ATC over T1154+R1155

[scoobie]

Hi folks,

I guess I'm too dumb to figure out how to work with these radios, so maybe someone can give a tip?

 

Have you ever been lucky talking to various ATC on the Channel map (single player)?

I can tune 4.0 MHz and talk to people at Hawkinge (where my mission starts) no problem. They talk back to me, clear for start-up etc., but when I'm later trying to contact any other airfield, High Halden, Manston, whichever, while I'm already in the air (for example to call "inbound") - they always remain silent.

There must be something I'm doing wrong. I just retune the transmitter and the receiver to the new frequency, isn't that enough?

 

Yes - I keep the "standard" A/B/C/D channel radio (TR1143, IIRC) OFF all the time, so it doesn't get in the way.

How do you select the T1154 to talk?

I’ve only seen a Morse key on the right side of the Navigator.

That's the one! The navigator's Morse key lets you talk to ATC
In the Controls window it's called "T1154, key button - press" and by default it's LAlt + \
On T1154 select "R/T." (which supposedly stands for "radiotelephony").

 

OK, I know it wasn't a very practical excercise, but I checked ALL airfields on the English side of the Channel map, one by one. I ran through the list given below twice, which means I had to tune each airfield from scratch twice - to reduce the risk of dialing in a wrong frequency (both times).

Same results each time, which may indicate there's nothing wrong with the radios in the Mossie (nor arcane about them, at least not voice comms), but maybe something wrong with frequencies/ATC on the Channel map.

 

If anybody (out of boredom, I suppose) cares to check and gets the same results, I'll report it in the Channel map forum. Or maybe someone can test French airfields?

Here's the sequence in which I attempted to contact specific ATC. All frequencies in MHz.

 

Hawkinge 4.000 OK

Detling 4.050 OK
High Halden 3.800 no reply
Headcorn 3.825 no reply
Lympne 4.025 OK
Biggin Hill 3.850 no reply
Eastchurch 3.775 no reply
Manston 3.975 OK

 

P.S. Yeah, I know it's not THAT important, but I found it kind of sweet that Mossie is the first warbird in which you can talk to just about anybody, you're not limited to those 4 preset channels.

I reported an issue with not being able to "back-tune" the TX using the RX.
The specific frequency I had issues with was 3.825 MHz as it's not an easy to find position on the TX, but easier on the RX.
That was at Antonio B. Won Pat International Airport on the Marianas map, so it may not be map specific.

As a sorta workaround, you can use the preset wheels on the transmitter to set some of the more challenging frequencies. You put them in the ME, then switch from FREE to the desired letter and rotate the tuner dial until it clicks into place.

We got a winner! Thank you  @The LT, the idea with presets helped solve the puzzle. I reported it in another thread.
So, basically... two facts:
1. In the "few MHz" band English ATC people actually do talk on the frequencies given in F10 map. (I tested in MiG-15). Haven't tested the French, but I assume everything should be fine.
2. You can't contact stations at around 3.800 MHz, because if you set the transmitter to around 3.800 it's simply not that frequency. The transmitter actually "talks" 3.800 when it shows 3.700. Go figure.

So, case solved (and bug reported). Thanks!

No problem, I can also confirm this. I was a bit puzzled with it myself at first but you confirmed my suspicions.
