Hi,



I imagine someone on this newsgroup can point me in the right direction on a

technical/FAA question.



Becker offers 2 versions of their AR6201 radio. The original version has

frequency spacing that can be set to either 25 mHz or 8.33 mHz. The new,

slightly lower cost option has frequency spacing fixed at 25 MHz It is my

understanding that the 8.33 MHz spacing is required in Europe, but not

currently in the USA. Customers are asking me whether the FAA has any plans

to go to the 8.33 MHz spacing in the near future - so they can be better

equipped to select the radio version that makes sense. At a recent soaring

seminar someone stated that they thought the FAA was going to require radios

with the 8.33 MHz spacing starting in 2020.



Can anyone help me?



Thank you in advance.

Don't know about the FAA, but the FCC permits some use under Part 87. Haven't found a mandate, yet.
