Hi Alex, First what frequency are you trying to set up? I have worked on hundreds of Micors and I find that if you have a low power 50 Ohm wattmeter 1 0r 2 watts , it works the best. Terminate the exciter with the wattmeter and 50 ohm load. The ideal power is 400 MW out. 250 or 300 is to low. On the slugs that fall out , use a rubber band on the side to hold them into place until their set, then use wax to seal them. Heat up the wax to move them, if you have to. The exciter is freq. sensitive, and only tune about 6 MHz. You must change the bridging Cap to get it to resonate. Unless the coils are broken, don't waste your money. A Grid dip meter would be a big help. If you are trying to get to six meters , the caps across each coil must be changed , the values are to high. Hope this helps. Ron WA6UNM

I find that the coils in the mobile exciters don't hold their ferrite slugs properly and they fall out, slide and just don't tune right. Also, it seems that the output transistor goes bad if the exciter operates mistuned from a ferrite slug sliding out a little or just not staying tuned. Has anyone tried replacement coils...or is the mobile exciter not worth the effort? ... Alex Yahoo! Groups Links Yahoo!
