Re: [Amps] Ameritron ARB-704 - Photos and Schematic

[Charlie <ad5th@direcway.com>]

ICOM support never answered my email but when I called them up they 
definitely said to use a key line buffer or expect a failure. I do not know 
that the ARB-704 is any better than the buffer you already have.  The ICOM 
tech did mention the ARB-704 as one that he knew worked with the 746 Pro.

To answer your question I don't think your missing anything. There are 
several key line buffers out there..some expressly for the Icom line and 
others like "Amp Keyer" and the ARB-704 claim to work with "virtually any 
rig/amp combination"

-ps my ARB-704 is working fine...now I need the Somalia station!!

Trying to learn something here. i really do not understand the need to buy 
the 704 box. Please let me know what I am missing? As far as isolation I 
bought a $18.00 9I think) off Ebay. have the solid state relay built in to 
isolate my 756 Pro II from my Ameritron 811H .

The 704 looks great am I missing somethign do i need to upgrade to the 704? 
Even though Icom support advised i needed nothing I checked with this group 
and was advised to isolate the radioa nd the device I am using works great 
in doing that.
Thanks.  If there really is a reason I may have to look at it thanks
Dan
