Slightly OT I know but can someone advise me (since we are talking
airspace) - are transponders mandatory to carry and use in Class E
airspace in the US?

Transponders are required for all registered aircraft, if they were
manufactured with an electrical system.

Not required in Class E, G, or D or C

Unless under the Mode C veil of a Class B airport... i.e. if in Class E, G,
C, or D, but within 30 nm of a Class B Airport such as SEA, a transponder is
required unless you call the controlling authority (usually by phone) ahead
of time to make arrangements.
