[Hallicrafters] RFI

[Langston, Mike]

Hello everyone,

 

I got on 75M AM last night testing out a new antenna (multi-band trap
inverted vee for 80/40/20 I picked up at HamCom). No AM activity that I
could hear at 3880 so I dropped down to about 3875 and broke in on a SSB
group. The antenna seemed to be working fine.

 

Then, the XYL appeared in the shack holding the phone. Seems our next
door neighbor was calling complaining that I was causing their security
system to go off.

 

I was transmitting using a B&W 5100B barefoot at about 90 watts output.
This rig has a built-in low pass filter. No tuner was in the line. The
rig loaded up fine. The antenna is fed with coax.

 

This is a new one on me. Anyone ever have trouble with RFI getting into
a security system wreaking havoc? Any suggested fixes or
trouble-shooting I could do?

 

For the hallicrafters list, I was receiving on an SX-101A.

 

For the Johnson list, my Viking II is about ready for an on-air test.

 

Thanks in advance for any help.
