Hi Doug,
<div>I have the BF888S but when transmitting, I am getting RF feedback. I suspect that’s what you meant by motorboating in your article. When you placed a .01uF cap, did you put it in series with the PTT line or parallel across PTT and ground? I assumed
that the PTT line was a DC signal so I thought that the cap in series wouldn’t do anything. I have to run out to RS to get the cap but when I get back I hope to install it.</div>
<div><br>
</div>
<div>I got the URI, and the BBB all set up, just the RF feedback.</div>
<div>Thanks again.</div>
