IC-7760 HDSDR operations
D. Using HDSDR with CW Skimmer (For a wide bandwidth*)
The CW Skimmer application decodes the CW signals received from HDSDR.
Use this when checking the wide band and getting information of many CW stations. This is useful when you
participate in a CW contest.
L The HDSDR's local oscillator frequency (LO) is synchronized with the IC-7760's operating frequency.
L Manually set the same frequency to the HDSDR Tune frequency and the CW Skimmer LO frequency.
Install CW Skimmer (Shareware), VB-Audio Hi-Fi Cable (Donationware), and N1MM Logger+ (Freeware).
