Orange Birch Bolletes

I take they are edible, I never tried them. Had some Blue Legs in the past. Absolutely delicious. I keep meaning to learn about native mushrooms and delve into a bit of foraging.

I suspect you are getting a voltage drop across the common switch. Could be elsewhere but I'd start with the switch. short the switch out with a wire link and try transmitting. If all is ok with the...

Wearing a tether

I personally would not wear a tether, even under the circumstances described. if the boat were to flip you could be in danger of getting snagged under water. I would, however wear a PLB on my life...

False alarm

That is hilarious. Thanks for sharing that story. Just think, you could have been steaming for hours on an ever increasing search pattern looking for yourself, like Winnie The Pooh and the Heffalump.

Not likely unless you stray very far south and a tad east. My stomping ground is South Devon, mainly the Dartmouth area. I see you are an engineer so a rewire should be no problem. If you need any...

Aquatic Armachian

Good to hear from a fellow Armachian and ribster.

There are some lovely boating areas in that neck of the woods. I have done a fair bit on the north coast over to the Isles and back. Great...

Vhf procedure

A very useful aid for both experienced and novice crew. It is notable how tongue-tied one becomes when the proverbial hits the fan.

antenna

Exactly right. that's all you need. A good antenna grounded to a good ground plane, creating a 1/2 wave dipole, and, of course, a decent VHF transceiver.

Don't try connecting 2 antennas, you will almost certainly damage your VHF. It will create impedence mismatch, an unbalanced antenna circuit, very poor VSWR and ultimately damage to your RF stage.

Sounds like you have covered the quality issue. What tests have you done on the coax?
I still think you have a coax/antenna issue. If you haven't already done it, I would recommend doing a VSWR test...

The problem with 1.5 to 2 mm is that it is very thick cable for nav equipment but it certainly will handle the current. You can always double up for high current stuff such as nav lights.
