Geoff, This topic was kicked around about two years ago and basically Elecraft said it they had no plans to provide access to the IQ ckts in the K3. I'm not sure if there may be future plans to add this for the P3? Since there is no hardware path then no firmware upgrade can switch it to a connector. I would have loved direct digital access to the IQ ckts instead of buying two LP-Pan, which duplicate the IQ mixers in the K3 but provide base-band audio output for connection thru a soundcard.
I modified my K3 sub-receiver to breakout the 1st IF so I could connect a LP-Pan to it, as well. From the two LP-Pan I connect a four-port soundcard (M-audio Delta-44) for running dual-receive diversity reception on Linrad SDR sw. If I only want to use one receiver, I bought the emu0202 soundcard, since it can do 192-KHz bandwidth. I bought the LP-Pan used for about half-price and also the emu0202. I found the Delta-44 cheap on Amazon.com. I document all this here: http://www.kl7uw.com/LINRAD.htm Its an unfinished project at this time. 73, Ed - KL7UW ------------------------------- Date: Wed, 9 May 2012 00:03:01 -0400 From: Geoff Wolf AB3LS <[email protected]> Subject: Re: [Elecraft] RX I/Q output planned or thought about for the K3/P3?

I suppose the thing I'm trying to get at is a direct I/Q line from the K3... Whether a software update is possible to add this to the current Stereo Line-Out jack (on the back of the K3) or not. 73 DE AB3LS 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-QRT, 1296-?, 3400-?
