Audio detection circuit to generate 'COR'
Steve, Be aware that those transmitters are dirty. 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:

Steve COR or actually RUS "Receiver Un Squelch" is available in that radio. You have to unsolder the shield to get to it.

I can confirm the 828 has the second harmonic on my IFR 1200S For RUS you want pin 1 of the MIX2009 audio chip. (under the shield) On 10/6/2015 9:30 AM, Steven Donegan wrote:

Hi guys, Yes, I also can confirm that these modules have DIRTY transmitters and RF synthesizers...And, their -loud- 2nd harmonics fall squarely in the busy 800MHz business/public service band. So, be careful with them, or you may have unwanted visitors knocking at your door!!! Without proper filtering, even with a small antenna, I'm sure their 2nd harmonic can be heard for miles! Personally, I wouldn't put a lot of effort into building a repeater with these--my experience has been that they're not really usable for more than a "back yard" repeater (meaning perhaps 1/2 coverage), due to high synthesizer noise--you'll never get the receiver to hear very well. As with everything, you mileage may vary--have fun and experiment! That's what ham radio is about! The nice thing about this hardware is that it's dirt cheap! BTW, I'm specifically referring to the Dorji DRA818U/DRA818V modules here, of which I've got several. 73, David KB4FXC On Tue, 6 Oct 2015, Steve Zingman wrote:
