Re: Can FT-847 power 2 preamps with total current of 400mA


 

Hello.
Sorry, but I don't?understand?why you may be looking for trouble?connecting the DC supply of the AR's LNA's to? the FT-847.
I can tell you that after 6 months of working on a faulty FT 847, that it's an? old radio, not enough technical support and a shortage of obsolete?spare parts.

Isn't it simpler to use an?external power supply?

I just acquired a used FT-847 and plan to use it for VHF/UHF work including getting into satellites. I have one question. I plan to get preamps and am looking at 2M and 75cm mast preamps from Advanced Receiver Research. They require 200mA each. The Yaesu manual says it can supply 300mA to the VHF AND/OR UHF connectors. I am confused if this a total for both connectors conbined or 300 mA each? Looking at the schematic I see there is one current limiter for both connectors so I assume this is a total number. I am wondering if anyone has run into this?

Thanks,
