Edwin MarzanAB2VW According to hams on both sides of the issue, bandwidth is both the problem and the cure, but you can't argue with the modern science of sound, based on almost 80 years of solid research since those outdated telephone studies were created: By extending telephone bandwidth to 7 kHz and beyond, it is clear that one can markedly reduce fatigue, improve concentration, and increase intelligibility. It is also clear that this improvement is even more significant in real-world room situations, where the sound is often degraded by reverberation, projector or air conditioner noise, accented speech, and other acoustic problems that are encountered in business telephony. Additionally, extending telephone bandwidth below 300 Hz brings a significant increase in presence and realism. In his 1938 paper discussing the bandwidth of the telephone system, ATT's Inglis noted that, 'Frequency limitation is essentially an economic one, subject to change as conditions change.' Here in the twenty-first century, economics and conditions have changed as Inglis predicted, and modern telephony is now in a position to deliver on the promises of wider bandwidth and clearer speech. http://www.polycom.com/common/documents/whitepapers/effect_of_bandwidth_on_s peech_intelligibility_1.pdf That said, everyone knows wider bandwidths should not be employed on very crowded amateur bands, nonetheless, the key to intelligibility and fidelity is b a n d w i d t h. About 8 KHz is super and 6 KHz is very good. When transmitting through a 3 KHz filter, some kind of EQ is necessary to relieve muddiness, unless the microphone element attenuates the low end dramatically, beginning at about 150 Hz and as long as it has a corresponding rise of about 6 dB at about 2 KHz. Bob Heil knows this and his mic's are designed accordingly. The EQ built into the PowerSDR software does a great job. If the next hardware edition of Flex-SDR has a preamp and 48v phantom power, I'm there. _ Instantly invite friends from Facebook and other social networks to join you on Windows LiveT Messenger. https://www.invite2messenger.net/im/?source=TXT_EML_WLH_InviteFriends ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base:
Re: [Flexradio] FW: The inherent muddiness oftypical amateurtransceiver audio without EQ
You have no idea how much it would please me to be able to communicate full duplex on 75 meters. And I am not at all sure that won't be possible given the characteristics of some of the new modes! I make no claims to be able to see all of the future possibilities but you can be sure that I have no intention of returning my Flex radio! And I want to thank all of you who participated in my poorly done informal effort to find out how those fine people who share my interests think. By doing so I hope to improve the effectiveness of my mentoring and elmering which, to date, has been somewhat disappointing. Of the seven I have attempted to help in the last two years only two have, as we might say, borne fruit. I want to improve on that as well as obtain better returns on my rather substantial financial inventment! The XYL says I have to learn more. 73 Lee K9WRU - Original Message - From: Jerry Flanders [EMAIL PROTECTED] To: Lee Mushel [EMAIL PROTECTED] Cc: FlexRadio FlexRadio@flex-radio.biz Sent: Tuesday, June 03, 2008 5:20 PM Subject: Re: [Flexradio] FW: The inherent muddiness oftypical amateurtransceiver audio without EQ At 06:02 PM 6/3/2008, Lee Mushel wrote: snip What on earth is the point of worrying about whether or not there is space between dits at 60 wpm?

I used the full QSK of my new K3 in a CW contest 8 - 10 days ago and I tell you I REALLY enjoyed it and used it to my advantage.

Re: [Flexradio] Second receiver diversity reception...
Hi Steve, Over time, we will make a number of RX2 features available through software enhancements. To do diversity reception with the initial release, you can hook RX1 to one antenna and RX2 to another. You can then tune both receivers to the same frequency adjust pan/level to provide the best signal to noise ratio. Future software will add more inteligence to this process as well as the ability to notch or enhance signals.

I have the 2nd receiver ordered and it is coming in the first production run. What about diversity reception? The Flex home page mentions diversity reception will be possible. I assume that means the hardware will support it, but PowerSDR must be enhanced to support it. What are the plans for diversity reception? How soon? That is the main reason for my order. I use the MFJ-1026 noise cancellor to cancel out local noise source. A local birdie literally wipes out reception on 7076 kHz, the 40 meter JT65A frequency. And yes I have successfully run JT65A with WSJT on my 5000A. My MFJ-1026 is routed through the RX1 loop, so the T/R switch is not required. Thank you Flex! My hope is that PowerSDR the 2nd receiver will replace the MFJ-1026. The phasing and amplitude could be done digitally, with the settings saved for future use. Perhaps there are programmers in the Flex customer base that can write the code for diversity reception. Certainly it is beyond my skills. 73, Steve N6VL ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kb.flex-radio.com/ Homepage: http://www.flex-radio.com/ ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kb.flex-radio.com/ Homepage: http://www.flex-radio.com/

Re: [Flexradio] FW: It's all about articulation, Phil (inherent muddiness, of course)
Here is one thing to keep in mind. The frequency response of the mic inputs are FLAT on the FLEX-5000. Just about every other ham radio transceiver has pre-emphasis engineered into the mic preamp circuit which is probably why the TS-870 sounds a little better than the F5K without any EQing. -Tim -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Edwin Marzan Sent: Wednesday, June 04, 2008 2:34 PM To: Phil LaMarche; flexradio@flex-radio.biz Subject: [Flexradio] FW: It's all about articulation, Phil (inherent muddiness, of course) Er, ehm, so which is it?

Aparently there is a disagreement as to the cause of the muddiness although the limited bandwidth explanation makes sense to me. So is the cause lack of articulation or lack of bandwidth?
