I am using the LP-Pan on the K3 IF and its clock runs at 8.215x4. Actually, the later models of the LP Pan run at (8.215-.006)x4 = 8.209x4 = 32.836 MHz. LP-Pan set up for radios other than the K3 have a different LO to suit those radio's IF.
Minimum sampling rate needs to be >2x the IF frequency. ------------------------------ Message: 4 Date: Sat, 23 Apr 2011 13:27:15 -0400 From: "Igor Kosvin" <[email protected]> Subject: Re: [Elecraft] Info on K3 "IF OUT" To: <[email protected]>, <[email protected]> Cc: [email protected] Message-ID: <006e01cc01db$b2a38bf0$17eaa3d0$@[email protected]> Content-Type: text/plain; charset="us-ascii" John, Something is confusing in your post. If you want to sample IF directly, you would need ADC with sampling rate of at least 18MHz or so. (more than twice the 8.215MHz IF of K3). Your 192kHz doesn't make sense. P3 digitizing at 60 MHz because they want to allow using it with other rigs with IF up to 21 MHz or so. Maybe you can explain your setup in more detail. 73, Igor, N1YX 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kW?, 144-1.4kw, 432-100w, 1296-testing*, 3400-?
