unwanted background noise, hiss, hash, QRM, QRN, computer hash, plasma TV interference, white noise etc from speech, so that you can hear more clearly and listen stress free. It works on all radio bands and is suitable for shortwave listening and for use in commercial radio base stations.
The NES102-MK3 has a rotary filter control knob on the rear of the speaker that replaces the DIP switches that were on the MKII speaker, making it easier to change the filter level whilst using the speaker.
