Nice portable station! What kind of run-time do you get from that battery?
why do you like tube instead of transistor ?
Hi N0XLT, unfortunately i underestimated the battery size completely. I should use at least a 40 A-h battery. Instead i tried to get away with a 7.5 A-h in attempt to run QRP. This battery only supports receiving operations, where the IC-725 draws 1A on receive. I suggest lugging a huge battery along with you or getting a pair of jumper cables to run it off your car battery for portable ops.Hi 9W2PJU, I like tubes because i find it interesting to work with both new and ancient technology. I believe that engineers and experimenters should be able to design with tubes, transistors, modular IC's, or up to high-level sub-system modules. It is more of a part of my philosophy on engineering rather than a sound thing, but, certainly musicians prefer tube amplifiers in practice (such as guitar players). I am hoping to performa double-blind sound test with the tube amplifier at some point in the future, stay tuned.Thank you for your comments,Greg
