[Amps] ft-2000 vs pgxlA couple related questions for both Yaesu and amps guys.
Just had to send pgxl back for replacement of an ldmos. They say onepossible
cause of ldmos failure is not allowing for at least 20msec betweenptt and rf,
which I thought I had set. but maybe not when looking at it indetail.
generating ptt through winkeyer which has settings at either 30 or50msec from
n1mm logger so that 'should' cover modes where n1mm or thewinkeyer generates
ptt I hope. But what about ssb vox? Is there somesetting I can't find to
delay rf there? Or will that always be longerbecause of dsp and af-if-rf
chain?? The pgxl provides for ptt-in and a ptt-out that isn't asserted until it
isready for rf, that should add safety to all modes except using ssb voxunless
there is a way to interrupt the vox to ptt internal conversion in theft-2000.
has anyone found a way to do that?? Does anyone make a device to measure ptt to
rf delay time? I know I can doit with a 2 channel scope using an rf tap. but
it would seem like a nicesimple device to take ptt and rf, pass them through
samplers and measure thedelay from ptt to the rf envelope start. David Robbins
