So I have been reading around and have not really found a concrete answer, what would be the optimal 4 ports to use if I am mainly using this for a receiver and to transmit once and a while? Mainly im looking for what typically do users choose, ? Also, when the do the HF mod what port is that on RX\_1 L or the wideband? Again my intentions are general purpose.Thank you for your help and insight!

The results WERE ASTOUNDING!!!

> Okay, since Friday’s BIG news about the RX1\_L Port modification, some were probably wondering what the RX1\_W Port looks like…Well, I’m here to impart that information to you and show you the results… First off, the mods I did were to the RX1\_L Port (shown in the yellow circle) and RX1\_W Port (shown in the red circle). All you need to do is remove the coils from these two spots and you’re DONE. No more mods necessary (for now, later on when there are apps that support two receivers, you can do t…
