(Araucaria) RES: IRON HAM CONTEST

[Thomas Carlsson]

Hi Brother that feels so Young!

Well it is a question of try and error. I had clamp-on ferrites. put some 5
or more in series and moved between cables and checked where it made
difference.
Check Coaxes and Rotor control cables also other control cables going up to
the antennas.

If there is extra length on the cables in question, best is to use Big
Toroids (Outside diam 2,4") and let the cable pass as many turns into the
ferrite as possible, 4 passes is possible with RG213 with connector. This
is MUCH better than  Clamp-On ferrites, but Clamp-On are good for location
of the problem.

Note Ferrites (F) in series adds dB attenuation value F +F+F++etc
But number of turns through a Toroide (T) increases T x nsquare!

Identify Where biggest Interference problem is and teransmit and listen
accordingly when making the tests.

NOTE Material #31 is the BEST!!!!
