Hello Group, I'm hoping to get some "elmering."  Reading down the feed, I see some of you have a Neptune 100 and have a way to connect it.

I think I've gotten myself into a bit of a jam by trying to shove too much signal thru the Pure Signal Input on my Plus Board. I Used Tony Albus' 3-way and thought it would be sufficient.  But I think it was only 40dB instead of the 60dB I think is required.  Now I can receive but transmit is unintelligible garbage. Not even enough to trip the N100 amp to switch bands. So I have 2 questions. 

First, which board(s) will I likely need to replace? (I can see no issue on close physical examination). 

Second, what is the bullet-proof way to hook up the N100 with feedback to Pure signal? I can't see myself going beyond 100w output. An off the shelf solution would be ideal. (I'm anxious to get up and running.)

So it's simply bringing the N100 in to work with the HL2+. I've found I really need to dial back the output or it pushes the N100 up way too far... Hope all that is clear.

Thanks in advance,
Chuck
