NOTE: Cover the type-N connector with self valcanizing tape to avoid water seeping into the unit. Binding the type-N connector with self valcanizing tape increases the waterproofing of the connection mold. ï Before setting Test to operate on the ground before installation is recommended. (See the figure at left. ) w Turn the IC-910H power ON. · Push [M/S] to set the 144 MHz as in the MAIN band. s Connections Satellite communications via the AO-40 can be made when using the IC-910H satellite function mode and the AG-25. For satellite communications, an antenna rotator which adjusts the antenna direction (azimuth), and an elevation angle rotator which adjusts the angle above the horizon, are necessary. · Connect AG-25 and IC-910H e Push [SSB/CW] to select SSB or CW mode. to turn the AG-25 power ON. · When the AG-25 functions correctly, the noise level rise up. 2400MHz band AG-25 ï Orbit information Orbit information describes satellite location, wave angles, etc. · Push [SWP 0 S ] again after the tuning.

MEMO LSB SATL RE V S1 3 5 7 9 20 40 60dB NOTE: To select the operating mode for the uplink, push [SUB] to enable the SUB band access. · Refer to a ham magazine or book for detailed information. · Adjust the antenna direction so that the S-meter shows to its strongest level. · The S-meter level should be noted for transmit power adjustment during a loop test. u Perform a loop test. · Set the downlink frequency (MAIN band) to a vacant frequency within the satellite's coverage. · Push [SWP 0 S ] then, set the uplink frequency (SUB band) while transmitting a single tone such as a whistle to find your downlink signal and monitor your own signal correctly. Push [SWP 0 S ] after setting. w Rotate the tuning dial to re-tune the downlink frequency after pushing [SCAN . M ], when the operating station's signal frequency is shifted. · RIT function can also be used for downlink frequency tuning within ±1 kHz range. s Satellite memory The AG-25 has 10 satellite memory channels to memorize both uplink and downlink frequencies and operating modes, etc. USB P.
