Its nice they included this. In general, an antenna tuner that can match a 3:1 mismatch on a lower frequency can match much larger mismatches on higher frequencies due to the linear relationship between frequency and reactance. That means that the limiting factor on higher frequencies is not the tuning range of the unit itself, but the voltage rating of the capacitors. That's why the power has to be decreased if you tune a larger mismatch than the unit was designed for.

For Yaesu FT847 & FC 20 ATU owners try this The fix is on in one of the menus in the Yaesu 847. After this mod the 847 will tune up to a 7:1 insted of 3:1 The first thing you need to do is get into the service menu. You do this by holding down the three buttons on the mic and turning on the radio. The first menu will be Fm-51 do not change that one. Rotate the sub-tune knob until you see the menu that says SWR 3.0 to the left this you will see two small numbers or numbers letter combination. Rotate the MEM/VFO CH knob until you see 9A then push the menu button and you are done.

I tried a G5RV and didn't like it much. I Put up a 80M dipole and fed it with 450 ohm twin lead and tune it with a "true" balanced tuner. A BT-1500A replica I build to be exact . Much more satisfactory performance even with an amp. Then went one step further and put up a horizontal closed sky loop fed with twin lead ladder line at 40ft cut for 160M. Tunes great, a top line antenna and now my go to antenna for any application! Cheap, easy to build, low noise, if you have the space to pit one up! You can still find old Johnson Matchboxes that work quite well with these at reasonable prices!

I would guess the screen SWR indicator is disabled in this emergency mode. I suspect an inline SWR meter would show the same mismatches as when not in emergency mode and thus inefficient transmission, with considerable reflected power, hence to 50W limit to protect the PA from overheating.

I wonder why they included the emergency feature to operate the IC7300 at a much higher SWR and just didn’t include as standard inside the antenna tuner. My only assume is that it puts a lot more stress on the final output transistors, the capacitors and inductors in the auto tuner. This maybe this is OK for a short time, like an emergency but if used constantly it will cause prematurely age the components causing reliability problems in the long run, even though it is operating at half power.

Please remember that this is coupling the radio into the antenna. It is not changing the antenna in any way and hence not "tuning" the antenna. It's always best to have a resonant antenna on each band but if this extension to the default matching capabilities of the 7300 lets you get some power out on a band that otherwise you couldn't - go for it. 73 Ed

this is a nice trick for the 7300. I run 50 watts or less with mine. I got a tube amp if I want more. for portable use like POTA this is great . I have used a 9:1 random wire antenna and it tunes all bands. with end fed half wave with 49:1 you only get some bands and with emergency mode you can tune over 3:1 SWR. like using 17 and 12 meters . when tune for 40,20,10. etc. depending on cut length of wire. This trick is in the extended manual not the paper one. you do the same in menu to turn off E mode. 73's

I'm looking for a new radio and the IC-7300 is top of the list. Thank you for the videos about this radio. I like the way the menus are interactive rather than a simple list. The size of the radio is important, I don't want to be fiddling around with tiny buttons. Apart from that, Icom or Yaesu are both very good. It seems to me that if you have been using your IC 7300 in "emergency mode" for a couple of years without problems then all is ok. Perhaps it's a selling point for the USA where emergency communications forms part of the Ham culture.

Peter, my preference is to use thick well shielded coax connected to a quality waterproof balun mounted near the antenna terminals. When disconnecting the balun from the backyard dipole, there is no sign of unwanted signal via the coax line connected to my Icom R8500 or 8600 receivers. I use RG6 Quad Shield 75-Ohm coax for my HF and VHF SWL work. The extra coax shielding makes ferrite chokes unnecessary at my receiving location. Not happy with relative thin diameter coax wrapped around a toroid ferrite. The balanced twin lead and coax in your KZbin video is also exposed to the large amount of rain that the UK typically experiences. A properly balanced receiving antenna (dipole, Yagi, log-periodic) with quality waterproof dipole terminal balun mounted as far away from the house and street power line noise sources is optimum for maximum practical SNR. The vertical axis noise floor on receivers like the Icom 7300 spectral display will be usually lower with high-end properly balanced antenna receiving systems. Horizontal polarisation also helps increase SNR. There are always better ways to do things.

I use a random wire, around 30m, with a 49:1 balun. In the shack, I initially use a manual tuner (Kenwood AT-230), to adjust my compatibility with 5W CW, followed by the rigs ATU. This gives me all the bands I want, 160 to 10, and I also seem to get excellent reception. Any comments on this setup regarding the security of my rig? There is no evidence of RF in the shack.

A small resistor can allow you to do this at full power level as well, which, for reasonable antennas (ie, not exactly half-wave), you can operate at 100W just fine and not have to reboot into "emergency" mode. Google for pc5e 7300 atu mod, you will see. The mod doesn't change the SWR metering, only the threshold of which the radio will not attempt to tune. One little resistor later and you can run that built-in ATU anywhere. Just be sensible about it and don't torture the radio where it truly should not be used.

Interesting option. Thanks for sharing. Very strange that Icom call this feature 'Emergency Tuning'. If I used a half size G5RV, I would definitely use a remote aerial matching unit between the line isolator and the ladder line. This would remove the losses on the coax due to to high swr. You could also use full power from the radio.

I had a Yaesu FT-991, and on my Off Center Fed Windcamp WA4 multiband antenna which didn't tune all inclusive bands because of a 3:1 SWR range. Also my Yaesu FT-891 with the Yaesu FC-50 Tuner has similar results. I have the switchable MFJ automatic Antenna Tuner Extender in line which helps the matching to some extent. Now with my Yaesu FT818nd and an external AT-100 Tuner and a separate Micro 50 watt multiband amplifier, running 50 watts, I believe it is able to tune the antenna on all bands, I presume because the external AT-100 Tuner has a wider SWR range matching ability, and that is with the amp only accepting a 2:1 SWR, or lower. I don't know of these two full size Yaesu FT'991 or FT-891 transceivers have a similar feature to help SWR matching as the Icom IC-7300 does? 73 de W2CH Ray New Hampshire. 😊

Hi; I have seen thet your 7300 display has a white line, Do you know if it is easy to change the display for a new one,? I know someone who has that problem, it is not a serious problem but it would be good to change it Regarding emergency operation, I will tell you that really 3dB less power is not a serious problem because it is only 1/2 "Santiago" on the s-meter, and as you say, it is possible to work in other bands In any case, I do not understand why ICOM did not put an ATU that can work with 4 or 5 SWR, for 100W. I think that the voltages generated could be alleviated with some better relay that is not much more expensive. Sorry for my bad english

Have you been inside an ic-7300? The toroids are tiny and they get very hot, exactly the same as any balun which has much larger toroids. An ATU is simply lots of different sized baluns used in conjunction with each other until there is a good swr match. It may be using 1 toroid or 8 toroids or any combination of several to achieve a match. However, they are tiny and heat is a big issue at 100w. The 50w restriction is not for human safety, rather mechanical safety.

The radio drops power to 50 watts to protect the internal tuner. By entering emergency mode, the firmware is set up to allow the tuner to use component values pushed to the limits of the tuner. These types of auto switching LC tuners usually have built in self protection to prevent an inductor or capacitor from seeing too high of a voltage. If the radio ran at the full 100 watts, it would most likely smoke the internal tuner. so, by dropping the RF power, they can "fudge" the ratings a bit to allow for emergency use into a marginal antenna.

Would you get the same result if you just reduced power to 50w and stayed in non-emergency-regular mode? 73, KB3NG

No you need to change the ATU mode.

Thanks for sharing this, but the Emergency Tune function isn't "hidden". It's right there in the manual and menu. I use it sometimes with my 7610, but normally don't need it (I have an external high-power LDG tuner). I find it useful most when running FT8 or WSPR in the field when my antennas are far out of tune on certain bands, or like your G5RV, isn't resonant on the band at all. BTW, there is NOTHING wrong with non-resonant antennas. I've been using them for years with outstanding results. There are special cases where non-resonant antennas actually have gain over a standard resonant 1/4 or 1/2 wave antennas (the Extended-Double-Zepp is one good example that I use a lot). The only "trick" is to use feedline that isn't too lossy into mismatches, like twinlead.

I think the hidden part is that Icom decided to call it “emergency” whereas it is simply “extended capability.” Thanks for sharing.

@watersstanton Perhaps somewhat misnamed. But OTOH, they could've called it "Changes tuner into a mode that allows it to match 10 to 1000 ohms but reduces power to 50W" and someone would complain. Just how hams are, I'm afraid. 🤣

👍Thanks for video Peter. I had spotted that Emergency Mode option in the menu but never tried using it. Wrap that SO239 with self amalgamating tape and insulating tape and it will last the winter no problem. I was curious to know what type of core you used for the choke on the co-ax? Taking a punt it's a FT240-43.

An iron ferrate terminate for the antenna will give nearly 2x the signal capture than most antennae I have found. Plain old protein from household food is comprised almost entirely of ferrate iron. Connect 62 feet or more of heavier gauge copper wire into a jar of any peanut butter which is high in iron, run the cable out a window and place the jar at least 8 or 10 feet above ground or on the roof. You will be amazed with the result.

So basicaly instead of mesing around in menus selecting Emergancy and having to rebbot the radio, just drop the power to 50W on the bands that wont tune and they will tune.

No, no no! Just turning power down has no affect. You need to go through the reboot procedure.
