Thanks Larry, By the way, since I already had a Presonus Firebox, I am using it for the interface to the LP-PAN. I did find a mod (100K resistor), while poking around the unit, that lowers the spur about 20db.
If you or anyone else has interest, I will try to find the picture I took and give details. The spur is still visible with pre-off and att-on, but with pre-on and att-off, it is below the noise. That said, I haven't recorded into the Firebox, so I don't know if the mod had any negative effect on the audio input. My guess would be no. 73, Bob -- View this message in context: http://n2.nabble.com/K3-Utility-and-LP-Bridge-Correction-tp4598240p4600893.html Sent from the [K3] mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
