Icom 7100 rear sockets original configuration

Icom 7100 have 2 antenna sockets,

Ant 1 –  HF, 50 and 70 MHz,

Ant 2 –  144 and 430 MHz

 

John M0UKD made this change and wrote about his experience.

You can download a copy of the Icom 7100 user manual here.

The most difficult part is finding a source for the 2 hole N-Type sockets, I sourced one from Ebay.

Here you can see the chassis socket has been changed to N-Type.

  1. Very good idea ! I did it and doing it on every transceiver that goes in my hands, using teflon insulated/gold plated “N” socket. I am also changing the HF SO-239 socket with a teflon insulated/gold plated (better quality) socket. As the transceiver is open, I am soldering the central pin of these connectors, as I do not trust these “spring contacts” used by Icom.
