HI Mike and the group.

Yes I cut the trace either side of the new HPF board, exposed a bit of the trace and jumperd onto that.
You need to cut the second trace from the PA side. They are in order:
1: TX pwr to the PA circuits via R89
2: RX path (between K1 and K3 relays. (CUT AND INSERT HERE)
3: TX pwr to the LPF bank.
4: RX pwr to the receive circuit (R18,R38...)

I picked up GND from the 2 unused caps C216 and C210
