Perhaps this controlled carrier modulated transmitter would be a good
mate the the SDR-5000. It is limited to 100% modulation. Would not cover
all ham HF bands however.

Hi All,
The beauty of SDR is that we have the RF signal in digital form.
In this discussion of AM detect algorithms it could be very
useful if those of you who observe signals that are not
detected well would make raw data files available.
In case a bad audio quality is observed with a

For those who want the best fidelity from AM, the problem is this:
The carrier gives an almost perfect reference for receiver AGC,

For many years now on the short wave bands broadcast stations have been
using CCM (Controlled Carrier Modulation, also being called other names)
to reduce the carrier as much as 6db. That along with multipath can
cause some strange distortion problems on the receive end. That has as

I gave up on am broadcast. There's too many stations on the same frequencies.
All I hear at night is a cacophony of overlapping interference on every
channel.

I believe you mentioned the same, or similar problem, on AMfone.net, back
around January/February 2010, when you still had the 5000 and were
running version 1.16 or 1.18.

Which version of PSDR are you using Brett? Version 2.2.3 fixed a very
big issue with AM reception (AGC tracking the sideband energy rather
than the carrier energy) that was present in all the previous 2.x.x
versions and the later 1.x.x versions. That being said, I do notice what

Running here PSDR V 2.2.3 with Flex 5000. The only time I occasionally
hear some type of peak distortion or muddy-type distortion on 75 meters
is when listening to strong AM signals operating class E type rigs. I
don't hear on it on broadcast AM, commercial SW AM, or amateurs running
current

Hi Brett and All,
Mostly on strong AM ham transmissions on 80 meters, the homebrew receiver is
clear, the 3000 is nasty.
I do not remember anything like this on the 5000 I had a few years ago.
I think I would like to go back to an older version of psdr which seemed to
work better for

I don't remember having any problems with AM reception on the old version.
