The core hardware<br>> (i.e. radios) is all fairly similar, the biggest area of difference being<br>> if you have a PLL type exciter, versus the simpler crystal-multiplier<br>> type. The PLL exciter uses direct FM, whereas the multiplier version is<br>> phase-modulated FM...Boiling this down, it basically means different audio<br>> drive levels (and equalizations) are needed. The PLL exciters were<br>> specifically for VHF hi-band repeaters. I've heard rumors of PLL hardware<br>> for exciters other than VHF-hi, but never personally seen any.<br>> <br>> Also, you will need a simple level shifter for squelch COS signaling from<br>> the Mastr II. ...For simplicity, an aftermarket PL decoder/encoder is a<br>> good method, if PL capability is needed.<br>> <br>> One thing to also note is that the exciters can be VERY wide-band--so,<br>> it's very important to using a properly filtered TX audio source. URI or<br>> RIM style audio adapter already include audio low-pass filtering. If you<br>> want to use a unfiltered USB FOB, make sure to follow it with a LP filter<br>> to stop DAC aliases, etc., which could wide-band modulate the exciter!<br>> <br>> About the single best resource I've found on the Internet for all things <br>> Mastr II, Rangr, etc., is the repeater builder website, here:<br>> <br>> http://www.repeater-builder.com/ge/geindex.html<br>> <br>> 73, David KB4FXC<br>> <br>> <br>> <br>> On Thu, 26 May 2016, Roselito de los Reyes via arm-allstar wrote:<br>> <br>> > Good morning!<br>> > <br>> > I was told that simpleusb does not work with this repeater.
