[Flexradio] Help Button
In my humble opinion, the PowerSDR application badly needs a help button. It has now reached the size and complexity that make it very hard to remember the location of features in the menu structure and steps in the operation processes.

[Flexradio] Those 3 Numbers on the Display's Bottom Right
On the bottom right of the main display in most modes appear three numbers that I can't find explained in the Flex-5000's manual or elsewhere. The numbers are, as I eventually figured out, the frequency of the loudest signal on the display, its strength in dBm and its offset from the radio's center frequency. What is the purpose of those?

Re: [Flexradio] My Rookie Performance in the Recent FMT
http://www.spectracomcorp.com/Portals/0/products/pdf/NetClock_GPS-Model_9283.pdf It has a 10 MHz output, so could be made to work with the 5000a. You might have to adjust level. My thunderbolt was approx 3 dB too hot, so I ran it through a TV antenna splitter to drop 3 dB. It needs a GPS antenna - maybe he has it. Join the FMT-nuts reflector (see www.k5cm.com ) and ask for more there - someone may be using it already. Jerry W4UK At 01:29 PM 10/10/2010, William H.

[Flexradio] N4J operation -- bands lousy, radio great!
I reported earlier that our club would be operating N4J at Thomas Jefferson's Poplar Forest retreat in Forest ,VA this past Saturday, and had asked for the Flex to help train ops and show off a bit. We did show off! The 3000 with 2.0.8 performed flawlessly in SSB and PSK31/Rtty modes (with flDigi). I used an external keyer for CW as I still get some unwanted pauses with the software keyer, but better than it was, and I expect that problem to be solved before long. We worked around 115 stations, mostly 40 meters, as 20 was pretty bad. We held down a spot on 40 for quite some time until I took a breath and paused too long, and the PA QSO party folks swooped in. We worked a bunch of them as well. Went on to work several European Russian stations in another contest, generally getting them on the first shot with RTTY. We ran the radio barefoot into an Alpha Delta fan dipole up about 40 feet, and the internal tuner handled the antenna nicely, only a little touching up needed as it was factory tuned pretty well. The big panadapter display brought in a number of visitors, including one of the staff archeologists who had some broadcast experience. We let her get her feet wet working some of the QSO party stations, and may have a convert -- she had a ball! A good number of our folks who participated operated the station and had fun doing it. All in all, a good day, with lots of good comments from stations worked about the signal strength and the audio quality.

[Flexradio] Interesting IMD?
I was listening to some WSPR up on 30m at around 10.140 MHz this afternoon. A bunch of DX'ers were booming in down around 10.115 MHz, and I was hearing them. They were registering around -60 dBm when I looked at them. Then I stood back and watched the waterfall for a while. Switching in the Attenuator helps a lot, but I noticed sidebands occurring about every 7 kHz both up and down the band. If I inject a strong carrier on my own, then I can make the situation much worse, with sidebands clearly visible from the DX crowd extending as far as 100 kHz above their frequencies. So having a strong signal somewhere in the A/D passband is a clue. In AM mode I also noticed that I was hearing a strong B'cast station down around 9.95 MHz, and sometimes WWV at 10 MHz too, all up at 10.140 MHz. Now the B'cast and WWV I can understand as due to pre-D/A self mixing in the receiver front-end, since they weren't even in the passband of the D/A. But the other stuff, and that curious spacing of sidebands at 7 kHz intervals really has me puzzled. What in the world would cause this sideband formation? I can think of no Post-A/D digital algorithms in the chain that would cause it. The signal levels going into the D/A were down around -40 dBFS (is that an overall peak level across the entire 96 kHz?), so there should be no clipping going on. Is this an artifact of Tayloe mixing? On a more conventional receiver these images do not appear. Dr. David McClain Chief Technical Officer Refined Audiometrics Laboratory 4391 N.

[Flexradio] RF Problems with a Flex 5000
A friend (KC5PD) and I (KF5U) each purchased a Flex 5000A on the same order. The radios were identical from the factory, shipped at the same time, and they both included the ATU and the 2nd receiver. We are both running PSDR v1.18.6. From the beginning, KC5PD has been having a serious RFI problem with his rig, while I have not had even a single RFI problem with mine. He is using a Heil mic connected thru the front of the F5000, while I am using a Heil PR-781 mic connected to the balanced input on the back of my Flex. As an experiment, KC5PD brought his F5000 to my shack today so we could run some tests. First, we connected his mic through the front input on my rig. He had SSB QSO's on 17m and 20m with several hams with no RFI problems whatsoever. Then we simply disconnected my F5000 and connected his F5000 in its place. Nothing was moved. Except for replacing my F5000 with his, everything else remained identical - same antennas (cubical quad), same power supply, same computer, same firewire cable, same speaker cable, etc. Same everything. He even sat in my chair!! In trying to talk with the hams we did previously, KC5PD immediately had very serious RFI problems, where we had no RFI problems minutes earlier using my F5000 with the same mic connected to the front. We then connected my mic to the balanced I/P on KC5PD's F5000, and the RFI problems disappeared. In summary, with both rigs at my QTH: 1. I have no RFI problems on my rig whether I use the balanced I/P with my mic or the front mic connector with KC5PD's mic. 2. With KC5PD's F5000 at my shack, he has serious RFI problems with the mic connected through the front I/P. 3. With KC5PD's F5000 at my shack, he has no RFI problems with the mic connected via the balanced I/P. Thus, there is some sort of significant RFI problem with KC5PD's F5000 when he uses the front mic input. In an identical configuration using his mic and his mic cable, I have no such problem. (His mic cable has been properly grounded per Dudley's and Heil's recommendation.) As an interesting side note, the serial # on his rig bears absolutely no relation whatsoever to the serial # on my rig, even though they were on the same order and were shipped together. I don't know what this means, but it seems odd. Any comments or suggestions would be most appreciated, as KC5PD has about exhausted his Flexibility in trying to get a resolution to this problem.

Re: [Flexradio] RF Problems with a Flex 5000
JD, Sounds like some good diagnostic work going on here.. Many times RF, is in the shack and it can cause a wide variety of issues, and sometimes this is really hard to describe to another party, unless they are hearing it themselves. Sometimes it's just low rumbles, to high pitched whines, to echos , or maybe noise burst, and this can vary band to band.. Have PD call me sometime tomorrow, we'll get it worked out, kind of sounds like Ed and maybe Gerald need to dig into it. So you know, there is a small PC board soldered to the rear of the front mic connector that has some bypassing on it, it has not given any issue, but maybe a problem here, not sure until Ed gets to look at it on the bench.. 73, Dudley WA5QPZ FlexRadio Systems (512) 250-8595, Option 2 Email: dud...@flex-radio.com Web: www.flex-radio.com Tune in excitement! ™ On Sun, Oct 10, 2010 at 9:54 PM, J D Lambright jdlambri...@the-law-offices.com wrote: A friend (KC5PD) and I (KF5U) each purchased a Flex 5000A on the same order.

Re: [Flexradio] RF Problems with a Flex 5000
Dudley, Thanks for the prompt reply. If you recall, I met you and Bob at the Belton Hamfest last weekend. PD and I were listening on the Flex net today, but you are too close to us for a QSO on 20 meters. We tried to relay via one of the guys you were talking to so he could have you call us on the phone, but you were apparently away from your rig at that time. As you can tell from my note below, I have no RFI problem with mine at all, even when I turn on my Drake L7 amp. If you simply disconnect my rig and put PD's in its place, the RFI problems make his rig unusable, even barefoot. Flex just shipped it back to him a few days ago, but unfortunately the problem is still the same. I think our experiments today clearly show that the problem is in his F5000, and it shows up when the mic is connected via the front panel. The exact same mic and mic cable work great on mine when connected in the same fashion. J D Lambright Law Offices of J D Lambright Conroe Tower, Suite 450 300 W.

Many times RF, is in the shack and it can cause a wide variety of issues, and sometimes this is really hard to describe to another party, unless they are hearing it themselves. Sometimes it's just low rumbles, to high pitched whines, to echos , or maybe noise burst, and this can vary band to band.. Have PD call me sometime tomorrow, we'll get it worked out, kind of sounds like Ed and maybe Gerald need to dig into it. So you know, there is a small PC board soldered to the rear of the front mic connector that has some bypassing on it, it has not given any issue, but maybe a problem here, not sure until Ed gets to look at it on the bench.. 73, Dudley WA5QPZ FlexRadio Systems (512) 250-8595, Option 2 Email: dud...@flex-radio.com Web: www.flex-radio.com Tune in excitement!

The radios were identical from the factory, shipped at the same time, and they both included the ATU and the 2nd receiver. We are both running PSDR v1.18.6. From the beginning, KC5PD has been having a serious RFI problem with his rig, while I have not had even a single RFI problem with mine. He is using a Heil mic connected thru the front of the F5000, while I am using a Heil PR-781 mic connected to the balanced input on the back of my Flex. As an experiment, KC5PD brought his F5000 to my shack today so we could run some tests. First, we connected his mic through the front input on my rig. He had SSB QSO's on 17m and 20m with several hams with no RFI problems whatsoever. Then we simply disconnected my F5000 and connected his F5000 in its place. Nothing was moved. Except for replacing my F5000 with his, everything else remained identical - same antennas (cubical quad), same power supply, same computer, same firewire cable, same speaker cable, etc. Same everything. He even sat in my chair!! In trying to talk with the hams we did previously, KC5PD immediately had very serious RFI problems, where we had no RFI problems minutes earlier using my F5000 with the same mic connected to the front. We then connected my mic to the balanced I/P on KC5PD's F5000, and the RFI problems disappeared. In summary, with both rigs at my QTH: 1. I have no RFI problems on my rig whether I use the balanced I/P with my mic or the front mic connector with KC5PD's mic. 2. With KC5PD's F5000 at my shack, he has serious RFI problems with the mic connected through the front I/P. 3. With KC5PD's F5000 at my shack, he has no RFI problems with the mic connected via the balanced I/P. Thus, there is some sort of significant RFI problem with KC5PD's F5000 when he uses the front mic input. In an identical configuration using his mic and his mic cable, I have no such problem. (His mic cable has been properly grounded per Dudley's and Heil's recommendation.) As an interesting side note, the serial # on his rig bears absolutely no relation whatsoever to the serial # on my rig, even though they were on the same order and were shipped together. I don't know what this means, but it seems odd. Any comments or suggestions would be most appreciated, as KC5PD has about exhausted his Flexibility in trying to get a resolution to this problem.
