[Mobile-Portable] Question about HF mobile

[W8WEJ]

put the rig in cw , key it and see what you get..
 
if you are actually getting 100 watts ssb pep out, it may well show(on 
your meter) a lower amount as the meter may not be indicating  the peak 
reading, but average  ..the real teckies can get in to this more
I would ground the rig with a good braid,,, short path,  make sure the 
antenna ground is good,,not a wire, not the antenna coax.. and see what 
gives.. you may well not have the problem that you think you have..
mobile is another world... but doable..and, lovable..after 52 yrs would 
not be with out it
good luck  73 john w8wej
