By design PSDR-IQ mutes the Windows default sound device when switched to transmit. This is different to the behavior of PSDR1.9-sr40, My Soundblaster card, which I use for Tx/Rx IQ, was installed as the default sound device so the Tx IQ was being muted when transmit was selected - hence no rf output. Changing the default sound device (in Control Panel) to be the on-board audio hardware has solved the problem. 73, Geoff G3WPD'This PSDR also has the fixed audio frequency feature to make image rejection easier.(C2) POWER SDR-IQ continued.PSDR setup Basic settings for PDSR-IQ with the USB Softrock.PSDR-IQ TX IQ rejectionPSDR-IQ is targeted to the frequency agile homebrew rigs like Softrocks with Si570,UHFSDR, PMSDR, 995X, etc.

Christos shifts the frequency in TX mode to give thelowest possible spurious signals. He says:- 'For 6.2 softrocks there is either the Si570XTall or the USBSynth that could be used. In my own 6.2 (I have three of them) I've added the Si570 board from Dave's WB6DHW Si570 little board and control it either via LPT or via his HSUSB board.If you insist on using a crystal on your 6.2 you have to use some other PSDR flavor since I do not supportTX under this configuration due to FCC/ITU regulations, you can read past posts on the subject and they could be enlightening.'

In theprogram folder where it is installed you will find 'receiveiq.bat'.If you changed the folder from the default you will have to edit the path inthis file.

Then dragging the file to the Start Menu will give a shortcut to it. IQmode is stand-alone, it acts as it's own SDR but the frequency has to be changedby moving the SDR Centre frequency. Using Dream in IQ mode it seems that the centre frequency is the statedtransmission frequency, that's what it works on, I find it works with a centrefrequency from about -1KHz to +12KHz of the nominal.Using PSDR at 48KHz sample rate, I RX Voice of Russia, quoted as 7325MHz in the listing, with acentre frequency from 7.304 to 7.337.

This includes reception on the centre frequency.So that equates to nominal frequency -21/+12KHz. This checks with BR-BR5akt on quoted 6.085MHz.In both modes you may have to toggle the 'flip spectrum' box inthe Evaluation Dialog to be able to decode a signal. Note my references tocentre frequency are relevant to those using fixed tuning or independentcontrollers. SDR programs with Si570s should be setup to compensate.Dream may be used in normal mode with PSDR and other software using VAC.For the baseband audio to be correct the SDR filter must be 10KHz wide.Using DRM with PDSR there is no confusion with frequencies. DRM's Input Spectrum/Waterfall shows the signal from 7-17KHz.

However, with no signal the displays do not look very different. PSDR offsets the LO by 12KHz forDRM. To get this same offset on the Input Spectrum/Waterfall with I/Q mode requires a LO offset of +6KHz, I do not know if this is relevant.

In I/Q mode I find it difficult to determine the 'correct' offset, it just scans and locks.Some PSDR setup with DRM73, Christos SV1EIAWhen the program is runningView - Station Dialog. Opens a list of DRM stations.

I use four Softrocks at the same time with thissoftware, using a sample rate of 8KHz, for fixed frequency radio monitoring.' Of course the combination SpecLab/Softrock is not display only. It can be used as demodulator with filtered / converted / inverted audio output, i.e.

You can use it as USB / LSB / CWreceiver. With some more fiddling, you can also use it as an FM / AM demodulator (the'dsp blackboxes' must be used to demodulate the latter).As a starting point, use the configuration 'Quick Settings - Image Canceling DC receivers (I/Q) - Then select one of the soundcard options.' But note this will work using as low as 8KHzsampling but with a narrow bandwidth. When you open the Spectrum Lab Components window after this, you'll see both inputs from the (stereo) soundcard go to the digital filter in the middle of the window.
