[Flexradio] PowerSDR recordings not faithful to the original
Greetings gents, Using the quick record button on the PowerSDR console I've noticed that the low bass response is lacking when compared to the original. That is, the bass in not as deep and full as the original. I've checked my transmit bandwidth and made sure it was as wide as the receive filter (from 0 to 3100) but I was wondering if there were any other parameter that would affect the recording frequency response. I'm using Power SDR 1.18.3 and 1.18.5 with the SDR-1000 Edirol FA66 at 192K. The sampling rate is currently 48000 but the other rates didn't seem to change the response either. My recordings were compared with a Flex 5000A which reproduced the signals faithfully. Could this be a limitation of the SDR-1000?

[Flexradio] DDUtil and Palstar AT-Auto Tuner Interface
I have just ordered a Palstar AT-Auto tuner and was wondering if anyone here has this setup at their station? I have DDUtil installed and working fine and while I'm waiting on my tuner to be delivered, I was wondering what cables I'll need to interface the tuner, computer, and Flex 5000. Also, where will the cables go, between the tuner and computer or tuner and rig? Any help will be appreciated.

Re: [Flexradio] DDUtil and Palstar AT-Auto Tuner Interface
Jim, I use the Palstar AT-Auto daily in an automated fashion. You'll need a physical serial port on your computer. Connect that via a serial cable to the Palstar. Config the Palstar for Kenwood CAT at the correct baud rate. Use DDUtil and the Passive follower box to set it to the physical serial port on your computer where the Palstar is connected. It will automatically send the correct frequency to the Palstar. These are the basics but should get you started. It works flawlessly. It does take some time for the Palstar to roll the inductor between 160M and higher bands so you must be patient before transmitting. However, it's an awesome tuner and worth the wait. 73, Mack de WB4MAK http://www.nfarl.org http://www.sedxc.org -Original Message- From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of James E Watts Sent: Monday, February 22, 2010 10:00 To: flexradio@flex-radio.biz Subject: [Flexradio] DDUtil and Palstar AT-Auto Tuner Interface I have just ordered a Palstar AT-Auto tuner and was wondering if anyone here has this setup at their station?

[Flexradio] What a blast!
Hi All! Since the majority of messages on the list seem to be problem related I thought I'd make a posting about how much fun I had this weekend with my new F3K ;) I decided to have a go at the ARRL International CW DX contest over the weekend just gone, it's the first time I've ever had a go at this particular contest. Currently I only have a delta loop for the 40m band erected in the garden so there was no choice when it came to band selection, 40m or 40m, that's was it! On the run up to the start of the contest I grabbed a few rare DX stations in the Caribbean area who were just warming up which was great as I bagged a couple of islands that I hadn't worked before. Then the contest started, I tuned down to the bottom of the 40m band and started trawling upwards working US stations one at a time as I went. I was amazed how many stations there were in such a small amount of space, I had the F3K filter set to 50Hz and used the panafall display. It was so easy to find each station using the waterfall display and the panadapter (Panafall) to ensure I was smack on frequency, then getting the DX US station normally on the first call using just 100w from the F3K into the full wave delta loop antenna. With the filtering set at 50Hz I was able to work the US stations even if they were almost on top of each other and grabbing the weaker stations even if they were next door to a large contesting station was a doddle. I was able to find and work far more stations per hour than I ever could with my conventional radio, mainly due to the narrower filtering and the fact that PSDR takes the guess work out of finding each station. Early in the morning when all the neighbours were asleep and TVs were turned off I fired up my trusty Ranger 811H amplifier, this would be the first time I had used the amp and F3K in anger and I am happy to report they worked faultlessly throughout, a perfect combination! Since I was working more stations per hour than ever before I found I needed more breaks, the old gray cells aren't as lively as they used to be, but it was a most enjoyable experience. Whilst trawling for stations I used my Schurr Profi II twin paddle for each contact, key in left hand, mouse in right hand, it's handy being ambidextrous! Later on I settled on a frequency and called using the PSDR CWX facility, whilst not as much fun as using my lovely twin paddle I was surprised how easy it was to contest using this mode of operation, I've never used the keyboard for CW before, I'm a bit old school, but once I had the pre-prepared messages saved in the onscreen memory slot I was able to work stations just as quick as when using my twin paddle, but without the wrist fatigue! I thoroughly enjoyed contesting with the F3K and am really pleased that I went ahead and bought it even though I had some doubt initially, it really is a super CW rig! Mike.

[Flexradio] QSK -- It's not...
Hi, Mike... Read your blog. As a long-time CW operator (licensed ~1946), and having owned both TenTec and Elecraft rigs with perfect QSK, I was really deeply disappointed in that aspect of the F3K -- it is a typical semi-break-in rig. I had a fair amount of trouble using it with my paddles, so shifted over to the keyboard. It is a more or less reasonable CW semi-break-in rig when used that way, but it is still obvious that the designers were SSB or AM types that did not use CW in their ham activity. I hope your comment about pSDR 2.x is right, but I don't hold out much hope, reading the reflector and all the jazz about audio quality, etc. The only saving grace for CW is the digital filter system...as you say, it is absolutely superlative. For a long time I was reticent about making noise over the lack of CW capability. I finally did so, more in the way of criticizing the ads' wording about break-in than anything else. I see that the latest web page ads only specify semi-break-in. I think it is important to comment or even complain bitterly about the lacks of the F3K in this regard. Amusingly, I did see a comment by an owner of an F5K, who used the dual receiver to provide a kind of break-in. Unfortunately, we poor cousins don't have that option. Another comment on the reflector was from an op who claimed that full QSK was just an annoyance! Go figure. I personally couldn't give a hang about audio quality. I'm not in the broadcast business...just give me a carbon mike salvaged from a WW-2 fighter! But since we come to praise Caesar not bury him, I thought your blog struck a nice balance. We wait impatiently for Ver. 2.x (along with our F1.5K)! 73 John Ragle -- W1ZI ___ 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://kc.flex-radio.com/ Homepage: http://www.flex-radio.com/
Re: [Flexradio] QSK -- It's not...
You would be wrong about some of the things you say. When I operate outside of my car. CW. I have top tens in DX contests, my cw speed is 40 wpm with good copy, 50 wpm in contest mode and I have been a developer of software for the Flex radios since the 3rd month of their existence. When I still cared, I was on the honor roll in only one mode, CW. I cannot stop the hype writers from doing their job and I did not get to review early copy of ads, but PowerSDR 1.X has always been a decent semi-breakin radio at best. The web pages and ads no longer MENTION QSK so far a quick look just showed me. The early ads did in fact mention QSK without understanding that this had a huge number of implicit declarations, just as you have mentioned. PowerSDR 2.0 switches from TX-RX for receive in more than adequate time for QSK. Keydown to RF out is under 20ms. There are issues dealing with agc memory across transitions which we have put down the list for PowerSDR 2.0 in order to do other work which Flex feels is higher priority for the release of PowerSDR 2.0, such as full support for Flex 1500, Flex V/U, diversity/phased array reception with the Flex 5000 and some other things which are less important. PowerSDR 2.0 and its plusses and minuses and current efforts are discussed in FlexEdge reflector, not here. But let me say this much. HUGE strides have been made in moving the software towards full QSK operation. So I will only say stuff here to dispel the incorrect interpretation you make about what it is we are doing or what we care about. From our tests, we believe the hardware will switch back and forth in well under 10ms and we are spending serious time in figuring out how to cut transition time and transitory response. We have reduced all of that to 1/3 of what it was before in PowerSDR 1.X. The switch times are as good or BETTER than Elecraft K3, Orion 2, ICOM 7800. We have two software ONLY issues remaining to make it QSK and that is going to take some sofware engineering that we do not want to do so the hardware mentioned is fully supported before Dayton. Best wishes and it really is like Gerald is fond of saying, you are going to be able to download software soon, and have a new radio. 73's Bob N4HY On 2/22/2010 1:31 PM, John Ragle wrote: Hi, Mike...

Re: [Flexradio] Acronis Online Backup
A proper backup isn't done until you have 3 copies. :) Any of the online ones are fine. Your choices are Mosy, Jungle Disk, Bitdefender and about 100 others. Or, you can weekly back up to your big external hard drive and keep it in your trunk. That solves the lightning issue (I should do that).

Re: [Flexradio] 3000 poor audio
You probably need to get a bus connected Firewire card and us it rather than the motherboard integrated Firewire controller. The problem with motherboard integrated devices is that the engineers who designed the board, integrated the Firewire port as a marketing feature and probably didn't engineer it to operate at peak performance. I suspect if you look at the IRQ allocations, it will be sharing IRQs with other devices like USB controllers and such. The FLEX-x000 series of SDRs do not use sound cards, so the only way the one in your PC could be causing problems is if it is sharing an IRQ with the Firewire controller. This KB article lists some Firewire controllers that have been know to work well. I also believe that Neal (K3NC) http://kc.flex-radio.com/KnowledgebaseArticle50179.aspx Also, what version of the Firewire driver are you using? -Tim -Original Message- From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of Michael Walker Sent: Monday, February 22, 2010 10:31 PM To: FlexRadio Reflector Subject: [Flexradio] 3000 poor audio I've just installed my 3000 on my Quad core i5-650 with 8G or ram (wow, this thing rocks), and after about 30 seconds, the audio starts to 'rip'.
