I have teamed up with another broadcaster who knows Panaxis transmitters inside and out, in fact he was the one who provided Ernie the fixes for his FME FM transmitter back in the mid 80's. He also upgraded our AM transmitters by adding a trimmer cap for the crystal, and came up with a replacement for the MPF102 transistor that use to blow all the time. The transistors were also upgraded for improved output in our units, along with an improved power supply.
We are looking into recreating the Panaxis AM transmitter with the added modifications. If you ever owned a Panaxis, you know they were very loud, capable of 300% modulation. they also had a 50 ohm output and were not bothered by the presence of a FM transmitter like the Procaster and Sstran, regardless of power (We tested our Panaxis next to a 1000 watt FM transmitter), our Procaster will go into self oscillation in the presence of a 100mw FM. We are currently researching parts availability, and looking into adding PLL.
We think our recreated Panaxis will be far superior to the Ramsey AM25, and easier to build than the Sstran, along with a standard 50 ohm output which could used in carrier current.
With AM stations going dark in increasing numbers, and FM being crowded out, the market place needs more choices in AM transmitters that are a little easier on the budget. Not everyone can afford to shell out $800 for a certified transmitter.
We will keep you posted on what we come up with.
