Doug - Are you saying that your antenna gain switch works on MW AM (AM Broadcast Band)? This feature was supposed to be introduced in Ver 3.

The main feature I'd want in the higher versions is the ability to manually switch between 1 and 10 kHz tuning steps, and not always have to use the 1/10 kHz automatic switching. I have a PL-380 which uses the latter, and I am not a big fan of the auto switching.

There's a version 3?? I have the version 2 - at least I think I do - and the Loc/DX switch does have a noticeable effect on MW for me.

Here's some more info on PL-660 version numbers (from Yahoo TecsunPL660 group, message# 204). Maybe the version number the box is not meaningful.

Tecsun may have bought more pre-printed boxes labeled "Version 1" than the number of "Version 1" radios they produced.

While the serial numbers are pasted on the box later, the version number is preprinted on the boxes.

My box is labeled version 1, but my radio has many of the features that were supposedly added and/or corrected later?!?!

On my PL-660:

1. Listening to a MW/AM station, toggling the "ant gain" switch between the 3 available positions does change the antenna gain.
2. Pressing the "light/snooze" button, the backlight comes on for 30 seconds.
3. Pressing any of the other front panel buttons, the backlight comes on for 3 seconds.
4. When rotating the tuning knob, the backlight will stay on continuously until rotating stops and then it goes off after 3 seconds.
5. The unit allows manual selection of any of the 3 "slow/fast/auto" tuning steps when using the tuning knob.

It may be a later version in a version 1 box.

Is there any way to tell the version number from the serial number?

Gary: My experience exactly, 1-5 above. Yet my box has Ver. 1 printed on it. So it sounds as if I have a 2 or perhaps a 3. I just did an Ant Gain MW check with several weak stations. On both, Local produced barely audible audio, Normal a listenable but mediocre audio (say 5 or 6 on a scale of 10) and clear and clean, noise free audio on DX (a 9.5-10). So I apparently don't have the Version 1 my box indicates. Whatever, I am delighted with this radio, every aspect of it.

Gary

Doug - As best I can tell from the Yahoo group, you have a Version 3 radio, so keep enjoying it. I may pick one up sometime as well.

Tecsun should just put the version information on the radio itself, and not on the box flap.

Dan

To follow up, my box says version 1, even though I was assured by the ebay reseller that I was receiving version 2 when I ordered it in late December. I do not notice any distortion on AM like the version 1 is supposed to have, but not sure what other upgrades version 2 is supposed to have...

Gary

Dan - My understanding is that Version 2 should have items 2-5 listed above, but probably not item 1.

The version 3 has problems after connecting external antenna. It disconnect some protecting diodes and some static electricity around - finish. My radio has constant noise and some waves of huge noise sometimes. It's most hearable on AM and SW band. Probably wrong circuits assembled in factory. And Im not alone with this problem. Some other people had worse - radio stopped working AM band after connecting external antenna. Version 3 is thus not much improved, rather I would say, this problem occured and I hope it will be fixed in next versions or production runs.
