No, I think only a few have this feature. I have an Icom W32 that has it but I have not tried to set it up, no need. I don't know which others, but I'm sure if one has it it will be stated loudly, and will cost more.

Certainly not
And cross banding with an ht is just begging for problems.
Unlike mobile radios, hts don't have cooling fans or large heat sinks so they could easily be damaged in a cross band mode.
Hand helds are designed for short range, short duration transmissions.
Attempting to do otherwise will usually lead to disaster.

The single band models most definitely don't!

I am not aware of any HTs currently on the market that do crossband repeat. There are some that offer dual receive.

Perhaps you mean do all HT's have support for repeater offsets/split operation, And the answer there would be that yes, just about all of them will.

I mean no insult if you are actually asking what you said and did not mean otherwise but I'll explain the difference below just in case you did ask the wrong questions.

I believe that Crossband repeat would mean the radio acts as a repeater receiving in one band (Such as 2 meters) and transmitting in another (Such as 440).

Repeater offsets or Split operation means that within one band you can receive on one frequency (147.39) for example and transmit on another (147.99) without having to manually change frequency. When you're not transmitting your radio listens on one frequency the repeater output, when you transmit the radio switches to the repeater input frequency. Once you release the PTT key the radio switches back to the repeater output.

This allows real time repeater operation where if you operated a simplex repeater you'd transmit, the repeater would record what you send then when you release the PTT the repeater would retransmit what you said. the result is that anyone within simplex range would hear you twice and you'd hear your own transmission come back to you.

Again, if you already knew this there was no insult meant, but if you had your terminology confused hopefully this will help.

Thanks
Eric

The FT-51R from Yaesu offers full duplex and cross band repeat.

Of course it's a discontinued model now...

My guess is they dropped it from the lineup because there really would be very limited circumstances in which a crossband repeating HT would be useful. I can see it's usefulness in mobile or base stations, but not in an HT.

I have a FT 530 that will cross band repeat, I don't remember if it's in the menu setting or if I have to do a mod.. That should tell ya how much I would use it for that! However setting up a dual band mobile would work great for that, but then I didn't really help answer your question much.. But to try and answer the question I read: no, but some will or do.... J

Pay attention to this comment, he is absolutely correct.

I learned the hard way as a new ham in 1997 with an FT-470. I love the radio but puting it into cross band mode fried it in about 30 minutes tops, or how ever long it took me to walk to the corner store and back.

I have two FT-470's had one on the bench at home connected to base antenna and the other with me.

Now I have two dead FT-470's soon to be resurrected into one as the cost to rebuild the other outweighs the cost of replacement by a good margin. As quoted by Yaseu it was going to cost $235 and that was before the screen froze and turned black, the second one just has minor abuse issues, and can be saved from the parts from dead subject "A"!


Dont use the Handheld as a crossband repeater, I have had much better luck with using the mobile/base as such for a much longer time(about 4 months now, dedicated) and have no issues with it besides the design flaw that all had until the second release.(TM-V7A)
