[Elecraft] K3 and 48,000 Hz Digital Issue

[Robert Nobis]

Hi James,

I use a TASCAM US-366 with my Mac and have the sample are set to 48,000 Hz with no issues running WSJT-X versions 1.4 and 1.5. I use VOX control. You might have to go in and week the K3 VOX Gain and Line In Gain menu settings, however. 

73,

I'm running on an iMac, OS X 10.10.4, an Elecraft K3, and my sound card is a Tascam US-125M. I am able to use the K3 and the new version of the software but have an issue with the documentation procedure….

I have been using the above configuration at 41000Hz with no problems. When I try running at 48000 Hz, the radio does not go into transmit mode. If I switch it back to 44100 Hz, it works OK. The specs for the US-125M indicate that it should work up to 48000 Hz. When set to 48000 Hz, I’m able to get the usual decodes, but can’t transmit. I’ve got it set for the K3/KX3, and CAT control.
