Re: [Repeater-Builder] Exec II input problem

What are you using for a signal generator?  Some generators leak a lot of signal and might have more than .35 uV of signal radiated on the outside of the coax.  When you break the shield path, this higher signal level might get to the radio. Another post mentioned that the RCA connector uses a

Hi Jim, I am using a Wavetek 3001. I also have a MVP here with the same helical filter and it doesn't exhibit this. Hence fairly convinced that something is going on with the Exec's filter. It seems like the signal is getting better because were loosing the loss of the filter stage. Update n

Sometimes the conductivity of the tuning screws to the casting becomes questionable. There is a conductive grease that a lot of GE shops used to eliminate that issue. Chuck - Original Message - From: "wb8art" To: Sent: Saturday, May 30, 2009 11:06 AM Subject: [Repeater-Builder] Re:
