recently picked up a nanovna as well. I am having a lot of fun characterizing antennas and cables. suddenly it’s clear to me why this cheap 144mhz whip on my desk is only useful on a very narrow set of frequencies.
I live on a small remote island. Over the past number of years there has been a boom in heat-pumps here due to government subsidies. A local company appeared and was happy to fill the demand for new units. Eventually the new installs dried up and the company disappeared.
This winter there has been a number of desperate pleas on facebook for people seeking repairs on their heat pumps and split units. Unfortunately, the nearest company who can service these units is a half day ferry away.
It does exist in other forms with WWOOFing, farm stays, etc.. The problem is that while farm work looks simple, there are important skills that need to be developed before a volunteer or guest can be useful on the farm.
For example, my first WWOOFing gig asked for at least six weeks so that I could become somewhat useful and offset the costs of food and shelter.
