[Flexradio] Wonder Radio
ZS6AVM Wrote: I spoke to a friend in VK (VK7ZE) on 20M yesterday, he mentioned that he'd spoken to a Ham in the States who was using the Wonder Radio (1Watt version driving a 100W PA) The conditions were poor so I couldn't get the call of the State Side Station he had mentioned I was wondering if the Ham in question reads this Reflector, if so, perhaps he could provide us with some feedback with regards his impressions of the Wonder Radio Regards Dave J (the only Flexer in Southern Africa, or perhaps even in Africa ??) *** Disclaimer: Denel (Pty) Ltd t/a Denel Aviation (Denel Aviation) Registration number: 1992/001337/07 This message and any attachments are confidential and intended solely for the addressee.

[Flexradio] Transmitting on MARS frequencies
GM, How do I get Power SDR to transmit on MARS frequencies, 4032 KHZ USB, for example?

Re: [Flexradio] Transmitting on MARS frequencies
Chas, It is not only PowerSDR, but also firmware in the Flex-5000 that limits transmit frequencies. It can be done, but you will need to contact FlexRadio support to resolve this. 73, Ray, K9DUR ___ 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] Future VHF/UHF transverter and RFIO versions
Hello Flexers, I had a couple of customers who wanted to know if the planned future VHF/UHF internal transverter requires the new HFRIO ASSY 34 board. The answer is NO unless you want to operate full duplex on satellites. The ASSY 27 board will work fine for normal half duplex operation.

Re: [Flexradio] RX1 in/out issue with FLEX5000
I too have a similar issue as Mike. Mine is a 1070khz 25Kw station 3 miles away, images of it showing up all over the dial on my brand new 5000A using PwrSDR 1.12 (the version it shipped with). Therefore I too am looking for a RX1/2/loop solution. If there¹s any others with the similar issues, who¹ve found a solution, it would be appreciated if you shared it. I don¹t get this issue with my FT-9000, IC746 or JST-245 on the same antenna. Only my Flex 5000A w/ATU has thee AM BC signal images up down the dial... Its my only complaint about the radio¹s RX. Thanks!

I have IMD/spurs/carriers all the way up from 160M to past 20M. The signal strength of the AM 640kc station is -3dbm on the flex meter and I have crud all over hell's half acre up thru the bands...most are just above the QRN, but sometimes not ;-)This AM powerhouse always mixes with another station beating together on frequencies that show up across the bands. I purchased a KIWA BCB reject filter and put it in the RX1/2 in/out loop and use the antenna selection option to put this inline and it definitely knocks down the 640kc AM 70db when the flex is in GEN mode tuned to 640kc. The problem is that when the BCB filter is inline with RX1 loop, I have major intermod all over the bands...on 20M I heard CHU this afternoon at 14.030, +/- propagation and AM carriers all over the spectrum, some are S9+10 in DSB mode on 20M. If I take the KIWA BCB reject filter and put it inline with the antenna in any ANT1/2/3 port life is good...all the crud is gone, but I can't TX with the KIWA BCB filter. Anyone care to figure this one out? I know W9NQN TX/RX filters are an option, but a $60 RX only should have worked IMHO. Enjoy what's left of our holiday weekend!

Re: [Flexradio] TX Audio Quality Help, please!
Hi Frank, Thanks for the reply! I can probably post any sort of format, but you may have to help me out a bit - I don't know what flac-compression is. The original Flex WAV files (recorded at 96 ksps) are on the order of 10 MB each. To get them down to a reasonable size and to record two files side-by-side (because it makes comparisons much easier), I played both back (using the Playback feature of the Flex WAVE tab) through the Edirol FA66 on one of my SDR-1000's. I connected the FA66's analog output to the analog input of my Delta-44 on the computer I use with my other SDR-1000 (via a patch cable), and I recorded them using the free version of Audacity. The record sample rate was set to 44.1 KHz. I then used Audacity to edit out some of the silence time between the two recordings, and I converted the file to an MP3 using their recommended mp3 plug-in. Audacity can also export as a WAV file (although I've never tried this), and I can change its sample rate to 48K. Would something like this be acceptable? (And is flac-compression an option for WAV file generation?) Or I could post the original Flex WAV files - zipping them up will reduce their size somewhat, but they'll still be HUGE. The advantage, though, is that there won't be any distortion introduced by this process, and anyone can listen to them (as long as they have a Flex radio) in their full, 96 ksps glory. By the way - I should mention that the mp3 files that I posted sound surprisingly similar to the original files (to me at least - I can't tell any difference), but I'd be happy to try something else. Thanks again, and 73! - Jeff, k6jca P.S. I'll be away from the computer for awhile. Will hope to respond later this evening...

Re: [Flexradio] TX Audio Quality Help, please!
Hi Jeff, I've heard another flex 5000 user sound like that. It has almost a digital processed type sound. A group of Flexers in my area use W2IHY Boxes for better sound, especially with the PR40 although personally I don't feel that hardware should be required to make a software radio sound better.

Re: [Flexradio] TX Audio Quality Help, please!
Are you talking about the distortion that's inherent in the 5000 ? I've heard that it's a problem with the DAC in the soundcard. I don't believe the 5000 will be an audio aficionados radio in it's present state. The 1000 doesn't seem to have this problem (at least not with the firebox or fa66) I've seen guys with 1000's run computer mics and make them sound like a million bucks.

[Flexradio] 5000A Radio Hangs Up
I've run into an issue where PowerSDR hangs up when I open another window on my PC. For example, if I open Yahoo mail and read an e-mail, the radio goes silent and I have to stop PowerSDR and start it to operate. As soon as I do anything with a mail message again, it does the same thing. This did not happen with the the version prior to 1.12.0. Any suggestions?

Re: [Flexradio] 5000A Radio Hangs Up
Yep, don't check you mail, you should be playing radio :-) If your Firewire driver is not in Safe Mode 1, change it to SM1. I have this problem with MS Outlook. For some unknown reason, it is responsible for some hardware generating a lot of high latency DPCs. There were some things I did that helped some, they are: 1.) Updated the video driver. 2.) Updated the NIC driver (it may be in your chipset driver package if it is on the mother board) If you are using a laptop and/or Vista, the problems can be worse. PowerSDR v1.12.0 is more CPU intensive especially if you have an RX2 installed which is probably why you are seeing the problems now. BTW, my opening statement also has a bit of truth in it. I don't run Outlook anymore when running PowerSDR with an RX2 even though my CPU utilization is well below 20% on a multi-core Intel CPU running XP.

Re: [Flexradio] TX Audio Quality Help, please!
Jimmy, I've used both the Delta-44 and the FA-66 with the 1000. As for the 5K, I can only judge by the ones I've heard on the air and my own, and whether I use a PR-40 or an HC5 cartridge, it sounds very good, with no trace of audible distortion. I listened to Jeff's recording and I agree that the second half of the recording sounds quite bad. I'm only saying that I have not heard that on the air, and certainly haven't heard it from my 5K. For that reason, I wouldn't expect that the problem is due to any inherent shortcoming in the DAC, or all FLEX-5000's would sound that way, and they do not. Regarding the monitoring setup, I've used the Icom 746PRO set to it's 3.6K 'Sharp' bandwidth, while monitoring the audio from the rear panel (cleaner and wider bandwidth than the headphone jack) with several pairs of headphones, including (at various times) the following models: Beyerdynamic DT-880 Beyerdynamic DT-990 Grado Labs SR125 Grado Labs SR325 The monitored audio has been very clean with all of them, with no change in character regardless of whether I run 1 watt or 100 watts. I'd be happy to set up a sked sometime to run some comparative tests. 73, Dale WA8SRA Jimmy Jones wrote: It's certainly your right to disagree Dale but I've heard the same comments from two of the best ears that I know. If they say it's distorted you can bet the house on it that it is. I'm talking about guys that tell me when I'm a 1/2 cycle off frequency and nitpick like that. I hear this same distortion in the 5000 too and my ears are terrible. I don't see it as a show stopper but it isn't flex perfect like it should be. I've seen several guys struggle to get the 5000 sounding decent (and they did eventually) The SDR 1000 on the other hand is no struggle at all to get sounding good and it doesn't have that weird distortion like the 5000. The guys that I've talked to on the 5000 that sounded good were running very ,very expensive mics. The guys running Heil mics had typical communications sounding audio and you could no doubt hear the distortion. The 1000 doesn't really care. Most any mic sounds good on the 1000. You didn't say what sound card you were running with your 1000 Dale? On Mon, 2008-07-07 at 16:03 -0400, Dale Boresz wrote: I completely disagree. I have both radios, and the TX from both sounds superb using the Behringer UB-802 as a mic preamp only (no EQ) into the Line In on the 5K, and the Heil PR-40, with the EQ handled by PowerSDR.

The 1000 doesn't seem to have this problem (at least not with the firebox or fa66) I've seen guys with 1000's run computer mics and make them sound like a million bucks.

Re: [Flexradio] TX Audio Quality Help, please!
Jeff, a couple questions. What version of the code are you running? Have you tried different versions to see if it affects the sound? If you back off the mike gain does it still sound grainy? Are you feeding the 5000 output into a dummy load for your recording? Have you tried it on a different band to see if it's RF? The third recording sounds slightly better then the first two when you back away from the mic. My 1KSDR had this problem until I added an EQplus in front of it. Working with Julius (W2IHY), I knew this was RF but I couldn't get rid of it. Maybe I didn't have the correct ferrite beads or bypassing. But adding the EQplus fixed it for me. I also use a PR40 and my shack is directly under my W5GI antenna. As a side note, if you are ever looking for software to measure THD, I use the following from www.ymec.com. They have a 30 trial that you could measure THD with. Since this is amateur equipment and not commercial grade I have not done this with my radio gear but I might be a fun test.

Thanks to everyone for their replies and suggestions. To answer some of the questions I've received... 1. I've run IMD tests on both the 1K and the 5K and at various powers (3 dB steps). 2. The problem seems to be independent of code version. 3. All tests are made into a dummy load. 4. The PR-40 is connected directly to the Balanced Line In of the 5K. 5. I don't run the compandor or compressor. And I keep the mic signal below 0 dB. 6. I don't believe it's a problem with mic gain, or rf feedback into the mic, or something else in the input stages. I believe that my third recording (the July 6 recording) bears out this conclusion. If I listen to the signal at the TX Driver output, it sounds fine to me - if there was any sort of problem with the mic (gain or rf feedback, etc.) you'd hear it here, too, because we're well past the mic input circuits. But I don't hear any noticable distortion at this stage. It's only after the *next* stage in the TX chain, at the PA output, that I hear the distortion - that is, the second half of the third recording (this audible distortion correlates well with the differences between driver stage IMD and final stage IMD). Why do I have a problem and others (such as Dale) don't? Is there something wrong with the way I'm testing this? Is there something in my voice timbre that's not in other voices and that exacerbates this problem? Is it something else? I've no idea. Dale sent a screenshot of his eq settings.

Re: [Flexradio] TX Audio Quality Help, please!
Jeff, FWIW, I was never able to make the balanced input work with my PR-40. I always ended up with extra grunge in the audio. When I use the standard microphone input on the front panel it worked much better, but the arrangement that produces the best audio for me is to use the Line In jack on the rear panel in conjunction with a mic preamp. I like the idea of driving the radio with a larger amplitude low source impedance than with a higher impedance very small signal (like the direct output of the microphone).

Frank, I agree, I'm sure the distortion is not in the ADC/DAC components (nor software, nor input stages) either, because I don't hear it at the 5K PA's *driver stage* output, which is well after the output DAC (ref: 1st half of 6 July recording). The problem only pops up at the output of the *final* stage. And this is why (per Dale's comment) I don't think it's a problem with the balanced line input. If this input was causing the audio to sound grundgy, then I'd expect to hear it at the PA Driver stage, too (1st half of 6 July recording). But I don't. (But maybe I'm missing something really obvious, or doing something wrong. Suggestions?). Per Jim - this 5K (my second one) is right out of the box, and I didn't recal PA bias (I shouldn't have to, right?). By the way, I had this exact same problem with my first 5K, too, and I could not fix the problem despite numerous bias recalibrations as well as experiments with various bias settings, so I'm skeptical that recalibrating bias will have any appreciable effect. Still, it wouldn't hurt to give it a try. I'll try to get to this tomorrow.

You have to wonder about the leveler settings. 73 Frank AB2KT -- Sapristi nabolis! -- Count Jim Moriarty ___ 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] TX Audio Quality Help, please!
I agree, it's peculiar. But again - if it's a leveler issue (i.e. software) I'd expect to hear it at the PA driver, too. But I don't (but perhaps others do? Ref: 1st half of 6 July test). By the way, I just checked, and the Leveler has been OFF (box not checked) for all of my tests. The only TX effect I have enabled is TX EQ, which is set to the same EQ values for all of my tests. What I wonder is this: can distortion at RF (rather than at AF) have this same soft compression effect, after the RF is demodulated? - Jeff Frank Brickle wrote: On Mon, Jul 7, 2008 at 7:30 PM, Jeff Anderson [EMAIL PROTECTED] mailto:[EMAIL PROTECTED] wrote: Frank, I agree, I'm sure the distortion is not in the ADC/DAC components (nor software, nor input stages) either, because I don't hear it at the 5K PA's *driver stage* output, which is well after the output DAC (ref: 1st half of 6 July recording).
