The error rate is excellent over short runs, and the transmission speed means that a useful PPP link can be established between the machines. Будем смеяться или подождем, когда нас клюнет жареный петух, и начнем тогда соображать, что именно и как делаем во вред себе? Back to top David Holburn Last updated: 18:35 on 18th July 2008. For some radios (the DSE one in particular) you may need a comparator on the end of the inverting amplifier to clean up the square wave.

With the higher operating frequency, smaller coupling and bypass capacitors (C1, C2, C3, C4, C6) may be used than for the audio amplifier without adverse effect on performance. Its value is chosen so that it has a low reactance at the (medium wave) frequencies of interest, which therefore pass without hindrance. Изучаем программу “Cadsoft Eagle”. Прекрасное средство для разработки печатных плат. Сигурно друг би попитал защо не съм използвал сдвоени варикапи? Did you get it working? I would love to hear from successful constructors, and even unsuccessful ones. If you have problems with this circuit, try to describe them and I will do my best to help you out.

The amplitude of the transmitted radio signal or carrier is modulated — made to rise and fall — by another signal of audible frequency — for example, speech or music. Передача из оперного театра велась по двум телефонным линиям и воспроизводилась несколькими громкоговорителями. В 20-х годах были предприняты попытки стереофонической передачи по двум радиоканалам. Also, you will need two female RS-232 connectors, either 9 or 25 pin depending on what kind of connector the port uses. 3 core shielded cable is a good idea for the run from computer to tx/rx.
