Greeting from the Caribbean of the north, got up to 24 yesterday and already to 18 today. I won’t bother wasting any wax on my body board though, I am sure it will be more useful for the skis in short order.

Pathfinder asked in comments about the situation with the CKOK transmitter. I thought I would answer here.

CKOK piggy backs on the CBC AM antenna which is a low power job [40 watts] hung between two 35 foot cedar poles 300 feet apart.
The original aim was to buy a 400 watt transmitter and bodgy the power output so the antenna could handle it. Unfortunately no one makes anything lower that 1Kw in Am transmitters now days. A 1kw would not only damage the existing antenna wiring it would also over power the CBC signal.

So the plan now is to go FM and still maintain the AM until such time as they no longer are able to be repaired.

Going FM will mean that the cabins in outlaying areas will not be able to receive CKOK as they do now, that is why maintaining the AM as long as possible is recommended.

Going FM is also not cheap, the transmitter will not be the biggest expense, that will be the antenna and all the inspections of the tower [CBC again] and getting riggers in to install the antenna.
Preliminary work was done prior to the previous Executive Director leaving. It would be prudent for OK to follow up ASAP as the old AM jobs could go any time. Then they could last for who knows how long.

We could go with a 1 kw AM using a whip antenna, but again, that would over power the low output of the CBC antenna.

For some odd reason, there are a spate of LPB parts on Ebay right now. Saw two boards and a crystal today. Also a 40watt/80 meter Hallicraft AM/CW transmitter that needs a crystal.

There are reasons why not using an old system would not be appropriate for OKS Pathfinder. One would be being a broadcaster you have on air commitments. Also there just is the lack of local on call expertise available.
