zika1234 Posted January 10, 2009 Posted January 10, 2009 Hi to all, i have question? How to use emergency radio? I switch it on, and even input emergency radio freq manually, and i dont get any answer when asking for azimuth to base? And - is there a posibility to use VOR stations for navigation?
Frederf Posted January 11, 2009 Posted January 11, 2009 The Ka-50 does not have a VOR reciever, ADF only. There should be a "guard frequency" (loose translation) switch on the VHF2 radio panel at the front left. I haven't tested if places actually respond on this frequency or not though. I'll give it a shot on the next flight.
zika1234 Posted January 11, 2009 Author Posted January 11, 2009 Well, i switched it to on position, but i dont have contact with tower
Frederf Posted February 1, 2009 Posted February 1, 2009 I figured out the problem with the emergency frequency!!! “АП” (Emergency radio receiver) switch. When placed in the up position, this places the radio in a fixed emergency radio receiver frequency, used to receive emergency signals. In the western world, this may be viewed as a guard channel. When activated, the frequency automatically switches to 121.5 MHz and the transmitter is turned off. [LALT + LCTRL + E]
Frederf Posted February 1, 2009 Posted February 1, 2009 (edited) Air-to-air VHF radios in Black Shark are typically done strictly on 127.500 MHz so the whole concept of different frequencies is really wasted. If you wanted to get 2 separate datalink rounds going (say 6 to 8 Ka-50s on 2 datalink groups) then it might make a handy "listen to the other channel temporarily" switch. That is of course if DCS did human voice over radio channels, which it doesn't. I don't know if the emergency tranceiver is capable of data traffic. I guess in real life you would avoid 127.500 for all normal radio traffic and use it strictly for emergency situations such as a distribution of emergency information. The R-800L1 radio actually has 2 independent tranceivers (normal one is tuneable, second is hard-wired to the emergency frequency) so failure of the normal radio would allow you to at least recieve over the other one. EDIT: I guess you could use the ADF/VHF2 slaving to have a stealthy way to receive a bearing to a 127.500 MHz transmitting station without the danger of accidentally transmitting. I don't know if the emergency transceiver does the ADF slaving though. I'm still learning more about the radios and I still have questions myself like: 1. Where the heck is the volume knob for the VHF-2 radio!? 2. Why can't you adjust the frequency tumblers with the mouse wheel? 3. Why don't we have a transmit button so we can at least use the VHF2/ADF feature to act as flying NDBs? 4. What is the AM frequency range? Edited February 1, 2009 by Frederf
