Hello to you
Hi there Herbie.
Welcome to the forum from me in the UK , bit of a time difference there but i expect we will bump in to each other at some stage, communication knowledge is always of value, the old stuff offers as much input as what are high tech future does, there was a thread on here not long ago, a carer wanted comms contact around the home and yard, but an open frequency so they could keep a safe contact for the impaired/ disabled person.
The use of a baby monitor was being used, to cut a long story short the carer wanted extended radio range, or comms contact, an example where your skill could have maybe helped.
Any way there is always loads of good topics and projects, so i hope you enjoy it as much as i do, see you on the boards Herbie. Dave.
