高性能便携式十米机DIY项目 [复制链接]

继续支持何工！

BD5UYW:谢谢BG8SZG评价！做到性价比高很累，呵呵！
我的业余diy，都没有升级空间，功能参数直接到顶，芯片都是用到没ROM空间。
我只能换平台或电路才能做下一个同类作品，～老毛病呀，想改老是改不 .. (2012-09-23 00:46) 

岁岁年年机求精，年年岁岁心急疯！

好一个大忽悠贴！再有三年机器也不会出来的，不信走着瞧。

明年肯定能出机器 走着瞧

朋友，你肯定学不好技术~ 搞技术要沉得住气，要多看多学。

刚从香港回来，这次展览会上有我好多的作品展出，其中展会的官方杂志
封底就有我的作品，那机器也开发了快三年才展示出来，有兴趣可以看看~
我可以用高端的作品“忽悠”洋人，干嘛来这辛苦的忽悠国人呢？

何工，哪里可以看到展会的作品？给个链接嘛！

技术并不是每个人都能学好，我肯定是学不好。
-----------------------------------------
对DIY爱好者你可以连续忽悠四年而不出机器，这算是个奇迹吧！
展会上你的作品再好和本帖也没什么关系，无数的人顶了你148页，支持你，赞美你，换来的就是4年漫长的等待，你不觉得愧对那些人吗？
帖子早期基本测试通过的机型估计你早已做成自己商业化的电台了吧！

业余设备的数量和价格一直都是DIY设备的大问题！

如果有足够的数量和有合理的价格让何工专一的开发这款电台，估计也花不了多少时间就可以正式销售。

现在的问题是：是先做维持生活第一的业务机还是先做不好赚钱并且出力不讨好的业余机？

呵呵，答案相信很多人都有了吧！

业余无线电本来就是有业余时间才折腾的爱好，既然是有业余时间才来折腾的爱好，如果和业务有冲突，自然是永远排在业余的时间里才去玩去做。

呵呵，所以何工出不出或是几时出这款机器对于我来说无关紧要，出来我就买，不出来也没关系，毕竟人家的生活和业务才是第一，千万别给自己和别人套上什么圈圈，那样实在是没意思……。

8UK正解！
DIY业余机90%的项目是赔钱的，所以要有100%的热情和100%执着。
我是掌握最多DIY资源的HAM之一，我承认我看到了这个问题，所以我是本着发烧
的目的做项目的，不会在DIY项目上图利。至于定价，说真的，即便是定个日机的
价格，也是赔钱的，因为数量摆在那。我现在的思想是如何做好DIY机器，当然这
是业余时间来完成，那我的业余时间是什么呢？就是专业设计的空档时间。

香港亚洲展览馆通信电子展，链接不放上来了免广告嫌疑：）

抱歉呀，此次比较匆忙，是乘香港私家车从深圳湾大桥直接入港，到展会看一圈后，原车返回深圳，没有在港停留。

坚持\\\\\\\\\\\\\\\\\\\\\\\\\\

展会是展出了什么产品啊？给个照片嘛！

要是提前说一声我还能直接过去香港看看！

这应该是老何参展的机器了，泉州邦德通讯有限公司

Car Two-Way Radio

Model No: FT-2900R Product Specifications: This car two-way radio allows you to have clear communication while on the road. The functional two-way radio provides a total of 221 memory channels including 200 regular channel memories, ten pairs of band-limit memories, and an instant-recall home channel you can dedicate to a frequently-used repeater or simplex frequency. The large 6-digit backlit LCD display ensures excellent visibility. 75W power output. 75W of solid RF power with no need for cooling fan. Four selectable power output levels are provided: 75/25/10/5W. The power selection may be stored into memory, allowing you to conserve power while using strong local repeaters. Loud audio with internal speaker. Excellent receiver performance. The FT-2900R' s receiver front end features Yaesu’s renowned Advanced Track Tuning RF input filtering, which affords outstanding protection from Intermodulation distortion. Built-in CTCSS and DCS encode/decode. For easy repeater access, or silent monitoring of busy channels, both CTCSS and DCS (digital code squelch). Encoder/Decoder circuits are built-in. CTCSS and DCS configuration data may be stored independently in each memory channel. A “split tone” mode also allows operation on systems where CTCSS and DCS are used separately on the repeater uplink/downlink. Extensive memory System Memories can store repeater shift information, CTCSS/DCS data, power output level, scanning status (“Skip”), and Alpha-numeric labels. Alpha-numeric channel display Memory channels may be displayed either with the channel frequency or a personalized Alpha-Numeric label, for easy channel recognition. Up to six letters, characters, or numbers may be used for labeling channels. A special 10-channel weather band memory bank is provided in the U.S. version, allowing quick access to NOAA weather broadcasts. When the 1,050-Hz “severe weather” alert tone is transmitted, the FT-2900R may be configured to emit an alarm tone to get your attention quickly. With the “weather alert” feature enabled, the FT-2800M will scan the ten Weather memories, stopping only if the 1050-Hz tone is received. MH-48A6J DTMF direct access microphone. The backlit MH-48A6J microphone allows direct keypad frequency entry, or keypad memory channel recall. On transmit, the MH-48A6J allows manual entry of DTMF tones for autopatch use, and the FT-2900R also includes a nine-memory, 16-digit DTMF auto-dialer.
