Icom IC 71 VHF Transceiver
Process:All parts are built with combined 3d tools like Bryce, Vue and Daz Studio. Then I transferred all parts in OBJ and put the model together in Daz Studio.The textures are made in Photoshop and then transferred to all parts in Daz Studio. (Note: The model is not suitable for 3D printing)
About:The IC-71 is a 50MHz AM transceiver produced in 1970. It was the company's first 50MHz multimode (AM/FM/CW) desktop transceiver. Its compact, elegant design and full transmit functionality—transmitting on the same frequency as the receiver—make it easy to use, with few unwanted signals and high frequency stability. It's a model that commemorates the 6m AM era. Although a small number of IC-71s were exported, they were primarily for the Japanese market, and few remain abroad. I bought this one
At an amateur radio show, thinking it might break, so I could tinker with it, or even use it as a test bench for my own project. Incredibly, it worked right away, without any significant problems. Initially, the received signal oscillated abnormally—a high-pitched, loud, and annoying squeal—but this was caused by a loose connection in the AF GAIN potentiometer, which opened the input and caused self-oscillation. Turning the knob fixed the problem.
The IC-71 covers the amateur bands from 50 MHz to 54 MHz, divided into four bands of 1 MHz each. Each band requires a crystal oscillator for reception and transmission. Crystal oscillators for the 50 MHz and 51 MHz bands are standard, but those for the 52 MHz and 53 MHz bands are optional. This model does not have the optional crystal oscillator.
