[Amps] My 813GG amp works

[Robert B. Bonner]

Scott when I had my alarm system installed we had it done completely in shielded wire. You may be able to quiet it down with ferrite beads or toriods  on each end of the wire runs.

If not you will be deativating the panel when you operate. I do not envie your situation. I had many friends with this problem over years and that's why mine is in shielded wire. 

I still won't turn the alarm on until I'm done operating just incase it is more sensitive activated. But my fire system is hot all the time.  I guess I got something for my 5 grand.

Subject: [Amps] My 813GG amp works

 Hello all,

Taking some advice about putting that homebrew 813 GG, that I bought, on
the air for a while before I try to modify it for other bands. I to try
it on Saturday night/Sunday morning around 1230 AM for the first time.
The wife was snoozing in bed, I thought... why not give it a go...

So I tuned it up into the dummy load on 3810 kHz, driving it with 65
watts out of my transmitter through my antenna tuner to match the
transmitter and the amplifier, I flipped the switch the watt meter
indicated 650 -700 watts out of the amplifier and into my antenna,  got
a "sounds mighty fine" signal report... and then our house alarm went
off... And it wasn't even "armed"

Needless to say, the wife got out of bed... she said, well I guess it
works, but can you not use it again until you figure out how to keep
that from happening again...

I guess the alarm system didn't like that amount of RF, but the amp
works!

Now I need to solve that alarm problem...
