[TenTec] Jupiter Question?

[Gordon Jacobs]

 I have recently acquired a Jupiter. When I push tune I only get about 20 watts. The output meter reads 23% Which is about right if the radio puts out 100 watts. When I try to modulate it the out put meter says 102%, but my old wattmeter will only show about 50 watts. I have tried this with 2 different watt meters and they are the same. Is this normal or is there something wrong, or is it the operator?  This radio may be more than I can get my old mind around! Gordon KA5ZTI
