Apache radios issue

[markturner1960]

Hi, been figuring out adding some authentic chatter on 2 frequencies in a mission for the Apache. Having some issues that I suspect may be more module related as opposed to not doing it right. I have been getting help in the mission editor section, but seeing as now it may be something Apache related, I am asking here to see if anyone can help. 

Basically, ME transmissions on specific freq's can be heard without tuning the radios to the required channel and then they loop on top of themselves. 

Original thread with more detail is here, with relevant information for this query at the end: 

Are there any known issues with radios synching between front and back seats for example?

I took a look at your mission and I think it's a weird area where the trigger related radio chatter isn't matching with how it should work. Basically, it appears that both the FM radios are getting overlap on the frequency set (30FM), even if you manually tune one far away from the other. However, this only applies if you're using the trigger with radio transmission attached to zone; when used with a unit transmission, it works as advertised (with a narrow band where you can get some overlap, ie ~0.05MHz separation). If you tune both FM radios to the 30FM frequency, the issue seems to go away. It also goes away if a unit transmission is used in place of zone trigger.

Awesome, thanks Needz, will alter as suggested

Hi Needz, well, not sure what I have done wrong, however, I deleted the 2 triggers I was previously using. Then, for the ground chatter I set the JTAC humvee to transmit a message on 30.00 AM as an advanced waypoint action and chose the same sample I was using previously. Then I did the same for the air chatter, on 124.00 AM ( By the way I tried using AM and FM for both and neither worked) using one of the AI Apaches. I could not hear any transmission when I tuned the radios to those freq's. Could I trouble you again to look at what I have done and put me straight? I have uploaded here, again with the test samples rather than the actual chatter audio, which make the file too large to post

So the first thing is that the unit you have set to use 30 is on AM, not FM; the second is that you have that JTAC unit with FAC assignments which override the transmission command. However, I did find that the hot start slots seem to have an overlap with the FM radio frequencies by default -- unless FM2 is used exclusively. When I modified the default starting frequencies, the problem went away. So there's a bit of column A, bit of column B going on here. The cold start spots worked as advertised with no issues (once the JTAC broadcast was corrected). My interim advice would be to modify the starting default frequencies for the FM radios on the hot start spots (they use preset 3 and 4 by default) with at least 0.1MHz of separation between frequencies, as the defaults of .005 are insufficient to stop interference.

I'm attaching a mission with all the radio systems tuned to receive custom transmissions, which should help guide you, whether using a scripted transmission, trigger zone, or unit transmission.

Also, keep in mind FM is very prone to interference and LOS issues, so the transmission can be spotty without a very clear LOS.

Great, thank you. Will take a look at this tomorrow morning
