★★幻のIC★HM63021P-28★を2本で!残少最終特価デジタル復調用★★
ご存知日立の遅延メモリーICです。
残り少ないデッドストックです。ピン折れなどはありません。
1988年製のICですがけっこうきれいです。
もちろん未使用新品です。PSK復調にトライする方にお譲りします。
検索用 デジタル 無線 PSK 警察 位相変調  
このICの使い方は検索エンジンでICの品番を入れて探すとたくさん出てきます。
ご参考までに。予備のために複数個御入用の方は落札御御相談下さい。
ほんの少しですが在庫あります。 検索用: HM63021、63021、PSK復調.

生産年月は変わる場合がございます。
このほかに数本持っていますので複数個ご入用の方はご相談ください。
写真では写り方の関係か足が腐蝕しているように見えますが実際は全く問題ありません。
次世代デジタル方式導入が進んでいるようです。
次世代方式の復調においてもこのICがキーパーツとなるであろうとの情報をいただきました。
残り少なくなりました。
トランジスタやICは真空管より後から作られた新しい素子ですが生産中止になったものを探すのは
真空管に比べて非常に大変です。
真空管は実際探すと価格は別にしてどんなに古いものでも比較的簡単に入手できていまいます。
その理由は・・・真空管は同じ番号のものが多くの会社で作られていたこと。
それに対して一部の汎用品を除くトランジスタやICは開発メーカーのみの生産でした。
そして生産国が変わればトランジスタなどは番号の付与方法まで変わってしまいます。
真空管はソケット式なので機器を捨てる前に何かの時に使えるかもしれないと思い
必ず真空管だけは抜いて捨てました。
そんな理由でディスコンになった半導体は非常に入手しにくくなっています。
アジア諸国の中では基板から外した半導体を専門に売っている所もありますが
極限られた数量ですし半導体の中古品は信頼性に乏しく使いたくありませんね・・・。
もう日本国内では手に入らなくなってしまったトランジスタやICを海外で見つけて買って参りました。
価格はけっして安いものではありませんでしたが無いと困るもの、代替えの利かないものなどを
探してきましたので、みなさまにおわけしています。
どうか大切に使っていただけますようお願いします。

International Shipping Methods
Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao.my and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters). After sending the email, notify us in the customer service message. We will confirm with the seller as soon as possible. and if there are any related questions, we will contact you through the customer service message. Thank you for your cooperation."

Please provide:
1. "Product ID"
2. Photo of the "Delivery Note" (if any)
3. Photos of the outer box (including inner and outer packaging)
4. Photos of the product (Please include relevant descriptions to help us confirm with the seller)

Important Notes:
1. Do not include foreign text or other products in the background of the image.
2. Please keep the complete product packaging (including the shipping label information), and refrain from repairing or altering the original condition on your own, as any changes may result in the case being unable to be processed.
3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
3. Transport Damage: If the goods are damaged during international shipping (to the pickup point), you need to provide photos of the outer packaging of the parcel and clear photos of the damaged goods' outer packaging.
