Ok. On the trip now. I brought them both. From the eighteenth floor with wireless and all the other noise the 817 is useless. The ts 50 has been alright. Worked Russia. Canada. Italy etc. Lots of antenna experiments. Works best with a 15m dipole as a sloper. Will try the ts 50 with 10 watts but not promising. I bet if I carried the 817 to the beach id do lots better.
Indeed you will, QRP and a decent vertical from the beach is fantastic, I speak from experience with this as a lot of my backpack and QRP DXing is done from the beach area, truly unbelievable distances can be covered with very little power, of course timing and conditions not withstanding
