SoundAir SS-8450 80ch 10W AM改造機の出品です。、
出品は無線機本体のみで、パワー計や同軸ケーブル、電源コードやマイクなどは付属しません。

3年前にヤフオクで入手し28MHzにも出られるように改造しておりましたが、使うことが無いので処分します。
出品にあたり、送信と受信ができ、送信パワーも10W程度あり、エコーやスタンバイピー、SWR計など
短時間ですが一通り動作することを確認しました。(SGとダミーロードを使用して確認)

内蔵スピーカーから音が出ます。
Ch表示のLEDに文字欠けはありませんでした。
パワー切り替えは写真のとおり、H=10W/M=3W/L=1W程度です。
エコーは動作していますがエコーレベルの調整が難しいです。
スタンバイピーはダミーロードでは動作してますが、アンテナをつなぐと回り込みで誤動作しやすいので使用することはお勧めしません。
電源コードはNASA用またはユニデン用の3ピン電源コードが使えます。
マイクはNASA 4ピン配列ですが、マイク無しでも受信可能です。


BAND切り替えがHで28MHzです。
41~80chは28MHzのアマチュア無線バンドで28.095MHz~28.535MHzまで10kHzステップで一部歯抜けありです。
41ch=28.095MHz 50ch=28.205 58ch=28.305 67ch=28.405MHz


※入手時に不具合があり、下記修理/調整をしております。
・ファイナルトランジスタ破損でを2sc1307から2sc1969に交換
・パワー切り替え用トランジスタ破損で2sc1096を2sd2012に交換
・SGを使って受信調整
・スプリアスは-55dB程度です(調整時で現在はどの程度か測定していません)
・28MHzでスプリアスが少なくなるようにスペアナで確認しながら調整
・変調リミッターカット(ほとんど効果ありませんでした)
・一部電解コンデンサを交換

27MHz(FCC)でも送信しますので、アンテナをつないで使う場合は送信禁止処理されるか、
ダミーロードでの実験/研究用としてお使いください。
アマチュア無線での使用も可能ですが、28MHz以外での送信ができないように処置した上で許可を取ってからご使用ください。
簡易的にはバンド切り替えのL側の配線を切るのが手っ取り早いです。

古い機器であり資料もありませんので、クレーム/返品/返金/サポートは受け付けません。
また、今後の動作保証についてもできませんので、動作するジャンクとの認識でお願いいたします。

出品にあたり簡単に清掃していますが、傷/汚れ/錆がありますので、新品のようなコンディションを
お求めでしたら入札しないでください。

60サイズ程度の箱に入れますが、重さがあるので80サイズとして発送します。
箱や緩衝材は再利用です。

発送はヤマト運輸の宅急便みです。
ゆうパケットポストminiでは発送しませんし、ゆうパケットポストminiを選択されても発送できませんので、落札されてもキャンセルにします。

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.
