My nearly new Garmin SL30 which has previously worked fine, today in the air
started refusing to change frequency. It was as though it had decided to
stick to just one working frequency and just one standby. Changing the
standby saw it change back to the starting one over the next second or two.
Changing from the active to the standby was followed by it changing itself
back to the previous active. This is a potential disaster as I am due to fly
off to the Black Sea (fortunately the West bank of it!) on Wednesday, and
the avionics experts at RGV Aviation are off on holiday.
The SL30 is linked to a Blue Mountain Efis to display VORs & glide
slopes, and potentially to share frequencies, but the radio behaved the same
when I switched off the Efis.
Any thoughts would be most welcome
Regards, David Joyce, G-XSDJ
