Thanks for the information Gould.
Will you clarify, please, that TXA is the normal U/V configuration - and also that these are the power levels we can expect for Field Day? That's what I understand from your comments.
Thank you, and thanks for all your efforts to keep AO-51 functioning as best as it can given the issues you have to address.
73 to all,
Tim - N3TL
