A few years ago I saw a nice fancy indoor antenna at an op shop, when connected to a TV it got a great signal. I didn't buy it, which is something I now regret.
My videos about the videosender got a lot of views (at least compared to my other videos). Time to see whether it was the videosender, transmitting in general or the CRT TVs that were pulling in the views.
That's awesome. When I was a kid, I actually used to have a VCR that had analog cable signals. I know that is a bit different than what you were trying to do, but I still think it is awesome I got to use my VCR for TV signals.
Thanks, yes it works much better when plugged into the TV's RF socket like it's designed to do. It's very handy that most VCRs have an RF output, they can be used to convert a composite signal into an RF signal for old TVs without a composite input. I managed to transmit using this VCR a lot more successfully in a later video, with an antenna connected to the end of the cable.
You can also use an RF adapter that has an RCA/composite input to transmit a signal if you still have a TV without RCA/composite capabilities. I can still receive a VCR signal with TV, although I need my DTA box; in addition the TV and the VCR need to be set to the channel designed to view the VCR in TV mode. This most likely would use channel three or four; on some VCR's you can set that up at the flick of a switch. I can even use a channel to record a program if I wanted to, which I actually tested during my college winter 2019-2020 break at home. The channel in my program test had to match the one for viewing the VCR on TV. My VCR's default setting is channel three and it can not be changed with a channel switch. To perform my initial test (which actually worked) I used the dual DTA box setup mentioned in an archived setup guide on fcc.gov. This setup also required an RCA/composite cable. The program I "recorded" (for a minute) was the ABC talk show "The View" (which I don't watch, though).
@@Computerman859 Yep, I've transmitted with my RF modulator too in a later video. A few of my TVs don't have composite inputs so it is quite useful. Our VCR's RF output annoyingly is in the UHF band which my older TVs can't receive, I do have other VCRs but they need fixing currently. We were recording TV to VHS tapes until about the mid 2010's when we got a digital recorder, but I think we just had the composite output of the set top box going to the VCR, our set top box didn't have an RF modulator. The dual DTA box setup's great, I might do that with a TV that has a composite input.
@@toomanyinterests All of my family's TV's (but one) are modern with HDMI and composite inputs, with the oldest being mine, made in 2008. The CRT TV is mainly used to play vintage video games and my brother used it the most; the TV was made in 2004. A lot of older TV's from the 80's had the option to receive TV from VHF or UHF. I know this because my parents owned two sets from that decade for a while. My dad had a Sears 2100 series mono model made in late 1986, and my mom had a Panasonic 19" TV (mono also) made in late 1984. The Panasonic TV also had the capabilities to watch TV over the air, but the Sears TV required cable. My dad removed those TV's from the house during the digital cable transition in 2014, the same year my family stopped using the VCR to record programs.
@@Computerman859 The Philips TV that's in this video my parents bought new in the 90's, it was our kitchen TV until our bigger LG failed spectacularly with a bang. After a few years with the 20" Philips as our main TV, we got a 32" Mitsubishi for free. It was so big it didn't fit in the car, we had to bring it home on a trolley! The vertical deflection failed in that after a year and a half, so the ever reliable Philips returned. Later that year in 2019 my father bought our first flatscreen. Over the past few years I've been picking up old CRT TVs, I recently got an 25" Sanyo from the early 80's which is now the lounge room TV. Hopefully the Philips can remain the spare TV this time.
Interesting, my TVs from the 80's can't receive UHF. Then again, I think they're from the early 80's and UHF TV broadcast only began here in 1980. That Sears TV sounds odd, never heard of one that only works on cable TV, did it have the cable decoder built in or was it just a monitor? Analogue TV broadcasts stopped here around 2009/2010 but we were too cheap to change TVs.
I have seen a lot of videos showing this working on PAL VCRs but never on a NTSC one. I think I might try this sometime tonight!
Looking forward to seeing how it goes! I just bought another aerial at a garage sale so I'll be able to do this again hopefully better.
@@toomanyinterests I don't have a second arial but I have a Sony Watchman portable TV with one built in so I will use that!
@@Dedicatedtolivinginthepast That should do the job. Just realised my National pop up portable TV has a built in aerial so I didn't need to buy another one after all. Oh well, always good to have a spare and it's an interesting design.
I've tried the same thing with two passive indoor antennas and it worked similar to your setup. Sometimes I also got a colour picture. It works better if you use a channel which is not used by a TV or radio transmitter in your location.
I got a better result using two antennas, but only when they were quite close together. This VCR outputs UHF only and all the stations it operates on are still used for TV. I do have other VCRs and an RF modulator, I used the modulator in a later video and it worked reasonably well.
A 1:50 Raffaella Carrà. Io ricordo anche Guzzanti per la parodia oltre a Pronto, Raffaella?, anche la parodia di Zig Zag con Vianello e Mixer con Minoli.
Ricordo anche il gioco del pranzo in cui metteva le foto con Mantoni, Carrà e il Windows XP.
La stessa cosa viene rifatta da Insinna con la prima puntata del pranzo é servito il 28 giugno 2021 su Rai 1.
Ricordo anche quella del ragazzo di campagna con Pozzetto.
You can make a perfectly matched antenna by splitting the TV coaxial cable into a simple dipole antenna with the correct length for the channel you are trying to transmit.
Thank you for the suggestion, next time I need an antenna I'll do this.
Awesome I'm glad it worked for you! Have you seen my videos of this method? (But using 2 sets of antennas)
Yep, you got a good signal.
That's cool
Thanks, it works much better with two antennas
It can actually work quite well, but as you said, you do need to put an antenna on the end of the cable. I do something very similar on my channel, ruclips.net/video/zEJ67vMjHKU/видео.html I'm using a modulator, but that's what you've got built into a VCR anyway.
I have an RF modulator which I've used to connect a TV without a composite video input to a set top box. I've also been trying out a VideoSender, a small TV transmitter which seems to work pretty well.
I have one that looks like it and it has a subwoofer
I assume you're referring to the TV, this Philips doesn't have a subwoofer. Yours must be a better TV to have that added feature.
@@toomanyinterests Yes, I own the format and type shown in the video (pawer vision ) 21 inch
@@Achrafdizer That's cool, that is the same TV. I suppose I'm pretty sure this one doesn't have a subwoofer, but I've never opened it up. I would be pretty surprised if it did though as it isn't even stereo, it only has mono composite inputs. Very interesting, there must be some slight model variations.
Keep your mode switche clean out in your VCR player everything proven people like myself cleaning out mode switches in VCR players and they start working again with out no problem's
Thank you for the advice, I have a few VCRs that have issues and probably need the mode switches cleaned.
Your welcome no problem
You can go online and say how clean out a mode switch in a VCR player and every other videos online will come up what you need to which online if you don't know what a mode switch is and the video's online will show you what a mode switch is
I'm gonna guess that you are a Sagittarius.
I agree. He definitely seems like a Sagittarius to me.
Sorry to disappoint but I'm not a Sagittarius, I'm a Virgo.
@@toomanyinterests😅🤣😂
People like myself wolk over to the post office and everything i get off eBay like my cleaning tapes vhs movies VCR belts VCR players everything goes to the post office where it goes to it doesn't come to the house and the post office is behind my house everything goes to the pobox
Yeni mi öğreniyorsun😂

What you are doing here is somewhat illegal because it messes with the FCC. You’re broadcasting a signal that’s not licensed to be broadcast. The proper way to transmit a signal from the VCR to the TV is to simply connect a cable from the RF out on the VCR to the antenna/cable input on the TV. No antenna needed, and it works better too. Just be sure the TV is tuned to channel 3.
I know that it is meant to be plugged in without the antenna, I wanted to see if the signal strength was strong enough to transmit over a very short distance. The signal is so weak it won't cause any trouble, the VideoSender would be a far greater concern and that was a legal commercial product. And the FCC isn't where I am.
Tuning the TV to channel 3 won't help with this VCR, it only outputs on UHF.
