Attaching a Transponder to a Unit (MIST)

[dwpenney]

Hey guys. I had this working in DCS about a year ago. That was a much older version of DCS and a different version of MIST.

 

My problem is that either the code I have is not working in the newer DCS/MIST or I just can't tune the frequency in correctly in the Huey. It could be the latter, or a combination of changes in the Huey that is making this not work.

 

So the code I had was this (please excuse the typos as I am modifying the original code to have as few variables in it and therefore, hopefully, improve it's readability):

 

position = Unit.getByName(src_unit_info.spawned_unit.name):getPosition().p
transponder_freq = 250000
freq_txt = "" .. (transponder_freq / 1000 ) .. "kHz"
temp_id = mist.scheduleFunction(
trigger.action.radioTransmission, 
{"VHF_WarningTone.wav", position, 0, false, transponder_freq, 1000}, 
timer.getTime() + 10, 15)

 

Now this worked. The .wav was included in the .miz file and I was able to start the Huey, turn the ADF to the frequency, see the signal strength indicator spike and head the wav (morse code) with the proper setting on the ADF.

 

Now, in the new DCS/MIST, I have the following code (please excuse the comments interspersed in there as I was trying to make sure I had everything lined up):

 

 source_position = Unit.getByName(val.unitName):getPosition().p
source_freq = 250000
temp_id = mist.scheduleFunction(
-- Function
trigger.action.radioTransmission, 
-- File Name, Vec3 position, AM|FM, loop?, freq, power
{"VHF_WarningTone.wav", source_position, 0, false, source_freq, 500}, 
-- Time (now + transponder_delay)
timer.getTime() + 10, 
-- repeat every n secs
15)

 

Am I missing something obvious? I have a lower power in the second code block, but I am within a couple of km of the source position with the Huey. I get a signal strength indicator but I am hearing no sound. I added a function call to play the sound at the start of the mission just to make sure that it was found and sounded like it should.

 

Any suggestions on how I can trouble shoot this with a different aircraft (in case it's the Huey)?

i know the CTTS.lua (COmplete Transport Script) has some working elements for Radio beacons. Have a look at it in the Scripts library ... its the one by Geloxo.

 

Mind you, i would be interested in a solid process from within MIST if one could be found. Unfortunately I can only beg borrow and steal script code from those smarter than i... i can't help on th e troubleshooting front.

I try to get something like this to work in my mission too. Can anyone help ? i need to get FM transmission to go when blue side pilot is ejected and landed on ground ? so players can save them using hueys fm homing :helpsmilie:

That's exactly what I am doing in my script. On an Eject event, spawn a downed pilot (because I can't seem to access the one DCS generates) and set a transponder pinging from that pilots position with the above code.

Thanks, can i use your script ? :)
