wess24m Posted May 5, 2013 Posted May 5, 2013 The NDB at Batumi airport and the ADF will give you an initial NDB audio beacon code once then nothing. When switched to ANT it plays continually like it should but (because the ANT isn't intended to be use with the radio compass) you get no directional information. I've tested with other airports equipped with NDB and I get the same results. When switched to either look settings you also get audio from the beacon, just not when on the ADF setting. To be clear, you get directional indication on your radio compass but no audio (aside from the one time when you initial tune to the station) from the NDB beacon.
Flyingfrog Posted July 17, 2013 Posted July 17, 2013 BST, I got same issue. Looks like the "automatic gain regulator" (agr) is wrongly setup. For the moment, as turn around fix, I use "ANT" to confirm morse but would be nice to fix this. I'm nut sure but in reality, does the ARN83 has a autogain built in? tks
-MadCat- Posted July 18, 2013 Posted July 18, 2013 Thanks for the info ! I had a look through the "Organizational Maintainance Manual" for the AN/ARN-83. And if I understood everything alright, this should sum it up nice and short. Chapter 2-2: "[...] In any operating mode, the direction finder set will provide an aural output of any audio modulating the radio station rf carrier. [...]" For every submode (ADF, ANT, LOOP) there is a note to adjust gain volume to a comfortable level, if desired. So the set should always give audio to the headphones. Yet I cannot find any information about an automatic gain control in said manual. Will post this in the bugreport too.
