okay I did a lot of reading of the manual - but this is still not quite intuitive.? must I set the QCX for WSPR operation before plugging in the GPS?? could this alone (along with an open circuit on the antenna port) explain why I nearly had smoke coming from the QCX when I attached the GPS?? not sure I have plans yet to use the QCX on WSPR - but since I installed a connector for the GPS - I am curious enough to get it working before I put the QCX back into its case (it was out to install L5 for the mod).?
just in case I decide to do WSPR - I should look to see if I have a metal slab to install as a heat sink - I remember doing this once on a rig - maybe the Fort Tuthill - where we used a thin layer of epoxy to attach it?? anyone else have a suggestion to improve thermal??
someone seriously needing to use the QCX for WSPR might wish to implement a drive control if it is possible (or reduce the supply voltage).? curious if anyone has done something here.?
enjoy your radiations.?
