[Towertalk] 620/340

[Robert Cummings]

Hi Hugh,
When I contacted F12 regarding failed rivets in my 340 I was told

"Your experiences with rivets failing and the antenna failing apart is
so bizarre that it is hard to believe" and that came from Tom himself!

I presume I fell into the "Stupid Irish- they will believe anything"
category.
