Hi Charles. When running iSDR app on my iPad the spectrum base line is off the bottom of the screen. Is it possible that the next release of ISDR that could be...
Hi Philip, It is good to hear from you again. I will definitely try to address this in the next release. I plan to be adding FM mode soon. I may need some more...
Hi Charles. No it's the green spectrum, the display of input. When there is little or no signal it is off the bottom of the display. This is not a problem on...
I'll look into it. Also, I've wondered if it might also be nice to have a logarithmic scale (vertically), since signal strength is actually being displayed...
Hi Charles -- Yes, please do the log scale!!! I would like to use iSDR as an IF panadaptor for pointing and tuning up my microwave rig, and sun noise and...
Question Does setting the center frequency send a command to the attached SDR radio ( i.e. softrock ensemble II) to set its LO?? or is this for iSDR display...
Hello Paul, Thanks for your inquiry. As you suspect, there currently is NO iSDR support for direct control of an attached SDR radio/QSD device. iSDR just...
In the mean time, here's an iSDR external tuning solution that I'm considering: http://sdr-kits.net/PAOKLT/PA0KLT_Leaflet.pdf This Si570 VFO kit has a tuning...
There you go. What you see there in the PA0KLT kit is >90% of what is needed (assuming that ucontroller includes an RS-232 port) to create an Apple SDR ...
Hi Charles -- This is just to start a new thread on the log scale idea and to add a comment to my earlier posting: The reference level (as it's called in...
It's even simpler than that ... the ensemble RxTX SDR already has a USB interface to control it's VFO ... the only new hardware needed for direct iSDR control...
PS: The reason I mentioned the kit is that it works without any new iSDR interfaces, and also without lugging around a PC. The tuning controller and display...
Your point is well taken. The kit would be much smaller and handier than lugging around a laptop just for QSY. Regarding my tangent comment related to an...
I'll definitely look into the reference level. It would also probably address Philip's request for displaying weak signals currently not visible on the...
thanks all for the info.. it has spurred the desire for additional info Q1...if a powered usb hub with multiple device is attached, is the ipad able to 'see'...
Hello Paul, Thank you for the questions. Here's what I can tell you... Q1...if a powered usb hub with multiple device is attached, is the ipad able to 'see'...
Is this discussion pertinent to expanding the tuning range of the isdr program? It was my understanding from the description that the iSDR will accept a...
Hi Bruce, The band width over which iSDR will tune is determined by the sample rate that Apple uses in its iOS devices. (iPad with USB adapter may prove to be ...
Thanks for the comprehensive and comprehensible response, Charles. I look forward to the future developments, whenever. For now it is fun just to show off to...
I don't know if you are familiar with the 'SDR Radio Console', but it has a remote capability by which you can access a variety of radios via the Internet and...
hi charles yep...that is exactly what i had in mind for... i just received the ipad camera adapter which brings out the ipad usb interface i have seen reports...
update i was able to use my iPad by connecting the camera usb adapter connected to griffin iMic connected to the softrock ensemble ii rx this setup allowed me...
I'm curious where you found the specs for the microphone input. That kind of information is usually very difficult to find... and as usual I'm not finding it. ...
Would this be the text you're referring to? "(1) 3.5mm stereo headset/headphone/microphone jack" That is almost certainly describing the same 4-conductor...
Thanks, Charles. Yes, your quote was what I was referencing. I came to the same conclusion as you did regarding the input jack. I don't know if something can...
Bluetooth might be an option, but one with trade-offs. For me, the most serious trade-off is latency. The audio path through iSDR adds almost 100ms of signal...
