Re: [Flexradio] How can PowerSDR S-Meter be corrected to read S9 at -93 dBm on VHF/UHF?
Below is Tim Ellison's response from The FlexRadio Community<https://community.flexradio.com/flexradio/topics/how_can_powersdr_s_meter_be_corrected_to_read_s9_at_93_dbm_instead_of_73_dbm_on_vhf_uhf> > Tim - W4TME, Customer Experience Manager > That is not a feature of PowerSDR. If you have a 50 MHz signal source > that is calibrated to -93 dBm, you can re-calibrate the S-meter, but it > will be off for the HF bands. This means that PowerSDR S-meter readings currently are in error on 50 MHz and when used with VHF or UHF transverters. Until and if this discrepancy is corrected in the PowerSDR software, we must remember to add 3.3 S-units (20 dB) to the PowerSDR S-meter reading in order to give accurate S-meter reports above 30 MHz.

[Flexradio] How can PowerSDR S-Meter be corrected to read S9 at -93 dBm on VHF/UHF?
The IARU Region 1 Technical Recommendation R.1 defines -93 dBm as S9 on VHF/UHF frequencies above 30 MHz and -73 dBm below 30 MHz. How can the PowerSDR S-meter readings be adjusted to correctly indicate S9 at -93 dBm when above 30 MHz to comply with this specification?

[Flexradio] Interfacing VHF/UHF and Microwave Transverters to Flex 5000

[Flexradio] Flex-1500 and external frequency reference.
My GPS disciplined 10 MHz square wave frequency reference did not work with the Flex 1500 since the Flex 1500 reference input uses a bridge rectifier as a frequency doubler and requires a sine wave source. Since a square wave consists of a sine wave at the fundamental frequency combined with all its odd harmonics, a low pass filter will convert a square wave to a sine wave. I used RFSim99 to design a 3 pole Butterworth low pass filter. The RFSim99 simulation model yielded a frequency response curve with 1.7 dB loss at 10 MHz and 30 dB attenuation at the 30 MHz third harmonic. The filter was built into Altoids box: two 270 pF capacitors and a 1.4 µH inductor (17 turns of magnet wire on a T50-2 toroid core). The filter's actual frequency response measured with a MiniVNA Pro corresponds with that predicted by the RFSim99 model, and the Flex 1500 now works with this GPS frequency reference.

Re: [Flexradio] ADC L and ADC R Imbalance and Phase 2 Display
My Inquiry: My FLEX-1500 Phase 2 display is displaced outside the center circle to the lower right quadrant and the ADC-L and ADC-R readings show a 4 dB difference. However, the FLEX-3000 Phase 2 display is properly centered with only a 1 dB difference between the ADC-L and ADC-R readings. The FLEXRadio Knowledge Base article at http://kc.flexradio.com/KnowledgebaseArticle50298.aspx states that the ADC-L and ADC-R levels should be within 1 dB of each other, and that a mixer balance offset may cause the difference to be greater than 1 dB. FlexRadio Systems Support response on Apr 13 04:17 pm (CDT): Carol, I had a discussion with the 1500 engineer, and he says due to the way the 1500 internal codec has to work with the USB , that the phase2 is not going to be exactly like the 3000 or 5000 but could not explain the difference. So for now the phase 2 display is not an issue. He suggested that if the Gen/bal passes, it 's operating correctly.. - Dudley --- Dudley Hurry, WA5QPZ ___ 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.flexradio.com/ Homepage: http://www.flexradio.com/

[Flexradio] VAC not available in SSB modes?
I read this post and need to know if VAC is no longer available in SSB modes in PowerSDR 2.4.4. Those of us who run SSTV and on the 60 meter channels where both data and voice are allowed need to have access to VAC while in the SSB mode. Carol, KP4MD Rich - W3ZJ rich at w3zj.com Wed Sep 5 09:10:35 CDT 2012 Changing modes form any mode to an SSB mode turns off VAC1 even though "Enable for Digital modes. Disable for all others" is NOT checked. I need VAC1 enabled for all modes as I use CW Skimmer on CW and WinWarlber's Digital Voice Keyer on SSB both of which require VAC1. 73, Rich - W3ZJ ___ 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.flexradio.com/ Homepage: http://www.flexradio.com/
