[CA] [CA11] AIS & VHF less reception after upgrade

[Steven Swart]

Hi - I had a lightening surge that affected my old system - C80 chartplotter and some of the seatalkng network . The AIS700 worked fine, so kept that linked.
I replaced the system including an Axiom 9 and also put in a new Ray63 VHF (old one was the Ray215)
Now my reach area for both the AIS and VHF is considerably less that before. I understand all about the aerial Mhz and height etc, but it's only the radio and chartplotter that changed the reception and TX on the radio. Would this radio perhaps draw more power, causing the problem?
