DIGITECH AR1945,与曾工的原设计图样是一模一样的:
有澳洲发烧友为这机写了机评:
SWLing Post reader, Phil, comments:
This radio has been released in Australia via the Jaycar Electronics Stores as the Digitech Audio AR 1945. It has all the hallmarks of Redsun radios.
I bought one and overall the performance is very good on MW and SW, FM is ok and AIR band isn’t too bad. The big drawback is the SSB. It is dreadful, by far the worst SSB demodulation I have ever come across in a radio. This needs to be addressed and once done so, will be a good receiver.
Pity it doesn’t have Synchronous detection as, if you look at the display carefully, provision has been made for this feature. I wonder how it can be activated? I would appreciate any comments on a fix for the SSB
Phil, thanks so much for the mini review. Here’s a link to the AR1945 on Jaycar’s website:
http://www.jaycar.com.au/productView.asp?ID=AR1945
Has anyone found a mod to activate a potentially dormant sync detector or to improve SSB demodulation? Please comment.
I’ve posted various views of the Digitech AR1945 below, along with this full description from Jaycar’s website:
“Ideal for a novice ham radio licensor, keen fisherman or even just the outdoors type, this radio has everything you will ever need in a radio with the added function of single-sideband modulation (SSB). SSB is used to obtain current weather reports, so it is perfect to take to sea to avoid changing weather conditions. However with great FM and AM coverage and battery operation it is also perfect for camping, BBQs and thanks to its world/local time selection clock and alarm, it can even be used as an alarm clock! Additional features include auto tuning saving, 500 memories and keypad direct entry. This is certainly a radio of many uses! Power options are 6 x AA (not included) used with supplied 6 x D size battery adaptors, 6 x D batteries (not included) or the supplied 9V PSU. Supplied with a carry strap.”

SWLing Post的读者菲尔评论道:
这台收音机通过Jaycar Electronics Stores在澳大利亚发布,作为Digitech Audio AR 1945.它具有Redsun收音机的所有标志。
我买了一个,总体而言,MW和SW的性能非常好,FM还可以,航空波段也不错。最大的缺点是SSB。到目前为止,我在无线电中遇到过最糟糕的SSB解调,这是可怕的。这需要解决,一旦这样做,将是一个很好的接收器。
可惜它没有同步检测,如果仔细观察显示器,就可以为此功能做好准备。我想知道它是如何被激活的?我将不胜感激任何有关修复SSB的意见。
菲尔,非常感谢你的迷你评论。这是Jaycar网站上AR1945的链接:http://www.jaycar.com.au/productView.asp?ID = AR1945
有没有人发现mod可以激活潜在的休眠同步检测器或改善SSB解调?请给出意见。
我已经发布了以下Digitech AR1945的各种视图,以及Jaycar网站上的完整描述:
Digitech AR1945便携式收音机“非常适合新手火腿无线电许可证,敏锐的渔夫,甚至只是户外类型,这款收音机拥有您在收音机中所需的一切,具有单边带调制(SSB)功能。 SSB用于获取当前的天气报告,因此非常适合出海以避免天气变化。然而,凭借出色的FM和AM覆盖范围以及电池操作,它也非常适合露营,烧烤,并且由于其世界/当地时间选择时钟和闹钟,它甚至可以用作闹钟!其它功能包括自动调谐保存,500个存储器和键盘直接输入。这当然是一个有很多用途的收音机!电源选项为6 x AA(不包括),与随附的6 x D电池适配器,6 x D电池(未提供)或随附的9V PSU一起使用。随身携带。“

Richard Reviews the Digitech AR-1945
I just received my Digitech AR1945 yesterday directly from Australia. It arrived in only 3 days but at $72US, the import costs are steep. It arrives well packed and in a nice box. The radio is about the size of the Grundig 450 offering. It uses the same front mounted tuning dial as the 450 does. It feels heavy and doesn't sit perfectly straight but is better than the other offerings from these Chinese made radios.
The Digitech supplants the wobbly band and bandwidth knobs for buttons. This is a very nice change. The 5 watt speaker sounds amazing too. There is no dedicated light button, but you can set a switch so that all the buttons light up when you engage the radio. After much research, I do think this is a rebadged Redsun RP-3100 which I am not sure ever came to market?
FEATURES: Wow does the Digitech offer features! But...do they work? Well, yes and no. The Digitech takes SSB listening to a new level, splitting rhe fine tune first into 1/10th step and then for super fine tuning, it offers a 1/200th step that is organized as -0-99+99-0. This should allow the user to really pinpoint the signal. It doesn't. No matter how much I fiddle with the fine tune, I cannot get the "garbled" sounds out of the voices I hear. I was frustrated but not surprised.
On MW, below 900Khz, there is a buzz or grinding sound that accompanies your tuning efforts. Then...it locks onto a frequency and you are shocked at how well it locks on. It's as if there is an auto sync detector running in the background.
SW is good and much like the other offerings in this group. While FM sounds good, I would say its overall FM reception is average at best...similar to the Grundig 450 or CCRANE-SW.
I also have the Anjan DTS-10. I love the looks of the Anjan. With this one, there is a significant bug with the FM band but everything else works well enough. The Anjan uses a BFO tuning knob where the Digitech attempts to use dedicated USB/LSB button configuration. The difference is that the Anjan can clearly copy SSB without the garbled voices.
The Anjan is smaller. It has a cool display too. You can set the backlight on even in battery mode. I can see why Eton and CCrane will not offer so-called enhanced featured radios at this juncture. Too many bugs??? While the Digitech and Anjan offer a lot of bang for the buck, I personally cannot recommend them because each radio has its bugs. If you can live with these bugs, as I can with the Anjan's FM bug (I have plenty of FM radios), then go for it. They are cool novelties and I do plan to use them.
Tecsun has worked out sync, so I am hoping these guys will get it right too eventually. I think the market is ready for a higher end receiver.
I hope this helps.
Regards,
Richard Griffith

Richard评论Digitech AR-1945
我刚刚从澳大利亚直接收到了我的Digitech AR1945。它仅在3天内到达,但售价为72美元,进口成本非常高。它到达包装好,在一个漂亮的盒子里。收音机大小与Grundig 450产品相当。它使用与450相同的前置调音拨盘。它感觉很重,不会完全坐直,但比这些中国制造的收音机的其它产品更好。
Digitech取代了按钮的摇摆带和带宽旋钮。这是一个非常好的变化。 5瓦的扬声器听起来也很神奇。没有专用的灯光按钮,但您可以设置一个开关,以便在您使用收音机时所有按钮都亮起。经过大量研究,我认为这是一款重新推出的Redsun RP-3100,我不确定它是否会进入市场?
特点:Digitech提供的功能哇!但是......他们有效吗?嗯,是的,不。 Digitech将SSB聆听到一个新的水平,首先将微调分成1/10步,然后进行超微调,它提供了1/200步,组织为-0-99 + 99-0。这应该允许用户真正精确定位信号。它没有。无论我调到多少微调,我都听不到我听到的声音中的“乱码”声。我很沮丧,但并不感到惊讶。
在MW低于900Khz时,伴随您的调音工作会产生嗡嗡声或磨音。然后......它锁定在一个频率上,你对它锁定的程度感到震惊。就像在后台运行自动同步检测器一样。
SW很好,很像这个组中的其它产品。虽然FM听起来不错,但我会说它的整体FM接收效果最好......类似于Grundig 450或CCRANE-SW。
我也有Anjan DTS-10。我喜欢Anjan的外表。有了这个,FM乐队有一个重大的错误,但其它一切运作良好。 Anjan使用BFO调谐旋钮,Digitech尝试使用专用的USB / LSB按钮配置。不同的是,Anjan可以清楚地复制SSB,而不会出现乱码。
Anjan比较小。它也有很酷的显示效果。即使在电池模式下也可以设置背光。我可以看到为什幺Eton和CCrane在这个时刻不会提供所谓的增强型特色无线电。太多的错误???虽然Digitech和Anjan提供了很多优惠,但我个人不能推荐它们,因为每个收音机都有它的错误。如果你可以忍受这些错误,就像我可以使用Anjan的FM bug(我有足够的FM收音机),那就去吧。它们很酷,我打算使用它们。
Tecsun已经计算出同步,所以我希望这些人最终能够做到正确。我认为市场已经为更高端的接收器做好了准备。
我希望这有帮助。
问候,
理查德格里菲斯
