UZ7HO局による SoundCard Modem が Ver 0.71b にアップデートしました。
改良点は以下を読んでも良くわかりません。事後生成される soundmodem.ini の
NRMonitorLines は約1000行にしたほうがよいと思います。上図は、144.660MHz_
APRS を受信しているところです。アンプなしで 静岡県東伊豆の信号もデコード
しています。南西方向は相模湾の海だけで障害物はないので受信は当然ですが。

SCM v0.71b changes:
- Fixed "Frame Collector" operation with MAXFRAME greater than 4 and IPOLL
frames. By default it supports up to 6 frames into collector's buffer now.
- Added "TXFrmMode" option (that was available in 9k6/19k2 version). It allows
to select the transmission mode of the frames.
If set "TXFrmMode=1" then it will repeat only one frame on each of REJ acks.
It can be useful in poor condition jointly with MAXFRAME up to 4. If another
station uses a TNC which can operate with "Frame Collector" this option can
improve a performance, especially on HF.
If set "TXFrmMode=0" then it will always repeat the block of the frames,
whose the number is limited by MAXFRAME. It can improve the efficiency in
good condition. Especially with TNCs without "Frame Collector" function.
By default this value is "1".
