Quality Microphone Audio

Excellent! Now with the savings you can afford that new amp, antenna, or transverter you have always wanted!  Have fun!

I don't operate CW 100% of the time.  I shift to SSB if that's where the DX station is.  I chose Heil HC-6 in my mike profile and used what were the default settings for that.  And I will admit that I have received several unsolisited compliments on my audio.  This surprised me as it had never happened with my old FT-1000MP MkV Field. I made no changes other then to choose Heil HC-6 for my mic profile, and DX.  I think my preference for CW came from living with mediocre antennas and no amp for a long time.  CW gave me an edge.  326 confirmed on CW and only 244 on ssb.

I agree ... I never solicit audio reports but get many many comments how great my 6400 sounds and they always ask what microphone do I use and  how much did I spend for it.   I use the hand mic that came with it and hold it properly + set the smartsdr equalizer appropriately.

Not to mention your broadcast quality voice, Ernest!

N8SDR xmit bandwidth is 50-3500hz, yet 8Khz slider @+7db.  That's 4500hz above the hi cut. Is the 8K slider even doing anything ?

from what others have noticed yes there seems to be  much over lap in the EQ filtering. I  would like to see the Q and bandwidth that the EQ is based on

Terry AB2UE

My point is, any EQ frequency above the 'hi cut' should be cutoff by the hi cut given the slope of the filter in the flex radio.  I have used a audio signal generator[15mV] into my yaesu mic input & found that audio frequencies  above  the xmit bandwidth 'hi cut' are not present & do not generate RF output. I have plotted the xmit filter curve which is similar to a 'bell' curve, which is much wider than that of a flex. Perhaps someone could inject audio signals into a flex mic input to plot its filter slope.
My rule of thumb is to set the EQ frequencies within the range of the xmit bandwidth if possible. My yaesu parametric eq allows me to do that , where the flex graphic EQ  slider frequencies are fixed. Maybe a flex in my future someday. 73

The overlap means that there is some interaction between the 4K and 8K sliders as to how they affect the audio contour below the filter cutoff. When using a 3.5 KHz cutoff I don’t think that overlap will have much effect. In cases where the cutoff is between the frequency range of two sliders, there would probably be more effect of the overlap. I prefer in other cases to drop sliders to the bottom on ranges that will not affect the audio contour . This seems to keep those frequencies from overloading the processing stages. It is especially important with the bass sliders. But I have observed some smaller problems with extremely highly boosted highs as well. Steve Or Tim once posted a graphic that showed the frequency response curves of the EQ sliders. Of course, the higher you turn them, the more interaction they have because of the Bandwidth varies with the gain of the slider.

Ken, this is one problem with the PR781. You have to EQ to extremes to settle them down as they have such a heavy base response and suffer high freq.

In the case of N8SDR above I don't think the 4K and the 8K slider has much effect with his cut off settings, otherwise setting upwards of +7 on the sliders would be driving the PROC a little hard.

I remember that post from Tim, there has been some changes to the EQ since that graph, I wonder what it would look like today?

All I can say is the settings I posted work well for me, end of story.

Anyone try Neewer NW-600 Microphone with 48V P power supply -Best audio reports with this on many ham radios

Craig Williams

Agree!

I have used electrets (need bias), condensers (need 48 volt phantom power) and dynamics (pr781, pr40, etc). They can all sound great but I am partial to the dynamics. They don’t pick up much background noise, need no bias, are low output so need boost. I notice every talk show uses dynamics.

KL4QG

The main microphone going be RadioSport Headset with wide range condenser mic element -I do have icom SR 30 I like try need find someone make me mic cables etc for Flex 6400M
We all wait till after Alaskan nets are over than we help each other being helping someone with signal reports with new Dipole or Microphone fine tuning -We all have meet in person so we find that great why adjust audio -took me about 3 adjustments good go/

"Why do so many of us overkill our station?"

Perhaps because we like blinky lights and lots of control knobs almost
as much as talking on the air?   Or because we can, or because he who has
the most toys, enjoys their man-cave more?

Oh, wait, are we supposed to get on the air, or just stand back and look
at all the blinky lights?

David Decoons, wo2x

It is not overkill if you use the features.

I have invested in making my station fully remote, even though over 90% of my operating is done from within the front of the radio. But am glad I did. 

I have been in the hospital 6 times since August. (46 days total). Currently here Now and about to get on 75 meters from my iPad running SmartSDR for IOS and Node Red client. 

Node Red allowed me to program a Raspberry Pi to integrate amp control and monitoring, rotor control, and station power control into a browser window which runs split screen with SSDR for IOS.

besides I do it for the challenge. This week tentatively my early disability retirement kicks in and I need things to keep me occupied.
