Hi Nick,
Interesting reading about your time out in Central America, sounds like you had a great time. You probably operated the transmitters in the tropical bands, either 3.3MHz or 4.8MHz, due to the high static levels found on the Medium Wave band.
The stations in the tropical bands can usually be received very well over here in the UK during the winter months.
It’s a pity you didn’t take out you call, because Saudi is pretty rare on the air these days, be nice to hear HZ occasionally.
73 Paul.
