[Icom] Power meter on my 706 MKII

Sun, 20 Oct 2002 16:25:24 +0200

Hello Sasi,

I work with a 706MKIIG and I have noticed yesterday that my power on 160 and 80 is only 50 watts
in ssb. 100 watts in cw. I had more power before but I don't know what happend.

I hope you find what's wrong with yours !
