Swift Client: text mode communication issues with some US controllers

[Jean-Luc DUMOULIN]

Hello to the staff, hello to all

For more than a year I have been using, on the recommendation of VatFrance, the Swift client to communicate on the Vatsim network. This was going smoothly until now when I was flying in US airspace.

For several weeks, I can no longer communicate on the frequencies indicated by the air traffic controllers in their overflown spaces. This only concerns US controllers, everywhere else Swift works perfectly fine.

Is this problem already known and do you have a solution for me to solve it?

Cordially

Hi Jean-Luc,

I suspect the issue lies with controllers using a channel with 3 digits after the decimal where the third digit is sometimes a "5", e.g. 121.725. For historic reason the third digit is ignored and set to "0", so clients may connect to text-channel 121.720, in the example. On your next flights, can you please test if this problem also exists with controllers that are using frequencies that have an official "0" as the last digit, e.g. 121.750 ? Does the problem exist on them as well?
