[Lowfer] WC2XSR/13 off the air

[Ralph Hartwell]

The subject line says it all. One of the output MOSFETs shorted out and
shut down the transmitter. The probable cause was excessive
drain-to-drain voltage caused by running the transmitter with a light
load and elevated drain voltage. The transmitter will be off the air
until I can repair the RF current transformer in the antenna tuner
cabinet and replace the shorted transistor. While the transmitter is on
the bench, I will make some planned modifications to the front panel ,
oscillator circuit and the oscillator power supply. It is unknown at
this time as to when the transmitter will be back on the air, but
hopefully within a week.  Station status is always available on my
station log page.  While the TX is down, I'll be listening.
