Re: [Flexradio] intermittant power glitch
I had similar [but not identical] situation happen after I installed the RFE board. My three board stack [two and one half years old and NOT in an enclosure] had been running fine for the past six months. After installing the RFE board, I would occasionally see issues similar to what has been described, with no pattern. I always had to cycle power to get things back to normal, but one day I went to check the connectors on the hardware and it came back to life. After taking the complete stack apart and cleaning all the connectors between boards and re-assembling, I have not had any of these weird experiences. I am convinced it was an intermittent inter board connection problem. Joe K1RQG In a message dated 2/9/2006 9:04:38 A.M.

The reworked ALC is awesome and totally transparant. It's the first time in the history of rice boxes that an alc has actually worked without massive distortion! Also, the peak power distortion on the 1 watt predriver is cleaned up. The peak power meter shows around 125 for ssb and 200 for am which is EXACTLY the way we need it to work.

I confess I'm not all that up on how to automate testing with a graphical interface, but there are tools out there that do this intelligently (i.e. it's not just a memorized sequence of mouse clicks and keystrokes that depends on screen locations). The good tools (i.e ones that are clever, and don't require months of setting up configurations and scripts) might not be cheap, though. However, I can envision something that could transmit a test signal from one SDR, and measure it with the other one. Stuff like image rejection, filtering, AGC dynamics, etc., would all be pretty straight forward. You could change the Tx EQ while transmitting a .wav audio test file with pink noise and look at the spectrum from the receiver, or just at total power. Jim, W6RMK Eric Wachsmann FlexRadio Systems
Re: [Flexradio] NEW ALC AWESOME
Shouldn't peak power for AM be exactly the same as SSB?In other words, if I cannot transmit more than 125 watts, peak, with SSB (to prevent amplifier distortion), then I'd think that I shouldn't be able to transmit more than 125 watts, peak, with AM (andthe AM carrier power should be 1/4 of that, or around 31 watts).What am I missing?- Jeff, WA6AHLBill Nagle [EMAIL PROTECTED] wrote: The peak power meter shows around 125 for ssb and 200 for am which is EXACTLY the way we need it to work.
[Flexradio] Peak Power AM vs SSB
There is a phenomena in linear amps that are used to transmit AM: The AM carrier causes a flywheel effect which fills in the missing parts of the rf cycle. This allows operation at higher peak powers without i-m distortion being generated. This does NOT happen in ssb modes. Thus you can run more peak power on any given amp on AM. I can run my SDR at the 25 watt carrier out level and modulate around 200% in the positive direction (the negative peaks dont cut the carrier off due to the operation of the balanced modulator) without any i-m generated.

Re: [Flexradio] Fwd: PowerSDR Beta Preview 13 has been Released.
Gerald and Paul, I don't have the DUBUS article around. How exactly is the compression done in SDR-1000? According to my understanding the compression will increase the INBAND intermodulation distortion, unless the audio spectrum is sliced to narrow subbands that are individually compressed and then combined. Naturally, after the processing the final brick wall filter is compulsory. By the way, I miss the multichannel TX equalizer! 73, Ahti OH2RZ - Original Message - From: Gerald Youngblood [EMAIL PROTECTED] To: 'Paul Wade W1GHZ' [EMAIL PROTECTED]; FlexRadio@flex-radio.biz Sent: Thursday, February 09, 2006 4:40 PM Subject: Re: [Flexradio] Fwd: PowerSDR Beta Preview 13 has been Released.

Re: [Flexradio] NEW ALC AWESOME
Bill, Glad to hear that the new ALC is to your liking. The peak power meter is still not right as far as I can tell. AM peak should not be 200W, unless I am missing something. The Leveler is used basically to apply a very slow AGC to the microphone in order to keep the volume from dropping dramatically when you turn your head or move the microphone. It is kind of the inverse of the ALC at a much slower pace. It tries to keep the peaks in the right range by raising the gain when it is too low.

Re: [Flexradio] Interface changes (was Version 1.4.5 preview 13 Bug)
The simplest would be to make the right click a 3 way toggle 1 VFO A 2 VFO B with a different color cross hair presumably the same color as VFO B's Freq color 3 Off If I was going to add a button I would make the button turn the cross hair on and off and let the right click toggle A and B That was exactly what I was advocating (hence the red crosshairs suggestion for B). The off position is sometimes useful because it's a big bit of real estate and I've occassionally clicked it in error. Not really a good thing when it happens. Larry WO0Z
Re: [Flexradio] PowerSDR Beta Preview 13 has been Released.
I read the release notes and, yes, I experience exactly what was described: // Note that because the ALC was non-functional // in the last series of releases (since 1.4.5 started), // the output power for inputs which are being overdriven // will be attenuated. As a reminder, on SSB, you will // not get 100W on a bird wattmeter. Something closer to // 30 or 40W is a more reasonable expectation for average // power for most voices/microphones. Now, would someone please explain to me why I still see 100+ watts on the peak power meter of the SDR while the external wattmeter peak power reads about half that? Also, please tell me why I should be happy with half the power I used to put out. I assume the answer will be something like you were overdriving and distorted before, now you are not. The signal reports I got were nothing like that, I might add. Sorry to pose questions which may be obvious to most, but I really would like to know.

[Flexradio] test files
You've got sample WAV files for things like SSB and AM signals off the air, but it would be quite handy if you would post some sample WAV files with things like single tones or two tones, and tell us what they are (i.e. where is the center frequency: 11.025 or what). That way, we can experiment with alternate signal processing, or with generating other test files, and have something to compare against. (i.e. if you have a file with a 1kHz tone, and I generate a file that I think should have a 1kHz tone, I can compare mine against yours to see if my program works) Just as a cross check, the first SSB file appears to be 2 channels, 32 bits/channel, 382976 samples at 48kHz (just under 8 seconds of data).

Re: [Flexradio] PowerSDR Beta Preview 13 has been Released.
Gary, After I got this message, I went back and took my measurements again using a scope. I am seeing peak power up to ~140W with the AVG power around 45W depending on voice characteristics. This is what we were targeting with the new ALC. Why should you be happy with this? Because it is an extremely linear ALC that allows you to over drive the heck out of the input without having to worry about damaging your transmitter, and without splattering all over the band.

[Flexradio] PowerSDR Beta v1.4.5 Preview 14 has been Released
PowerSDR Beta v1.4.5 Preview 14 has been Released. This release has quite a few bug fixes including the TXEQ which was broken in the last release. It also introduces W5SXD's CWX form for more CW sending options. Please read the release notes for more information. PowerSDR Installer PowerSDR Source Release Notes Eric Wachsmann FlexRadio Systems
Re: [Flexradio] PowerSDR Beta Preview 13 has been Released.
Hi, There's an item that I noticed in preview 12 and also in preview 13. When in Setup under the Transmit tab, you have the ability to define your own profile and save it. But when you restart Power Console, the saved profile is not there any more. 73, Chas W1CG
Re: [Flexradio] test files
I would like a description of each receiver sample IF file that is already posted on the site. It is not clear to me where to set the receiver when playing them.---You've got sample WAV files for things like SSB and AM signals off the air, but it would be quite handy if you would post some sample WAV files with things like single tones or two tones, and tell us what they are (i.e. where is the center frequency: 11.025 or what).
[Flexradio] Significant CPU Utilization increase with Preview 14
The CPU utilization on my system went from 3% with Preview 13 to 30% with Preview 14. All I did was import the database from 13 to 14 and started listening to 41 meter shortwave. I did re-run fftw_wisdom.exe for Preview 14 as I do with all versions and it made no difference in CPU utilization. -Tim --- Tim Ellison mailto:[EMAIL PROTECTED] Integrated Technical Services http://www.itsco.com/ Apex, NC USA 919.674.0044 Ext. 25 / 919.674.0045 (FAX) 919.215.6375 - cell PGP public key available at all public KeyServers Skype: kg4rzy
[Flexradio] CPU Utilizaton with Pre 14
Just installed Pre-14 and have found my CPU utilization has increased more than double than with Pre-13. No other changes in software or background programs. 73, Norman __ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
Re: [Flexradio] Significant CPU Utilization increase with Preview 14
Tim and Norman, I've tested previews 7, 9, 11, 12, and 14 on 40 m cw using a 3 GHz Pentium, delta44 audio, 256 sample audio buffer and 1024 sample dsp buffers. My cpu utilisation on versions after 7 is running between 4. 7 and 10.9 %. Version 7 is a bit higher at 7-12%. I see no increase with 14 over previous versions here. Anyone else comment?

Re: [Flexradio] PowerSDR Beta Preview 13 has been Released.
Ignore the peak power meter. It is a fiction and should be removed from the console. In order to answer these continuous complaints, we have placed arbitrary limits (clipping) on the values the meter would otherwise display. It is a fiction and I no longer support its existence. The peak power meter is a complete failure. It cannot be made to work at all because there is no feedback mechanism from the amplifier to this meter. It is not a sensor on the state of the amplifier, it is a sensor on what is the peak value in the dsp buffer. We would be better off with a dBFS meter. Nothing more clearly demonstrates what was wrong with the early incarnation of the AGC/ALC than this peak power meter issue. A single sample, would crush the entire buffer down. You are seeing the same phenomenon in this meter. Here a single large sample will say 200 watts when the average power in the buffer is 40w and in fact the amplifier has gone into compression.It was a mistake for me to ever add it and I apologize for the constant consternation it has caused. The forward power meter is only meaningful in the case of the amplifier where there is an A/D and a bridge. Again, its accuracy is only as good as the calibration and the impedances it sees. With the amplifier it is a computation of the average power in the buffer and is not a sensor measurement on the external 1 watt amplifier state.

Same here. I am still at 3-4% with my P4 3.2 GHz, D44, 512 audio, 1024 DSP. It didn't change.
