RF Broadcasting at Home with CRT and LCD via HDMI and a PC! UHF vs VHF vs No Antenna vs Built-In!

All the acronyms money can buy, but can we transform the Urza Master channel into a local UHF/VHF station with this little PCB? Let's play around and find out!
I know absolutely nothing about what I'm doing, but we can learn together the best way - trial and error!

Need to set the CRT TV to ANT instead of CATV.

[@JohnSmith-hc5hy]

Hello, SIF is the position of the sound carrier offset within the specific broadcast channel. For NTSC the SIF should be set to 4.5Mhz to place the sound carrier in the correct position. Thank you.

[@urzamaster]

Awesome, thank you!

[@chrisreynolds6331]

The channel numbers on the CRT TV are just allocation slots for stored channels, not the UHF channel number. You need to search tune or enter the frequency manually via the menu.

[@urzamaster]

There are some good tables online! Great tip!

@@urzamaster They'll be just as the past person stored them. They're just presets. They won't correspond to anything. I was thinking, for the love of God, go into the menu and do a scan! (or enter the RF channel number as appropriate)

this reminded me of old radio shack 2.4ghz A/V transmitter going room to room. had static in picture but was cool for the time

[@urzamaster]

@@jay1o1o oh shoot! I forgot about those! I'm pretty sure I had one back in the day.

[@JesusChristhasrisen-i4r]

This is a cool product. You need to boost the signal up and make your own stiaon

[@urzamaster]

Absolutely. That's my goal!

[@IainDavies-z2l]

You need to put an aerial into the CRT tv, as the gain of the TX is not very high so not to interfere with anyone outside your property. The 6 Mhz. setting is for the Vision and sound separation in the UK with 8 Mhz UHF channels the separation is 6 Mhz but don't know what is is in the US. Without thus being set correctly you won't get sound.

[@urzamaster]

Awesome, good to know!!

Need antennas connected to both TV's. In America, the channel bandwidth for both VHF and UHF channels is 6 MHz; with the SIF set to 4.5 MHz. You're receiving the video on the wrong channel because you have channel width set to 8 instead of 6 and not getting the audio at all because it too is offset improperly. Keep playing with it, it appears to work,just wrong offsets. Good luck.

[@urzamaster]

Thanks for the info! Yes, gotta get some bunny ears going

[@starlite528]

@@urzamaster you could just get a large paperclip and straighten it and that will get you something.

[@randymoyer5351]

Put a real antenna on the CRT then select ANT instead of Cable in menu settings.

[@urzamaster]

@@randymoyer5351 yes, definitely on the to-do list. Follow up coming soon!

[@se7vennld]

The tv transmitter had a telescopic antenna.. Use it !

[@urzamaster]

I've got it extended now. More content on this to come!

pretty cool, where didnyou buy? 😊

[@urzamaster]

I got this off of ebay.

[@nickwallette6201]

Having a TV tuner claim to be on Channel 1 is a red flag that something probably isn't what it appears to be.

[@gnuorder]

Is it outputting a digital signal the CRT can't receive? I know it says analog on it but that may just mean it can transmit an analog signal. I can't find that particular device.

[@urzamaster]

Supposedly, it's pure analog, but it may just be a weak signal. I'll have to play with it some more.

[@pavlovsky0]

You need a blonder tongue with coax.

commercial rf amplifiers, lol!
