Hi Chris, Just wanted to say a huge thank you for your advice on linking my garmin 152 gps to my icom m421 dsc/vhf radio, I followed your instructions and hey presto it worked first time, I called swansea coastguard for a radio check and was coming through weak but readable, considering I was in bridgend on dry land with buildings all around that seemed pretty good to me. once again, MANY THANKS for your help, Regards,
Steev.
