Always use T-SQL and Tone on your cross band simplex channel to prevent others from accessing the cross band repeater easier. It also prevents noise from being repeated.
Great video. I use CBR a lot for things like Sky Warn activations. I have found two problems. First is the distant (not the car) repeaters tail. It keeps the down link up and prevents you from being able to come back until the tail drops. The other problem is regulatory. On the down link, your CBR repeater in your car is transmitting but it never carries your voice. Therefor, you never ID through it. I know of two easy solutions to the repeater tail problem. One is to keep the tail as short as possible. The second solution solves both the tail problem and the ID problem. That is, I set the radio up to only repeat the up link signal. Then I set the HT up split band to receive the distant repeaters output frequency transmit on the CBR repeaters up link frequency. Then add "cross band repeat" to my ID. The down side of this approach is that you don't get the boost from the CBR on the down link. But it does overcome the low power of the HT. Also make absolutely sure that you have a tone and time out timer set on your CBR radio. You can lock you CBR radio and the distant repeater open causing them to overheat. Give it a try though. It's relay fun and is a powerful tool for service work.
Awesome video, thanks! The Terminus comment was very cool. A couple of thoughts about crossband repeat are that repeaters can be a little bit of challenge to repeat into because the repeater signal has to completely drop before you are going to be heard and it might be best not to crossband during a net or nets because the radio will be transmitting almost 100% and that could put a strain on the radio particularly if set at full transmit power.
+George DeLoach Good points. In a prepper scenario I would setup a simplex cross-band for local comms and not cross with a repeater. In this video example I needed the repeater because my neighbor (with license) was not around. I needed someone to answers.
Many regions have frequency coordination groups. They usually have assigned frequencies for cross band repeat. For example, in Wisconsin, W.A.R. specifies 446.4125 thru 446.4875 (25 kHz) for this function. SERA in the Southeast specifies 445.7375 thru 445.9000. Crossband repeat is used during swapmeets, etc. Consider using CTCSS TSQL on the ID-5100. Al - WA9RYO
Hey, I can get the bluemont(in virginia actually) repeater from town! I will have to keep an ear out for you. I was going to play around today with the crossband, as it would have been very helpful for the CCAP bike ride that starts in Winchester and heads south. I ended up in a hole where my FT-70 couldnt hit the assigned repeater for my position, and ended up attached to my truck the entire time.
How did you program the handheld? I was told to tx uhf 440.000 and set duplex to split and offset to 144.000 (examples). I was told to set a tone so no one else can use my cross-band rptr.
LOL... Come on.... All Who Arrive Survive right? Great video, I have been eyeballing the 5100A for some time but have yet to pull the trigger. I have been trying to decide whether on not to go with an HF mobile. I really like the idea of cross band repeat, but HF would be nice too. Keep up the good work. 73, Chris K4CGB
+ngpeters Yes - that is a cool feature. I stumbled across that reading the manual. I still have to make the video but with the control head removed you can still control allot of the radio's functions with an Android device (via Bluetooth). It's a radio with lots of prepper applications.
Great video demo, thanks for posting. Two questions, what mounting bracket are you using for the ID-5100? Can you crossband repeat using DR mode in any way?
Great video. Quick question: How is the 5100 control head mounted? Is that a custom mount (not the icom steel plate, but how it is connected to the dash)?
+William Arcand Just posted a video on that topic two weeks ago czcams.com/video/LAKVbIhoeB8/video.html I also have a complete installation playlist on the ID-5100.
+Commsprepper Doh! I have been behind on watching my youtube subscriptions. Watched the video above. I have a control head I need to mount soon and was looking for some ideas. I have a different vehicle than you, but you got me thinking. Thanks!
Great Video. I just picked up a 5100 and was playing around with the cross band repeat function. I never heard the 5100 self ID, is that a setting I missed somewhere? Keep up the good work, 73, Matt
I have enjoyed using cross band repeat on my Yaesu 8800. works like a dream. using CBR allows for lots of potential. great video. lol at "don't go that way" I wonder if that ever crossed Rick's mind?
Can cross band repeater work without going through a repeater? What is simplex cross-band, and how does it work? Demo? I want to set something up where the radio in my vehicle becomes the mobile base station repeater to service a group of local handheld operators.
Cross-band repeating does not requiring connecting to a repeater. Simplex cross-band would be spit VFO (A/B), all radios would TX (lets say) on VHF, and listen on UHF. Perhaps a future video topic. vehicle acting as repeater - that's what cross-band repeating is.
+TRprepper Thanks TR. I see lots of prepper potential with cross band repeating for sure. It was a great weekend at the retreat, even got some range and ATV time in.
I have my base Kenwood TM-D700A set up for cross band, because my I can't hit my favorite repeater with my HT or mobile this far out. I just enable it when I leave the house. Hams should remember to practice using features on their radios. You may not have the instruction book when you need it. Thanks for the Demo!
What happens if someone other than your party chooses the same simplex frequency and accidentally gets repeated over the repeater? Use of tone squelch on the 5100's simplex frequency ?
I used the cross-band feature in the ID-5100 that's installed in my truck. I'm using the HT to make a simplex connection on UHF and cross-band to VHF repeater pair on the mobile.
Arent you running the cross band radio off your car battery? If so, what is the duration that you run the cross band radio? Do you have a secondary power supply? If you cross band all day or several hours - are you worried about the battery. Or do you use another method of power?
Ok great. The reason I ask is I have an Alinco dr735t with cross band repeat as a base on a Comet GP-9 and another in my truck on a Diamond 7900A and several HT's Still trying to be careful using them as I know you can overheat them easily and damage them in cross band mode.
Yuh I have done this. I like how the Kenwood has like standby settings that turns most all off when in cross band mode and how yours will unplug the face. Not sure if mine does that. Haven't got to test it a lot as I work a lot of hours. Will delve more into it when able. Thanks for reply
+Roy Amberg Thanks. These 6 min. videos have 40 plus min. of mistakes and bloopers. For this one I had to park the truck next to the house in the shade because the sun glare was so bad.
Oh I see. Like the old advertisement of the refrigerator back in the fifties the lady closed the door and it don't latch properly. Do the advertisement over to make a good one. I understand. You make it look so easy
+Roy Amberg Oh... my videos have lots of cuts before I have something I can edit and make look whole. But it's still fun to make them and I always like making them at the retreat location (no people around to make noise or ask questions).
HI i have a 5100E but in menu OTHERS there isn't the voice REPEATER MODE only 4 voice are present Information, Clone, touch screen calibration, and reset......WHY?
+Tracy Reed You can bury your gear but how would you know when it's safe to take it out? I don't worry about EMP. Solar EMP (in my opinion) would be too weak to affect equipment. Power lines yes, equipment not likely. Man made EMP - game over.
I know it's been a few years since you put out this video, but TMARC has an auxiliary set of frequencies for this purpose from 433.000-435.000. It's probably best to use those. For more info: www.tmarc.org/bandplan.html BTW my QTH is Fairfax Station. Great to see another Virginian on CZcams. 73.
I crossband repeat through my Kenwood d700 regularly and find may hams either don't understand how it works or are unwilling to try it because it involves more than just turning on a radio. I have been in roundtables during commute time and due to nobody letting the repeater drop, have been unable to participate until everyone got destinated and got off the air. "I wonder where Steve went to". "He was in the group a few minutes ago" "I don't know, Steve are you still out there?" "Nope, didn't hear him. Guess it's your turn Jim." "Thanks, I guess Steves portable died on him". The whole time I'm there waiting on the repeater tail to drop so I can get in and participate in the discussion but, ..... I don't know if it's a Baton Rouge thing where hams in South La don't like to pause or drop a repeater or if it's common everywhere but it is a major issue with xbanding around here.
You should ALWAYS use PL rx and tx on your UHF frequency!!! If you don't, you run the risk of someone (or something) unkowingly activating the xband repeater!! PLEASE CORRECT YOUR VIDEO!!
Great videos on the ICOM ID5100, very well done and helped me get more from my rig. Keep up the great work!
Outstanding video! Your series on the ID-5100A has be extremely helpful in my deciding to get one! Keep up the great work!
Thanks. Glad they have helped.
This is a nice demonstration of how cross band repeat works! Great job!
+Gear Hammer Thank you!

If you are worried about someone finding your UHF frequency and hijacking it you can add an access tone to your ID-5100a
Good point! Thanks for adding.
Ha. I've been a TWD fan from day one. Very cool setup. Thanks for the demo.
+diycentral Thanks for watching and commenting. Wish I could have added some walkers to the video.
Hank, great demo and I use it like that regularly. I also have done crossband DSTAR as well.
Thanks for the comment and watching.

Thank you....I updated my repeater list thanks to your video
glad the video helped.
Great setup there :)

Nice demo. Thanks.
Awesome video, thank you! Is there a minimum distance that I should stay away from my IC5100, so as not to overload the receiver?

That is pretty cool being able to remove the radio head have it function as a cross and repeat!
+ngpeters Yes - that is a cool feature. I stumbled across that reading the manual. I still have to make the video but with the control head removed you can still control allot of the radio's functions with an Android device (via Bluetooth). It's a radio with lots of prepper applications.
Great video demo, thanks for posting. Two questions, what mounting bracket are you using for the ID-5100? Can you crossband repeat using DR mode in any way?
You cannot cross-band in DR mode. The mount is WORKMAN PED1 HEAVY DUTY 6" PEDESTAL CB RADIO MOUNT BRACKET. They are on Amazon.
So you had to use FM from the HT up to the mobile, even though both radios are capable of DV simplex? That's a bummer.
I just listened to some SoCal guys on 449.500 setting this up. Very cool stuff
Very cool thanks for sharing !
Thanks.
Great video.
Quick question: How is the 5100 control head mounted? Is that a custom mount (not the icom steel plate, but how it is connected to the dash)?

Nice demo well done.
Thanks!
Can you remotely control the 5100 from your HT with DTMF tones? Is there a set TOT when in crossband?
You cannot remotely control and I am not sure about TOT.
WA4TSC is a beast of a repeater. I use it almost daily.
I will be back on that repeater in 17 days (overseas right now).
Great Video. I just picked up a 5100 and was playing around with the cross band repeat function. I never heard the 5100 self ID, is that a setting I missed somewhere?
Keep up the good work, 73,
Matt
+Matt LoPresti the radio only runs the cross-band in analog mode. No ID taking place
Outstanding....
Was the RX noise due to the UHF simplex link?
+Bruce Wayne It was between my HT and the truck, I was a bit around the side of the mountain.
I have enjoyed using cross band repeat on my Yaesu 8800. works like a dream. using CBR allows for lots of potential. great video. lol at "don't go that way" I wonder if that ever crossed Rick's mind?
+TangoTexan You are the fist one one to comment on that - thanks (I thought it was funny). No I don't think that ever crossed Rick's mind.

+TRprepper Thanks TR. I see lots of prepper potential with cross band repeating for sure. It was a great weekend at the retreat, even got some range and ATV time in.
Been a while since you have visited with the ID-51a, are you still running this radio any at all? Just curious, as I have acquired a 2nd hand one.
You helped me out, thanks
Glad it helped.
I have my base Kenwood TM-D700A set up for cross band, because my I can't hit my favorite repeater with my HT or mobile this far out. I just enable it when I leave the house.
Hams should remember to practice using features on their radios. You may not have the instruction book when you need it. Thanks for the Demo!
+KA5IVR Good point on the practicing. Thanks for taking the time to watch and comment. CommsPrepper
What happens if someone other than your party chooses the same simplex frequency and accidentally gets repeated over the repeater? Use of tone squelch on the 5100's simplex frequency ?
+Andrew O'Brien You can use tone or digital squelch to mitigate that.
I know this is an old video but how did you receive the repeater (vk2rbm) when not on its tx frequency? Did you set the handheld to split rx/tx
I used the cross-band feature in the ID-5100 that's installed in my truck. I'm using the HT to make a simplex connection on UHF and cross-band to VHF repeater pair on the mobile.
So, you keep your DC power on all the time? Doesn't that drain your battery? Do you have a secondary power supply?
I don't get the question, what DC power?
Arent you running the cross band radio off your car battery? If so, what is the duration that you run the cross band radio? Do you have a secondary power supply? If you cross band all day or several hours - are you worried about the battery. Or do you use another method of power?
Very cool
Where did you find out that you can remove the control head? I spoke to Icom today and they said it isn’t recommended.
+roostershooter76 in the manual somewhere. May have been the advanced manual.
If it isn't recommended, then why did they add the feature? Sounds like you talked to someone didn't know what he's talking about
What were you useing as an antenna?
Can you use this feature to crossband to simplex frequencies or do you have to link up to a repeater on one vfo or the other?
yes.
@@Commsprepper I'm going to assume Yes means I can go simplex to simplex without a repeater being in the chain somewhere?
Ok I am a little curious and couldn't find it in here in comments. How far was you from your truck in miles approximately?
three miles but that means nothing. VHF/UHF radio systems are line-of-sight (LOS), so range is dependent upon the two antennas seeing each other.
Ok great. The reason I ask is I have an Alinco dr735t with cross band repeat as a base on a Comet GP-9 and another in my truck on a Diamond 7900A and several HT's Still trying to be careful using them as I know you can overheat them easily and damage them in cross band mode.
Turn the power down on the Alinco. If it's in the right location you should need allot power.
Yuh I have done this. I like how the Kenwood has like standby settings that turns most all off when in cross band mode and how yours will unplug the face. Not sure if mine does that. Haven't got to test it a lot as I work a lot of hours. Will delve more into it when able. Thanks for reply

brother what ya gonna do when they fly the EMP plane over ?
But that was awesome !
+Theredneck Prepper Not sure. I don't make enough money to bury extras for all my gear.
I'm curious: What do *you* do for that situation?
+Tracy Reed You can bury your gear but how would you know when it's safe to take it out? I don't worry about EMP. Solar EMP (in my opinion) would be too weak to affect equipment. Power lines yes, equipment not likely. Man made EMP - game over.
Was it digital on the simple side?
Analog
all looks to work as long as you know what your trying to do
+Roy Amberg Did I miss something? Lots of options and applications with cross band repeating.
I was trying to say if you understand how to use the equipment you can get it done
+Roy Amberg I hope the video covers how to setup the ID-5100A. I don't want to give out bad info.
I know it's been a few years since you put out this video, but TMARC has an auxiliary set of frequencies for this purpose from 433.000-435.000. It's probably best to use those. For more info: www.tmarc.org/bandplan.html
