Re: [Flexradio] Audio out though computer speakers
Yes, it is doable, but as a permanent operating solution, simpler is better by minimizing the "layers" you have to put in and manage as a consequence of doing so. The nice thing about SDRs is there are many ways to skin the cat. :-) -Tim -Original Message- From: Ray - K9DUR [mailto:k9...@rnacs.com] Sent: Thursday, March 25, 2010 12:17 AM To: Tim Ellison; 'Drax Felton'; flexradio@flex-radio.biz Subject: RE: [Flexradio] Audio out though computer speakers Tim, To avoid having to use external speakers at Hamfest demos, I normally connect the "PWR SPKR OUT" on the Flex to the "Line In" on the laptop's built-in soundcard.

Re: [Flexradio] Audio out though computer speakers
That would require the interaction of a sound card in the PC which is a separate hardware device with PowerSDR. PowerSDR would have to control the gain of the sound card directly as you should have a fixed gain source (PowerSDR) and vary the volume of the sound card's AF PA which is the last PA in the audio chain for best S/N. It is a bit of a complicated scenario to deal with by having to support a multitude of sound cards. You can actually do this with the VAC configuration in PowerSDR (not actually using VAC) if you like, but you have to manually match and control the output gain from the external soundcard to the speakers. -Tim -Original Message- From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of Drax Felton Sent: Wednesday, March 24, 2010 11:12 PM To: flexradio@flex-radio.biz Subject: [Flexradio] Audio out though computer speakers New user question: If the Flex 5000 is using the computer to do all of its DSP work, why then is the audio fed back into the Flex box where I have to hook up powered speakers to the back of it?

Re: [Flexradio] Which PowerSDR version to use?
Drax Welcome to the club! As a best practice, always install the current versions of software, firmware and drivers listed on the home page http://www.flex-radio.com/. This is the stable and released software that is officially supported by FlexRadio. There are detailed instrctions on how to install/upgrade these components on located in the Knowledge Base. PowerSDR 2.0 is not released software - yet. It is alpha software that is under development and is not recommended for new users or those who desire a stable, reliable operating environment. Alpha software is for testing new and potentially buggy code only and there are a lot of caveats and precautions one must understand and accept before using it. One of those is that there is no official support for if from FlexRadio other than what the developers provide when testing specific features. Most of the support is user provided on the FlexEdge reflector. For more information about the FlexEdge Reflector, please see the following web page: http://www.flex-radio.com/Support.aspx?topic=Reflector_Description To sign up for the FlexEdge Reflector, use the FlexEdge Reflector User Management web page (http://mail.flex-radio.biz/mailman/listinfo/flexedge_flex-radio.biz) and go to the Subscribing to FlexEdge section. -Tim -Original Message- From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of Drax Felton Sent: Wednesday, March 24, 2010 10:27 PM To: flexradio@flex-radio.biz Subject: [Flexradio] Which PowerSDR version to use?

[Flexradio] Low Output
Hi All, I have the following: Flex-3000 FlexDriver: 3.5.0.7171 Firmware: 1.2.5.6 PowerSDR: 1.18.5 Operating System: Win 7 64 Bit. Last night the FlexDriver dropped. I shut down PowerSDR. I then powered off the Flex-3000. When returning to air. The FWD PWR indicated about 10 to 15 Watts on SSB With the Drive setting at 100. I switched to the dummy load and had the same problem. I reset the database and the same result. Frequency is 7.268.5KHz. Mic Gain Verified at 15 CODR at 5. Mic is a Yaesu MH-31. Tested all Bands Same Results. I decided to use tune to see the results, as previously I have been able to tune into the dummy load at 100 watts. Max power indicated out was 19 Watts. Cross checked with a external Watt Meter verifies output readings. As I still had PowerSDR 1.18.3 on the computer, I tried it with the same results. Database reset did not make any difference. I think there may be an issue.

Re: [Flexradio] V/U unit
We should complete our testing of the redesigned VU module by the end of this week. At that point we will release beta to production and should have a better idea of the schedule. We will plan to communicate to everyone as soon as we have a schedule that we feel is reasonably accurate. We are finding that materials availability has become extremely unpredictable as the economy is picking up. This unfortunately adds uncertainty to our plans but we are working those issues as they arise. 73, Gerald Gerald Youngblood, K5SDR President and CEO FlexRadio Systems(TM) 13091 Pond Springs Road, #250 Austin, TX 78729 Phone: 512-535-4713 Ext. 202 Email: ger...@flex-radio.com Web: www.flex-radio.com Tune In Excitement (TM) PowerSDR(TM) is a trademark of FlexRadio Systems On Wed, Mar 24, 2010 at 8:21 PM, Ed White WA3BZT wrote: > Hi Gang: > When do you expect to start delivering/ reworking the 60 W units? > Ed > WA3BZT > > ___ > 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/ > ___ 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/

Re: [Flexradio] Getting started with transverters
Matt, I'm using transverters with my 3000 through Down East Microwave's AOS-28 interface box, which attenuates up to 25 watts down 100mW (default, factory adjustable). It takes care of all the RF switching so that the receive is not attenuated (eliminates the need for external relays). All in all a very nice box for the relatively low price. The other option is to buy transverters that have the RF switching and attenuators built in, like the Elecraft ones Tim linked. Personally if you are going to buy new I'd wait for the new line of DEMI transverters. 73s, K1FSY On Wed, Mar 24, 2010 at 3:56 PM, Tim Ellison wrote: > I am not expert by any means in this area, but I can start you off with > some info. > > A transverter usually a very low level RF input on one frequency and > outputs RF on a higher frequency and usually of a higher wattage. > > For the FLEX-3000, the output frequencies (called the IF) will probably be > 10 and 6m and the resulting RF output is 144, 222, 433 MHz or higher. > > One thing you have to be careful of is the RF drive from the FLEX-3000. > Transverters can require milliwatts to several watts of RF drive max.

Re: [Flexradio] Getting started with transverters
I am not expert by any means in this area, but I can start you off with some info. A transverter usually a very low level RF input on one frequency and outputs RF on a higher frequency and usually of a higher wattage. For the FLEX-3000, the output frequencies (called the IF) will probably be 10 and 6m and the resulting RF output is 144, 222, 433 MHz or higher. One thing you have to be careful of is the RF drive from the FLEX-3000. Transverters can require milliwatts to several watts of RF drive max. The FLEX-3000 does not have a dedicated transverter interface that limits the RF output to very low levels like the FLEX-5000, so you may need an attenuator on the RF output of the F3K to limit the drive. Just about any transverter can be made to work with the FLEX-3000 Popular ones are from Elecraft http://www.elecraft.com/XV/XV.htm DownEast Microwave http://www.downeastmicrowave.com/ SSB Electronics http://www.ssbusa.com/transys.html -Tim -Original Message- From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of Matt Steven AI1P Sent: Wednesday, March 24, 2010 3:37 PM To: flexradio@flex-radio.biz Subject: [Flexradio] Getting started with transverters Hi, I haven't found anything about transverters for VHF/UHF in the Flex KB other than a few for what looks like a kit for the 1000.
