Hi Wes The chokes do a few things. For transmitting, they keep the RF off the feedline. It is critical for RX and TX.
Just as importantly, they keep RF and Noise off the feedline while receiving, and this is what you want. The quieter you are, the more you can hear. Common Mode Currents can raise make it harder to hear weak signals and I have seen and heard this with my own ears, as many others have. How about I reduced my 80M noise floor from S9 to lower than S6. I'm not sure on 160M as I didn't really get going on 160 until after I was loving chokes. I now buy them in lots of 50 in bulk from Digikey. Read these pages. This is where I started a long time ago http://www.yccc.org/Articles/W1HIS/CommonModeChokesW1HIS2006Apr06.pdf. Well worth the read. Next, read Jim's stuff http://k9yc.com/2018Cookbook.pdf He is part of this group, and I know he will comment at some point.
