QRT since March 20 due to brocken Elevation rotor MT3000
Problem is the gear see fotos :
The reason it stopped working was the little brocken wheel (see above)
The wheel on the main axis also looks not good, some missing tooth caused
play in elevation earlier
Repair by 2nd try. The first time I
used the new gear motor direct at the chain. Now I have added a 4:1 chain gear
which works now excellent
the new chain gear in the back, I added a gear in the front and on the
right a new gear motor for a little more then 100 Euros
complete elevation drive
Some days later one of my 3m BC-DX antennas (commercial trash, only 1
year old!! will never buy again!!! ) gave up.
The boom was brocken direct at the mast clamp and earlier one the
elements was brocken see pictures
brocken front part of a 7el 3m bc antenna a closer look to the crack of the boom
a closer look to the crack of the element, that’s the 3rd brocken
element from 4 antennas within 1 year.
(optimized profit, no quality) The next 3m-DX antennas will be homemade,
for sure!!!
