This question is posed to those who have experience with an ICOM 7300 and MFJ-1788 loop antenna. I am trying to figure out a way to better tune my MFJ-1788 loop antenna with my Icom 7300. The antenna instructions for the antenna say to put an unmodulated tone through the antenna to any desired frequency between 10.1 and 29.7 MHz (between 1 and 50 watts). I tried configuring my radio mic to use the down button to act as a straight keying device for CW. But the antenna's separate tuner does not seem to work to adjust the SWR in CW mode. However if I use the RTTY mode, I can get things to work. Is this the correct way to tune the antenna on the 7300 or would the CW be better and how do you accomplish tuning this way? It seems to me using the RTTY to tune while on FT8 mode I will be causing a lot of QRM since it takes up a lot of the bandwidth and interfere with other signals.
