On 2nd...4th of September i will be in France again, transmitting on 137 
kHz from JN29OD96TK <http://no.nonsense.ee/qthmap/?qth=JN29OD96TK>
I will use a 200m vertical antenna (if i get the permission from the 
french OMs), a good earth and decent TX power. Since my RX has a 50 Ohm 
input now, i will check how the TX antenna performs as a RX antenna 
(having a 3/10/13/20/23/30/33/40 dB attenuator in line).
But i rather expect the loop will outperform the vertical due to its 
directivity...
