Amazing, works like a breeze!

"ERROR: Detected 'ipw2200' or 'ipw2100' for interface eth1; This driver
will not change channel using mac80211 commands in most cases.
Kismet will use legacy channel control commands."
... and no further setchannel() errors.

Many thanks for your quick help, greatly appreciated.
