I have a small longwave AM transmitter for sale. It works from some 190kHz to some 420kHz.
It uses two 813 tubes - so I estimate the RF power of a few ten Watt.
These days a lot of cheap Russian G813 tubes are offered at eBay for a small sum.
They will be good for spare when the US-tubes will fail somewhen - if you do not find US-tubes for a reasonable price.
The modulator and the power supply is inside the transmitter cabinet. The transmitter works from 110Vac
but if you use 230V in your location I can offer an additional step dwon transformer.
The transmitter is contructed to tune short wire antennas. A few ten meters will be OK.
This transmitterwas used in WWII as a ground station transmitter on small air field for coordinating
incoming planes. You need to connect a microphone and start transmitting.
Is there anybody interested in this transmitter? My QTH is North Germany. The transmitter came in a
small wooden crate which I still have. The total weight will be some 40kg! (Witout the additional 230/115-transformer.
