Some other similar projects, using Arduino as a CI-V interface:
#Icom ci v schematic full#
The 10 k ohms potentiometer is used to attenuate the signal output (which is too high for most analog meters) and calibrate the analog meter to get a full scale reading with a powerful local signal (+60 dB). The +12 V DC to the S-meter is not necessary it could be used to power meter backlight or any other optional features. You can use the CI-V "00" universal address on some Icom radios, making this converter compatible with any Icom radio, without changing the CI-V address in the code.įerrites are installed on input & output cables to eliminate RF induction. This project is designed for an Icom IC-7000 transceiver, but it can be adapted to any Icom radio with a CI-V port.
#Icom ci v schematic Pc#
If you don't have an Antenna Tuner connector, you can use a PC computer power supply connector, and trim it with cutters to fit the Icom tuner connector. An external DC power source can also be used. If your Icom does not have a tuner port, you can use any other port or connector that provides a +12V output (at least 200 mA). It is powered by the Antenna Tuner port on the Icom radio. This also works in satellite mode, where the downlink is on the main band.This circuit uses an Arduino Uno or Nano to send a CI-V command to an Icom radio to ask for signal information, read the answer, convert it and display it on an analog output, where you can connect an analog (Arsonval) S-meter.
Since Microsoft assumes this device to be a Microphone, this defaults to 1 channel, 16 bit, 44100 Hz (CD Quality) ….Īfter changing this setting to 2 channel, 16 bit, 44100 Hz (CD Quality), main band audio of my IC-9700 comes out of the left computer speaker and sub band audio out of the right one. Now IC-9700 audio should come through your computer’s speakers.įinally, select the Advanced tab and and verify the Default Format. Next select your device to show the device properties, then click on the Listen tab and check the Listen to this device box to route incoming audio to your computer’s Playback device.
#Icom ci v schematic windows 10#
Note that Windows 10 assumes this to be a Microphone… Now select the Recording tab, my IC-9700 is labelled as 3- USB Audio CODEC. You can type Win-R (run) and enter mmsys.cpl to open the sound settings applet without searching through (1.0E+6) setting screens first. Next step, is to check Windows sound settings. Not only in the block diagram, but also in the schematic, it can be seen that main audio (UAFA) is connected to V-IN-Left and sub audio (UAFB) is connected to V-IN-Right of the USB audio codec. Given all the “at the same time” features of the IC-9700, I resisted to believe this to be true. Some sources on the Internet mention that only main band audio is output via USB. Since it has a stereo USB audio interface build in, it’s logical to expect the IC-9700 to output main and sub band audio at the same time over USB as well.
In DV mode, it can decode two digital signals at the same time, something even the IC-5100 cannot do. Icom’s new IC-9700 can receive two bands at the same time.
