Hi, 1. Fn button is explained in the article. Single click toggles the RIT, doubel click swaps the vfos, holding it down resets both the vfos. 2. You can use the JBOT amplifier. 3. There are no band pass filters! Rtfm. There are two low pass filters. - f Sent from BlackBerry® on Airtel -----Original Message----- From: "pakdeDar" <pakdedarmantaoye@xxxxxxxxx> Sender: minima-bounce@xxxxxxxxxxxxx Date: Sun, 19 Jan 2014 10:55:08 To: Minima Group<minima@xxxxxxxxxxxxx> Reply-To: minima@xxxxxxxxxxxxx Subject: [minima] More detail Minima operation Dear Farhan, Read your Minima article and look at the schematic, would you please explain more detail how to operate Minima, such as : 1. What is the function of FN switch, tune pot, RST switch.I guess the Mode, Band select to enter by FN, but only guess... Is 100k - lin pot fine enough to tune in certain band ? 2. I even can not identify what is the RP PA in the schematic ?? I understand other block otherwise. 3. What band the BPF in the front end ? How they are selected . Maybe could be traced the operation from the controller sketch, right Farhan ? Sudarmanta Kaspa-kaspaanlayauw ®
