It would be nice. Now most of the baby monitors are going digital, conditions might improve a bit. There is also a channelised LPD allocation on 40MHz. There are other LPD things on there, so maybe still as busy in some areas. 40.675 would be ideal for the clansmanophile, because it means you can use the 349 too, which is easier to hide carry around!

I think the non-ham is spoiled for choice these days with 27MHz FM (and soon AM/SSB) legal for local or DX on HF modes like sporadic E, and then 446MHz for playing with tropo lifts too. I don't see much call for a just-under-6m band TBH. Even the amateurs don't exactly make a great deal of use of it.

Had a little net going on 49.860 the other night with a few locals. It's a nice clear band in my area these days.

Watson/Diamond 2000 works well on there!

All of my local 49Mhz baby monitors seem to have gone to landfill thankfully, and the latest generation of parents seem to have bought the 2.4Ghz variety of digital stuff, so 49Mhz is as clear as a bell here now, and no friggin' PLT noise on it either. On very humid and sticky Summer days I get US signals banging in at S9+, they seem like emergency services, but it's been a couple of years since I've heard any.

Hello
I have had a 49 MHz link/gateway on FRN for over a year now.
The link puts out a beacon every 15 minutes with station info, including E-mail address.

No replies yet, the out put is very low, when I go out to play 27MHz from the top of the hill I can some times hear the beacon.

It’s nice to see some others like Delboy playing around with some of the other frequencies we have available.

Not absolutely sure, but it's in milliwatts.
I have Realistic and Maxon radios on this frequency and the only references to output power quote '10,000uV meter@3 meters (FCC Max.)'

I wouldn't have thought so - 6m starts at 50Mhz, although I'm sure someone on the forum may know a radio that can cover this

The license exempt 49MHz frequencies are:
Channel A - 49.830
Channel B - 49.845
Channel C - 49.860
Channel D - 49.875
Channel E - 49.890

My widebanded Yaesu ft857 covers 49mhz. A couple of locals occasionally use 49.860 for chatting on.

The Icom 706 series cover these frequencies also. Be careful to keep the RF power down very low though as you're transmitting out of band and the 706 doesn't like it. Too much TX power and you could damage the filter board.
Never, ever, ever....bloody anything ever!

Far too many radio's to list here. But I do own a legal one...

I had a baby monitor in my daughters room when she was a newborn. (She is 27 now) It operated at 49.86mhz. When parked in front of my house, I could hear her room monitor on an FM radio at 99.7. I programmed a car stereo preset to that channel.

You would have been hearing the 2nd harmonic frequency from the poor quality transmitter in the baby monitor. Pretty amazing how well some can be picked up.

Take a look at this for an explanation of harmonics:

Found my old Star Trek communicator. Tx & Rx on 49.1 - 49.5 MHz via VFO. It doesn't have a detachable antenna, nor does it have a direct entry keypad or two-line lcd display. There's not even an led flashlight at the top. My UV5R has all of these features & a far greater range of operating frequencies. And just like the communicator, it can handle VOX on semi-duplex! However, according to my Starfleet Annual (1978), my communicator can transmit & receive signals from 1000 miles away. So how come my trusty Baofeng can't get through to my house from the supermarket that I'm currently queuing in ? It's only quarter of a mile up the road and I need to know if the kids prefer Coco-Pops or Frosties ! First World dilemma. Lockdown's driving me crazy !

I think the communicators use sub-etha for comms, whereas the Baofeng uses RF. That would explain the diference.
