- This video demonstrates how to configure the cross band repeater function in the Icom 2730 mobile transceiver.
This feature will not be available in the radio's menu unless you activate it, as indicated in the video.
For some reason (an unintentional omission, probably,) the cross band repeater feature is not explained in the printed manual that is shipped with the radio. An addendum that explains this feature is available at:
www.icomamerica.com/en/support...
The addendum is somewhat vague. Hopefully, this video will explain the procedure more clearly.

Finally someone that made a logical and understandable feature of the 2730. THANK YOU!
Thanks a lot for this video! I've had my Tech license for a little over a week now and decided to try this out on my IC-2730. Works great!
I just bought this radio yesterday. Thank you for the easy instructions. I really like this radio.
Nicely, delivered! Major strength of this xcvr.
Great job on this video. I'm just getting into amateur radio, and easy to understand tutorials like this are great. Thanks!
I've only been using my 2730 for a short time, but I'm impressed. I upgraded from an iCom V8000 VHF only because of how well my old radio performed, and have found the receive sensitivity on this rig to be equal or better. My 2 gripes about the 2730 (and admittedly I may not have found the settings to control this) 1 - The button chirp seems to be sent through both volume controls, so pressing a key on the radio is extremely loud if both volumes are turned up. 2 - The HM-133 mic on my V8000 had far more functions assigned to the keys - most notably scan - I could just press the 2 key when not in a mode requiring DTMF or numeric input to the radio and it would activate the memory scan. On the 2730 I have to hold the scan key on the appropriate bank of the control head then press it again to start the scan bank. All in all, still an excellent radio - W5SSJ
I just bought this radio for this exact feature, thank you for fully explaining it.
Excellent tutorial. Good job! Even I can understand it! Love my 2730a
Very nice video KM4MKL. Thank You! I think I’ve almost made up my mind to buy the ICOM 2730 A.

Thanks for sharing this information! It really helped me out. Using the 2730a for emcom in the Idaho Mountains. 73s
Nice explanation. I'm leaning towards buying this radio vs the Yaesu ft-8900 and this video was very helpful.
Thank you very much KM4MKL, it´s been very useful! 73 from LU1CBQ
Thanks So Much! You made this simple and clarified why I could not find directions in the manual. 😅
Thank you sir. Kinda awesome, the capabilities of this not so expensive radio. Thank you for the clarifications!!
Wow, this was a great presentation.
Very good! Thank you. It made it clear.
Great job buddy, KiloDeltaNiner Fast Racing Hellcat- Dave in Naperville. Well done, gonna be a small project in the spring! Good straightforward vid and I noticed the addendum on Icom's website before I purchased. Best Regards!
I have been an amateur radio since 1994 and I have owned many radios that would do crossband repeat and I have never felt the need to use it not even once.
Just ordered this as my first radio. Decided this weekend to get my license, and am taking the test this thursday.
Congratulations, and good luck on your test! This is a good radio to start out with. Just remember not to hit the transmit button before you have your license in hand. :-)

Buenisima explicacion de cross band en IC 2730
Well done video, I am considering a purchase of this radio and wandering if this would be good for satellite work?
Great radio, great vid.
Thank you. Very good video. 73
I’m a few weeks away from testing, will be using radio for Off-Road desert racing support and photography . This feature looks like the perfect solution. I can locate my 4x4 truck with this mobile unit on a higher location then hike into a ravine without 4x4 access then use a HT to communicate with race control or monitor race communication. Is this feature available on the ID-4100a?
Great vid. I would have liked to see a demo of it working though
Is it possible to set up a PL/offset? This is a great feature, but I've found it's really easy for it to pick up and re-transmit noise.
Excellent video. Will the 2730 let you add PL tones to the right hand side (handheld on 440 and 2730) to reduce chance of interference on the UHF link?
I think this will work, though I never tried to add tones to the uplink frequency.
Just a quick question. I have a buddy who has a Crossband repeater on (Receive freq is 147.575 and Transmit is 446.000). I can't figure out how to program the offset/dup on my IC-2730A manually or in the software. Any suggestions on How to program odd splits ic-2730A?
thank u so much so much easier than my old tyt
I still can't activate the crossband repeater option in the "others" menu. event I tried to push the both of main buttons and moni button and followed by power button, from off position (exactly like you showed me), by many many times..... do you have any other solutions.?
IC-2730E in Spain. I can fallow the secuence whithout any problem (several times-several resets) but never get the the RPT-M option. any help?
Thank you for this!!!!!
Can it transmit on high power on VHF and low power on UHF when using it as a crossband repeater?
I have a new IC-2730A radio set that I bought several years ago and never installed anywhere. I only powered it up to program all my frequencies into it, to duplicate what I have in my older IC-2720H radios. Then it went back into its box, and has been stored in the closet until just now. I tried the button press action at power-up, per your video, and NOTHING happens any differently than when I just power up the radio normally. I'm not sure, but I think the radio may have already been previously enabled for the crossband repeat mode, as I DO get the "RPT M" displayed on the front panel, when progressing through the various EXMENU -- OTHER menu screens. I don't remember having done it myself, as I didn't even know about the crossband repeat function when I bought the radio, but I might have enabled it myself. It has been too long. PROBLEM: When I have the "RPT M -- START" displayed on the front panel, and press the "MW" button to try to get it to the next menu item/option, nothing happens. The screen still just sits there and shows the same display: "RPT M -- START". I can't get the menu to change to the next function, to actually START the crossband repeat mode. HELP! Any ideas?
Disregard my original post. I found the problem a few minutes after posting my original question. I had a severe "Cranial Flatulation (Brain Fart)" while doing the setup procedure. I still had BOTH sides of the radio on VHF frequencies, instead of one on VHF and one on UHF, before I tried to activate the crossband feature ......... Thanks for the video!
Mantap
Terimakasih infonya
Thank's for your information
Much obliged Sir. Easy to take in for an old head!
Edit: Whoops- this doesn't work on the "E" suffix version. Hey-ho, still a good video!
Hi, I'm going to buy the icom 2730E
Question;
The radio has several power settings, is it possible to set one of the powers to a lower one, e.g. 0 5Wat / 1Wat, etc., the minimum is probably 5W
Is the reception of all frequencies good: 118.000MhzMhz / 150.000Mhz / 446.000Mhz is good Regards.
....
In my transceiver there is another option in OTHER->RPT M, its name is HANGTM. Does anybody know what is for?
Im interested in the cross band, the up band frequency is always the same,can I put this in memory or do I need to use the vfo feature?? Great video.
When you setup the Cross Band function, I believe you can select either frequency from a memory slot, or by using VFO.
I'm considering purchasing this radio myself. ANY owner comments are welcome!
I basically want to set up my Jeep as a repeater when hiking. Hitting a far away repeater is a bonus.
I just want to know how to set up a frequency with a 600 offset.
I've done this with two baofengs.
What is this called in the manual? Can't find the word cross more than twice..
RPT M does not come up in this manual

thanks for you
Merci ! 73
hi. i just bought an icom ic-2730a mobile rig. however, i can't seem to add the crossband repeater function using the instruction you posted, mainly pressing and holding the two main and moni button. i turned off the power of the radio first and pressed and held the 2 main buttons and the moni button and pressed the power button until the radio turned on. after powerup, i followed the menu cycle (exmenu, others) but the RPT menu does not appear. what was I doing wrong? please help. 73

hehe answering my own query, thanks to the post below, was able to finally enable cross band repeater operation by removing a diode on the mobile rig. :) 73
Can this transceiver be programmed to self identify?
My question is can the radio cross band repeat to a uhf repeater triggered by a two meter HT? (jus opposite of the setup you have described.)
Good question. I am not sure. I sold the transceiver a while back, so I can't check to see if this would work.
Thanks for posting, I just passed my technicians exam two days ago. Anxiously waiting for my callsign and for it to be added to the FCC database. How long can your battery last with the truck off and this running as a repeater?
Depends on how often the radio is transmitting. It is a simple enough math equation to solve for how long the radio can be sitting idle and another for how long if it is transmitting 100% and then add the battery of your vehicle - or in this case I'd recommend bringing a spare battery to run the radio unattended as you wouldn't want to come back to your vehicle and have a dead battery so you can't start it or use the radio.
As Jason R. said, it all depends on how much you are transmitting. According to Icom the radio draws 1.2 amps in when it's in standby, and 1.8A when it is receiving. However, the current draw increases to 13 amps when the radio is transmitting.
The 2730 needs a minimum of 11.8 volts (approx.) to operate. Since the voltage output drops as the battery discharges, the radio will shut down before the battery completely dies. A healthy, fully charged 12V battery has a voltage of 12.7 volts. You can therefore only drain about 7% of the battery's capacity before the voltage drops below 11.8V. Example: a 100 Amp hour battery, drained to 93% gives you about 7 AH hours of "usable" capacity. You could therefore leave the radio in standby for about 5.4 hours, receive transmissions for about 3.75 hours, or transmit for about 30 minutes before the battery drops below 11.8V, causing the radio to power down.
After removing the 319D diode for the lCOM 2730, the transmitter (TX) became permanently on. When I turn on the signal repeater.
Is there a solution for that?
Thanks for the info. Very good explanation. Randy KD5OLQ
I’m new to ham. And new to this radio. Won’t the car need to be on to keep it draining your battery especially if your on a long net? This is a cool thing though.
You are correct, the transceiver runs off the car battery, and will drain your battery over time. It draws about 10 amps during transmission, at full transmission power (around 120-130 watts, depending on battery voltage.) A typical car battery is 70 amp hours, and generally should not be discharged beyond 50% capacity. That gives you around 2+ hours of continuous transmission before you would need to stop, in order to ensure that the battery has enough juice to start you car. Keep in mind that the current draw is much lower during reception, and while the transceiver is at idle (1-2 amps, roughly.) If you were only planning to transmit in case of an emergency, your car battery might be able to power the transceiver for several hours, if you did not transmit.
The safest thing to do would be to run the transceiver off of a separate deep cycle battery (also know as a marine battery), since these can be completely discharged without damage. You can pick up a marine battery for a little over $100. It would not be all that difficult to install a switch that will swap the power from the vehicle battery to the marine battery, if you wanted to use the transceiver for an extended prior of time while the vehicle is off.
Lastly, you could leave your vehicle running, thus allowing the alternator to power the transceiver. That's not very practical if you are going to be away from your vehicle for an extended period of time, however.
Should this work on the 'E' version as well? I've tried the instruction several times but it is still not activated thanks Johan PG4W
Johan Weijland I have the E version too and can't set up the REP-M option in the menu after several tries. does any one know if it is possible on the Edge version?
I've found out it's only possible in the "E" version after removing a diode and then follow the described steps.

@@lavinenfermero Cross band repeat isn't legal here in the UK, not sure about other European countries.
Seems there are some restrictions put on crossbanding thru linked repeaters due to interference! Any input there?
I am not aware of any such restriction. I am certainly open to comments from anyone who may be better informed. Like most folks, I do not condone any inappropriate use of radio hardware.
Well apparently Arizona Repeater Association cites “massive interference” on their 9 linked repeater system..www.w7ara.org/z/Conduct.Aspx. 8. No crossband or remote base connections without prior permission
from the repeater owner.
This rule insures the system will not be compromised by connections we have no way to control. Such connections can cause massive interference, even though it seems it is working good.
I have to admit..i dont see how a massive interference event would occur if the ht ptt used 70cm to trigger 2m transmit. My logic would tell me it would be exactly like being physically at the crossbanded radio transmitting with the handset! ??
hi..i've tried many times follow your instruction but i still failed to activate my icom 2730..pls help
As I recall, I had to try the first step (holding down the MAIN buttons and MONI button while turning on the unit) a few times before I could access the "RPT-M" option in the "OTHER" menu.
Which step, specifically, is giving you problems?
Pok Jik its probably there. You are likely not setting up the actual repeater frequencies and tones right.
Has anyone used one of these as a remote base in ham radio repeater service? I'm not sure the radio would be up to that kind of heavy duty use.
I only use it for personal use, and only for short periods of time. A reviewer on eHam (www.eham.net/reviews/detail/12180) said he had some success using it as a node radio for an Echolink server at 20 watts, though he added some extra cooling. You may experience overheating if you use it at a higher power in a vehicle, particularly if you don't have very good airflow and/or an extra fan in your vehicle.
I would only use the cross-band repeater function for no more than a few users, and for brief periods of time.
Johnnie Holt THANKS FOR THE VIDEO I HEAR THAT THE ICOM 2730A DO NOT PUT 50 WATTS OUTPUT IT ONLY PUT 40 WATTS OUTPUT IT IS TRUE ? THANKS
I am not sure. I never measured the output.
cross band repeater function work on 1 antenna?
It does indeed.
@@ZaxFrank Thank you for your reply. The radio is of good quality? Sensitivity, sound etc?
Just asking myself why they lock this function...
Because it's not legal everywhere.

"There's a very important and poorly-documented procedure you must do to your radio before using this feature, but I'm not going to demonstrate it here, because I already did it." is completely antithetical to the concept of an instructional video.
Your remark is in bad faith. How about listen to the rest of the video instead of popping off clever quibs?
To remove diodes and be a contortionist to activate a feature is nuts. WTH is iCom thinking? These transceivers are expensive to the customer and to hide or exclude certain features is not cool!
What diodes are you talking about? Its a keyboard mod.
Go download the instructions - the addendum is not really vague- its these same steps www.icomamerica.com/en/support/kb/article.aspx?ArticleNumber=EC3C525899
@@n0trk It's only a keyboard mod for the US model (A) not the EU version (E). Anyway, cross-band repeat isn't legal here in the UK.
