Re: [Flexradio] Re. [Flex Radio] Laptop CPU percentage usage -potential problems.
As to the question of laptops, the cited machine is probably OK. I have an aging Celeron laptop at 1.5 GHz which works marginally well for SDR use with the Extigy soundcard. I did not buy it for SDR useage either, but it manages to do the job when I ask it to. Just. There are occassional glitches -- it is just about all my lappy can handle. So, I'd say that the cited machine will probably turn out to be OK. There's probably enough GHz in it. More than enough, in fact. The main issue is likely to be whether there's enough L1/L2 cache to run totally glitch free. It will run better than mine. If you're springing for an SDR to start with, I'd give serious thought to a desktop machine with the Delta 44 card in it. There's a lot of excitement about the external sound cards that give wider bandwidth just now. But for HF usage, that's not so important IMHO, and, in any case, the easiest way to make the laptop work better is to use the more normal bandwidth as the older cards do. Even if the sound card is capable of more. Since the SDR is a great base station rig, a 300 dollar, used, Pentium IV 2.4 GHz XP machine as an accompanyment isn't a bad choice. That combination is glitch-free for me and has garnered me about 190 DXCC countries. The Delta 44 is about 200 dollars more, with cables.

Re: [Flexradio] Receive Attenuation Glitch
With at least the 1.8.0 level, there's a little glitch I've noticed that might also be related to another recent thread. Sometimes, when I've just turned the rig on, I find the receive is attenuated an extra 20 dB or so somehow. It actually looks, visually, like a good deal, because the noise floor is down 20db. To clear it, all I have to do is transmit, however briefly. The noise floor comes right back up to normal after that.

Re: [Flexradio] Receive Attenuation Glitch
Hi Larry, I've seen this too. I'd always assumed it was something in my external auto-antenna tuner that was making a poor contact and that, because I was passing current through the connection when I transmitted, that made it became better. It's possible too, though, that it might be something in the SDR radio, such as a relay making a poor contact. (In my case, I don't believe it's a software glitch.) Next time it happens I'll try to remember to turn on another receiver and check if it's also attenuated through my tuner. If not, then that would point to the SDR (or my antenna switch), rather than the tuner. - Jeff, K6JCA -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Larry Loen Sent: Sunday, March 04, 2007 3:21 AM To: FlexRadio reflector Subject: Re: [Flexradio] Receive Attenuation Glitch With at least the 1.8.0 level, there's a little glitch I've noticed that might also be related to another recent thread.

[Flexradio] Panoramic vertical scale
I'm sure this has been answered many times, but the it seems to have fallen out of my brain. According to the Manual, the Received Signal Meter reads the actual RMS power within the filter passband. This means it should scale with the width of the filter and it sure seems to do so. I can't find any similar definition for the vertical scale of the Panoramic Display. What does that reading mean? If it were the power in the minimal FFT bin, I would expect it to scale with the DSP Buffer Size, i.e.., fewer FFT point = wider bin = more signal. Maybe I'm missing it, but it doesn't appear to scale that way. Is the vertical scale already divided out to be RMS power/Hz? Thanks Chris - AE6VK -- next part -- An HTML attachment was scrubbed...

Re: [Flexradio] Preamp issue - Results
I get about -130dBm when I use this method. Is this what was is expected??? Mark NU6X This is just not possible with the way we do calibration. Something else is amiss. After calibration against a known source, BOTH of your radios should read -90 dBm if you present -90 dBm at the antenna terminals. That is because the calibration process removes all of the system differences at the calibration frequency. NOW, you can have a higher NOISE FLOOR than Joe. That is entirely possible. Calibrate your radio so that BOTH OF YOU read the exact same meter readings given the same source (and the peak on the display shows up at the same level on the display). Set your filter to 500 Hz. Read the METER in Signal Avg setting. TURN THE TONE OFF. The meter reading will be of the average cumulative noise power in the 500 Hz filter. THIS IS the definition of MDS as measured in the ARRL labs. It is mathematically equivalent to what they do.

Re: [Flexradio] Receive Attenuation Glitch
Here is an explanation of what might be going on. If when you experience the condition where the noise floor is 20 dB lower than expected and you are NOT hearing any signals, something is probably amiss with the DDS. This phenomenon you are experiencing is when the DDS gets stupid, meaning that the software can not communicate or control the DDS. This isn't a problem with the DDS but is more of a symptom than the actual root problem. As soon as you cycle the rig PowerSDR re-established communication with the DDS and all is usually well again. One thing you can check is the control cable (parallel or USB). Unless you use good high quality cables (full shields, soldered connection and ferrite beads), both will be susceptible to RF. Keep the cable as short as possible and do not route then near RF sources. You need to make sure that the devices (parallel or USB) have the specified amount of voltage. A lot of laptop, mobo, and cheap PCI I/O cards may skimp in this area. Grounding is another concern for RFI abatement. RF grounds are usually only needed with unbalanced antennas, but even balanced antennas are not perfectly balanced. Have a single point ground (either AC safety or RF) is usually not a bad idea. Make sure you bond all of your grounds together at one spot, usually where the AC service comes into your house so everything is as near to the same potential as possible. -Tim, W4TME -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Larry Loen Sent: Sunday, March 04, 2007 2:24 PM To: Frank Mayer Cc: FlexRadio reflector Subject: Re: [Flexradio] Receive Attenuation Glitch Frank Mayer wrote: Larry, I have noticed the same thing here on and off.

Re: [Flexradio] spam: Tune question
Tom, When working split (DX - 40) I normally only tune the transmit once, then tweak the receive throughout the QSO. Having the transmit side be the default for tuning could make me more prone to messing up. I excel at messing up, so anything the help avoid that is good. I do use the AB feature to do the first tune of the transmit frequency. This allows me to verify that the frequency is available (not in split) on my end prior working the split. Once the frequency is know clear, I'll swap the A and B VFO and then hit split. Now my A is receive (default tuning) and by B is transmitting on what should be a clear frequency. 73, Dan Tom Thompson wrote: John, I noticed that when working split that the TUNE function uses the VFO A frequency.

Re: [Flexradio] UCB schematic and header question
Ross, I haven't done that specific thing myself, but have a look at the XVTR Setup Window that you get from the XVTRs button on the Main Menu Bar. The idea seems to be that you use the VHF+ button on the Band Panel, which switches the buttons from HF bands to just numbers. Then you set up what you want the buttons to mean on VHF via the XVTRs Window. In particular, if you enable Band Button 0, for example, then you can select the UCB Address [= Relay Number. Note that the Pins on the ExtCtl Panel represent the _bits_ of the UCB Address with Pins 1-4 giving you Relays 0-15.] You can also set up other useful stuff like the real frequency covered by the XVTR. There is a little more detail in the 1.8.0 SDR-1000 Manual, Chapter 9 Operating Forms. I'm not completely sure how you are trying to set things up, but it sounds like you have only two choices - select 2m or select 70cm. That sounds like a single button/relay will do using the normally open connection. E.g., enable Button 0 for 70cm and select UCB Address 0. Then, when you select Button 0, the UCB relay will close, switching your control relay to the 70cm position. If you select any other button - enable another one for 2m and some other Address - the relay will release and the control relay will switch to 2m. That's probably garbled some but I hope you get the idea. Keep me posted.

My apologies if it coms up twice. I have built up the UCB , but I have a couple of questions. (a) the schematic on the K3TUF website does not show U13, U14, U15 etc is there an updated schematic anywhere? (b) at the bottom of the board is a 10pin header, this does not appear to be in the schematic either, are these pins supposed to be jumpered? if so is it across the board? (c) what is INP6 (as shown on the schematic) and where does it come from? Assistance please. Thanks Ross ZL1WN -- next part -- An HTML attachment was scrubbed...

[Flexradio] ShuttlePro
All, I haven't used the ShuttlePro for a week or so (it worked when I demo'd the rig two weeks ago, but I haven't used it since.) It appears to have stopped talking to PowerSDR. Anyone else notice it disappear or have any ideas where to look? ShuttlePro device configuration works fine, the buttons light up, etc. I've pointed it at the correct PowerSDR.exe (I'm using Alpha v1.9.0 SVN: 917.) Is there a setting in the PowerSDR setup that I might have turned off that would disable the ShuttlePro? Mark -- next part -- An HTML attachment was scrubbed...

Re: [Flexradio] UCB schematic and header question
Ross, Expanding a little on Chris's reply The PowerSDR software will allow you to operate the relays on the UCB board via the X2 connector on the SDR-1K. And as Chris pointed out, the XVTR button on the main menu bar will lead you to the main transverter screen where you can specify which button you want to use for which band, what you want the button to say, what the frequency offset is for each transverter, and what the frequency tuning range is for each transverter. You will want to define separate buttons for each band. Now, in addition to all that, you will need a coaxial relay that will switch the RF from the SDR to the appropriate transverter. See Mike King's excellent article on his web site at http://km0t.com/ . With only two bands to contend with, you could use a simple single pole, two position coax relay similar to what is normally used as a T/R relay. In one position, the RF output of the SDR would be connected to your 2M xverter, and in the other position, the RF output of the SDR would be connected to your 70cM xverter. Use one set of contacts on one of the relays on the UCB to control the switching of the coax relay. You will also need to get the PTT line to both xverters. In some cases, you may find it useful to key both xverters at the same time so the RF output from one doesn't damage the RX front end of the other one. The PowerSDR software is incredibly slick for controlling multiple xverters. I am currently controlling 8 separate xverters with mine, and it works like a champ. I'm working on an article that describes the whole thing, and hope to be able to submit it to the knowledge base in the near future. Hope this helps.

Day Sent: Sunday, March 04, 2007 7:39 PM To: Ross Cc: FlexRadio@flex-radio.biz Subject: Re: [Flexradio] UCB schematic and header question Ross, I haven't done that specific thing myself, but have a look at the XVTR Setup Window that you get from the XVTRs button on the Main Menu Bar. The idea seems to be that you use the VHF+ button on the Band Panel, which switches the buttons from HF bands to just numbers. Then you set up what you want the buttons to mean on VHF via the XVTRs Window. In particular, if you enable Band Button 0, for example, then you can select the UCB Address [= Relay Number. Note that the Pins on the ExtCtl Panel represent the _bits_ of the UCB Address with Pins 1-4 giving you Relays 0-15.] You can also set up other useful stuff like the real frequency covered by the XVTR. There is a little more detail in the 1.8.0 SDR-1000 Manual, Chapter 9 Operating Forms. I'm not completely sure how you are trying to set things up, but it sounds like you have only two choices - select 2m or select 70cm. That sounds like a single button/relay will do using the normally open connection. E.g., enable Button 0 for 70cm and select UCB Address 0. Then, when you select Button 0, the UCB relay will close, switching your control relay to the 70cm position. If you select any other button - enable another one for 2m and some other Address - the relay will release and the control relay will switch to 2m. That's probably garbled some but I hope you get the idea. Keep me posted.

I have my SDR1000 1 watt rig, set up to drive a transverter on 2m an 70cm. by enabling 1 and 2 in the XVTR option. I have relays feeding the 2 and 70 transverters, I wish to use the UCB to control the relay that selects either the 2 or 70cm relays. So far I haven't worked out how to do it. My idea is that when I select say 1 (which is 144mhz) then the controlling relay will switch the SDR output to the 144mhz relay then to the transverter, similarly when 2 (432) is selected the controlling relay will switch the input to the 432 relay.

Re: [Flexradio] spam: Tune question
Dan, When working the dx contest on 80, I was moving up and down the band so the antenna tuner needed a touch. It was confusing to me to have to interchange A and B to do the tune. Version 1.8.0 tunes on the transmit VFO whether it is A or B. Svn 917 just tunes on A. So I listed it as a bug, but it might just be a preference. Tom Dan Scott wrote: Tom, When working split (DX - 40) I normally only tune the transmit once, then tweak the receive throughout the QSO. Having the transmit side be the default for tuning could make me more prone to messing up. I excel at messing up, so anything the help avoid that is good. I do use the AB feature to do the first tune of the transmit frequency. This allows me to verify that the frequency is available (not in split) on my end prior working the split. Once the frequency is know clear, I'll swap the A and B VFO and then hit split.

Re: [Flexradio] spam: Tune question
Ahh.. I was misunderstanding as well. I like swapping the A and B around, but as you said it could just be preference. On a contest I really only listen to see if other stations are working the same station, if there are not many I'm that one asking if the freq is in use. But if working split in a non-context, I do ask if the frequency is in use. I guess I'm in the habit of doing the AB thing and would not have noticed the bug. 73, Dan Tom Thompson wrote: Dan, When working the dx contest on 80, I was moving up and down the band so the antenna tuner needed a touch.

[Flexradio] USB Interface Problems
I recently acquired a USB Interface cable from another Flexer and am having some problems with my SDR-1000 when using it and want to make sure it isn't some cockpit error or something (I don't think there is any problem with the USB Interface cable). My SDR-1000 (early 1W 3 board stack with RFE and case added) has been working well with an PCI add-on parallel port adaptor. I installed the USB driver from the Flex-Radio web download page and selected the USB adaptor checkbox in setup. At first, things worked well - then I switched the preamp settings and the noise floor dropped way down and all signals disappeared. Changing the preamp to various settings had little effect. I then turned the PowerSDR console off and on several times and finally normal operation was restored. Subsequent changes to the preamp setting worked normally and did not result in this same behavior. Listened to various bands for a while and decided to try transmitting. Plugged my UB802 preamp in and PowerSDR reported that the USB connection was gone. I exited PowerSDR console and then noticed a dialog box that stated that the USB interface had been disabled (box came up under the PowerSDR console). Decided to reboot my computer in case something was messed up in the USB connection. When the PC was back up, started PowerSDR again (after power cycling the SDR-1000). Went into Setup and checked USB Interface box again. Turned on PowerSDR, no signals on the panadaptor and now the noise floor is at -65 dBm (normally was around -120 for the band I was on)! I can hear relays clicking when I go from Standby to On in PowerSDR but no impact on display. Exited PowerSDR and restarted. Now it is working fine again...

Re: [Flexradio] USB Interface Problems
It sounds like low voltage on the USB port. I assume you are using the internal one on the computer mobo? If so. You can try to get an external USB bridge that is powered from an external source (wall wart) and see if that takes care of the problem. RF getting in the USB cable will do it too. Putting good ferrite beads on both ends usually takes care of that problem. Or, you can just go back to the parallel cable. -Tim, W4TME - -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Kurt Vangsness Sent: Monday, March 05, 2007 12:02 AM To: flexradio@flex-radio.biz Subject: [Flexradio] USB Interface Problems I recently acquired a USB Interface cable from another Flexer and am having some problems with my SDR-1000 when using it and want to make sure it isn't some cockpit error or something (I don't think there is any problem with the USB Interface cable).
