As I use my IC-9700 for 2 m and 70 cm only from home, I connected a dummy load to the 23 cm antenna socket. Next was to tune it to 1,296.174 MHz (of course) and to call in FT8.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"288\" src=\"https:\/\/dj5ar.de\/wp-content\/uploads\/2020\/09\/2020-09-25-21_24_39-FT8-23-cm-1024x288.png\" alt=\"\" class=\"wp-image-3625\" srcset=\"https:\/\/dj5ar.de\/wp-content\/uploads\/2020\/09\/2020-09-25-21_24_39-FT8-23-cm-1024x288.png 1024w, https:\/\/dj5ar.de\/wp-content\/uploads\/2020\/09\/2020-09-25-21_24_39-FT8-23-cm-300x84.png 300w, https:\/\/dj5ar.de\/wp-content\/uploads\/2020\/09\/2020-09-25-21_24_39-FT8-23-cm-768x216.png 768w, https:\/\/dj5ar.de\/wp-content\/uploads\/2020\/09\/2020-09-25-21_24_39-FT8-23-cm-624x176.png 624w, https:\/\/dj5ar.de\/wp-content\/uploads\/2020\/09\/2020-09-25-21_24_39-FT8-23-cm.png 1477w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The result in brief: No problem to decode with my regular 23 cm rig (OCXO controlled). Just a moderate drift and the signal appeared about 100 Hz too low. Nothing to worry about.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But never the less, I prefer JT9f on 23 cm, as FT8 is useless on aircraft scatter.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>September 25th, 2020 A question in a Facebook group about a GPDSO for an IC-9700 to be used on 23 cm for FT8 inspired me for a quick test.
