AD9850 DDS VFO Premixed Version 1.1a

AD9850 DDS VFOのプリミックス用として9/6に公開したものの、Version UPである。10/27公開したProgramは、受信部にシングルスーパーを使うことを前提にしたものである。今回のVersionは、10/27版より機能が低い。変更内容は、STEP 100k追加とメモリーチャンネル2ch追加である。メモリーチャンネル多チャンネル追加を狙ったが、BASCOM DEMO版(4kb)の制限で、2chが限度であった。2chのメモリーでも、無いより使い勝手向上する筈だ。メインチャンネル(ch0)のみ、他のチャンネル(ch1,ch2)に移ってもRITを保持する事など、10/27版と同じ仕様。Software識別のため、Ver1.1a。
