Re: 136.600 for ARINC in USA

Kevin Elliott

Thanks Dan! This lines up with what I knew. I appreciate it very much. Been using those three with vdlm2dec for about 8 months. I’ll have to add the other two.

Side note: I’ve been working on an aggregation service for ACARS/VDL for some time now, and have had quite a lot of success receiving VDL (in some cases much more traffic than ACARS). It’s still alpha, but if anyone is interested.

What are the 5 US freqs now?
Hi Kevin,

The first three are very active.

136.650  ARINC only
136.800  SITA only
136.975  Primary (both ARINC and SITA).  International freq.

136.700  Was added last November 2019.  Little to no traffic, but at least one GSIF confirmed.
136.600  ARINC only. Just added June 2020.  Only one license so far I believe.

With dumpvdl2 it is just as easy to monitor all 5 frequencies as it is one.  Monitoring all 5 puts very little load on even a minimal CPU.  Sergio is very good at tracking license data.  He discovered both 136.7 and 136.6.
