Huh? / Crypto Transmission from KPH
« on: July 21, 2023, 0138 UTC »
Crypto Transmission from KPH

Background
The MRHS in cooperation with our good friends at the Cipher History Museum will send a coded message in 5-letter groups via the facilities of coast stations KPH on Saturday July 22, 2023 Pacific time. The message will be encrypted using the famous Enigma code machine and is an authentic message sent by a U-boat in the North Atlantic in 1942.

Shortwave Broadcast / Re: CHU 3330 AM 1212 UTC 20 JUL 2023
« on: July 20, 2023, 1849 UTC »
In addition, the digital time code from CHU is comparatively simple to decode. That "screeching" sound that you hear between the 31st and 39th seconds past the minute is nothing more than a Bell 103 compatible 300 baud modem formatted FSK signal.

You can decode the CHU digital time code using a KiwiSDR. Select the FSK mode from the Extension pull-down menu then select one of the CHU frequencies under the Ham/Utility pull-down menu.

Hi Kris,

Quote
Important for me is the active operation of the Noise Blanker Wideband DSP, placed on the Home ribbon. Threshould deep cut introduces audio distortion - do it gently.

SDRuno has the same effect when the Noise Blanker level is set too deep. I find that the DSP also destroy some of the digital modes as it thinks it is noise. It is a compromise but the feature does work very well for me. You just need to know when to turn it on or off.
