Channel: Ham Radio A2Z
Date: 2020-04-12

NOTICE:  In July 2021 the channel name changed from HamCuredSmoke 
To Ham Radio A2Z.  All of the earlier videos (like this one) are still available.


This time we'll take a look at connecting an external antenna tuner to the IC-7300.  We'll also look at how the IC-7300 recognizes an external tuner.  Icom doesn't release much information about how the external tuner connector works on their radios.  I have used both the LDG IT-100 and the MFJ-939 tuners with my radio.  I am using use the MFJ for this demonstration.
A number of people have done some experimenting and come up with various interfaces to use the radio with generic external tuners.  Here are a few links that I have found useful:
