[Yaesu] FT990: CAT Data Structure Info

[wulf@ping.net.au]

Mike,

thanks for the quick reply and info. I workd around this and got a little
further. 

There is yet another problem that I came across that is bugging me.
It appears that sending the M>VFO command doesn't work

e.g. 0x06 0x02 0x00 0x00 0x00

This should copy the data from channel 3 into the last used vfo. All it does
on my rig is to switch back to the last used vfo when in memory mode or
nothing when in vfo mode.

The memory operations via CAT seems to be somewhat flawed. VFO>M and
VFO/M commands don't exhibit the expected functionality.

Can someone verify this?

Many thanks in advance,

73 Berndt
