UPDATE, well that was a very odd situation in my shack tonight, now all 3 radios are working as normal, got a contact in Hungary and was long enough to change over to use each radio, all ok now, i striped the shack and check every contact and so on.
GREMILNS IS ALL I CAN SAY, NEVER HAD THAT HAPPEN.

Annoying a problem like that when it goes away before you find the cause. Glad you are back on air again.

It could be something as simple as coax too close to, or touching another radio's coax, some induction loop feedback might occur in TX.
Can happen when you don't have a shack Earth that all your radios should be connected to.

My bet is on a duff coax connection, either a dodgy patch lead or maybe water ingress at the antenna end or, as I've had once, the coax stretching and actually coming out of the PL259 at the antenna and when the exposed braid made contact it was OK but when it didn't I got all the lovely common mode RFI you expect.
