[Flexradio] Digital modes
Eric Now that the VAC is implemented, how long will it be before the digital modes are enabled? I think Bob mentioned the code has been ready. Recommend when you do, that when clicking on RTTY or PSK (one for SSTV too?) that the VAC is automatically enabled. When click any other mode it should automatically be disabled.

Re: [Flexradio] Digital modes
I cannot see how this would work without considerably more effort than anticipated for version 1.0 of this. Some people would want to use external hardware. Some people want to use programs to decode CW. Some people want to use external audio programs on SSB for both the microphone and the output. Until all get a look and Eric figures out how to balance all of these needs, I would not expect this to be implemented in this completely controllable form.

[Flexradio] Final reminder about enclosure and RFE upgrades - expires November 15th
Dear FlexRadio customers, This is a final reminder that November 15th is the deadline for ordering enclosure or RFE upgrades. A copy of the announcement posted on October 25th is provided below for your reference. 73, Gerald K5SDR Posted: Tue Oct 25, 2005 4:06 pm Post subject: One time RFE board and Enclosure upgrade opportunity Dear FlexRadio Customers, Many of you originally purchased the SDR-1000 three board set without the RFE board and/or the enclosure. For some time we offered these components as optional upgrades but more recently we have stopped carrying them as standard items. This is a result of our now selling only complete radios and the need to effectively manage our inventory. We have received a number of requests to purchase these upgrades so we are making a ONE TIME FINAL UPGRADE OFFER GOOD THROUGH NOVEMBER 15, 2005. During this period you can purchase the RFE upgrade (SDR-RFE) for $225.00 and the fully assembled enclosure (SDR-ENC) for $250.00 plus shipping and handling. THIS ORDER IS NON-CANCELABLE. PLEASE ALLOW UP TO 8 WEEKS FOR DELIVERY. The online shopping cart on our website is the preferred method of purchase but telephone and fax orders will be accepted. Please note that the RFE and enclosure include all of the latest modifications and upgrades. Thanks and 73, Gerald Youngblood K5SDR FlexRadio Systems Phone: 512-250-8595 Fax: 512-233-5143_FlexRadio Systems The radio that just keeps getting better!

If this is correct, then I assume that I canuse this sound card for other applications including the Teamspeak Forum.It seems a shame to have a 3 GHz machine sitting there only using between 7 and 12 %of its processing power (for the SDR and surfing) and running Teamspeakfrom a laptop.

[Flexradio] Very Impressed!
Well, I have had a couple days to play with the SDR-1000. Made contacts on CW, PSK31, RTTY and SSB. I am very pleased with the way it works. I had rather expected that I would end up spending most of my time figuring out how to solve glitches in software, but even running 1.4.5 Beta 4, I have had no real troubles. My first PSK31 QSO was with TU5JM in Ivory Coast. Not bad for 10 watts. Compliments to the Flexradio gang. I am looking forward to the next CW contest, and giving this a go with N1MM and Winkey (which seems to to working great). Now all I need is the magic word to get it to work on MARS, and I can try checking into the MARS net with it. -- _____ / \ / \ / \ / \ / \ John L.

Re: [Flexradio] FlexSDR Software components
Cecil, The majority of the developers working on the PowerSDR source use the MSVC .NET compilers/IDE. The GUI is written in C# and the DSP is in C with several supporting libraries written in C as well (Portaudio, PortTalk, FFTW2, pthread). Having said all of that, it seems that it is not too terrible (based on N8VB's experience) to port the source for use with a free compiler like SharpDevelop. We don't currently have a block diagram of how things work because we are in the midst of changing the architecture to something much more appealing. As soon as things have settled out on our new architecture, you can expect that it will be much better documented than the current version.

Re: [Flexradio] Just wondering about the NR
Tim (really directed more generally), The ANF/NR settings are highly subject to band conditions. What works for us here in the lab doesn't always work for N4HY in NJ. We have selected values that seem to work fairly well across the bands _for us_. When the ANF is working properly, I have seen it notch as many as 4 carriers inside the passband with excellent attenuation while coping an SSB signal. The NR seems to be pretty hard to describe other than the fact that if you get the settings right, you will be able to copy stations down near the noise that were just barely audible before. N4HY might be able to describe these functions a bit better. The Operating Manual does an excellent job of describing the controls that manipulate the NR/ANF.

Re: [Flexradio] Just wondering about the NR
Tim, My more general response was not directed at you (as it indicated), but at the reflector in general. Because these sorts of questions get archived, many times similar questions come up. I hope you understand that we ENCOURAGE these types of questions and interaction on the reflector. It sounds like you have a good handle on where to go for resources when you run into a problem, but many people searching the archives do not. This was the reason for my mentioning the manual in my previous response. (throw Teamspeak in there somewhere too) ;) I probably did not adequately respond to your original question given my more general response (again, more for the sake of the archive than directed at you). I will say that we have fixed an AF bug that was causing lower audio just today. This will be in the next release (v1.4.5 Preview 6). However, I'm not sure that this is typical operation for the NR (much lower volume). It sounds to me like the values might be too aggressive for your particular situation. N4HY aka the expert would likely be the best person to comment here.

Thanks for the response. I haven't bought the notebook yet so I can't test it. The processor is a Intel pentium 4 mobile 3.06ghz with hyperthreading. Its number is 532.

Re: [Flexradio] VAC and Second sound card
Serge: If you are using the CAT or COM port PTT for CW, it is likely that the MixW setting is asserting PTT because you have the MixW setting in TRCVR control port in options set to ALWAYS ON. Check the CAT control port settings MixW and in PowerSDR make sure that Setup-DSP-Keyer has the correct settings in the Secondary Port or Primary Port. If you are using a virtual com port and Secondary port, the PTT and CW settings MUST match those in MixW.

Re: [Flexradio] Pentium M
To answer your question, I assume you are going to run some flavor of Windows on your new laptop. Laptop hard drives are slow compared to their desktop counterparts. In order to reduce the possibility of extensively using the swap file, get the extra RAM. It isn't that expensive in the grand scheme of things and you will always find a way to consume it. With several applications running, you will probably only use 256 - 384 MB during normal operation unless you are loading a lot of large database tables into RAM . -Tim --- Tim Ellison ( [EMAIL PROTECTED] ) Integrated Technical Services ( http://www.itsco.com ) -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Lee A Crocker Sent: Monday, November 14, 2005 8:32 PM To: FlexRadio@flex-radio.biz Subject: [Flexradio] Pentium M Thanks for the response.

[Flexradio] A simple fan noise abatement modification
One of the first and only negative thing I noticed about my SDR1K on its initial setup this weekend was how much fan noise there was with it sitting on my desk. Since I knew that the fan noise was being picked up by the microphone and I really didn't want to put the unit under the table (can't show it off when it is out of sight), I decided to do a little research to see if there was something I could do to reduce the fan noise and share the process with the group. My first though was just get a quieter fan. I first removed the fan from the front panel so I could get the part number and retrieve the data sheet from the web. What I discovered was that the specifications of the fan used by Gerald crew in the SDR1K are the upper range compared to other 80mm X 15mm fans. No skimping here - Thanks Gerald! As per the data sheet, the fan provides 22 CFM airflow @ 2000 RPMs generating 23 dBA of noise. After an extensive search of the Internet I could not find a fan with better specifications. So, the quick fix was out of the question (isn't it always) It didn't take too much effort to figure out that a large component of the fan noise was the volume differential between the fan intake vent and the volume of air being drawn in by the fan. Just by looking at the air intake holes located within the area of the fan casing, it was fairly evident that approximately 50% of the total area was blocked. A simple test of this theory was to fire up the SDR1K while holding the fan next to the chassis vent holes and moving it away by 10 mm. The fan noise decreased at least 80%. Now I had two options. One was to use small stand offs on the fan mounting screws to decrease the pressure differential or modify the chassis to allow more air through the fan intake opening. Not wanting to disturb the laminar air flow by creating an inefficient open loop, I opted for the later option. The mod: I disconnected the power switch, mic connector and fan and then removed the front panel from the chassis. Using the outside of the existing air holes as a guide, I scribed an octagon on the front panel by creating a tangent across three successive vent holes creating eight sides. Using my trusty Dremel tool (a most excellent toy) and a metal cutting wheel, I cut out the octagon traced on the front panel. You want to make sure you don't do any metal work with the electronics in close proximity since the cutting process creates very fine metal dust that gets everywhere.I smoothed up the rough edges with a grinding wheel and then used a little flat black paint to cover the exposed metal edges. I replaced the front panel back into the chassis along with the mic connector and power switch. When I reinstalled the fan and the bezel, I used some small flat rubber washers in between the fan and front panel to dampen the harmonic vibrations the fan induces when the fan is running. I replaced the snap-on dust filter and fired up the SDR1K. The results were instantaneous and absolutely amazing. I probably reduced the fan noise by 100% easily. The fan in the Astron SS-30M is louder than the SDR1K and it is a relatively quite fan. One added benefit of the modification was the increased volume of air flowing over the PA heat sink increased its thermal dissipation efficiency. Subjectively, I could feel more air flowing out the exhaust holes and the temperature of the exhaust gas was somewhat less than it was before the modification. The whole process took less than 30 minutes to complete (minus the time to go the Lowes to get some rubber washers). I now wish that I had a way to measure airflow and to take some before and after temperature readings of the exhaust gas along with some pictures documenting the process so I could provide a more complete assessment of the benefits resulting from the modification. All I know is the SDR1K is much, much quieter, the PA runs cooler and since the fan experiencing less mechanical and thermal stress, it should last longer. I have a large (500 MB) close up jpg of the finished product without the dust filter if anyone would like to see it. Just send me an e-mail directly and I'll forward it on. 73 de W4TME -Tim --- Tim Ellison mailto:[EMAIL PROTECTED] Integrated Technical Services http://www.itsco.com/ Apex, NC USA 919.674.0044 Ext. 25 / 919.674.0045 (FAX) 919.215.6375 - cell PGP public key available at all public KeyServers
