hi guys, need help please, do not know if it is a known bug: is impossible to set a manual frequency in the radio, i set the new frequence then hit enter, just click or keeping it pushed doesn't change, the new freq flashes but then it come back to previous freq.

The tacan and preselected freq work perfectly. Any tip?!?

Scroll COMM1 to Channel M (Really can use any channel you can modify), Enter frequency, Toggle UFC switch to ADF1. Same procedure for the other radio.

 

Tell us exactly the frequency you are trying to use, and tell us exactly which VOR you are trying to receive (map, 3 letter identifier).

i am sooo stupid, sorry for the trouble...i was trying to use some khz freq instead of mhz for adf...idiot newbie, sorry and thks for the help. In any case what are the khz freq?!?

Posted

sorry was my big fault, i have used adf for khz freq...i was looking at the map searching for freq to use for adf and did not pay attention to the fact that those where in khz. In any case where and when do you use khz freq??

Those are likely NDBs (Non-directional Beacons) and/or Inner/Outer marker beacons i.e. Batumi NDB "LU" on 430 kHz.

 

They are used for radio navigation / approach by some aircraft i.e. L-39, F-86, UH-1H, etc. but AFAIK aren't used by the Hornet.

Just for information purposes, Marker Beacons are fan beacons that transmit straight up. Their purpose is to alert the pilot when he crosses a specific point on the Localizer course (The horizontal guidance beam of an ILS system)

 

When a non-directional beacon (NDB) is co-located with a Marker beacon it is called a Locator Marker, usually the Outer marker.

 

If you see a frequency listed for a Marker Beacon, it is a Locator Marker as all markers use one frequency per type and are very low power and range. The frequency is the NDB portion of the Locator Marker.

 

All this stuff was necessary in the glory days before widespread DME and then GPS.

 

Most ILS systems had an outer marker, located at glideslope intercept and a middle marker located Category I minimums (200 feet AGL). Category II and III ILS systems added the inner marker at the lower minima point.

 

Of course, marker beacons could be used in other ways and in the days before ILS and in parts of the world with less than optimal navigation infrastructure, they were more common.

 

NDB's are being de-commissioned in the US and are pretty close to gone.

 

The nice thing about the NDB receiver is the ability to tune commercial radio stations and listen to the broadcast.

 

Many an oceanic crossing has been done by flying pre-planned dead reckoning headings until a strong commercial radio signal could be picked up and homed on by the NDB receiver.

How do you switch off hearing the morse code? Seems like the only way is using the volume knob of the radio itself. Problem is if you turn that all the way down, it completely switches off the radio. Any ideas?

Turn the TACAN back off, it you have turned it on an entered a valid TCN channel. If you have selected an ADF, toggle the switch on the middle left side of the UFC back to the neutral position.

I was talking specifically about the ADF. I've tried what you suggest but it doesn't work. The morse code is heard regardless of how the switch is positioned.

Automatic direction finding (ADF) is a mode of a receiver no matter which type.

 

ADF in the F/A-18 is a mode of the COMM radios. When you flip the switch to 1 or 2 it homes on the matching COMM frequency and displays bearing to station on the HSI.

 

When you flip the switch it automatically lowers the squelch to allow you to identify the station. One can re-engage squelch on the UFC (SQCH) but that will not stop you from hearing the Morse ID, only the static. The Hornet does not appear to have any method to select the COMM monitoring on or off, only volume control.

Did you tune one of the radio channels to the adf frequency? If so, change radio channel and it should eliminate the Morse Code, ya?

 

Sorry, but I have rarely used the ADF - so just trying to go off memory rather than muscle memory.

My assumption was that he wanted to continue homing to the station while not hearing the morse ID.

 

De-tuning the frequency will certainly end the morse ID but it will also end homing to the station generating that morse ID.

Yeah, I’ve become a bit confused as well. Seemed initially like there was a struggle to get the tone and direction - then seemed the struggle was to eliminate it. Either way, hopefully he got it sorted (lack of update on issue).

Correct.

 

The Hornet does not appear to have any method to select the COMM monitoring on or off, only volume control.

 

Seems like that's the case indeed.
