[Flexradio] Calibration: Is this a bug in 1.4.5.18?
Is this a bug or a new feature? The Level Calibration of the preview 18 with -70 dBm signal gives me following signal levels on the Spectrum display with different preamp gains: Off: -70 dBm Low: -80 dBm Med: -70 dBm High: -80 dBm If I transfer the mdb-file from the version 1.4.5.16, all gain settings show the same -70 dBm. 73, Ahti OH2RZ
Re: [Flexradio] Recever goes dead
I recently had a similar problem. It turned out to be corrupted software. I removed the Power SDR software and download a fresh version. Everything is now okay.

I would say this happens about once a week on the average. I've had the radio on since Friday evening and sometime between 11pm last night and now, 6:15a, the receiver went dead. Turning the radio to standby and on again bings it back to life. This has happened with this radio with previews 14-18. It doesn't appear to happen in the other SDR1000. Anyone else have this problem? Maybe I should report it as a bug? Another problem I have might be a conflict with Microsoft Money. It seems when I run both programs at the same time I get a .NET error and PowerSDR shuts down. The next time it happens I'll try to capture the error. 73, John N1JM ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://mail.flex-radio.biz/pipermail/flexradio_flex-radio.biz/ FlexRadio Homepage: http://www.flex-radio.com ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://mail.flex-radio.biz/pipermail/flexradio_flex-radio.biz/ FlexRadio Homepage: http://www.flex-radio.com

Maybe, if you copied the entire directory tree somewhere else, then did the remove,then readded, a comparison could be made.

While tracking it down for Windows is a bit of a chore, it's at least feasible for PowerSDR.

I did not save corrupted program.

Good your point re. saving and analyzing the corrupt program. John It would also be good to note anything that Windows Add/Remove didn't do properly. (viz. your Windows Explorer stuff) As we move forward with different versions (particularly after the UI/backend split) having the automated install/uninstall/upgrade processes work properly is going to be a bigger deal, especially as far as customer satisfaction goes. Nothing like having to go in and hand tweak the registry to turn off would-be future usersgrin. Jim
Re: [Flexradio] Wav playback
Tom, I am not a programmer but as far as I understand the schematics of the SDR1000, the signalpass for playback has to go through the quadratur mixer chip for reception IC1 while the signalpass for transmission is passed through quadratur mixer chip IC2. Send/receive switching between the two chips is done by solenoid relays. So I have some doubts that you can receive and transmit at the same time. However, programmers can perform miracles and come up with surprising things.

Very difficult to calibrate the receiver. It would not calibrate at all on 14.200. I finally manage to calibrate it on 7 MHz. It seemed to try to use the noise level as the source. Consequently the noise level would be at -70 dbm, or -80 dbm depending on what the preamp was set at and the signal 73 dbm above that. 73, Dale AA5XE -- Government is not reason, it is not eloquence, it is force...Never for a moment should it be left to irresponsible action. – George Washington

Re: [Flexradio] Odd CW behavior

I can key half a dozen times and it works exactly right and then it will decrease in power by about 20%. The next time I key its back to full power. I listened on a seperate RX and there is clearly a difference in the tone that is transmitted as well. The tone is not as hard and it is not as loud in my seperate RX, so this is a real phenomona.

[Flexradio] GPS controlled oscillator
In reply to all those who have queried and asked for information on my GPS controlled oscillator. Before I give details, I would like to thank Mike Seguin,N1JEZ, for his help and patience with my questions on this project. I refer all those interested to articles by Mike and James Miller, G3RUH, and others, on GPS controlled oscillators, start with a Google search on N1JEZ, and work from there. All the information you need can be found relatively easily. Mike has very complete details on how to build a GPS controlled oscillator, including the pc board and the GPS engine, (but he might be running short). His information has a very good component list, which enabled me to source the parts easily. I found Digikey marvelous at supplying the components I needed. The unit went together very easily, even if it was my first go at soldering SMD's, however I made one significant change, in that I used a new Navman Jupiter T timing module part no. TU60-D120-041, as used by G3RUH in an oscillator, it was not cheap, and Navman tried to convince me into another item, as the Jupiter T is no longer recommended for new products, but it is still available, at the same time I purchased an active antenna. Download the tech data from Navman for the Jupiter T, its useful. I obtained a copy of TAC32 software, (Google search) which is extremely useful for testing, to ensure that the unit was receiving satellites and working correctly, and I ran the unit on the desk, into Tac32, for a month, to ensure that it was working reliably before delving into the innards of the SDR1000. There are a couple of problems with the GPS oscillator, the antenna, will need to be out in the open, where it can see satellites reliably, mine is on the roof of my office/shack under a weather proof cover, this means that you will need a long antenna cable to the unit. I managed to have one made with the correct fittings by a local marine radar/gps supplier, but you could make one yourself. Secondly, I have had a comment that the external oscillator, may be susceptible to RF, so far I haven't noticed this. Once the external oscillator change is made to the SDR1000, you need to go into settings and alter the clock offset and the PLL multiplier. Eric W: If you read this, I note that I can get 2 settings on the clock offset where the unit is in sync with WWV on 10mhz. If I use phase then the offset is -147 and the panadpter shows on frequency, but if I use spectrum I have to go to -220, to say I am exactly on 10.. Either way the difference is probably only a few cycles. My GPS oscillator, runs all the time, so when the SDR1000 is switched on, it is immediately on frequency, no warm-up, I haven't noticed any significant disadvantages to fitting the GPS unit. There maybe more spurs, but I am not observant enough to determine if they were there, before the mod or not. regards to all Ross ZL1WN
[Flexradio] [OT] Squeak flexes it's muscles
For those of you who are interested in the bleeding edge of Ham Radio, please take a look at the G3UKB Software Defined Radio console written in an object oriented computer language named Squeak. I want to call attention to the amazing work that Bob Cowdery G3UKB is doing. Please visit his pages often to see the progress he is making http://myweb.tiscali.co.uk/g3ukb/ Bob demonstrates the challenge he faces by showing us his approach which is both rigorous and disciplined in addition to being very advanced in both techniques and tools. He has used the latest-and-greatest design technique called UML (Universal Modeling Language) and included preliminary diagrams to show us how it looks. Is this software soldering? His most recent screen shot is an example of MixW on a dual-watch design http://myweb.tiscali.co.uk/g3ukb/digimode.htm I marvel at how Ham Radio has evolved from the skilled operation of lathes and metal bending brakes, to artistic skills in graphics design interwoven with logical skills in computer languages like Squeak :-) I hope that you too share the wonder of our hobby in the digital age.
