PostForum: AM transmitters   Posted: Tue Nov 01, 2005 3:59 pm   Subject: AM MAX II MODS

I thought it required about 50 watts as well but testing proved otherwise. The gain of the amplifier seems to be computer controlled and it has the ability to adjust the gain it delivers depending on ...

PostForum: AM transmitters   Posted: Mon Nov 15, 2004 4:11 pm   Subject: Amplifier with AM Max II
I have used an SGC SG-500 amplifier which provides a 200 watt carrier from the AM Max II using the 19 volt power supply with about 7 watts output. With modulation peaks I recorded an output of over 5 ...

I just received my AM MAX II modified for the 6000-7000 range. I ordered the 19 volt power supply from PCS as well.

I've done very little testing so far but first impressions include: Very clean l ...
