Room Monitors

[nickcarr3151]

Does anyone know of a room monitoring device that operates @ 254 Mhz?  I found one in my neighborhood.  I haven't listened too long but I was able to drive around and I.D. the general street that the signal is coming from.  It's < 1.5 miles LOS from my discone.

A friend and I were thinking of some Chicom ripoff using the odd UHF frequency.  I searched Amazon but most seem to be using either WiFi or 2.4 Ghz RF -- and if they are using RF, most generally don't mention the frequency range.

There are some overseas produced cordless phone bases in the 225-400 MHz range.  Could be something similar.   If the same thing, they ran a good amount of power.

Back in the 80s I used to hear someone's cordless phone base unit (I believe this was on 1610 kHz or so?) from a distance of about 10 miles. Must have been a foreign model with a lot of power.

Same here. Probably a bit lower than 1610 though.
These were definitely not legal where I lived.

The old Midland cordless phones from the early-mid 80's used 1610kHz for the base to handset, and 49MHz fro handset to base. I turned mine into a radio station.


The base output apparently was coupled back in to the power line for antenna so I was able to pick it up several blocks away as long as I stayed in the same alley where the utility lines ran.
