Can't receive VHF channel 78

[Hudsonian]

My Raymarine 53 Vhf radio broadcasts on all channels and seems to receive on all except 78, which the local RC uses to commnicates with racers. I have written Raymarine asking, "What should I do to get the radio to receive channel 78?" but haven't treceived a response.
Do you have any suggestions? I can purchase a NOS Raymarine 53 Vhf radio on Ebay for $100, which is cheaper than having Raymarine fix it.

If it were mine (and not under warranty) I'd replace it.

Make sure your radio is set for USA channels and not INT (international). INT channel 78 is a duplex channel. USA channel 78 is actually designated as 78A and is simplex.

What Eric said. On many radios it is very easy to get in/out of US/international modes accidentally, and the indicator is usually a very small "US" or "INT" that looks like a flyspeck. Without the manual, you may never find the secret keystrokes to do it.

Raymarine is not the quickest at email communication, give them a call or see if the manual is available online. I have called Raymarine and had my question answered in minutes.

Perhaps they responded on channel 78...

from the manual ...
"6) MON/ 1/25 Key5) WX/INT key
-. When WX/INT key is pressed and released, Alarm 1 is heard and Working CH
/Weather CH are toggled each other.
-. When WX/INT key is continued to be pressed for more than 2 seconds, Alarm 1 is
heard and frequency selection mode(US,International or Canadian) can be
changed. There are 3 types of frequencies selection modes,US,International and
Canadian. The frequencies selection mode is changed like USA--��CAN--��INT.
-. While the monitor operation is in use,Dual monitor and Triple monitor can be
changed."

on International, CH 78 sends at 156.925 and receives at 156.875 !!!
on US mode, CH 78 sends and receives at 156.925

sounds like you've got it in international mode and need to switch to US mode by using the WX/INT key

Thank you, Ron. I'll hit the WX/INT this evening.

What should the typical range be for a VHF radio
