[uSDX]
２個注文したけど１０個入っていたのは、1セット5個だったか・・(^_^;)
エアクッションの封筒に10個の長さのケージを切って入れてあるだけだったので、ケージ端っこの石の足は折れ曲がっていました。
ラベル印字は念の為確認しましたが、LM4562でした。
X_TALの値を変更してみましたが、LCD表示とCLK0出力のズレは解消しませんでした。
手持ちのキーをMIC/PTTに挿してみたところ、２pinジャックを挿すとKey InしなくてもGNDに落ちてしまい、Txモードになってしまうことが発覚。
これはKeyのピンの取り替えでなんとかします。
ArduinoでATmega328Pに書き込みをして...Done!が表示された後でも、実際にはATmegaには書き込みをされていないことがあることに気が付きました。
見出しのuSDXの部分に日付などを入れることで確かめられるようにしました。
- 電圧について
ブログで電圧についての記述があったので引いておきます。

1. I do not have a LPF module completed and installed yet (still waiting on parts).
2. I have checked and confirmed the components are in the correct location and are marked with the correct values.
3. I have checked with a magnifying glass for shorts and solder bridges - none found.
4. I programmed the ATMega328PU with avrdude and an old QCX radio and I am still waiting to try and program it with the Uno whenever it gets here.
5. I do not have my own decent/reliable oscilloscope (yet). I do have a cheap DSO pocket oscilloscope and/or I can take it to a friend who does have a good oscilloscope.
