TV Sound Radios

[MarioMania]

2 Radios I am using is Emerson TV Sound PM3912 and Sony WM-FS556

Kinda odd I was listening to KFBK 93.1 on my Walkman on Ch 4 (71.75) Digital Tuning

I got my TV Sound Analog Tuning to see if I get the samething

I tuned around Ch. 4 nothing ..But I got KBEB 92.5 B925 around Ch 4 ..I got like Mix 96 96.1 KYMX

It ended with 107.9 the End KDND Sacramento...I'm in West Sacramento

I want to see if it works as a FM recievern, like Ch 2 is at 59.75 MHz and Ch 3 is 65.75 MHz -- Put the Transmitter at 62.5 & see if it the TV Sound Radio would pick it up

Not legally. Part 15 FM transmitters are only allowed on the 88-108 MHz FM broadcast band, and with slightly higher power (roughly 0.5 mW ERP) on the 902-928 MHz ISM/ham band. I'm willing to bet you don't have a license to use any other kind of transmitter. In fact, unless the rules changed recently, no Part 15 device of any kind is allowed on any VHF TV channel. It would work if it were legal, though.

My Max is 400 ft

Just do a experiment on it

I'm not sure what you're saying, then. Are you saying that you have a transmitter that can do +/- 75 kHz deviation (standard broadcast) FM that transmits on the low VHF channels, and you want to not only see if you could hear it at all, but at a range of 400 feet?

You can certainly build one from an FM transmitter kit and modify it accordingly, but it won't be legal to use in the US. Or am I misunderstanding what you're trying to do?

Yep 400 ft. or Lower on 56-87 MHz at Very Low Power

There's a always to Mod a CZH 05B FM Transmitter for like 400 ft with a Low Power Antenna

probably due to heavy overload, and IF image issues in a poorly designed receiver.

When I was little, my dad made me an AM radio transmitter that could go about 50 feet and it covered the whole house.

It was such a thrill to hear my own voice coming out of my radio.


And speaking of FM transmitters, I couldn't help but think of that cheesy commercial from the 70's for a thing called 'Mr. Microphone'.

It was actually a little FM transmitter.

You may remember the commercial. "Hey, good lookin. We'll be back to pick you up later!"

Hawaiigar,here is the modern version of your
childhood am transmitter:

You can find them in the automotive section of any
Walmart-Walmark-Walmart's 😊.

They say that if you hook up 19 inches of wire thru the
(conveniently) provided slot in the battery cover to one
of the negative battery springs it will enhance the
range,too.

From the title of this thread, I was hoping to find out if there are any
portable radios capable of receiving the audio portions of today's digital
television broadcasts... That would include both the UHF and VHF Rf
channels.

IIRC, there's no such thing as a separate audio portion of a digital broadcast. Everything is multiplexed onto one stream. It's probably possible for a DSP chip to decode the audio portions of each subchannel, but there's either little market interest or it's too expensive.
