DIY600W 功放 [复制链接]

哎　这个贴快成水贴了,tna的功放有没有什么新图贴贴出来?

定购一台572b，有消息通知一下哦！

pm价格，811的。谢谢

顶上来,看看有没有

山寨572b的瓶颈基本解决，磁性材料全部采用美标，与原机一样。其他零件的互换率争取达到90％以上。本次磁性材料如下：
1、全貌、漂洋过海走了8天。
2、t200-2
3、磁管（暂不公开）用于中和电桥，四只管子并联，分布电容比较大。
4、磁珠，导磁率很高u＝2500，没见过国内谁卖过。
还有一种螺纹铁粉芯磁芯，用于输入槽路，与原机同型号，下段时间从美国寄出。
既然山寨，就要有山寨的样！！！
海岛通联、移动使用572b还是不错的！

活着真好~

572b即将浮出水面，准备打渔。排队

真希望早日见到国产572b投入使用

弄好了请通知一声，到京来提，13272314057

听说-------

有一个挺不错的小东西，digital lector rf wattmeter。看着精致，功能强大，使用简洁。

愚谓之---“可以调素琴，阅金经。无丝竹之乱耳，无案牍之劳形。”

请看：

好玩儿吧？

虽有山寨之雅誉，实乃精心打造而成。俺是一机在手，别无所求，呵呵

那我就等山寨版的lp100a了！

经考察：4rf是久经考验的铁杆....
此人举棋不定，取消铁杆资格！

这个山寨标志如何？我画图不行，还是您老给谋划谋划，越土气越好。

嘘---

小点儿声，都听见啦

不是搞ft100了吗!?
572b也非常不错,牛

被4rf说破了。

再贴几张图看看：

暂命名--cz-100a

* per-band power calibration, user adjustable in 0.1% steps.

* frequency counter - user adjustable per-band corrections of all parameters.

* only meter with z, r, |x|, phase display... not affected by local broadcast stations as antenna analyzers can be.

* super wide autoranging power range of 50 mw to 3000w, 160-6m... perfect for qrpp through qro

* optional couplers for 5kw and 10kw. our 10kw will handle more power and generate much less heat than our competitor's.

* only meter with graphic vfd display. the graphic display allows for a solid bargraph with no gaps, and full screen scrolling screensaver as shown in the shot above with n8lp scrolling.


* only meter with simultaneous bargraphs for power and swr (or power and ref pwr).

* highest bargraph resolution. 90 segments gives 1% tuning resolution with standard bargraph range settings (adjustable)

* only meter that has a "sticky" bar to graphically show peak hold point even while bargraph is moving.

* fast attack bargraph will accurately display a single "dit" at over 100 wpm. decay adjustable for fast, med, slow.

* active temperature compensation. only other meter with this is alpha.

* true 12-bit a/d converter gives <1w resolution at 2000w. 13.6 bit effective resolution up to 360w.

* return loss (rl) display of 0 to 49.9 db with bargraph

* separate scale for dbm measurements, +15.0 dbm to +64.0 dbm with bargraph

* field strength input covers the range of -15 dbm to +33 dbm (0.04 mw to 2w)... great for beam pattern and bench measurements

* peak to average ratio screen. allows accurate checking and setting of compression in your speech processor.

* support within trx-manager for direct remote monitoring

* call sign screen saver - user programmable

* free plot program displays swr, z, phase, r+jx (including sign), reflection coefficient, return loss and smith chart.

* swr alarm with "snooze" mode for antenna tuning. alarm has led, ptt relay and audible sounder (which can be easily disabled)

* g4hfq's free polarplot program works with the cz-100a's field strength mode to provide automatic antenna pattern plotting. see software section of this web page.
