[jamsat-bb:6458] DSP-93とP3T.EXE について

岩本さん、jamsat-bb各局

＞ # DSP-93のLED点滅，ドキュメントが ない のだけど
＞ # チューニングメータ的な動作しているのかな？ やっぱりロックだけ!?
LEDは１、２番SYNC検出、３番PLLロック、４番はドップラーチューニング
のパルス、６番入力レベルです。TAPRのCD-ROMに入っていた簡単な
ドキュメントを下に添付します。

私もP3TからDSP-93へのプログラムダウンロードはうまく行きませんでした。
D93WEからダウンロードしてからP3Tに切り替えています。
できたとしても、ボーレイトを切り替えなければならないので面倒。
これでうまくいっているのでそれ以上追求せず。

Hi Gang,

These updated programs are for AO-13 telemetry and they will directly
feed the PC3.EXE AO-13 telemetry software. Contact w8gus@tapr.org
for more information on P3C.EXE.

Versions:

      p3c93t1.obj       radio port 1, ground to tune
      p3c93t2.obj       radio port 2, ground to tune

NOTE: DATA IS OUTPUT FROM THE DSP-93 UART. YOU DON'T USE THE TNC
WITH THIS PROGRAM. Data is output at 1200 bps, and DCD handshaking
is implemented as needed by P3C.EXE.

ON upper SSB, adjust the audio so the amplitude LED (6) is about
30-50 % lit as showing some variation. Start from a frequency well
below the AO-13 telemetry signal and tune upward slowly to grab the
carrier at 1200 Hz. When lock occurs, LED 3 will light. If you
continue to tune upward manually, the doppler tuning LED (4) will
light and tune the radio back down, assuming you have the down
tuning line hooked up. Otherwise, LED 4 will remind you to manually
tune to correct doppler drift.

The two LED's on the far left light up tell you that you have detected
the telemetry "sync" vector - you get 514 characters and it pauses until
it decodes another sync vector.

When you exit this SW the UART will be set up for 1200 bps so reset the
DSP-93 to get back to 19200.
