Extending Range of Harbor Freight Ding Donger
« on: May 08, 2019, 05:11:05 PM »
Alan,
You are the electronics man...

I have four Harbor Freight Ding Dongers for telling me when a Rattus Rattus is eating my peanut  butter. The one at the top of the hill just doesn't indicate 35 yards away and in the house.

Any experience modding the Ding Donger for increased range of these things?

I'll look around to see what I can find.

I have an Omega compressor. If you're a fellow Guild member, and you pass through Roswell, NM, I'll fill your portable tank as a courtesy.

I can send you one so you can look at the innards. :)

The main issue with all of these devices, is the fact they use the same frequency bands. The older 27 MHz, 49 MHz, and 72 MHz, are still used to some extend. However, all have been replaced by the 313 MHz segment. This segment also has vehicle fob controls, garage door controls, a number of entertainment remote controls, and a host of others. If you use a spectrum analyzer to listen across the band, all you hear is trash! This trash reduces the range of all of the devices, no matter who made it. And, they're limited to the output power, so boosting the power isn't the answer. What you need is a wired system.

Sprinkler wire is cheap, and easy to bury if you know the trick. The rest is easy to come up with. Let me see what I can whip together.

You are the man! Sitting on the edge of chair in anticipation!

One feller on GTA claims you can tap in a long antenna to get extended range but that didn’t sound right.

Last night I moved the receiver outside my sliding glass door to get better angle of view and to eliminate  the wall in between. Half a hour later I missed seeing a Rattus that spent two minutes at the station. Arlo got it but the flashing light of the ding donger did not flash. If I move the receiver another ten feet closer to the transmitter it works. But it’s now out of sight. I guess I could hook up the speaker again but that will wake the dead.
