Tsananguro yeChigadzirwa
1. Pfupiso yeChigadzirwa
Inoshandiswa zvakakodzera mukutumira ma "bi-directional transmission" (inogona kuchengetwa) uye kuenzana kwechiratidzo chekutumira ma "multi-class trunk" kana network yekuparadzira inodiwa zvakanyanya. Adopt PHILIPS, NEC imported power doubler modules. Audio pre-amplifier i "low-noise microwave tube push-pull amplifier" kuti ive nechokwadi chekuti yawana simba rakawanda. Ine "input" imwe chete uye "2 outputs", uye kubatana kwega kwega kune dziviriro ye over-current. Bazi rekubudisa kana "distributiveness" rinogona kuchinjwa mushure maro. Double-equalizer inoshandiswa, saka kugadzirisa "multi-class transmission flatness" kuri nyore uye kuri nyore. Attenuator ne "equalizer" zvinoshandiswa pa "plug-in", saka vatengi vanogona kusarudza "fixed" kana "adjustable style". Simba re "switch" rakavimbika (kana "linear power") uye dhizaini yakasimba ye "waterproof" uye "anti-thunder" inovimbisa kushanda kwenguva refu.
