Tecsun PL-660 Review Over All : Tecsun PL-660 感想

I bought this portable last month. I like this portable. Especially shortwave reception with build-in whip antenna is very good, I think. And far better with Ext antenna.

Added note:
During my vacation, I played with PL-660, I noticed following.
Pros:
1. Not bothered with images (ghost) even when EXT. antennas with preamp.
2. Selectable RF Gain controll works properly.
3. SSB mode works very good to reject QRM or man-made noise. And easy to tune.
4. PLL controlled but no stepping noise. It's really nice.
5. Sync detector works. But only under regulated conditions. For example when target is strong enough, and QRM or sprious noise is weak.
6. Sensitive enough with build-in whip antenna.
7. Small electricity consumption.
8. Battery voltage is selectable. It works properly either at 6V or 4.8V(Ni-MH)

Cons:
1. SSB tuner has a clicker on the centre. So it stands in the way of fine tuning.
2. A little noisy especially in Sync Detect mode
3. Sound volume is poor in SSB mode
4. SSB reception is very good but not stable.

Neutral:
1.I don't understand how to use memory function at all. It's very similar to that of Grundig Satellit 750 (Tecsun S-2000). Also I don't use "scan" function at all, so I don't know about it, either.
2. Selectivity is not so good in AM mode.
3. Sound quality is as its price, nothing special.
4. Tecsun recommands to use DX mode usually, but I think DX mode is amplified. In DX mode, more ghosts and satulation especially with EXT antenna.

長所:
1. 外部アンテナやプリアンプを使っても、オバケがほとんど出ない
2. AFゲインは有効です。落とし気味の方が良い。
3. SSB はとても良いと思います。操作もしやすいです。
4. De1103のようなマニュアルチューニングダイヤルを回している最中のプチプチノイズが出ません。
5. 同期検波は、目的局が混信よりも強いときは有効です。逆は無理です。
6. ロッドアンテナでもDe1103と同程度の感度はあります（SW）。
7. 消費電力が少ないです。電池の持ちは良いです。
8. 6Vと4.8Vのどちらにも対応しています。充電池でも十分な性能が出せると思います。

欠点:
1. なぜだか分かりませんが、SSBのチューナーのセンターにクリッカーがあり、チューニングの際とても邪魔です。
2. 同期検波で受信すると、若干ノイジーです
3. SSBで受信すると、音が小さいです
4. SSB受信は良いですが、安定度が今ひとつです

分からないorどちらでもない:
1. スキャン関連とメモリー関連はいつもそうなのですが、宝の持ち腐れで全く分かりません。メモリー機能は以前持っていたGrundig Satellit 750とソックリのようです。
2. 音は取り立てていいわけではありません。硬いです。
3. AMの選択度はあまりよろしくありません。というか、普通のポータブルです。
4.. 取説によればメーカーはDX modeでの使用を推奨していますが、Normalモードが増幅されているようで、簡単にオバケが出たり、飽和します。特に外部アンテナを使用すると顕著です。

Hello from China. I really didn't know PL-660 had been sold by now. I have a PL-600. For MW band, I think there are many broad band width radioes in Japan?! So is there a quite significiant difference in voice quality to listen to those radioes with choosing broad band width of the receiver?

[pesnyaozemle]

@superarticulation Does "broad band width radios" mean " general coverage (LW~MW~SW) receivers/radios"? If so, there're only a few made-in-Japan receivers and radios on market.

Concerning the sound quality of portable radios on market now, I think "Sangean 909X" made in Taiwan is the best so far.

I love Tecsun PL-660 not because of its sound quality but of its Sync AM function and selectivity and sensitivity.

I've uploaded some videos on PL-660, please check them if you like.

Thank you !

@pesnyaozemle OH... It was not the mean I wanted to say. I have a PL-600, there is a band width buttom which can change receiver's band with between 6KHz and 9KHz of AM mode. For example, when listening to MW stations, you can switch to 9KHz band for clearer sound.

@superarticulation Oh, sorry. Indeed, the wider band width of IF filter, the better sound quality only when signal is strong enough. From the view of sound quality, I like Sony ICF-EX5. And I love Degen DE1103 made in China. It's not expensive radio but the sound quality is very good, I think. And again I hear Sangean ATS-909X is very exellent receiver concerning sound quality. Tecsun PL-660 has nothing special about sound quality, I think.

@superarticulation And I've uploaded a video comparing PL-660 with some portable radios. The title is "Tecsun PL-660 : Comparison of FM Sound"

Is it better overall than PL-600?

[pesnyaozemle]

@copypaiste Hello from Japan. I don't know because PL-660 is my first "Tecsun" brand radio. Thank you for your interest!

@senderjaeger Hello. This is my first Tecsun's Radio. Except Sync Detector, I like this radio. Thank you for your comment!
