![]() ![]() Cable for RRxD and RTxD connections should be shielded. LP2950 is replaceable with LM2951 with appropriate resistors, 78L05 is the worst choice due to it's own high current consumption. Fast silicon diodes of any type will do, for example 1N4148 or LL4148 in MiniMELF case. Bokhanov) VT1, VT3, VT4 transistors may be BC847 or similar (i.e. Schematic diagram Connection circuits (jacks for mobile radios are shown as they are plugged into sockets) GP-340 connector (draft by K. Jual Radio komunikasi Handy Talky Radio Rig Repeater Radio Marine SSB Air Band Antena jual battery HT pengiriman ke seluruh Indonesia. Another goal is the correct voltage level transformation with regard to the real radio programming circuits. That is because the COM port's logic one is a low voltage level, logic zero is a high voltage level. The main goal of this cable schematics is the invertion of signal levels. The programming cable is intended to be used with a computer RS-232 port for programming radios and other devices. Hi RadioPixie, I have just got my self a DR135 and programming cable. Would software would you recommend to open it up? Does seem to be anything on my computer (Windows 7) to do the job. I have downloaded the software for the Alinco DR135DX and it's a.rar program.
