PA3CEG 23 CM GS35b PROJECT|
This project was based on the latest information (April
2001) from Alex RW1AW. Some of the tubes dimensions in the cavity where hard to
find, so they where made from massive material. Its takes a lot of time to make
all the parts from sketch and finish them for assembling. Special attention, to optimize the airflow in the
cathode compartment to cool down this part of the
GS35b. Planning to cool the air stream later on with a Peltier element,
otherwise water cooling must also be possible. There is a lot off heat to
exchange, due the low efficiencies on 23 cM.
After a few test, the air cooler must changed due the
distance (air gap) between cavity and cooler for proper cavity tuning.
