I have two K3s, one has the new DSP board, so I hooked them up together and listened to low frequency tones. The higher SN radio definitely has more bass. In fact I have noted a few times, just how low it goes. It seemed very unusual for a communications radio to do that. So I listened to the

Hi, Bill! If you send the W2 a P via the W2 Utility (or the buttons on the W2 Interface program) the Peak-Hold LED should come back. Sending the command toggles the feature on/off with each P. 73, Brian, W6FVI Elecraft, Inc. Bill K9YEQ wrote: Bert, I had the same issue. I think when I

Hi Dave, You are out of luck below 490 kHz. Also, you need the general coverage board so that you can tune below 1.8 MHz. There is a bandpass filter that rolls off on the normal antenna jack, (for BCB protection) but you can use the aux antenna jack on the KIO3 strip and get great

Turning the sub RX on and off is cycling a whole lot of things. SO2x operation in common practice uses something external to rig(s) to switch/blend audio. Wayne has something on the list about improving SO2x operation, but you can bet it's not a cheap fix. I think there also was a reflector
