Create a Nav 3 independent nav source

Do you guys plan to add an alternate nav3 source as some gauges need an
independent frequency that do not interfere with nav1 or nav2. For example the
Bendix 62A DME has it’s own built in tuner. June 8, 2021

Although for some reason I’m not finding it in the docs, you can already do
that in the sim using the following key events (it was a feature at launch):
K:NAV3_RADIO_SWAP K:NAV3_RADIO_SET K:NAV3_RADIO_SET_HZ K:NAV3_STBY_SET
K:NAV3_STBY_SET_HZ K:NAV3_CLOSE_FREQ_SET K:NAV4_RADIO_SWAP K:NAV4_RADIO_SET
K:NAV4_RADIO_SET_HZ K:NAV4_STBY_SET K:NAV4_STBY_SET_HZ K:NAV4_CLOSE_FREQ_SET
You can then use the standard nav radio simvars to get the data for those
radios, using indexes 3 and 4. -Matt | Working Title

I found out through Ben from Asobo and already have this setup. Did not know
you can go up to index 4. According to him only up to nav3.
