为了听单边带，特意多花不少银子买了德生PL-600，但调试了很久，一个单边带内容都没有听到。据说广州海岸台比较稳，正好我的QTH离广州不远，拿着[广州海岸台](https://mp.weixin.qq.com/s/3dpmLAzmRNJfTYf6JJT9vw)的几个SSB频率对着收音机的调试，每个频率依然都是杂音，没有正常的信号声。已经熟读过收音机说明书，按了SSB键确保屏幕有显示SSB且频率也正确，在那几个频率下把SSB SFO旋钮慢慢调了个遍也还是不行。中波和短波倒是正常，能够收听到正常的节目。网上相关操作的帖子较少，求大佬指教。

第一，pl600是要调拍频的，有个中间档位手感大部分情况放在哪就行了第二，随机有一根长线天线把他拉直了挂出去再试，还不行就淘宝买根越长越好的0.2左右的可以导电的线拉直了挂出去

@"SuoYuC"#p34178 调拍频是调整SSB SFO 旋钮吗，是不是不能使用原装拉杆天线得用赠送的外接天线才行。

短波SSB要看有没有传播和有没有人呼叫。

@"BH1QAE"#p34343 广州海岸台难道只是偶尔有信号吗

反正我用20米端馈都没有收到过广州海岸台，一次都没收到过，QTH深圳。听单边带可以用PL330啊，又便宜。听14.270M频段或者7.023M频段都行

短波有越距现象，简单来说，就是离得太近反而听不到

好机机有了，但环境和天线同样也重要，建议先到城市绿地公园去试试

How can a radio be used to listen to single-sideband (SSB)?

SuoYuC

First, the PL600 is designed to adjust the tuning frequency. The middle setting generally provides the best feel in most situations.
Second, I randomly straightened out a long antenna and hung it up to try again, but it still didn't work. So, I bought a longer, better-quality cable (around 0.2 meters) on Taobao that could conduct electricity, straightened it out, and hung it up.

BI7KHZ

SuoYuC Is adjusting the SSB SFO knob the same as tuning the frequency? And if so, does this mean I can't use the original included antenna and need to use an external antenna instead?

BH1QAE

When using shortwave SSB, you need to check for signal propagation and whether anyone is calling.

BI7KHZ

BH1QAE Is the Guangzhou Coastal Radio station only sometimes transmitting?

BG7NOD

Anyway, I haven't received any signals from Guangzhou Coastal Radio using a 20-meter antenna, and not even once from QTH Shenzhen. If I use a single-band PL330 receiver, it would be cheap. It can receive frequencies of 14.270 MHz or 7.023 MHz.

BH4GQD

Shortwave radio exhibits a phenomenon called "proximity effect," which means that if you are too close to the antenna, you will not be able to hear it.

Hangying

I have the equipment now, but the environment and antenna are also important. I recommend trying it out in a city park first.
