[Flexradio] SDR 1.8.1 and WSJT not playing nice
Excellent knowledge center article on how to config: http://kc.flex-radio.com/KnowledgebaseArticle50362.aspx?Keywords=wsjt The problem is that WSJT 7 on my Vista machine crashes. The audio driver panel shows all 10 channels, and attempts to open 0 and 3, but then crashes with an error -9998 too many channels. I can't ever get to the setup option to change the audio channel selection. Anyone else seen this behavior?

[Flexradio] F3K and 6 meters
I am a relative newcomer to 6 meters, just getting my feet wet. I was using my TS480 for 6, until.oh.three days ago when my F3K arrived. TS480 just collecting dust now! But I have spent most of the daylight hours over the last three days on 6 meters, with my 2 element hex beam at 40 feet. I can only compare my Flex to the TS480 (which did really good for me this summer on Es so far). Well, the F3K seems pretty amazing. I heard two European stations this afternoon on CW on 6. NEVER heard that before. Very weak, but they were there. I did not try and call them, the pileups were notable. But the receiver on the F3K certainly, to me at least, seems to be performing quite well on 6 meters. I have read the other threads on this, and its nice to get a rig where I don't have to add another pre-amp to get it working as I want it. Thanks, Flex Radio team, for another great feature!

[Flexradio] 6 meters recieve on 5000
I guess I just dont understand why the 5000 needs to have a preamp on 6 meters. I will admit I like my 5000 better than my IC-7800 in every catagory except the recieve on 6 meters. The Flex, if we were scoring on a scale of 0 to 10, is about a 3 at best on 6 meter recieve compared to my 7800. Why cant there be a additional module or mod for the 5000 so it is up to par out of the box. No add on preamps. Just does not make sense to pay that much for a rig and it needs a recieve preamp on 6. Dont get me wrong, I love the Flex and would recommend it over any rig. I just think they missed the mark on this issue.

[Flexradio] flex 5000 laptop operation with windows 7
In the spirit of experimentation I attempted to run my 5000a with my Lenovo X61 laptop running windows 7 rc1 with a trendnet tfw-h2pc 2 port PCMI firewire card. The card was detected and pronounced operational by the operating system. I installed the firewire driver downloading the driver from the flex web site dated 4/29/09 it installed properly I then downloaded and installed power SDR. It prompted me that .net needed to be installed and so I did that. I then restarted the computer completed the install of powersdr 1.18.1 and launched it. Powersdr brought up the dos window where it does the fft checks. It then brought up a window where a progress bar indicated percentage of completion. At about 60% complete an error message came up saying it could not communicate with the radio and to please try again. Even though I power cycled the radio and restarted powersdr in various combinations, I still get this communications error. What's the best way forward to get this to work?

Re: [Flexradio] 6 meters recieve on 5000
What's the big deal ... Solution 1: Don't worry about, it's not all that bad, and when the band is open, its open ... you may miss a few weak ones. Solution 2: Add an external 6m Power Amp that also has a preamp. Solution 3: Add any one of the nice external preamps to the convenient RX IN/OUT Loop that Flex conveniently engineered in to provide a flexible and easy way to improve to anyone's personal taste. I only operate 6m these days ... so my complaint is more like why is that other useless junk in the 5000A (HF, Tuner, etc) (haha) KH -Original Message- From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of Dennis Petrich Sent: Saturday, June 27, 2009 10:32 AM To: Ed Helms; flex radio Subject: Re: [Flexradio] 6 meters recieve on 5000 I agree with Ed's comments, I'm looking at a 5k but it bothers me that I will need to add a 6m preamp!!

Re: [Flexradio] 6 meters receive on 5000
With all of the great features of this radio, this is one of the very few shortcomings and it can solved with a $79 preamp from ARR. The 5000A even has the preamp in/out BNC connectors on the rear panel so all you have to do is connect it and check a box in the Antenna dialog box. Even cooler, you can specify the preamp gain, so the S-Meter continues to read accurately (and according to my calibrated HP signal generator, it is accurate to below -140 dBm) when the preamp is enabled. 6M is my favorite band and my 756 ProIII has been very lonely since I got the 5000A. I just added a 2nd preamp to the RX2 input and am putting up a 2nd 6M antenna today so that I can listen on both receivers at once (RX1 on the left ear and RX2 on the right ear). Antenna 1 is 9el at 48' and antenna 2 will be 7el at 95'. I can look for beacons while monitoring the calling frequency or use it for diversity reception when signals are coming in at differing arrival angles. Yesterday, with a single antenna, I was decoding FSK441 on 50.260 (RX2) while listening to the band starting to open on 50.125 (RX1). I could never do that with the 756 ProIII. Also, the noise blanker really works. I've copied Q5 signals that were 4 S-units below the power-line noise. Don't let this one thing stop you from getting a really great radio. I don't think you'll ever regret it. 73, Clay W7CE - Original Message - From: Dennis Petrich radio...@frontiernet.net To: Ed Helms n4z...@gmail.com; flex radio FlexRadio@flex-radio.biz Sent: Saturday, June 27, 2009 7:32 AM Subject: Re: [Flexradio] 6 meters recieve on 5000 I agree with Ed's comments, I'm looking at a 5k but it bothers me that I will need to add a 6m preamp!!

The Flex 5000 has extremely good performance for HF low bands. Flex 5000 would not sell well if it had poor low band performance and there would be no 3000 if that were the case is my short version of my opinions on this matter. The 3000 does NOT equal the 5000 in receiver performance on the low bands. I think most will agree that operating well on 160m-20m is more important to sales than 6m. It takes a very inexpensive preamp for 6m to make it a top performer and it is a complete triviality to hook it into the loop provided on the back of the radio and adjust the operation to automatically use that preamp on 6 and on 6 only.

[Flexradio] Why a 6Meter Preamp Is Needed
The Flex 5000A currently has a noise figure of approx. 16 to 20dB at an MDS of approx. -126dBm..Addition of a low noise figure preamp ($100) can substantially improve the receiver noise figure but is not mandatory for normal operation. My reference rig is the Icom Pro III which has a 6 meter MDS of approx. -142dBm with a noise figure of approx. 5 to 8dB...With an appropriate preamp the Flex can reach this level of performance with a better dynamic range to boot..Other brand rigs have the same problem as the Flex 5000A (ex K3 sells a 6M preamp) when it comes to sensitivity and noise figure.The preamp is only needed if you wish to do weak signal work.. In general one should consider the total system noise figure of the stationOne of the best performance improvements can be had by reducing the feedline losses.Losses in the receiver front end directly reduce the receiver noise figure and feedline affects both TX and RX performance.There are many other metrics one should consider in rig performanceI own several of the top-end rigs and have found the Flex 5000A beats them hands down in overall receiver performanceThe receiver dynamic range (weakest to strongest signal) for the Flex is phenominal..The receiver noise reduction along with the filtering is additionally on par with $10K rigs.

Re: [Flexradio] 6 meters recieve on 5000
Solution 4:, or perhaps a better term Option 4: is to use a 6M transverter. This is particularly practical if you already have one that has the front end and system noise figure that you need and want. It also provides you with the ability to add additional IF radios, SDR or otherwise into the station's configuration. The main downside that I can see is that you will loose the benefits of the precise frequency control/readout/stability of the 5000 since most all transverters are off and/or drift a bit. Though with 6M transverters that is usually not a very noticeable problem. I anticipate that will be the route that I will go with once the Flex-1500's hit the street. I already have all my 6M - 70 cm transverters setup for split RX/TX IF's and am feeding multiple IF (RX) radios for each of my 6M - 70cm transverters already. So I'm currently envisioning at least one 1500 per band, and then perhaps one or two additional (HW) RX's of some description for each of those bands. In my case doing that more or less represents just pulling out the current fleet of Ten Tec Pegasus IF radios and then dropping the Flex-1500's in their place.

Re: [Flexradio] 6 meters recieve on 5000
Also -- Everyone who gets seriously interested in weak signal VHF/UHF operation quickly learns that the ONLY place to put a pre-amp, tailored for each band of interest, is as close to the antenna as humanly possible (usually in an enclosure close to the top of the tower). This allows SHORT runs of *expensive*, LOW loss cable between the antenna and the pre-amp and lower cost, more lossy, runs of cable between the pre-amp and the receiver/transverter in use. No manufacturer can build the kind of performance gain that is provided by this simple add-on into a production radio. PHYSICS rules the game.

Re: [Flexradio] 6 meters recieve on 5000
- Original Message - From: Philip M. Lanese l31ne...@epix.net No manufacturer can build the kind of performance gain that is provided by this simple add-on into a production radio. PHYSICS rules the game. But for 6m a good built-in pre-amp will overcome the lack of sensitivity - as with my TS-480SAT and FT-950. On 2m / 70cms I use external SSB Electronics masthead pre-amps. On 6m loss from decent co-ax is not too significant - I use ~ 8m of aircell 7 at the moment on 6m and the loss is 0.5dB. IMO the complaint about lack of sensitivity is valid - I don't own a new model Flex yet and I sold my SDR-1000, but when I get around to buying a new Flex or other SDR receiver I'll also have to factor in a 6m pre-amp.

The improvements are fantastic in the pan-adapter, power out on 6 meters, overall sensitivity, and the single wire to the computer.

[Flexradio] 160 meter filter RE: F3K Shiptime, comments on Flex-3000
The only downside so far is that it seems to have more images from AM broadcast stations on 160. The 1000 had almost none (especially with the software? filter that was available). If you want a good filter for 160m check this one out. I put one of these BCB filters on my 5000A and it made a big difference. Scroll to the last filter on the page. it was $42.00 well spent. Zack N8FNR http://www.iceradioproducts.com/filtersrf.html BCB Interference Filters AM broadcast stations transmitting in the frequency range from 550kHz to 1700kHz cause havoc with HF and VHF receiving operations, often inducing carriers, modulation, broadband noise and other disturbances into delicate equipment. Such interference can frequently be heard mixing with other received signals in the shortwave bands and commonly overwhelms front ends of modern receivers. Broadcast reject filters reduce AM band signals to levels where local Stations can still be received in most cases, but are no longer threatening to other desired services. A must for serious low frequency DXers or Amateur 160 Meter enthusiasts. Five models are available for both receive-only applications or for use with transceivers (allows transmission of up to 300 watts through the filter above the rated cutoff frequency). Model 401 is for reception only and is designed to notch out the BCB band from 550kHz or 1700kHz, allowing reception of signals below 500 kc and above 1.8 MHz Model 400 units are designed to operate above 3.5MHz These two models are for reception only (400) or transceiving (400X) and, both units place the BCB band frequencies and below well into the stopband, inserting very high attenuation even at the higher end of the BCB band frequency segment. ___ 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/

MixW/WSJT CAT PTT works great. Also, noticed that my K-3 Logikey output, using straight key into the Flex 3K, is a lot smoother.

The QUALITY of the audio coming out of SDR 1.8.1 compared to the TS-570 is like NIGHT AND DAY. Granted I don't have any filters in the Kenwood, but still SDR is also set on 2.4 kHz bandwidth same as stock Kenwood 570. I am blown away by the fidelity from SDR 1.8.1. By fiddling with the AF and AGC-T controls, I have total control and can adjust so that static crashes and background noise are not even noticeable. It's almost like I am listening to an MP3 recording of someone talking, rather than an HF signal across 8000+ miles.

[Flexradio] VAC Config
Greetings. I am trying to get VAC working. I have audio to the laptop, but nothing from the puter to the radio including ptt (and vox). I was hoping to get some digital action this weekend, so any help is appreciated.

[Flexradio] Locking vfo's and declexia or however it is spelled
In playing fd this weekend using two antennas I found it would be nice at times to lock step the two vfo's. With signals and interference comming from all directions having the ability to do that and swap audio from left to right and back or straight mono into both head phones. As far as the delex, could not figure why no e recv wass deaf went so far as to open up the box (I put on the medusa goggles to protect from the kmart special light) so I would not go blind (no blonde jokes please) only to find I had the box turned wrong putting the ant 3 conn where I thought the no 1 ant connector should be. Now that I feel like a moron. Doh!

[Flexradio] RF disappearing on 20 meters during FD
I have the Flex 5000 at our FD site this weekend as the main phone station. One of the other guys who was operating it (and loving it as well...) called me over to see what he was doing wrong. The radio was exhibiting dead band syndrome after a few minutes of idle time. Signals simply disappeared. Pressing the PTT and releasing brought the receiver back to life. I thought it might be an AGC issue, but finally, after rebooting PowerSDR (18.1) and the radio without the problem going away, I reloaded the database and I think that cured it. Anyone see something similar happen and if so, what was the fix? Aside from RF getting into the mike circuit due to a balanced feedline causing problems, the system is working well and many have operated it with good comments. Generally working whatever I can hear. thanks geep wa4rts operating K4CQ in VA ___ 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/
