Join HamSphere Facebook Digital Modes groups:
- For work digi modes on 30 meters on HamSphere 3.0 you should keep connected the button “CODOFF“. On HamSphere 4.0 you must use the Codec Selector to disengage the audio codecs and transmit undistorted/uncompressed audio over HamSphere (the bitstream in Codec OFF mode is about 150kbps compared to about 50kbps with codec.)
- you can use the VOX function on HamSphere 3.0 by pressing the “VOX” button and calibrating the function with the correct Gain and Delay on “Settings“, if you don´t want to use this function you must press the PTT to transmit.On HamSphere 4.0 version if you want to use the VOX function, press the “VOX” button and set the “VOX GAIN” button in a good level to operate.
- you can select the Stereo Mix in your sound card. (to learn how to do this you can take a look on this page by 43HS031 – Bruce)
- you must keep good ALC levels in your transmition to do not overmodulating.
- you can use one of the programs for digital modes that you can find here.

Weather Fax (HF – WeFax) mode on HamSphere
In October/November 2012 our friend Dwight 25HS138 in Tokio – Japan have been made on HamSphere 3.0 the first experimental transmissions in WeFax mode ICO288 240LPM on the 30 meters band of HamSphere using FLDIGI software. The transmissions were made on 10170 kHz usually at 12H00 UTC, with satellite images and several meteorological analysis charts from all continents.
