Hi Remi

I was indeed missing something! And missed that article thanks for the
pointer. What a crazy set up only the EU bureaucrats could dream that one
up. Still I have no plans to change till I have to in 4 years time and by
then it may be sorted out.

Regards

Pete

Pete,
I thought it was as simple as that before I read an article in the May 2013
issue of the Light Aviation magazine. You must transmit/receive on a given
frequency in 25kHz mode or in 8.33 mode depending on the mode used by the
ATC unit for that frequency. Let's say the required frequency is 130.025,
the radio will transmit/receive on 130.025 on 25kHz mode. Now dial 130.030,
the radio will transmit/receive on the same 130.025 but on 8.33kHz mode.
Crazy, isnit ? Now dial 130.035 and you will transmit/receive on 130.0333
(130.025+8.33) on 8.33 mode. Dial 130.040 and you will get 130.0416
(130.0333+8.33). Next frequency will be 130.050,  and so on....

[quote]  Am I missing something here? Why do you need to switch modes to
work in the 25 spacing? Does not the 8.33 spacing simply provide 2 extra
frequencies in 
the gap between the exiting 25 spaced ones?
