1. [Amps] SG-500 ALC Interface to Kenwood TS-480HX (score: 1)
Author: Larry Dighera <LDighera@att.net>
Date: Mon, 25 Jan 2016 10:46:28 -0800
Given the SG-500's ALC control signal is +1 to +5 VDC, and the Kenwood TS-480HX's ALC signal expects -7VDC, how have others interfaced these two pieces of equipment? _________________________________

Interesting thoughts, gentlemen. Thank you. Fortunately, the SG-500 does provide drive attenuation when necessary, so ALC isn't actually required. I was just wondering if anyone knew of a circuit tha

The amp looks good from the CGI images, but it is what isn't said/shown that is disturbing. Why is the image of the "Revolutionary" user interface so small as to be unreadable? Although implied, I fi

Hello Christopher, Thank you for your response to my inquiry. I failed to mention that I intend to use the SG-500 in compressed voice SSB mode, so it should draw about 40 amps with a 40% duty-factor.
