[Flexradio] Antenna switch
I use a coaxial relay with the de-energized side going to a dummy load and the other to multiband hf antenna. The relay is powered by a wall wart that is plugged into one of the sockets on my Ethernet power controller. I live near Houston and my remote station is 50 miles west of Fort Worth. I check for thunderstorm activity on the Internet before activating the remote antenna. Works great.

Re: [Flexradio] Flex Open Source Software Development
Russel KF1K, I could not find your e-mail address; hope you see this. As soon as Flex (wisely) stopped providing SVN access I requested and received the complete source for 2.0.6 and successfuly built it. There were a few minor problems but it came up after they were fixed. All I wanted to do at that time was to change the upper rx frequency limit of the 1500 to 62 MHz so I could listen to some tv video carriers. That simple change worked great. I think you just send an e-mail to g...@flex-radio.com (or something like that) and they will send an archive of the files needed to do the build. I am now waiting for the first non-beta version of v2. and then I'll get that compiling. It's not quite as handy as the old svn access was but only added a 1/2 hour or so of work to get it going. When v2 is released you should be able get it all working easily. Of course I'm sure v2.0.16 could be gotten now also. I am just waiting until they get it all ready for prime-time. 2.0.16 works nicely on my 1500 and 3000 (even at the same time). I've not tried it on my sdr1000's but my son, KD5IIU, will shortly. Please post your results on flexedge because there are a few others that may be interested. Using Flex sdr's since sdr-1000 serial #1 in 2003. Flex is a great company; super people and products! I'm now using: sdr-1000 x 2 flex-1500 great radio; it's been WSPRing for several months now. flex-3000 also great (except for the low range atu; I use an at-100proII to tune my marginal antenns). flex-5000a hopefully soon (when my sweet wife approves my $5000 request) PowerSDR v2.0.16 happily working on several machines ...

[Flexradio] Those 3 Numbers on the Display's Bottom
Jeff, As you suspected, the cyan numbers on the right represent the delta freq, the amplitude of the largest signal, and the frequency of the largest signal. They represent the entire window width, not just the selected bandwidth. There is also another set that appears on the left side when the cursor is in the window. They represent the same values for the cursor point instead of the largest signal. If the cursor is in the waterfall area, the value changes to the time in seconds since the current time. The numbers are quite handy for making measurements and have been there since before PowerSDR replaced the old VisualBasic Console. They are described in the latest flex-1500 and flex-3000 manuals, chapter 5, section (9), under the heading Cursor and Peak Position Information.

Re: [Flexradio] Couple questions about OptionWindow Filtering Algorithms
The windowing functions only change the shape of the signals in the display. You will not hear any difference between them since they are only applied to the display. It can only be seen. They really have nothing to do with noise reduction. See p 102 in the current manual. If you tune to a very large signal you can see the effects when cycling thru the various types of window functions. For in the noise signals the rectangular works fine, but as the signals get larger, so does the spill over. Some of the functions are narrower than other but at the expense of having bleed out 40 dB down or so, The Blackman-Harris types are wider at the peak but the spillover will normally be below the noise floor.

[Flexradio] Faros/Rocky/sdr-1000/fa-66 ...
Notes on using Faros 1.2 with sdr-1000 and fa-66 audio. You can use Faros 1.2 with your sdr-1000 if you are using the Edirol fa-66 sound device. First set the fa-66 and sdr-1000 up for 96000 Hz sample rate. Go to 14.100 CWU with CW Pitch set to 600 Hz. Turn off SR (Spur Reduction). Also make sure that the DDS IF is set to the default 9000 Hz. I am using the Beta 1.9.1 release although I'm certain this would work with newer SVN's. My setting for Audio:Sound Card:Buffer Size was 1024 and DSP:Options:Buffer Size was 2048 for these tests. Bring up Faros 1.2 and make sure it is paused. Go to Settings:Audio and select EDIROL FA-66 In 2 as the Audio input device. Set the samplling rate to 96 kHz and select I/Q (Right/Left channels). Set the CW Pitch to 600 and the Audio IF to 9600 (not 96000). Start Faros and it should all come up running. For a warm feeling that you have it correctly set, tune the sdr-1000 to WWV and make sure that the carrier is centered on the Faros waterfall display. Then tune back to 14.100 for the NCDXF beacons. You can also set Faros 1.2 up to drive the CAT of the sdr-1000 to have it automatically switch beacon frequencies. Use the ts-2000 setting on both the sdr-1000 and Faros. The virtual serial port, VCom, works fine here. The neat thing about this is that it needs no wires or VAC. Faros 1.2 does not do well with VAC due to some kind of problem in VAC. With the above setup, the delay correction in Faros is only about 20 ms to bring the short path hits in a nice grouping. Using VAC the delay was considerable and the timing was very messed up. Rocky 3.32 can also be used in a similar fashion with the sdr-1000 being used as a fixed frequency setup and Rocky doing the tuning. Since this setup is so simple, it would be really great if Rocky and PowerSDR could exchange information via some, as yet undefined, link. With the same sdr-1000 settings as above, tune the sdr-1000 to the 'rock' frequency that you want. In Faros Settings:Audio select EDIROL FA-66 In 2 again at 96 kHz and select Left/Right = Q/I. Then in Settings:DSP select Single Band and your 'rock' frequency - 9600. For the 14.100 MHz setting on the sdr-1000, set Rocky's Local Oscillator to 14090400 Hz. Set the CW pitch to 600 and Upper for the CW Sideband. You can now use the beautiful Rocky displays to tune around the fixed sdr-1000 frequency. I hope I didn't miss any details; there are a lot of settings. Enjoy! Richard W5SXD -- next part -- An HTML attachment was scrubbed...

What changes were made to the internal (non software) bandpass filters on the FLEX-5000? A. First, all filters are low pass instead of band pass. We don't need band pass filters in the FLEX-5000 SDR architecture. Also, the transmitter and both receivers have their own independent filter banks. Nothing is shared in the FLEX-5000. The acid test for any RX here in Europe is its large signal behavior. I know of no RX with a Scheunentor frontend which survives this test.

[Flexradio] rebuild?
What several folks seem to not know is that C# is not the same as C. In fact, the difference between C# and C++ is almost as great as the difference back to Visual BASIC 6. The IDE from Microsoft is what really brought PowerSDR over so quickly from Visual BASIC. The C++ IDE is no where near as good and to go back to it would be a big mistake. Eric has done a superb job of porting the VB stuff to C# but I'm certain he will agree that this could not have been accomplished anywhere near as quickly with any C or C++ IDE known at this time. Jim Lux mentioned earlier that Microsoft has been able to provide student versions of the IDE for a very reasonable price. This, to me, would be the best avenue to use to get everyone on board. Lets not change platforms every few years so we can have time to enjoy inventing a better radio. Richard W5SXD

Re: [Flexradio] Compiling with VS 2005
Cecil, Changing development software in the middle of a large project is a pretty dangerous thing to do. The main problem is that while some piece of code may compile correctly it may not work exactly the same way as with the old development environment. Because, in a project like this, most code only gets thoroughly tested shortly after it is written, it is less likely to get a good test when upgraded to the new dev environment. And the guy that wrote it will probably not be the one that tests it. Minor changes can have far reaching effects. Changing the development environment is a major change especially with Microsoft. While the C compiler itself has been fairly stable for quite a while, Microsoft makes pretty big changes evey product cycle. You have bitten off a large chunk of work which, by the way, is greatly appreciated. I would try to stay with whatever is blessed by Flex- Radio that is now .net 2003 ...

Re: [Flexradio] Silly VAC Question
Ken, My HP mobo RealTek sound went away on several systems as soon as I installed the delta44. Simply going into the bios and reenabling it worked each time for me. As far as multi-applications using the vac, I am running MixW and PSK31 Deluxe and my own spectrum analysis program all at the same time being driven by an sdr1000. So parallel destinations appears to work ok from a single source, at least for up to three sinks. Richard W5SXD Ken Chong [EMAIL PROTECTED] wrote: (02/28/2006 21:01) Hi gang, I just wanted to thank everyone for their input on the missing integrated soundcard on my ASUS MB. I have a different ASUS system that did allow the Delta 44 to become the second sound card. The newest one shows in the BIOS that the AC-97' codec is active, but the sound card is still missing in action after installing the Delta44. One clue is that the Realtek Sound manager is missing inside its folder. I ran the Utility Disk a couple of times to reinstall the Realtek drivers for the integrated soundcard chipset. Everything is there in the AC-97 folder, but the Sound manager folder is empty. I will try to manually install the sound manager to see what happens. The machine also reported an interupt error too, so I might need to change PCI slots for the Delta44. If I cannot get my integrated soundcard to return, I guess I will plug in my second Delta 44. Patrick's MultiPSK does not want to work under VAC, and keeps telling me that some other application is using the VAC. Another PSK63 app using the PSKCORE.DLL does not sound very clean with a flutter in the audio despite a 11025 sampling rate. HRD and PSK31 deluxe work great under VAC, but DominoEX is a disaster. DominoEX keeps freezing up , and forces me to reboot the machine to make it go away. What a pain...eh?

Re: [Flexradio] VAC flexibility for different digital mode settings
Tim, I agree completeky but I don't think you went far enough. The selection should probably be keyed on the object external application and not the mode of the radio. I find my self with two or three sstv programs, two or three rtty, and several cw decoders. It would be nice to be able to pull these up by application. In addition, I've been running different applications for the same mode simultaneously driven by the single sdr1000 vac source. This could be done so that it would allow the user to configure the sdr1000 for his external applications rather than limiting the choice to two or three sdr1000 modes. Eliminate the DIGU/DIGL buttons alltogether and make then into a user definable drop down menu selector. Regards, Richard W5SXD Tim Ellison [EMAIL PROTECTED] wrote: (02/28/2006 21:10) Eric et. al. Joe, AB1DO mention this to me a couple of weeks back, but not until recently did I fully understand what he was talking about. Recently I started playing with Dream (DRM) and after a bit of trial and error, I was able to get it going with VAC 3.12. Now that I am actively using multiple digital mode software packages for different PowerSDR modes, I have experienced the cumbersome process of configuring VAC for multiple digital modes related to the mode buttons on the console. Not one to sit idly by and moan and groan to myself (boy do I love being able to converse directly with the development team) I have a program change request related to the VAC setup and digital modes within PowerSDR. Currently there are three mode buttons on the PowerSDR console that can evoke VAC when engaged; DigiL, DidigU and DRM. It would be WONDERFUL if you could set different VAC parameters for each of the buttons. Here is my justification. Most folk use DigiL with a RTTY program. And use another digital mode program, such as MixW when in DigiU mode. Last but not least using Dream with DRM. Each one of these programs has different soundcard settings which require different VAC settings. Since there is essentially a different digital mode program associated with each one of the different VAC enabled mode, I am constantly having to configure and reconfigure VAC when running primarily digital. That makes me have to remember the correct setup for each program and does not make changing from MixW to Dream to MMTTY as seamless as clicking the mode button on the console which it COULD be. If there was a setup tab (or even right clicking on the mode button (digiL, digiU DRM) that you could define different VAC parameters for each of the three VAC enabled modes, that would solve the conundrum of reconfiguring VAC every time you select a different mode.

Re: [Flexradio] filter descriptions
Bill, You can probably get a good mathematical explanation from Bob or Frank. I like to think that the window smooths out the edges of a set of data to eliminate high frequency false info caused by the sharp transitions. Practically, some of the window functions provide nice narrow spikes but tend to widen out with a big signal as you get lower in level. Others, like my personal favorite, the Blackman-Harris series, provide great dynamic range but tend to be a bit wider at the peak. The Hanning is nice for typical radio use since the signals are in the less than 90 dB level. Making measurements with large level signals over 100 dB level, the Blackman-Harris works better. The rectangular window is really no window at all. Try it on a big signal and you can see why some window is useful at most times. Tune to where you have large cw signals and switch the different filters. Some of the spreading that you see near the bottom of the signal is caused by the keying of the signal itself; it did not stop or start where it could get smoothed by the window function. You see the spreading intermittantly since it depends on whether or not the signal started or stopped in the tiome of the current data buffer.

To use this new version, and please do, leave the Setup-DSP-Keyer- NewKeyer check box checked and then use the new CWX button on the main menu to start up the new CWX functions. They are a part of the 'new keyer' and provide the extended memories and keyboard functions that the old keyer used to supply. There will be a new section added to the manual when it is released shortly but for now try it. There is a screen of notes that you can select that should get you going along with the tool tips.

Re: [Flexradio] Experts terminology and stuff
I agree with Eric also. Do not split this resource up. I also do not read some topics but certainly want to be aware of the discussions happening. Some of us caught some flak a few weeks ago discussing a 'mystery signal' in the middle of one of our ham bands. There may have been a dozen messages before it ended. We have such a great instrument in the sdr1000 for analysing signals, saving them, and sending them to others that can not hear them for some reaon. This should not be discouraged or split off into some other place just to satisfy those who happen to think they are not appropriate for this venue.

Re: [Flexradio] DATABASE OVERWRITE
Bill, If there is a database in the directory that you run from, it will use it else create a new one. If you run from the ide, that will be either ..\bin\debug or ..\bin\release depending on what you told it to do. If I have a bunch of stuff in a database that I want to keep safe, I'll just compy it elsewhere before I start a development cycle, just in case. I do that all the time keeping the old database. It sounds like you may be doing a clean as a part of the compile. Some of the clean functions will completely delete the \bin folder that contains the . mdb. This may be part of the deploy. I keep the deployment lines disabled since all I want to do is re-compile whatever I changed and then relink. It is all much faster that way as long as you are not interested in distributing it.

Re: [Flexradio] DIP OCXO for SDR
Gentlemen, The DDS does Direct Digital Synthesis hence the name. It does not divide back to anything but runs an phase accumulation engine at 200 MHz (or whatever the clock rate) that produces output values to the dac at that rate. No division is performed. Richard W5SXD John Ackermann N8UR [EMAIL PROTECTED] wrote: (01/04/2006 16:09) [EMAIL PROTECTED] wrote: First of all, any osc multiplied up widens its sidebands (phase noise) by the multiplication factor and the inverse is also true. The DDS does a 20X to 200MHz and a divide by 20 to get back to 10MHz. I guess it's academic at this point how much jitter is added by the DDS until someone measures it. You're only dividing back to 10MHz if that's the operating frequency. At higher operating frequencies, the division doesn't equal the multiplication (and of course, at lower ones it exceeds it). Measuring the DDS output lets us see the phase noise where it counts, taking into account both multiplication and division, rather than just at the fundamental frequency of the reference. Second, Rubidium standards are not intended to be used as local oscillators. They have terrible phase noise. They are intended to be used in timekeeping. It is their long term drift that excels, not short term phase noise. Agreed in general -- though there's a wide difference in performance between different types of Rb; some use FM modulation of the xtal, which results in horrible phase noise, while others, like the 5065A, don't. My post wasn't suggesting that you use an Rb as the primary reference. However, the DDS output when driven by 10MHz shows the effect of the multiplication, which is all I was trying to do. My web page also has a plot of the HP 5065A phase noise at 10MHz, so you can see the difference in noise between the raw and multiplied frequencies. John http://www.febo.com/geekworks/sdr1k/sdr1k_phase/index.html has screenshots that show the phase noise at the output of the DDS for the standard 200MHz oscillator, and an HP Rubidium frequency standard at 10MHz multiplied by 20 in the DDS. You can clearly see the phase-noise hit caused by the multiplication.

[Flexradio] remote sdr-1000
Several folks have asked me about remote operations for an sdr1000. http://flex-radio.com/download_files/PowerSDR/Docs/SDR_Remote.pdf outlines some basics. My system has just started operation this week and is described here. I have a 100 w sdr1000 operating in remote service. I use Skype for the audio and LogMeIn for the video and controls. It is all free software and works very well. The system described in the link above went to a lot more effort than I did to handle the audio. I simply use a second sound card for Skype and plug directly from its line and mic ports into the speaker and mic ports of the Delta-44. I get excellent audio reports with no transformers or other conditioning. It may not work as well at higher power but 100 w is no problem. I am using an old crashcraft r6000 vertical. The response time is very good with the panadaptor updating at 4-8 Hz when set at 15. I use a Heil Pro Set headphone/mic for the audio interface. CW ops are only using the memory/keyboard but I'm working on improving that. I use an eight outlet ethernet power controller http://www.digital-loggers.com/EPC.html to allow me to turn the computer, cable modem, and sdr1000 on and off. It also lets me switch antenna relays and room lights for the webcam from remote. The webcam is for watching the eme dish outside the window. The remote computer has a cable modem followed by a router/ switch so the power controller is a seperate internet entity and can control the computer. It also provide watchdog capability to get restarted after a crash. Richard W5SXD

The objective, in addition to muting the audio is to have the RX up and running immediately upon release of the mute. It should, in addition to being a single hardware closure, work thru the CAT. Richard W5SXD Eric Wachsmann - FlexRadio [EMAIL PROTECTED] wrote: (12/14/2005 10:50) Well, again, I'm confused by your description because we already have a Mute feature that kills the audio without affecting the AGC. If you're saying that you need a way to do this via an external relay, then that is something that could be arranged in the software. You could hook one of the X2 inputs so that it asserts the Mute when it detects that it has gone high.

I have been wanting to use it with a couple of other transmitters and haven't found a way to mute the receiver during the transmit period. I guess anything that would lift the audio would work but it would not be a very elegant way to do it. Doing it that way would require the AGC to recover etc. I have noticed the software mute button on Power SDR but that would be cumbersome.

Re: [Flexradio] Xylo Update
Phil, Are you saying that you will modify any zero sample by one count to guarantee uniqueness of the sync? Also, it would seem that you would not want to reduce bandwidth by 1/3 to sync every stereo sample. I sync only once every 500 channels in a larger system in the same manner with no confusion. Richard W5SXD [EMAIL PROTECTED] wrote: (12/01/2005 22:48) Hi Phil, I used 48kbps and 16 bit samples to keep things simple for the first test. I also just used the left audio channel and the blocking version of the PortAudio code - again a simple first test. I was looking at using one of the 2^n A/D states as a flag to indicate the next data word is say left. Having looked at the output of the Wolfson chip even with the input shorted you rarely see 0x as data. With a bit of band noise we will be well above the zero threshold. So I am going to start with 0xLeft_dataRight_data0xLeft_dataRight_data etc Since data delivery using Bulk mode under USB2 is guaranteed I think that should be sufficient and the loss in dynamic range acceptable in practice. Bill suggested that we may not need to send the 0x sync character as often as shown above given the reliability of the USB2 connection and I will try reducing its frequency once the above is working. I was also thinking of not bothering with testing under PortAudio but going straight to a PWM D/A converter in the FPGA for the Rx audio. That way I achieve my goal of removing the sound card and all the Windows drivers - reading and writing to the Wolfson and D/A's will take but a few lines of code then. Rather than a second A/D converter chip for the mic I was also going to look at using a PWM ramp feeding one input of a comparator and the mic signal the other. It may have no advantage over a single chip A/D, given the low cost of these nowadays, but a fun exercise anyway. I only wish that I had time years ago to lean to use FPGAs, they sure open a whole world of possibilities! 73s Phil VK6APH Quoting Philip Covington [EMAIL PROTECTED]: Hi Phil, Good deal, sounds great!

Re: [Flexradio] FW: Impulse Wave file
In our military system tests we acquire 10-20 impulses and sum them in the frequency domain. If the ripple is actually in the system then it will stay in. This was what the generals all wanted. In our seismic stuff, where the geophysicists seem to think it is needed to find oil, we require the 1 dB flatness in the frequency domain plateau of a single impulse. Another possible problem is that the data before and after the impulse must be un-modified by another impulse coming along for at least the time to get thru the last fir filter stage in the sigma- delta converters. This takes 29 samples in our seismic converters. At that point the response should have dropped to zero, of course, but any analog stuff may still be banging about.

Re: [Flexradio] FW: Impulse Wave file
Another thing about the impulse generator in my system at work. The
impulse starts 1/3 of the way between sample intervals, and lasts 1/3
sample interval. This guarantees that all of the energy falls
between two sampling points. The sample rate is typically 500 or
1000 Hz. However , since the impulse is routed thru the front end low
-cuts and preamps which have a certain amount of delay, it is unclear
to me what the importance of the centering is. It does of course
produce results that are reproducable from one day to the next and
may be the result of a bit of specsmanship :)
Are you planning on having this generator complete to the point of
producing a short .wav file for outside analysis?

Re: [Flexradio] 1 kHz snap to
Yes. Several others have suggested this also. When the panadaptor gets out to 100 kHz someday, it will not be as easy to click tune ssb signals since they will not be as wide. It obviously would not be used for cw or even when not in the panadaptor mode but since the lower edge of a ssb signal is almost always on a 1 kHz boundry, it make sense there. The mouse wheel, set at 1 kHz, works very nicely. This would not replace that, just augment it when enabled.

That may be. I saw the same error in the 10m bandstack using imported database from 1.4.5.4. I went back and started from scratch not importing the old database and the error went away. It may have something to do with the addition of the NCDXF beacon identifiers.

Re: [Flexradio] USB Sound Card
The creative mp3+ and extigy both work fine on my laptop. I have not yet tried the firebox. They do eat up a bunch of extra cpu cycles and performance is right on the edge with a 1000 MHz P4 laptop. There are several others. Which one do you have? Richard W5SXD Robert [EMAIL PROTECTED] wrote: (11/12/2005 12:50) Well I just ordered the SDR-1000 yesterday and patiently awaiting delivery.

[Flexradio] 1 kHz snap to
It would be nice to be able to instruct the cursor to only stop at even 1 kHz positions whilst moving around the panadaptor display. An amazingly large number of ssb qso's are one 1 kHz boundries so tuning with the cursor would be a nice 'snap to' operation. Richard W5SXD

Re: [Flexradio] CAT CONTROL CHECK BOX P3 P4
And for free you can have the classic hp41 running on your windoze desktop and/or your pocketpc. The folks actually use the roms from the real hp41 and wrote a processor to emulate the machine. It therefore works EXACTLY like the original. Great stuff. See them both at http://www.hp41.org Having used HP machines since that day in 1972 when my slide rule went into the desk drawer replaced by the hp-35, I have always carried an HP machine in my shirt pocket where the pocket protecter had been before that. I have found a machine that I like a little better than the hp41 because of it's ability to do math in lots of different number systems including time. It is only $11.85 and has a version for both windoze and pocketpc. See it at http://www.calculator.org . Highly recommended. Enjoy!

I have found this on-screen calculator to be very handy. It is on my desktop computer as well as my notebook. It is shareware and very inexpensive. You should check out http://www.dreamcalc.com/ It does lots of scientific calculations, plus financial, plus it does a lot of GRAPHING, as well as having a lot of useful scientific constants available. Lots of statistical functions, Base-N and logic functions, and over 630 constants and 80 conversion functions. For a list of features try http://www.dreamcalc.com/calculator_features.htm It works great on complex numbers and does polar plots. I am working on the author to add Smith Chart calculations. Here are some graphing screen shots. http://www.dreamcalc.com/graphing_screenshots.htm I am just a very satisfied customer who got to know the author after making some suggestions. He put in 8,000 hours on the project. It not only can use RPN, but also modern algebraic or classic algebraic entry. The standard edition is only $19.99. And the professional edition is $29.99. All features work in the shareware download and there is no time limit. If you don't pay for the key it will occasionally remind you. It is probably the best value for shareware that I have ever found. 73 John W0UN ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz

Re: [Flexradio] Wish List - Memory Save/Recall Enhanced
John, It would be nice to have all the parameters saved. The problem is that on restoration you may only want the frequencies and some off the wall parameter that gets unknowingly restored on a recall will send you scurrying to find what is wrong and, you will have lost the previous setting. Some way to recall just frequency would be nice. In addition, the menu should close when an entry is selected (perhaps optionally). The entire radio state should be saved prior to any change on a pushdown rollable stack so that if you select some new setting that is wrong, you can pop back to te previous setting and even further. PUSH would toss the oldest setting if it differed from the top of the stack. PUSH would be automatic on frequency changes but would have a button also. POP would roll the stack thru 4-6 entries. Richard W5SXD -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Saturday, October 22, 2005 2:50 PM To: FlexRadio@flex-radio.biz Subject: [Flexradio] Wish List - Memory Save/Recall Enhanced I would like to see the memory save/recall include 'all' SDR1000 settings- console controls and all the setup contents. This will allow a lot more flexibility. Example 1: For DX the user wants to use a beverage antenna for rx and a dipole for tx. Using a relay and 'Ext. Ctrl' this is easy to setup and use. On the other hand, switching back to local ragchew mode using just the dipole requires opening up the setup/ext cntrl tab and making changes to the pins. A better way is to save two setups with and without the different bits set. To differentiate the two, the user simply uses the comment field. Also the 'DX' memory would contain all the other parms, such as compression, number of taps for NR, etc. To easily recognize the setup you could set different colors for each setup before you save it. Example 2: You use an external linear amp. Save one memory with 'Enable X2 TR Sequencing' checked to use the amp and another unchecked to disable it. I think the benefit to the user is 'FlexAbility'. :) For the software guys, you don't need to find room for another console button to perform a desired function. Just my $0.02. 73 John ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz
[Flexradio] 1.4.5 keyer

What is a 'N1MM'? I am trying to hook in to key the radio from the com port which happens to be a serial/usb type. No joy iambic or not. Works fine when going in thru the lpt.
