That's correct, mark. I should have said : check on 18 mhz. That's the edge case. - f Sent from BlackBerry® on Airtel -----Original Message----- From: Mark G0MGX <mark.g0mgx@xxxxxxxxx> Sender: minima-bounce@xxxxxxxxxxxxx Date: Thu, 30 Jan 2014 07:43:47 To: <minima@xxxxxxxxxxxxx> Reply-To: minima@xxxxxxxxxxxxx Subject: [minima] Re: tx output spectrum Yes, I can do this later on today. I thought we used the lower frequency LPF up to 15MHz and then set BAND_HI to change to the 30MHz filter above that frequency?
