You release your mic key, and now your dual band is listening on 2m and transmitting on 440. The problem is, it will not switch out of listening on 2m until the transmissions stop. So if there are a number of people talking, the repeater never stops transmitting and you cannot talk to the repeater.
Yeah, you can't let your crossbander hear the repeater.... also raises ID issues if the repeater signal is (re)generated at your site not using your call.

I use an HT and my crossband repeater is an FT-8900 in the truck. I use tones on the truck input so no one else can key my truck unit.

I TX with CTCSS from the HT on 440 to the truck.
Truck TXs on 2m to the repeater with their tone, if required.
Truck RX frequency for 2m side is set out of band, so even though the dual band has to be active, it will never hear or repeat the repeater.
The repeater does its thing and I can monitor the repeater directly on the HT.

I can hear the repeater from much further away than I can quiet it with the HT, so this usually works.

This lets me roam within HT TX range of the truck and within HT listening range of the repeater.

I'm not understanding what you mean by this.

Yesterday I set it up again with my HT on 440 and the ID-5100 A band on 440 and B side set to W3MUM repeater. We walked around the park about 1/2 mile away through trees and I was able to get the W3MUM repeater loud and clear. I heard other hams talking through the repeater and it was coming out my HT as we walked around the park. I was able to activate the repeater from my HT.

Am I missing something or doing something wrong?

Maybe your radio is different.

But most, if the repeater is transmitting, it will not "hear" you on 440 to activate the repeater.

If the repeater is not too busy, it will be OK. But the repeater normally holds the transmitter up for a few seconds after the person talking unkeys. And if someone keys up, during the "hold up" time, the repeater stays up.

In the old days, the CARA repeater, during drive time, would not drop for hours.

6 1/2 ft (social distancing) is approximately 2 meters (popular HAM vhf band).

I feel that I have reached "pass" on the Technician material, so I've moved on to study for the General.

I'm currently on Part 5 (of 9) of this series. The presenter (not the YouTuber picutred) gives a good practical presentation of the material, at least from my point of view. I also have the ARRL General study manual.

Good, there is so much overlap in material that taking the General exam will seem like just a continuation of Tech.

What digital voice modes do you have/operate on, and what reflectors/talkgroups do you use most often?

I have a D74, so DStar via rf. But I also have a hotspot and can cross-mode to dmr & fusion.

I've done a look of lurking on various reflectors and talk groups, but they are all pretty quiet.

Nice!

are there P25 phase 2 repeaters in this area? I thought that at one time Phase 2 was trunked.
