Re: [Flexradio] Audio Rack and the 5000

If your mic levels are wrongly set, you will hear it.
Otherwise, you will hear it if you have convinced yourself that it is there.

What problem are you talking about?  I certainly don't hear it?  Must be

Re: [Flexradio] Audio Rack and the 5000

[Lee Mushel]

Finally!I was beginning to wonder when someone would remember the very 
clear audio importance trail left by John Basilotto (SK)!   I once asked 
John why he was so concerned with audio and he explained that this was a 
special interest for him going back to prehistoric times and that explained 
why he was so concerned with audio quality.   Some early devotees will 
recall that the developing PowerSDR didn't always have the elaborate audio 
processing that it finally appeared with and John was the first to suggest 
that an audio processor might be something that people would want for their 
Flex5000s.   And he also brought True Audio "TrueRTA" to our attention at 
the same time.  I will admit that I have never used either the processor or 
the Audio software until now when I am going to start to see if I can 
develop the capability for emergency communications where I can walk up to 
the receptionist of the "served agency", hand her a pair of cables, one with 
120VAC and the other with a telephone connector and tell her to plug her fax 
system in.   I will feel successful if I can eliminate all need for 
commercial power, the internet, and all telephone systems.  Full duplex is 
just another example of Gerald's incredible insight!

I will say that before we finally got it all straight, I couldn't hear it.
Luckily I have a friend who does a lot of audio work and he was the only one
that could hear it out of my usual group. I sent him some audio recordings
that I recorded into a dummy load and he ran his analysis software which
showed flat tops on some of the peaks and some spikes. When I had it set
with enough audio drive to provide 100 watts out it was even worse, and the
TX Meter set on MIC showed sporadic spikes that would peg the needle in the
red. No matter what I tried those needle spikes where there unless the audio
drive was so low I was lucky to get 20 or 30 watts out at 100% on the drive,
and the issue was still there just not as pronounced. The analysis software
showed the spikes and flat topping. I also tried a couple of different mic's
and that didn't change anything. 

After scratching my head for a while I remembered something Dudley had told
me about turning the Leveler off because it was handled by the rack gear.
Well if that's the case why not turn the software mic gain to zero and use
the mic gain on the preamp. I did some more recordings and low and behold
the artifacts were gone. I set the mic gain on the external preamp to where
the TX Meter set on MIC hovers between -2 and 0. The needle is now stable
without any of those nasty spikes and my friend can no longer hear the
tearing, he ran another analysis on some recordings, other than I was
driving it a touch hard, the spikes and flat topping were gone.

I don't think it's a software problem, you just can't use mic gain in two
places, which kind of makes sense. I have already had one person tell me
that's how they run their system and another has tried it and says it worked
for them.

Rob, W1AEX, who wrote an article on setting up your gain listened to me on
AM the other day and recorded it along with a video of his PSDR. Its posted
on Youtube at this link http://youtu.be/G-aDcy0z2ds . I dont have any
recordings of on air SSB, but everyone tells me it sounds Great.

I know Dudley said he was going to try and duplicate this in the lab, and I
hope his findings are the same. There are so many variables between systems
it may be a tough nut to crack. This has worked for me and at least one
other person who e-mailed me direct so I'll post my settings one more time
and would like to hear from anyone else using external rack gear.

Mic Gain 0
Mixer Bal Line In all the way to the top 
DSP Phone Buffers 4096
External Mic gain set to bring the TX Meter MIC needle between -2 and 0 

That's it, your results may differ ..

Thanks

Thanks Dudley. But this has been done many times over the years. I wish 
I wouldn't have said anything. Many were in denial in the beginning. 
Some people just don't have the high frequency hearing and they hear it 
to a lessor or non existent sense. Others are not in to Essb audio and 
probably don't know what to listen for. So you seeit really is a 
losing battle. We had a test here on the west coast many years ago where 
someone rotated transceivers between the 1000 , the 5000 and another 
transceiver. At the time, I and 4 others  picked out the 5000 almost 
every time. It really is no big deal anymore. I shouldn't have replied 
to the original email and opened this up again. I just don't want to go

[Flexradio] Audio Rack and the 5000

[mike]

The tearing of the audio has been noted since the first production of 
the 5000. Flex was aware of the problem from the beginning and said they 
would look into it. They worked on trying to fix this problem but they 
never found the  cure. This is something we just have to live.

[Flexradio] Audio Rack and the 5000

[Craig Gagner]

I previously posted that I had all of my Audio issues under control, but, I
still had a small tear on audio peaks that was pointed out by a friend. I
watched my TX Mic setting meter and I just couldn't get it to settle in
between -2 and 0, I would get occasional spikes and that's where the
clipping showed up. I was told it sounded like crunching potatoe chips on
the peaks.

 

I do all of my audio processing external from the software, via a small
audio rack. I am using a PR-40 mic and it needed a preamp to drive it into
the EQ. Now since I am using an external preamp I set the mic gain slider on
the main software page to 0, I then went to the Audio Mixer menu and pushed
the Bal Line In all the way to the top. I set my TX Meter to Mic and
proceeded to adjust my external mic gain on the preamp until the meter read
between -2 and 0 on peaks. Low and behold the meter was very stable and no
more sporatic spikes. The ALC also hovers right between -2 and 0 as well .
Audio reports stated that the clipping and crunchies were gone, it sounded
clean and was the best it has ever sounded. I cant guarantee this will work
for everyone, but it cleaned up my audio 100%. If you use External
processing gear I highly recommend giving this a try.
