Technical features : Hardware: AT-Mega 2560, TFT display 480 x 320 &. Encoder Software: CAT991A.hex file. The interface with the transceiver is via the RS232 port. With the settings menu it is possible to vary the frequency of VFO A, the frequency of VFO B, select the band, set the shift of VFO A, the shift of VFO B, the modulation mode and set the transmission power: it is also displayed the S'Meter bar, the set power and the SWR. The power supply is 12 Volt DC and via the 7808 equipped with a small heat sink it also powers the Arduino Mega board.. Description : By rotating the encoder you select the item to be set then press the encoder button to modify the selected item. The + and - buttons are used to scroll the cursor to change the appropriate value. The Ok button, in addition to returning to the settings menu, saves the values in the EEPROM . |
