RE: [Repeater-Builder] Min FREQ Separtation, VHF rep, No Duplexers
as it must be the correct distance between an antenna and another one if I use bansplit of 5MHZ?Joe Montierth [EMAIL PROTECTED] wrote: --- Steve Bosshard <[EMAIL PROTECTED]>wrote: Once upon a time I asked Lloyd Alcorn up at Wacom that question. Best I recall 60 ft is the maximum distance on a tower that you can seperate antennas. Further seperation will not yield additional isolation because of the coupling within the tower itself. Number wise memory tells me that the isolation at 146 Mhz and 60 ft. was around 60 db - just enough maybe with a clean tube transmitter and very selective receiver to get by, and maybe not. Horizontal seperation was not nearly as effective. Seems like 85 db of isolation was the magic number at 600 kc. Regards, Steve Isolation wise, vertical is much superior tohorizontal. For the example we're working on, 100 fthorizontal would be the same as about 14 ft vertical.To me, it would be easier to get 14 ft vertical, than100 ft horizontal.Joe__Do you Yahoo!?Yahoo!

RE: [Repeater-Builder] Micor mobile exciters
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.

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!
