Actually, I think that if you look at the version of PowerSDR being used by the HPSDR/Apache community, it branched off from the Flex version some time ago and the changes that Flex makes are not appearing in the HPSDR version. Likewise, the changes that the HPSDR community is making are not making it into the Flex version. So they are really two different programs now. One can certainly argue which one is better but it seems pretty clear that they are different and both have advantages and disadvantages relative to the other.

That is probably not going to happen because the 1500/3000/5000 work very differently than the 6000 series. The former require the PC to do the DSP while the DSP is performed inside the 6000 series hardware. All the PC does is provide a front-panel display. This makes it easier to write programs for other platforms. But it means that the software architecture is WAAAY different and not applicable between hardware families. > They are probably spending a fortune trying to support 2 software > products (one of which they are making nothing on). Not entirely. Sales of the 1500 and 3000 support the continuing development of PowerSDR. But I do agree that Flex is going to be planning a replacement for these radios and when they do, you can bet that Flex will stop developing PowerSDR. Until then it will be business-as-usual. -- Brian Lloyd, WB6RQN/J79BPL 706 Flightline Drive Spring Branch, TX 78070 br...@lloyd.com +1.916.877.5067 (USA) ___ 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.flexradio.com/ Homepage: http://www.flexradio.com/

They need to be competitive. If they are not competitive then the question is why? Personally I like that there is competition. I believe in a free market economy as it favors the consumer (that's me in this case). Also the proliferation of very high performance DDC radios is going to get the attention of the big boys, meaning even better options for me.

If you are not running or listening to AM you can set the IF to zero and the display will be centered.

Not so fast. What it means is that if you, as a ham, buy one, the manufacturer claims its emitted signal quality meets FCC signal purity requirements. Of course, you are on the hook to ensure emitted signal quality but this suggests that it might be reasonable for you to assume that it does so right out of the box. Of course, Caveat Emptor. YOU are on the hook for the signal quality. OTOH, YOU are on the hook for the quality of your emitted signal anyway. (And looking at the CW signals coming out of some Yaesu rigs, it is clear that not a lot of people actually check the quality of their emitted signal. :-) > Certification allows the device to be sold, imported, listed for sale or > manufactured in the USA. Are you sure about imported? Certainly they can't sell them to HRO or AES to be resold in the US, but what law prevents me from buying a radio outside the US and bringing it in to use on the ham bands? I am on the hook to ensure that the emitted signal meets, "best accepted engineering practices," but that is about it. > You will note when Icom, Kenwood etc. release a new radio a statement will > be issued with the advertisement something to the effect " not for sale > pending FCC Certification", the print is small but its right there on the > page in QST. > > So my question, does anyone know if Apache Labs has met FCC certification? > And perhaps the next real question is, "Does it matter?" As far as I can tell, Apache Labs is not selling their products in the US. They are selling them in India via website and if you choose to buy one and then import it to the US, well, that is your lookout. So the key is the difference between selling and using. There is nothing in the rules that says that hams have to use equipment that has received FCC type certification. If there were, we could not legally home-brew equipment. So, does that mean that you can buy a radio from Apache Labs, have it shipped to you, and then use it freely in the US? I don't know of anything in the law that would prevent you from doing so but I am not well versed with international trade law nor do I play an attorney specializing in international trade law on TV. OTOH, if you buy one, put it on the air, and your signal nets you a pink slip, you can't blame the manufacturer. -- Brian Lloyd, WB6RQN/J79BPL 706 Flightline Drive Spring Branch, TX 78070 br...@lloyd.com +1.916.877.5067 (USA) ___ 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.flexradio.com/ Homepage: http://www.flexradio.com/

Apparently they store the enumeration (channel number) rather than the channel name even though they LIST the channel name. Unfortunately the channel number changes whenever there is a change in the number of audio channels. So if you plug in a USB headphone or microphone, WSJT and WSPR will stop working until you reconfigure the audio channels. I solved the problem by *always* reconfiguring the audio channels whenever I start WSPR. So, even if the configuration of WSJT or WSPR *looks* right, it may not be.

Re: [Flexradio] TOO DAMNED MUCH
Actually, I lay the bulk of this problem at the feet of the "digest" option. It means that, you get many messages as a single email message and when you press the reply button, you get many messages included in your reply. Given that every current mail user application (MUA) "threads" messages (combines all the message on a single topic together in a "thread"), there really is no need for the digest mode. So, at the rist of being annoying to the users of the digest mode, I would suggest that they are their own worst enemy by continuing with the digest. Switching back to the standard of individual messages and then letting their MUA deal properly with messages on a common topic would go a long way toward eliminating their problem. I know that when I see a message come with a subject of "Flex Radio Digest" I know that it is going to contain about 1% useful information and 99% of messages that were included that have nothing to do with the topic. (Not to mention that the subject field no longer contains useful information that would allow me to know what the topic of the message is.)

Sure you do. Double check it against WWV. If it is within 1/2 Hz, the Rb is locked and all is well.

It is a question of what is the job you are trying to do. It is useful to understand the differences. Certainly the long-term stability of the GPSDO is better because the reference oscillator is always being corrected back to the correct time, i.e. long term number of cycles. But in the short term, variations in the GPS satellite geometry can cause the GPSDO to exhibit short-term frequency errors. Of course, long-term these are corrected back out but if one was comparing one would notice small short-term variations in the frequency of the GPSDO while the RbO showed more stability. So the question is, which is more important? Of course, could could have a GPS-disciplined Rb reference. Now you get the best of both worlds, i.e. dead-nuts accurate long term stability with outstanding short-term stability. And the other thing that many people seem to forget about is the phase noise of the disciplined reference oscillator. That may have substantial effect on the performance of the receiver over and above the frequency accuracy. So, when it comes to the question of, "which is better, an Rb reference oscillator or a GPS disciplined oscillator," the answer is a resounding, "it depends." I still hold that, for most people looking to increase the frequency stability and accuracy of their Flex 1500 or 5000, an Rb reference like the LPRO-101 is simpler for the following reasons: 1. No outside GPS antenna needed. 2. The LPRO-101 runs on a single 19V supply (I use an old laptop power supply) while the Thunderbolt needs +5V, +12V, and -14V.

Re: [Flexradio] DIY 10 MHz sources for putting Flex 5000A "DEAD ON" orreally close

The average Rb reference oscillator is more accurate even when "uncalibrated" than most people have ability to measure. Once the unit achieves initial lock it is already better than 5e-8 (0.5Hz at 10MHz) and headed for something on the order of 3e-11 (less than 1 millihertz at 10MHz). After all, the total adjustment range is only +/- 0.015 Hz at 10MHz. So I think that, even for people trying to win the FMT, an uncalibrated Rb reference is going to be good enough. And here's a hint: that error is less than the tuning error in the Flex radios on most frequencies. > Not so with a GPSDO. Again, you have to understand the nature of the beast. The Rb reference usually has better short term stability than the GPSDO. Of course, the GPSDO has better long-term stability because it is being corrected over time. But for ease-of-use, it is really hard to beat the Rb reference. (I have and use both.)

Normally they are hidden under the noise but if you plug in a dummy load or are in the higher bands where all is quiet, they become apparent. Spur Reduction keeps them out of the passband but they are apparent on the pan display or the waterfall. If you turn off spur reduction then you might get one in the passband. I know that it bothered me a bit at first but I eventually realized that pretty much all radios have 'em, you just can't see 'em, and they don't interfere with the good performance of the radio. The new crop of DDC/DUC radios like the Flex 6000 series won't have them as there is no DDS LO. I'm definitely looking forward to the arrival of my 6700.

The fix is to reset the database, not reinstall the software. (Which does work as you have found but is like using a bomb to swat a fly.) My solution is to start with a clean database, do all my configuration, then save a copy of the current database which I then set aside.

You introduce latency twice, by buffering at the the input to a DAC (speaker/headphone output at the radio) and at the output of an ADC (output of a sound card in your computer), but only once with VAC since you eliminate the back to back DAC-ADC path. But that doesn't mean you can't make things worse by poor configuration. :-) Still, the preferred approach is to use VAC to transport the digital data from your "radio" (PSDR) to the application, e.g. fldigi. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 br...@lloyd.com +1.767.617.1365 (Dominica) +1.916.877.5067 (USA) ___ 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.flexradio.com/ Homepage: http://www.flexradio.com/

Therefore a preselector early on in the receiving chain is very useful, especially if the rest of the radio is prone to IMD.

As long as you can hear > band > noise drop when you disconnect the antenna you have plenty of sensitivity. > The advantage of a preselector is not that it provides more gain, but that it reduces the power of undesired signals at the input of the receiver. Whenever you pass two signals through a nonlinear device, and that would be any amplifying stage, any mixer, any detector, you get intermodulation products. As you pass more of these signals through, they all intermodulate together. In fact, if you have really strong signals, the intermodulation products can themselves intermodulate with signals and other itermodulation products. The result is spurious products all thought the receiver. And even the noise power can be intermodulated up to the receiver's passband resulting in a higher noise floor. The earlier in the receive chain you can reduce or eliminate unwanted signal and/or noise power, the better your receiver will perform. In the olden days, most receivers had decent preselection as a way to eliminate images. Eliminating lots of unwanted signal power was an unlooked-for side effect. Then we got broadbanded receivers that upconverted and didn't need preselection in order to eliminate images. And these receivers even tested well ... on the bench where only a few signals came in the antenna port. But once you plugged in a real antenna, especially one that was relatively broad-banded, and all that cruft came in and intermodulated with everything else, you got crappy receiver performance. Now there seems to be some idea that SDRs suffer more from this problem than do other receivers. This is not the case. In fact, since SDR does conversion to digital early in the receive chain, they are LESS susceptible to this problem. The DDC/DUC (direct conversion) SDRs like the new Flex 6xxx series is going to be even LESS affected by front-end and first-mixer IMD. (In fact, as long as the ADC is not clipping, the DDC/DUC radios should should be darned-near textbook perfect in their response and behavior.) But in the mean time we have radios like the 1500, 3000, and 5000. They will benefit from preselection, to a greater or lesser degree, depending on the amount of unwanted signal power arrives from the antenna. The greater the crap (technical name for unwanted signals) coming down the feedline, the more a preselector will help. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 br...@lloyd.com +1.767.617.1365 (Dominica) +1.916.877.5067 (USA) ___ 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.flexradio.com/ Homepage: http://www.flexradio.com/

Well done! While many argue from opinion, you demonstrate. But I would like to make one point here -- that it doesn't matter whether the radio is an SDR, hybrid, or pure analog, if you remove unwanted signals before they get to the active stages, the receiver will work better. Period. So, if you are dealing with strong, unwanted signals, you should remove them in order for the receiver to perform its best.

If they used good coax then the SWR and line loss numbers will be that of a good piece of coax. The choking impedance from 160m-10m is the crucial information. The bigger that number is at your operating frequency, the better it will choke off currents on the outside of the line. One thing to consider is that, if the impedance is too low, the choke will run hot and NOT do the job you want it to do. And one other thing. Where you place the choke in the line makes a difference. RF current appears in standing waves just as RF voltage appears in standing waves. There are points on the line that are high current (low impedance) and points that are low current (high impedance). If you happen to place your new choke at a high-impedance point on the line, the effect will be minimal. If you place it at a low impedance point on the line, the effect will be maximal, i.e. reducing current all along the line. If you have a way of measuring RF current along the line you can find these high current nodes. And measuring current on the outside of the line is surprisingly easy. Put a ferrite bead over the coax and wrap several turns of hook-up wire around it too. You have just made a current transformer. Connect a meter that will measure RF voltage to the free ends of the hook-up wire and now you can find the current peaks and nulls on the coax. (It doesn't matter if it accurately measures current, only that it will show you where the peaks and nulls are.) > My friend in a QSO last night suggested the MFJ-915. This item is only > 29.99.

You have no idea what kind of ferrite beads were used so you have no idea how much choke impedance there is. You are shooting in the dark.

SWR has nothing to do with SWR in the shack and what Tim said, RF on the outside of the coax has EVERYTHING to do with RF in the shack. RF current on the outside of the coax can come from two places. It can be conducted from the antenna or it can be picked up from being in the near-field.

But that still won't deal with common mode currents and you still need the common-mode choke. It is just that building a common mode choke for balanced line is MUCH more difficult than building one for coax. In that case it is easier you put the common mode choke between the tuner and the rest of the station. BTW, you can also use a current choke/common-mode choke to turn an unbalanced tuner into a balanced tuner.

[Flexradio] Using the new MacBook Pro with the Flex 3000 and 5000
I just acquired a new MacBook pro with the "Retina" display. I actually took a chance that it would not work with my 3000 since the MacBook Pro with the Retina display does not have a native FireWire port. All it has are USB-3 and Thunderbolt ports. We know that FireWire-to-USB adaptors do not work so I did not expect that the FireWire-to-Thunderbolt adaptor would work either. Regardless, I loaded up Windows7 (32-bit -- nothing I run is 64-bit) and took a shot at it. I must admit I was pleasantly surprised that, not only did it work but it worked really well. Not a single DPC glitch the entire night. So, if anybody is hanging back from getting a new MacBook Pro because they are worried that it might not work with a 3000 or 5000, I can put your mind at ease. It works very well using the Apple FireWire-to-Thunderbolt converter. Oh, and the 2880 x 1800 pixel display is amazing ... assuming you have a magnifying glass. PowerSDR takes up less than 1/4 of the screen in native resolution. You can get ALL your programs on the screen at once, and that is on a 15" display. OTOH, you really MAY need a magnifying glass to read it. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 br...@lloyd.com +1.767.617.1365 (Dominica) +1.916.877.5067 (USA) ___ 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.flexradio.com/ Homepage: http://www.flexradio.com/

Very few Noise Blankers work properly with very strong signals. Remember that they blank when a signal reaches a certain threshold and a really strong nearby signal could reach that threshold, causing blanking of the desired signal. I would not expect the NB to work on the AM BCB due to overload from other strong signals in the receive span.

Re: [Flexradio] Need AVC
Guys, this is what AGC is FOR. Older radios that had AVC used it because AGC did not work well. (ANL was just a clipper and a way of dealing with impulse noise in an AM receiver, taking advantage of how clipping the peaks greatly reduced the average power of the noise.) The trick here is to use the AGC-T opposite the way that Flex suggests that it be used. Most of us prefer the first 10dB or so to be linear so that a 10dB change in signal level translates into a 10dB change in audio level. If you do that and push the noise down, it works almost as well as DSP-based noise reduction (NR) but without the "gargles" and other anomalies (which drive me nuts). The point of AGC is to flatten the level response so that stronger signals do NOT sound different in level. Certainly the AGC in the Flex radios is pretty good. So here is what I suggest: rather than adjusting the AGC-T downward until you get a clear and subjective halving of the noise floor level (about a 10dB cut), I recommend you slowly increase AGC-T until you no longer hear an increase in noise level. You want your AGC threshold set right at the noise floor. This should keep everything, noise and signal, at that level. I don't like this setting because it means that I have to listen to the noise at the same level as the signal between and words (in SSB and depending on AGC speed), but it does mean that you should hear the really weak ones at the same volume level as the really strong ones. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 br...@lloyd.com +1.767.617.1365 (Dominica) +1.916.877.5067 (USA) ___ 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.flexradio.com/ Homepage: http://www.flexradio.com/

But you did define TWO virtual cables, didn't you? You need virtual cable 1 and virtual cable 2, one for RX and one for TX. You cannot use the same virtual cable for both. Remember, a virtual cable works just like a wire. You cannot wire both input and output to the same wire and expect everything to work.

Flex does not give specific numbers for protecting against damage but I would not even remotely consider putting anything more than 0dBm into it and probably not more than -10dBm. So, you need a 30dB pad between the output of your TX and the input of the 1500. Also, the 50 ohm input impedance of the 1500 in parallel with the 50 ohm impedance of the dummy load would present a 25 ohm load to the TX or about a 2:1 SWR.

Re: [Flexradio] Flex Logging Software
The simplest approach to getting logging going is to install and use fldigi. It may not be the best way but installing fldigi and setting it up to make it work with PowerSDR gets you 99% of the way there. You get the digital modes and you get a decent logging program. It may not have all the features of the other programs but it has the features that most people need. It is, IMHO, the best place to start and gain experience. Once you have that working for awhile you can then determine what additional features you need, if any, and then go looking for them. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 br...@lloyd.com +1.767.617.1365 (Dominica) +1.916.877.5067 (USA) ___ 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.flexradio.com/ Homepage: http://www.flexradio.com/

Remember, every time you change amplitude, frequency, or phase, you get modulation sidebands. I am not sure what you mean by "tails". If you are seeing many spectral lines other than the carrier at time other than when JT65 is switching tones, you may be overdriving the TX audio section. Start by setting the TX meter in PSDR to read mic level. Make sure that the mic level (actually the audio input level) never exceeds 0dB. I normally set VAC TX gain to produce -1dB for MFSK modes like JT65, WSPR, Olivia, MFSK-16, etc. For PSK31 or other digital modes that have a significant amplitude component I use -2dB or -3dB to ensure I have headroom and won't clip the signal in the audio stages. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 br...@lloyd.com +1.767.617.1365 (Dominica) +1.916.877.5067 (USA) ___ 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.flexradio.com/ Homepage: http://www.flexradio.com/

It appears to be a failure of Wide Band Image Rejection (WBIR) in PowerSDR. It seems to occur a little bit each time you band switch. The short-term solution is to shut-down PowerSDR and start it back up again.

But using a high-pass filter on the audio passband is fairly common with FM transceivers. Most repeaters do not transmit their CTCSS tones. Some do. And in some cases the CTCSS tone transmitted by the repeater is not the one necessary to open the squelch on the repeater's receiver. On some FM receivers a CTCSS tone is obvious, especially the ones higher in frequency. So, yes, Flex could make a tracking audio notch filter but that is quite unusual. In the mean time, have you tried using the 10-band EQ? ;-) -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 br...@lloyd.com +1.767.617.1365 (Dominica) +1.916.877.5067 (USA) ___ 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.flexradio.com/ Homepage: http://www.flexradio.com/

These appear on either side of every spectral line, including those produced by IM in the exciter (and every amp has IM). These sidebands can be considered new distortion products because they are not part of the original signal and they are not desired either. Also consider that ALC does not respond instantaneously. There will always be a couple of milliseconds of overshoot while the amp generates the ALC signal and then more for the exciter to respond to it. So, while popular, ALC between amp and exciter does not appear to me to be particularly desirable. I sure as heck wouldn't trust it to protect my amp. I would want a protection system that would shut down the amp in a fault conditon, not just reduce the drive.

If you are so unhappy and convinced that Flex has done all this with malice of forethought, then you really have no option but to report them and/or bring a suit against them. Otherwise, I think you would do well to stop posting lest they decide to bring suit against you. And in case you are having difficulty understanding me, what I am saying in simple words is, "Put up or shut up." Actually, you strike me as just another troll and the best solution is to just ignore you. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 br...@lloyd.com +1.767.617.1365 (Dominica) +1.916.877.5067 (USA) ___ 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.flexradio.com/ Homepage: http://www.flexradio.com/

I guess the major question is, "What is your point?" What is it that you hope to accomplish? Are you hoping to punish Gerald? Are you hoping to hurt Flex somehow? Are you hoping to "help" the rest of us who are too stupid to realize how malevolent/stupid Flex is? We are all big boys (and girls) here. Many of us have owned Flex products. We are walking into this with our eyes open. I know that I don't really need your help in this area. I am well aware of what has been promised and what has been delivered. I even have a pretty good idea what was and is wrong. I understand why Flex never delivered on its rewrite of PowerSDR and I also understand why Flex has stuck with PowerSDR even given its limitations. I also understand how the new architecture of the 6x00 series is different and how that is going to change how they develop software for it and why that is likely to produce a product that is far more flexible and extensible than their previous products were/are. I guess what I am saying here in a nutshell is, "Thank you for your concern but I don't really need your help." -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 br...@lloyd.com +1.767.617.1365 (Dominica) +1.916.877.5067 (USA) ___ 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.flexradio.com/ Homepage: http://www.flexradio.com/

If you aren't sure, go to the Flex website store and you will see that you can still buy a Flex 5000a. It is right there on the front of the web site with a "Buy Now" button still prominently displayed. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 br...@lloyd.com +1.767.617.1365 (Dominica) +1.916.877.5067 (USA) ___ 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.flexradio.com/ Homepage: http://www.flexradio.com/

That should make the problem go away for awhile. It helps a lot if the radio has a strong signal to calibrate WBIR against otherwise it ends up with compromised image rejection. Typically 6m doesn't have a lot of strong signals so WBIR can get lost in the weeds. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 br...@lloyd.com +1.767.617.1365 (Dominica) +1.916.877.5067 (USA) ___ 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.flexradio.com/ Homepage: http://www.flexradio.com/
