Introduction to using the MFJ-993 Intellituner with the Icom IC-7300 

Three antenna tuners to transmit (Rig,MFJ,Heathkit) must drive you crazy!

Why didn’t you mute the radio?

Hi good afternoon, I have the same tuner but I does not tune with the preamp on and if I tune a frequency with the att on, when I transmit with the pream the tuner think that iam tuning again,what can I do?

I find I need to power on the 993 after I power on the 7300 or the tuner doesn't work. Is there some setting I have missed? Thanks for the video.

Where is the MFJ in your chain? You use 2 tuners?

thanks for this video. i know its been a long time ago, but i have a question.. i haave a similar unit, and recently got an rf amp, so this tuner cannot handle the power output... the question is can i have two tuners, this one and a HFT-1500 connected together plus that amp into a MFJ 1700C Switch? and how could i do this with the ICOM 7300

I was always told to have the Auto button pushed in when using the interface. Wondering why you don't do that?

Hello, Nice Video. Can you tell me the Pinouts for the tuner to the ICOM cable?

I realize this was 3 years ago, but this tuner is at a nice price right now. Do you know if it will tune without input from a radio (sensing RF), I have a Xiegu G90(20w) and an old Ameritron als 500m and am trying to get things running, even to the point of using a foot switch to key the old amp. kd9oam.

I have a MFJ-993 too. After you tune up with low power, if you talk with SSB with 100 watts, do you find the frequency display on the 993 go erratic and also change the SWR while your speaking. With CW it works fine. SSB drives the tuner crazy. Do you have the same results?

ok so i guess after i hooked up that wire that came unsoleried from my molex connector i got my tuner to work go ahold of someone in san jose and im in the central valley so that seems to work ok for me for just a wire antenna.

Trying to figure out how to do this with the IC-9100 (key up method)

Has anyone noticed any difference (993B) not 993, how well it will match at 150w vs. 300w. I am finding I at least on 80m with balance line going to the center of about 125 feet on each side, I have not seen any improvements.

Why two turners ?

Funny thing I am able to tune 6 m on this antenna tuner it works and others have done it too I think

i had a wire come unsoildered again from my molex i geuss thats what that plug cable again so everyone if you have problems not tuning check to make sure no wires have come disconnected i wasted alot of time trying to figure out what went wrong .

good day i was wondering do i need to run a jumper to my antenna tuner from my icom? it appears to tune with low swr though no problem there have a nice day kf6sif .

how or can this tuner be used as an swr meter without tuning the antenna. basically what im asking is can it be used as a true swr meter alone?

Can the MFJ turner ground be connected to the Icom 7300 ground? I mean to put a direct cable from the transmitter to the coupler? Thank you

I have a 993B & everytime I keyup it says 'Huh?, increase power'. I have an ICOM 7100 running 15watts. I have done a total reset and still get the same results. Anyone have any idea why?

The manual sounds like you can set a swr target of 1.0. I can only find how to set it for 1.5 or 2.0. Do you know how to set it for 1.0?

Do you have to turn the IC-7300 internal antenna tuner off to you the MFJ-993B?

Hi did you find out what the power down fail was ...great vid

My exact setup. Although i put a ANC-4. Damn neighbors.

How does one disable the internal tuner to use the external one ??

How do you put it in the 300what mode and 150watts

Hi I noticed the problem you had a 7.210MHz. I have the same problem but no other means to sort it like you did. I am running a GWHIP 421 Triband resonant end fed antenna which is resonant on 40, 20 and 10M. So any idea why the tuner fails on 40M?

Can you tell me how is the interface cable you made?

whats the difference between a 993 and a 993B ?? newer model? g4vvq uk

Hi there do you know with an IC 7000 and a TS 480 if you need an interpase box or just a lead from radio to tuner....Fred in Uk g4vvq

Which interface cable will I need for that setup?

Thanks for the video. When I press the Tune button on the tuner, it beeps at me and displays the message "Huh? Increase Power". If I press the Tune button a second time, it tunes properly. Auto button is out on the tuner, power output of the radio iss 100w SSB. Any idea what's causing the initial error message? Also, it I press the Tune button on the radio, it uses the internal tuner and not the MFJ tuner.

Sorry.but cant here from squelch being open..too noisy.

Sounds like a diesel truck when it’s tuning! 😃

Factory reset to test power down pass www.manualslib.com/manual/859243/Mfj-Mfj-993.html?page=29 Also more than 4 relays- other than that great video

bloody noise can`t hear you very well.

POOR photography. Be ashamed, VERY ashamed.

First thing you want to do is use some common sense and turn the radio volume down!
