I have been away for awhile but I don’t remember seeing anyone mention Quality Radio Productions before. They have several Jazz programs that are available for free to any non commercial station. Take a look at https://qualityradioproductions.blogspot.com/
Any one know where I can find crystals for an older Hamilton Rangemaster transmitter? Picked up a used Rangemaster but Hamilton says Bomar no longer makes crystals and need to buy adapter ($99) plus module.
