Title: Mornings 7120 low power AM Post by: VE3LYX on November 13, 2012, 07:35:16 AM I will be on today wed and thursday at 8 am 9 am and 10am local time testing homebrew low power Am rig. It is about 20 watts input. I am using a carbon mic electro mechanical circuit so it will have that old military sound. Rig is a 50L6 screen modulated by 1/2 a 12sl7 (other half is the VFO) and is driving a 6l6 which is driving a paralel pair of 6l6EH tall boys. The triple 6l6 amp is link coupled to the exciter and output is fed through a link winding to a Pi style HD tuner Antenna is a 1/4 inverted L ( really a sagging slanted L but it loads well )
Any reports would be welcome. A Qso would be even better Don Ve3lyx Title: Re: Mornings 7120 low power AM Post by: VE3LYX on November 15, 2012, 09:28:15 AM I am starting to have some sucess here.
