电压太低了 电流会增大 应该15~16v

我试调了电压15-16v,接收电流没啥变化.接了高阻耳机,收ssb象听广播,哈哈!

哈哈,接收搞定了!音质不错!

陈老师再把电键接口试出来就基本能用了

我感觉接受效果和操作手感要比133好,音质不错,我把音频接到一个单声道插座里,用线间变压器转换接8欧喇叭,听am广播声音很清晰,感觉和收音机效果相差不大.

我在7050/a3j-听了很久,接收微弱信号的能力也不错.133跟它比不是一个档次的东西.

接受发射都高出来了 cw ssb am 都可以接收和发射了 就是没收装用的接头啊 不好搞啊 h g   是cw ptt公用 a c   为 mic     e f 为耳麦     如有错误 请 指正, 谢谢  

有点存货可以用上了 呵呵

rc-300-2 ( trc-302 ), trc-300-3
built by thompson-csf, the trc-302, or more accurately, the trc-300-2, entered service in 1972. if compared with u.s. equipment of that time ( prc-74 ), it would have boasted several advanced features. these would include smaller size, greater frequency coverage, better ergonomic design, and operational mode flexibility.

the trc-302 is an hf all mode backpack set, as such it is one of only two sets of it's type to be encountered, the other being the racal tra-931. if compared with that radio, the trc-302 is of a smaller size, better mechanical construction, more advanced circuit design, is completely water tight, and operates from a lower supply voltage, thus overall better suited for a front like combat environment.

it's controls are all arranged down one side of the radio as is common in european designs. this fashion does afford better access to these controls by both a secondary, and primary operator while it is in position on his back, also some measure of protection from weather.

though it would appear that they might be more vulnerable to damage under combat conditions. the only known radios in u.s. inventory to utilise this configuration, are also of foreign origin.

features include lightweight waterproof aluminium alloy case, usability by unskilled operators, cos/mos synthesiser design with extreme stability, and maximised use of integrated circuits and other solid state devices, with no mechanical relays. modulator internal design utilising plug in modules and circuit boards. ancillary equipment that will allow it's use as a vehicular or semi-fixed station with power levels up to 100 watts.

ops 2-30mc, in 1kc steps ( some models 100cps steps, and pre-set channel ability ). rf power output is rated 20watts high, and 6 watts low, from a 14.5 volt 4 amp hour nicad battery. modes include usb, lsb, cw, ame.

for the most part the trc-302 is one of the more attractive radios sets known to be in use by the iraqi's, though it too is a dated design, and no longer believed to be in production. it is reported to have seen wide spread use in africa, south america, the middle east, and australia.

for trc-552 and trc-570, see section ( ii ) iraqi domestic production radios

玩了个玄的.加上了24v电压.发现错误时已待了一分钟.庆幸没坏.
