All,
I talked with Rob myself prior to Dayton. A common problem with AGCs is
that the AGC control voltage is developed after the IF filtering. This
limits the AGC response time (on attack, is the issue) due to the narrow
IF bandwidth. When a large RF pulse comes in, its envelope can rise

Jim,
Problem #1 has little to do with the preferred quality of sound or
analog vs digital. Its about blocking out a weak signal when the AGC
responds to a very rapid rising, short pulse. It happens that some of
the newer DSP type radios have a AGC algorithm that trigger off this
short pulse. It
Jim,
We have a built-in interface for VAC in PowerSDR that will work for Vshaper
just like other third party digital mode programs. The knowledge base has
several articles with details on how to set this up.

I'm trying to use vac to insert an audio processor (vshaper) between the
fa66 and sdr1k. For some reason, pwrsdr won't even let me start by calling
the fa66 "unsupported" and copying the settings.
I really think that I'm barking up the wrong tree (to use a good southern
expression) and would ap

Hi
Can someone tell me the current ratings for the Atlas platform using now
Janus and Ozy and later further boards. I would like to build a Linear PS
containing all the voltages. Sure I can use a ATX PS and measure all the
current ratings, but maybe somebody gone the same way and tell me.
Please

Seems that he has two problems:
1) the implementation of the AGC algorithm in commerical radios using
a DSP. It's different than what you'd get with a tradition

Any clarification on use of vac to play with the audio between an FA66 and
the sdr?
At first glance, the FA66 almost seems to be built to work on the sdr and
refuse to talk to any other software!! Not really, but it does appear to be
a bit different.
Anybody have the plans for the wheel here? I
