4.1 software and "split" antennas? Band interlock?

sdelmont

Upgraded to 4.1 and now I cannot use two antennas on the same band, like I used to on 3.x.

Firmware version 4.1.6, FlexRadio 6600 on 3.5.9. Configured with Port A -> ANT1, Port B -> Ant 2. FDX enabled.

If I configure Slice A to use ANT1 for both RX and TX, then the AG works as expected.

But if I use ANT1 for RX and ANT2 for TX, then the AG "blocks" Port A (red color on all the buttons).

Same thing happens if I use two slices, Slice A with both RX and TX on ANT1 and Slice B with both RX and TX on ANT2. I can switch antenna ports just fine, as long as each slice is on a separate band.

As soon as the AG sees both ports on the same band, it locks one of them.

Is this a bug? Is there a workaround, other than downgrading, or operating the AG in manual mode?

Or is this band interlock here to stay?

Downgrade back to 3.1.5

I keep telling people to NOT upgrade yet. There are features that are in 3.1.5 that are not in 4.1.6 such as the ability to disable protection and use two different antennas on the same band or build a super switch. I do not know if 4.1.6 will be the official released version of AG v4 or if additional features will be added (4O3A needs to answer that) but once an official version along with matching TG XL version are sent to Flex and then vetted, stay on the older versions.

Unless there is a specific feature new to 4.1.6 that you need and until Flex approves AG 4.x, stay on AG 3.1.5 and TG XL 1.1.20.

Yeah, just downgraded. Will keep an eye on future releases but staying on 3.1.5 for now.

And if you have the SO2R TG XL make sure there is a corresponding TG XL firmware release.
