[1] IRTS is the national member society representing Ireland in the International Amateur Radio Union.

[4] Radio in Ireland can be traced back to the 1800s with Professor George Francis Fitzgerald of TCD who in conjunction with Heinrich Hertz clarified and confirmed James Clerk Maxwell's mathematical theories of the electromagnetic field.

[5] This work led Fitzgerald to conclude in 1883 that an oscillating electric current would produce electromagnetic waves, which was experimentally confirmed by Heinrich Hertz in 1888 and used in the development of wireless telegraphy.

He held office for many years and was active in amateur affairs until the war brought a stop to these in 1939.
