Hi there,

It's been a while since I have used my scanner...

Basically I am an apprentice falconer, don't worry i'm 34 and taking things steady...

But I do not have £450+ to buy a dedicated reciever to receive the telemetry signal being transmitted on 173MHz...

What I have have done is coupled my Yupiteru MVT-7100 scanner brought in 1995 to a 3 Element Tuned Yagi, so that I can receive the incoming signal from a 2 stage transmitter on 173.237.0 MHz...

But after 500 yards the signal to noise ratio is starting to drown out the signal, with the squelch turned off I can pick the signal up at approximatly 2 miles but the noise is pretty much drowning out the signal...

I was thinking of using a band pass filter to help clean up some of the noise etc but not designed anything to work with a scanner... most things electronically I am fine with but for some reason I am a bit hesitant with this...

The BNC is 50 ohms so I presume the whole design needs to be below this thrershold but does that also include the Yagi?

Any help or advice would be greatfully received...
