It was a bit of a journey, so I thought I would add it to my blog for later use.<\/p>\n\n\n\n<h2><strong>Rig control:   <\/strong><\/h2>\n\n\n\n<p>The G90 CAT interface is a little non-standard (If you can call any rig interface standard).  My original advice to use the IC7000 emulation is clearly incorrect, as it didn&#8217;t operate with the JT8Call software.<\/p>\n\n\n\n<p>The solution I found was to use flrig as a software mediator between JT8Call and the radio.  I downloaded flrig from sourceforge at this URL: <a href=\"https:\/\/sourceforge.net\/projects\/fldigi\/files\/\">https:\/\/sourceforge.net\/projects\/fldigi\/files\/<\/a>  and installed it.     Then I configured my radio as a IC-746PRO, using 19200 baud as the speed.  I was careful to configure flrig to use PTT via CAT to allow transmit to operate.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"878\" height=\"533\" src=\"http:\/\/www.vk1zdj.net\/wp-content\/uploads\/2019\/12\/flrig_config.jpg\" alt=\"\" class=\"wp-image-200\" srcset=\"http:\/\/www.vk1zdj.net\/wp-content\/uploads\/2019\/12\/flrig_config.jpg 878w, http:\/\/www.vk1zdj.net\/wp-content\/uploads\/2019\/12\/flrig_config-300x182.jpg 300w, http:\/\/www.vk1zdj.net\/wp-content\/uploads\/2019\/12\/flrig_config-768x466.jpg 768w, http:\/\/www.vk1zdj.net\/wp-content\/uploads\/2019\/12\/flrig_config-80x49.jpg 80w\" sizes=\"(max-width: 878px) 100vw, 878px\" \/><\/figure>\n\n\n\n<p>I configured JT8Call to use FLRig as the interface and up it popped &#8211; Simple as that.  It&#8217;s amazing what a diference having a correctly configured control interface was.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"982\" height=\"632\" src=\"http:\/\/www.vk1zdj.net\/wp-content\/uploads\/2019\/12\/JS8Call.jpg\" alt=\"\" class=\"wp-image-202\" srcset=\"http:\/\/www.vk1zdj.net\/wp-content\/uploads\/2019\/12\/JS8Call.jpg 982w, http:\/\/www.vk1zdj.net\/wp-content\/uploads\/2019\/12\/JS8Call-300x193.jpg 300w, http:\/\/www.vk1zdj.net\/wp-content\/uploads\/2019\/12\/JS8Call-768x494.jpg 768w, http:\/\/www.vk1zdj.net\/wp-content\/uploads\/2019\/12\/JS8Call-80x51.jpg 80w\" sizes=\"(max-width: 982px) 100vw, 982px\" \/><\/figure>\n\n\n\n<h2>Audio Interfacing:<\/h2>\n\n\n\n<p>The next hurdle was to sort out audio interfacing for the audio side of the interface.  I used a Xiegu AUX port extender (CE-19) to break out the audio from the AUX port.  <\/p>\n\n\n\n<p>To connect the radio to the laptop, I used a 3 pin (Speaker, mic, Ground) to 4 pin cable ( Phones Left, Phones Right, Gnd, Mic) , connecting the audio.   The only thing I had to be careful of was to configure the G90 to use the AUX input as audio [Func, Pow, Pow] instead of the microphone input.<\/p>\n\n\n\n<p>Tonight (When the outside temperature here in Canberra, Australia drops below 36 degrees Celsius) I shall enjoy spending an evening catching JT8 Contacts on the 20m band while enjoying cheese and beer.<\/p>\n\n\n\n<p>What a wonderful Christmas this has been.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Today I worked on getting JT8 working with my G90.
