Backup UHF radio and player/ai Tacan
-
G’day gents,
1. Can someone direct me what are the frequencies on channel knob on backup radio 1-19, are they set from DTE too? Can’t get it to work
I know that something is mentioned that they are diiferent, but can they be set somehow or are hardcoded and drop all thing.2.It is said that player can select his transmitter tacan channel (ai cant) but how?
Is it derived from modem transmitter id then +/-63 or? and, how to set transmit band x/y?3. also , In the “old days” of AF and maybe others,… ILS freq, if any, of given Tacan was automatically selected, probably from stations.dat.
In BMS this is not th case, is it by design or do we have to type in manually too?Thank You

1. it’s explained in the manual. you can see the preset frequency in the DED as you go backup mode on the CNI. the bup channels and assigned frequency are visible on the ded.
It’s also been explained on the forum if you make a search2. more info required AA? AG? Once again, all that is explained inthe dash1
3. explained in dash 1 as well. It works as in real life. tacan and ils needs to be separately tuned in to work
Please RTFM

I know that something is mentioned that they are diiferent, but can they be set somehow or are hardcoded and drop all thing.BMS manual -1, section 1.2.1.14 Backup UHF panel, page 24:
The channel knob selects one of the 19 presets available. In BMS those presets are fixed and do not correspond to the ones set into the DTC. By default the panel selects channel 6.2.It is said that player can select his transmitter tacan channel (ai cant) but how?
BMS manual -34, section 1.3.2 Air-to-Air Modeling, page 32-33:
A-A TACAN is a little bit more complicated than A-G. The channels between the two coupled aircraft need to be 63 apart. The maximum allowed channel is 126, one way or another. So if you want to tune into another aircraft that is on channel 11, you need to input channel 74 (11+63= 74). If the other aircraft is on channel 80, you will have to set channel 17 (80-63= 17). You can’t set 80+63=144Y as that’s over the 126 limit. In A-A mode the band can be X or Y, but the mode needs to be set to A/A TR.
[…]
While humans can select any channel and band, AI (Artificial Intelligence) aircraft use fixed TACAN channels in the Y band. AI first flight is set on 12, 22, 75 & 85Y. The next AI flight is one number higher: 13, 23, 76 & 86Y. The BMS code can support up to five flights of AI with this system. That means that you can always find an AI controlled aircraft in the first 5 flights.Is it derived from modem transmitter id then +/-63 or? and, how to set transmit band x/y?
BMS manual -1, section 1.3.5. T-ILS page (1), page 63:
To change the TACAN from T/R (ground domain) to A/A TR (air domain) use the DCS SEQ button.3. also , In the “old days” of AF and maybe others,… ILS freq, if any, of given Tacan was automatically selected, probably from stations.dat.
In BMS this is not th case, is it by design or do we have to type in manually too?IRL you need to type that in manually. You can set default ILS & TCN channel in DTE (manually in callsign.ini or via WDP)

Thanks for the answers. Red dog, Focaldesign, …
I’ve been doing RTFM since the AF / FF Red Viper/OF/ BMS, so, no offense, it is more “no english my native problem”
and some of this this is new, specific to BMS. I’ll try to be more clear now@Red:
1. it’s explained in the manual. you can see the preset frequency in the DED as you go backup mode on the CNI. the bup channels and assigned frequency are visible on the ded.
It’s also been explained on the forum if you make a searchAwww, neat trick, never come up to that, DED UFC BUP …… ah well mate. Thank You , all good, solved …
@Red:
2. more info required AA? AG? Once again, all that is explained inthe dash1
Yeah, well, I thought it will be hard to explain
… It is for AA Tacan between eg. human players… 11,12,74,75 …X/Y .There is no problem in RECEIVING of Tacan in UFC or BACKUP mode , that is old stuff , no problem here. The problem is in TRANSMITTING of your own channel to the other eg. human players.
I’ve read (maybe comprehended wrongly ?) in the manual that human players can SET his OWN transmitter channel. , @BMS:
So lead sets an A-A TACAN of 10Y and transmits that information to his flight members.
Well how do you set “10Y” to your plane ?
There is only DED IDM page where you can set your XMT ID , is this related to calculation of tacan 10+63=73 ? , I think it is…If yes , how do you set YOUR TRANSMIT TACAN BAND X/Y ? , I cant find that option.
@Red:
3. explained in dash 1 as well. It works as in real life. tacan and ils needs to be separately tuned in to work
Ok, manually then. no prob. , I’ve learned the hard way , didnt work for me until I’ve input ILS freq manually.
Ah, FalconAF is to blame, some thing were simplified there.Cheers and Thank You

But I’ve read (maybe comprehended wrongly ?) in the manual that human players can SET his OWN transmitter channel. ,
How do you set that , in IDM DED page. “xmit 10” or ?
ICP: “1 T-ILS”, use DCS 4-way switch to put the scratchpad on the TCN part if not there already by default; push 1-1-enter to set 011. Push 0 enter to change X to Y. DCS switch right (SEQ) to toggle T/R to A/A. Done. Your wingman does the same but +63; so if you have 01Y A/A, your wingman needs to set 64Y A/A

So this is TRANSCEIVER … awww… not just receiver
That was the "human"error, all this time I thought that T-ILS was only receiving side.Well ok , yeah , even that means that we cant be tuned to 2 different Tacans at the same time … eg Receiving 74X TR , and Transmitting 10Y AA-TR.
But we can set one in Backup , other in DED T-ILS and easely switch between .Thanks, thanks, thanks
One more question tho, can you TRANSMIT also on Backup Tacan? … I guess yes, it is the same code, just the switch …
-
Yes if you use the relevant switches on the AUX com panel (left side)
AATR/ TRAlthough it’s age since I did that, so consider it untested

Solved

F-16 has TACAN TRANSCEIVER !!! Very interesting info!

Of course, two-way communication is required for the DME component. If you change TACAN equipment to receive only you will lose distance info but keep azimuth (if there was azimuth capability in the first place).
