The WSPR 7-bit power field contains the raw dBm value (0-60) with no offset. The decoder was subtracting 64, turning valid power values into negative numbers that always failed the range check, causing unpack_message to return None for every real signal. Also fix callsign trimming to strip leading spaces from space-padded callsigns. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> Signed-off-by: Stanislaw Grams <stanislawgrams@gmail.com>
