HI all We have a Hylas 49 and it is fitted with an Icom MC802 HF radio we have been updating all our navigation equipment prior to setting off on our adventure but have been having big problems with the Raymarine AIS650 transponder we think the problem is with the RFI but wonder if anyone has has similar problems and what they did to solve them Thanks in advance Derek and Carolyn Hylas 49 Manketti 2HJT4
