The new AI assisted mode in #FreeDV, #RADEV1, is building a following in SE Aust. VK3TPM runs a net on #40m and this morning 8 stations participated. I used my #QMX (5W) to make my first ever contacts on FreeDV and worked local stations as well as hearing a VK5 and VK7. #amateurradio #digitalvoice

アマチュア無線で初めてのFreeDV交信は6mで東京都の局さんでした。
短波とか6mでこんなにもはっきり聞こえる変調はやっぱりびっくりですね。
少し嵌りそうです。

朝と夕方に海岸へ出向いて市民ラジオの運用を行いました。
北海道から東海まで開いていていつものペースで交信出来ました。
残り少ないスポラディックE層の季節を楽しみたいです。

アマチュア無線12m FreeDVでも関東局と交信出来ました。

昼からいつもの海岸へ出向いて、アマチュア無線移動運用でFreeDVモードを運用すべく、IC-705とノートPCの調整やテスト送受信等のセッティングを行いました。
自宅からはIC-7300Mで受信までやっていて10MHzで送信帯域が2kHz以下になるまで追い込みました。IC-705でも同じ手法を取ります。
FreeDVは非常に音質が良く4Gの携帯電話音声と遜色無いレベルですね。
初交信が楽しみです。
