[Kenwood] TS-850 Question

2003年3月25日 23:06:34 -0600

Levent,
Clif is right. If you really want to know what your p.e.p is, buy
a good quality p.e.p. reading watt meter. I'll keep my opinions about
MFJ to myself. Spend some money. Also remember that you won't get
the output from your solid state rig that you will out of your TS-830S 
tubes.
