Re: msf 5000
The tuning a MSF5000 is not for the faint of heart.
Go to Repeater-Builder.com and spend a few hours reading the articles and manuals that are posted on the website, then tune and realign exactly as described in the manual and you will have a repeater that will provide years of reliable service.
Also might want to swap out the 2 electrolytic capacitors in the power supply section of the uniboard, these are a known problem point.

On the receive SMA connector on the RF tray. You can use a coax jumper to any type of 50-ohm termination and it'll tune fine.w5kow5ko wrote:I have a msf 5000 uhf its on 444.000mhz going through the tune up it says to put a 50 ohm load on the preselector input does that mean on the receiver input or the antenna input???
