Wow I was looking for that info for some project I am working on.. You never know where some of the info you need will be poping out from From: Steve Zingman Sent: Tuesday, October 06, 2015 11:17 AM To: Steven Donegan Cc: app_rpt-users@ohnosec.org Subject: [App_rpt-users] SA-828U 'COR' I can confirm the 828 has the second harmonic on my IFR 1200S For RUS you want pin 1 of the MIX2009 audio chip.

There is a note about a module using the same RF circuit on Doug's HAMVIOP site. He suggests a filter. REQUIRED if you are going to drive a amp or even connect it to a antenna! 73, Steve N4IRS On 10/6/2015 9:13 AM, Steven Donegan wrote: Thanks. For my first full duplex repeater (for test/learning purposes) I am going with 2 of those modules and a 6 cavity duplexor (likely of the 'notch' variety). If it works out may put my Mirage BD-35 on the TX side before the duplexor and get ~16 watts for giggles.
