Thanx for your reply. However, the manual states that the frequencies are set using the R-800LI.
"R-800L1 VHF Radio Control System The R-800L1 is a VHF-2 command radio system. The radio system is turned on using the VHF-2 (“УКВ-2”) switch on the right panel. This radio can be used to communicate with other airborne units and provide reception of ADF signals."
Further down it states...about the ADF switch on the radio.
"4. “АРК” (ADF) switch. When this switch is moved to the up, on position, the radio is used for automatic direction finding (ADF). The radio compass antenna is then connected to the R-800L1 radio receiver, and the receiver controls radio compass antenna direction (this in turn controls direction of the HSI RMI arrow). The HSI RMI arrow will now point in the direction of the transmitter with the frequency that is defined on the R-800L1. [LALT + LCTRL + A] A complete list of available ADF channels can be viewed in the Automatic Direction Finder (ADF) ARK-22 section of this manual."
