[Elecraft] iSDR app and KX3 not working

[wb4jfi at knology.net]

Hello there, I might be able to help a little.

I assume that you have the KX3 analog I/Q outputs connected to the Griffin 
iMic "IN" jack, the iMic plugged into the Apple USB camera adaptor, which 
then plugs into the iPad connector?

By new generation iPad, do you really mean the iPad 2, or iPad 3, or Mini? I 
see you mention both an iPad 2 and a new generation iPad, they aren't the 
same.

I have been using the iMic and Apple adaptor for well over a year, including 
with an original iPad, iPad 2, and iPad 3.  However, I do not have a KX3 
(yet).  I'm using my setup mostly with Softrocks, but the KX3 generates 
analog I/Q signals similar to the Softrock, and I've heard others use that 
combination OK.

The first thing that I would check is that you are connected properly to the 
KX3 analog I/Q outputs.  That would be my guess if you are loading iSDR 
properly, and everything else seems OK.  Also, can you see the "demo" or 
prerecorded spectrum in iSDR?

You will not have control over the KX3 from iSDR, as in tuning the KX3, etc. 
A friend and I have been working on a way to add that for a while now, using 
an Arduino and ethernet to connect to the KX3 and send CAT commands from the 
iSDR.  I've been stuck trying to get a wifi version running, but wifi on the 
Arduino is a pain, and I've been having house work done that has unfocused 
me for two months now.  Charles is aware of our work.

Subject: [Elecraft] iSDR app and KX3 not working

I am in need of advice. I have the newer iPad 2 and am having no luck 
getting it to work with the KX3 using the iSDR app. I am using the Griffin 
external sound card and basically doing what the uTube video I Googled is 
doing but all I am seeing is noise, no stations and the iPad has no control 
of the KX3. Seems that the KX3 and the iPad are not talking to one another. 
My first question is, has anyone used the new generation iPad successfully 
with iSDR? Any tricks to get it to work? Thanks for reading.
